In Talking Radio 1985 – 2018, we will be looking at the promises made in 1985 by the then Independent Broadcasting Authority (IBA) when they claimed to be issuing new community radio licenses and clearly stated these licenses would be going to new people and not the current established radio company’s.
Horizon Radio first then JFM, Solar and others took notice of what the IBA was saying and ceased transmissions and applied for one of those new licenses. At this time we had millions of British people behind us and had proved there was a need for our kind of broadcasting. Non of the stations that worked hard to show there was a need for alternative broadcasting was considered for a license, which begs the question Why.
Talking Radio Today A Future For Broadcast Radio ?
A future for broadcast radio ?
Try it – Give a portable battery powered transistor radio to a 16 year old, and ask them to tune in a station – you’ll find they struggle, even to switch it on.
In 1965 any teenager would have been very familiar with and have listened avidly to their “transistor”. Even in 1975, as Japanese HiFi boxes arrived in the UK and commercial FM broadcast radio finally began, anyone under 25 knew how to tune to 95.8MHz. Unsurprisingly, the very same people half a century later, are the ones still listening to the radio, on FM.
In the 21st Century, over-55 year old’s fund commercial broadcast radio. Advertising agencies know this demographic ‘cohort’ intimately, they watched them grow up and they are a rarity today, a target audience with disposable wealth.
Gen-Z, born post 2000, a smaller and poorer cohort, access music and information via their mobile phone. They select, share and stream, they do not listen to linear audio determined by a ‘DJ’ …mate. They enjoy clean, distortion free, high definition sound and pictures. They choose the highest quality settings automatically and they find the nearest ‘Wireless’ WiFi, so they don’t have to pay.
Simply put, broadcast radio is in perfect synchronicity with its ageing audience, and like them, it will reach its expiry date. Radio has no future audience.
Talking Radio. Unless, the ‘radio industry’ reinvents itself.
Unless, the ‘radio industry’ reinvents itself to reach the digital audience it will pass into history like the thermionic valve.
Governments around the World have noticed the end is in sight. They are gleefully selling off the frequency bands once used by broadcast TV and broadcast radio to the mobile networks. Unless a broadcast service can be made commercially viable and a case made for its continuance, then soon there will be no frequency to broadcast on.
Perhaps it would be simpler to give up. Pass the baton to Spotify and mobile network operators, allow them to absorb what was once referred to as ‘broadcast’, and become just another ‘multicast-stream’.
The same question is being asked in broadcast television. Who needs ITV-3+1 ? Seemingly, only those who seek electrically operated stair lifts, comfy armchairs, and fully catered river cruises.
Why not just become another supplier of content for Amazon or Netflix ? – It worked for Clarkson.
Back in 1982, HRL set out to widen the reach of radio, we aimed to serve a set of listeners ignored by the artificially small number of licensed FM stations in London. We discovered rapidly there was an audience and our relatively simple equipment could provide adequate coverage on FM. Sadly, our vision and our experience was not embraced by the establishment.
Today, HRL would like to propose much the same vision, we don’t give up, but we are running out of time. Radio can survive, it can have a digital future and serve a wider audience; but only if the broadcast radio industry gets its act together and quickly.
The first wireless was sound broadcasting, way before TV and cellphones. The business case relied on an expensive transmitter network, matched to cheap, plentiful, readily available receivers. A future digital broadcast radio system must meet the same criteria, it must be cheap and available for the consumer; yet it must outperform FM, it must satisfy the high resolution, highly selective, informed and connected younger audience.
It’s a tall order.
FBR (Future Broadcast Radio)
Those readers of a non-technical nature might wish to turn away now before we delve into the abbreviations of digital technology. As we outline our proposal for the next generation of broadcast radio.
Given that the mobile device is the obvious target receiver, FBR must deliver the following;
- Low power consumption, ideally a zero increment over other usage.
- Reception in extremely difficult environments, where mobile data and voice cannot operate.
- Performance which exceeds FM in every respect.
- Quality which matches the highest definition audio.
- Information performance that equates to internet access.
In brief, it needs to work ultra-reliably, sound superb, in a basement, during a snowstorm, while using little or no battery, for a week.
A big ask.
We believe the solution is to leverage the market power of our cousin – broadcast terrestrial TV. Adopt the same digital transmission technology and enable all the enhancements embodied therein to reach mobile devices.
Namely, DVB-T2-Lite and DVB-NGH with MIMO at UHF and L-Band, configured to the most robust FEC and Modulation modes; it could deliver remarkable coverage.
It disturbs us at HRL to discover the UK government has long since sold off the 1452-1479MHz L-Band frequencies, internationally allocated to terrestrial digital broadcast radio. Ironically Vodafone, the new owners, recently paid 100 times the price achieved by Ofcom, they now intend to ‘re-purpose’ this band in a unidirectional mode ! It is to be deployed as a ‘Supplemental’ downlink-only for 3G-LTE traffic using very high order modulation schemes that require a high receiver C/N to operate.
The logical approach to the deployment of FBR is to share both the cellular network structure and the frequency bands that best suit reception in mobile devices.
Ideally, the same antennas in the mobile device would serve both the 3G-LTE data network and FBR. With FBR uniquely capable of its proper role of BROADCASTING, GenZ customers will see added value in their hand immediately.
FBR overlaid with a shared 3G-LTE cellular network would create operational synergies, lower costs and open up opportunities for local, niche and subscription stations.
It’s entirely feasible to transition to a FBR system that reaches a larger audience with more choice, and better performance. You never know one of the stations might be called Horizon.
If you’re still reading this; have an interest in the continuance of broadcast radio, and are prepared to get off your contented backside, we’d like to hear from you.
Talking Radio. Appendix:
For the curious.
- DVB-T2-Lite is the 2nd generation Digital Video Broadcast Project’s Terrestrial specification – Lite is a sub-set aimed at low power consumption in mobile devices.
- DVB-NGH is Next Generation Handheld which embodies the above.
- MIMO – Multiple Input Multiple Output is a terminology that describes the use of multiple antennas and data streams at both the transmitter and receiver.
- UHF – Ultra High Frequency, by this we include the band between 470 and 690 MHz, the diminishing remnant of the once mighty TV broadcast bands.
- 3G-LTE – Third Generation Long Term Evolution, the correct name for “4G”. A bolt on, of a bolt on, of a stretch.
- C/N – Carrier to Noise ratio. The purest of them all, a measure that compares a coherent man-made radio carrier to thermal noise.

Chris Stewart looks back to radio before the boats of the 60’s. The BBC, Independent Local Radio (No More). The Unlicensed Broadcasters of the 80’s. How the name Pirate Radio came about. The corruption/political interference in those early days.
Radio has always been looked down upon as the poor relation of television, yet was discovered long before TV and would be our first line of defense, should another larger Salisbury happen in any major city? Taking Radio will look at the current business model of corporate radio and show how radio stations like Capital, part of the Global owned network along with Bauer Media owned stations are killing radio off.
If you love radio like we do, time has come to voice your opinion or in ten years, radio will be a thing of the past. In Chris Stewart’s Talking Radio you will find facts that will amaze and distress you, coming soon.

Digital Technology Audits
Full Independent Digital Technology Audits Without The Technical Hassle!
Our digital technology audits provides an evaluation of your school / Trust's network focusing on elements such as topology, network & device security, device management, data recovery and licencing. Our audits are designed for us to focus on the technical parts but the outcome for you is core strategic recommendations without the technical jargon!
If you are already outsourcing your IT and question the current status of your network, it may be the ideal opportunity to get an unbiased view. Our audits typically last one full day onsite and will be conducted by a member of our central management team along with one of our service technicians. As part of the audit we will deep dive into all known parts of the network from the top-down taking live information based on the current infrastructure and noting down possible recommendations. Once the audit visit has been completed, our central team will then compile a formal audit report to be submitted back to your school / Trust. This audit will cover each section of the audit in more detail and also provide possible short, mid and long term strategic goals which could be implemented by the school to bring it up to industry standards.
What a standard audit roadmap looks like
From start to finish, our central IT services team will manage all communication and discussions around the audit. As part of our pre-audit checks we will communicate with the school and ensure that all of our DBS information is passed over prior to us starting on site.
For single school audits the roadmap will be slightly streamlined, however the process will remain the same. Once the visit has been completed and the formal report has been complied, we will arrange a review & handover meeting to go through the findings and strategic development points.

Good day everyone,
I've been trying to run a SPECT simulation using GPU while using an STL
file for the phantom. I read that it needs to be voxelized phantom and
source so the simulation can work when using GPU. So my question, is there
a way to make a voxelized phantom using STL file?

Apstrata allows a developer to send push notifications to iOS applications by abstracting the Apple Push Notification Service. Similarly, it allows a developer to send push notifications to Android applications by abstracting the Firebase Cloud Messaging HTTP protocol. In other words, apstrata serves as a push notifications provider for iOS and Andriod applications.
Apstrata makes it really simple to enable push notifications for your applications through a REST API. Here are the steps that need to be taken for this purpose:
- Create a configuration for a "mobile application" using the "AddCertificate" API (upload the required certificate and password as both Apple and Google require that push notifications requests be authenticated).
- Create channels and subscribe device tokens to them (every device has a unique token or identifier) or push notifications to a run-time specified set of devices ("ad-hoc")
- Send notifications to a channel (push notifications will be sent to all devices subscribed in the channel) or to the ad-hoc set of tokens


56.10.05 - Network Access
To define network access.
Policy will be reviewed once a year by the director of Systems and Network Operations and will be approved by the chief information officer (CIO) every odd-numbered year.
Local Area Networks
Supported LANs are those designed, installed, and operated by the Enterprise Network team. Devices such as computers, zero clients, phones, printers, scanners, storage devices, and videoconferencing systems may be connected to a network outlet within a supported LAN with the approval of the director of Systems and Network Operations.

This software must be configured to receive regular virus signature updates from the anti-virus servers administered by the TTUHSC El Paso information security officer and his/her staff.


For the purposes of this discussion it will be sufficient to treat noise figure as a relative figure of merit. The conventional wisdom concerning noise figures can then be summarized as follows:
Noise figure is expressed in dB. Smaller numbers correspond to lower noise and a greater ability to detect weak signals. It is not possible to have a noise figure less than 0 dB. In the context of amplifier noise figures, 8 dB is extremely poor, 5 dB is poor, 3 dB is reasonable, 2 dB is good, 1.5 dB is very good and anything below 1 dB is truly excellent. Mixer stages are generally noisier than amplifier stages. Each stage of a receiver contributes to the overall noise figure of a receiver, but the relative contribution of each stage is reduced by the cumulative gain of the preceding stages.
Two consequences of this conventional wisdom are as follows. If the first stage of amplification has a reasonably high gain, it will effectively determine the overall noise figure of a receiver; and the use of a stage of low noise amplification before a noisy mixer will greatly reduce the impact of mixer noise on the overall noise figure. Both considerations support the use of a stage of low noise amplification with reasonably high gain prior to the first mixer. How much low noise gain is needed? Most engineers would say somewhere between 10dB and 20dB.
With this background, consider the FCD Pro. The LNA of the E4000 has a nominal noise figure of <4dB. This is acceptable for consumer TV applications. Depending on the overall configuration of the receiving station (including the antenna, and perhaps a preamplifier) it may also be acceptable in the context of the Fun Cube satellite project. However, when the FCD Pro marketed as having general broad-band capabilities there are applications, including ham radio applications, for which a noise figure of ~4dB is unacceptably high.
The designers of the FCD Pro seem to have responded to this noise figure problem by using a low cost Si MMIC to provide lower noise amplification in front of the E4000. The BGA2717 MMIC has a nominal noise figure of 2.3 dB at a frequency of 1 GHz. This is acceptable. It is significantly better than ~4dB, and people who need a noise figure below 2 dB would probably expect to use a special-purpose preamplifier that uses a more advanced (and more expensive) technology, such as pHEMT technology.
The noise figure trap is that lowering the noise figure from ~4dB to ~2.3 dB increases the gain in front of the mixer by up to 24 dB. This results in the default gain of the FCD Pro from antenna to mixer output reaching close to 60dB (with up to +24dB from the BGA2717 amplifier, + 20 dB from the E4000 LNA and + 15 dB from the mixer.) The gain can be brought back down towards 20 dB if the gain of the E4000′s LNA and mixers are set at their minimum values – but lowering the gain seems counter-intuitive to casual users. Faced with a seemingly deaf receiver, their instinct will be to increase the gain of the E4000′s LNA to 30 dB, not to reduce it to -5dB!
There can be situations in which the uncontrolled gain of the BGA2717 alone is high enough to cause problems. In this case it may be helpful to put an attenuator in front of the FCD Pro. Other things being equal, overload problems get worse when a preamplifier is used in front of the FCD Pro. With another 20 dB of gain from a preamplifier, the total gain between the antenna and the mixer can be around 80 db. This corresponds to a voltage gain of around 10,000, which is much too high for a wideband system with puny little mixers.

In today’s world, exclusive messaging has developed into a vital component of communication. From trying to keep in contact with family to creating new relationships, individual text messaging has created it all much easier. Nevertheless, there is a popular misconception that personal text messaging is merely relevant to younger technology. This couldn’t be additional from the reality. In fact, private online messaging has become a means of communication for all ages. Together with the developments in technology as well as the increasing need for personal privacy, private message has grown to be a crucial part of our own daily lives. In the following paragraphs, we are going to go over exclusive messaging and the way it provides revolutionized conversation for all age brackets, from teens to seniors.
Young adults: Individual online messaging for your younger technology typically involves social media marketing programs such as WhatsApp, Instagram, and Snapchat. Nonetheless, with all the surge in cyberbullying and internet based harassment, exclusive text messaging has turned into a far more vital component of their communication. It possesses a risk-free and exclusive area where by they may communicate with their buddies and friends without anxiety about judgment or bullying. Moreover, private online messaging has additionally made it possible for such young adults to connect with individuals who share exactly the same interests and hobbies, that will create their very own individual residential areas.
Young Adults: As teens enter the staff, private text messaging has become a essential instrument for connection. It allows them to communicate with their peers and consumers while not having to uncover their individual cellular phone number or contact information. This allows them to conserve a operate-daily life balance, as they are able easily switch off from work information outside working time.
Mothers and fathers: Personal messaging has become a crucial instrument for moms and dads in which to stay contact with their young children. It provides a personal room where they may get in touch with their little ones without getting overheard by other individuals. This is especially important for moms and dads who wish to keep close track of their child’s on the internet activity, as individual online messaging gives a means of checking the chats without hovering over their shoulder.
Aging adults: Individual text messaging has also come to be connected to senior citizens, who might not be as tech-experienced as being the young technology. It gives a simple and reachable way of communication, specifically for many who may not have access to smartphones or any other gadgets. Additionally, it allows them to communicate with their loved ones without making their property, which can be particularly important during the COVID-19 pandemic.
Anyone: Private text messaging has revolutionized communication for everyone. It possesses a individual and safe place where by all age ranges can talk and connect to other people. It offers manufactured extended-length conversation achievable and has made it possible for us to remain in touch with this family and friends even when our company is kilometers aside. Private online messaging has offered a way of communication for individuals who may struggle to talk verbally, for example individuals with seeing and hearing or presentation impairments.
Private online messaging is becoming a crucial part of communication for those ages, from adolescents to elderly people. They have revolutionized the way you connect, supplying a secure and individual place in which we can easily connect with our family and create new areas. From social websites programs to function interaction, exclusive messaging has become a needed device for communication. When we consistently get accustomed to the shifting world, individual online messaging will always be a significant part of our daily lives.


With a Xiaomi router login produces computing life a lot more pleasant. Why confine yourself to focus on the computer system in the same place you took it right away? Installing a wireless router is simple and also makes it possible for you the flexibility to use the web, files, printers, and a lot more, from almost any location in your property or home. Before you shake your head about creating a wireless router on your to promote, trust me, in case I am capable of doing it, any individual can.
Here are a few very simple steps for implementing your wireless router.
Select the appropriate wireless router for the needs of yours.
In case you walk into the nearest Best Buy of yours or maybe some other computer store, you are going to see they have a multitude of routers available. You will find essentially (three) wireless network solutions available today; 802.11a, 802.11b, and 801.22g. So what would be the differences between these wireless solutions?
802.11a wireless protocol will be the oldest model of wireless networking technologies still available. While you might get 802.11a wireless hardware at prices that are affordable, I’d strongly encourage you to stay away from them. 802.11a is restricted in capacity and range versus 802.11b and 802.11g. So why set up the very first wireless network of yours with the oldest engineering.
802.11b wireless protocol (11Mbs) is definitely the most popular wireless technology in use today. In case you decide on this wireless process, you are going to be okay. But why not begin with the most recent and greatest wireless protocol still available?
802.11g is perfect wireless technology on the marketplace and all brand new pcs with built in wireless cards utilize this protocol. 802.11b wireless protocol was superseded by backward compatible 802.11g (54Mbs). What meaning is the fact that in case you have an 802.11b card on several of your computing systems, you are able to utilize an 802.11g wireless router without the requirement to change your wireless card. In case you have the choice, I’d really recommend buying 802.11g cards for the pcs of yours also to get the highest benefits of this wireless system technology.

Wi-Fi 6 testing support in CDRouter is available now
Portsmouth, N.H., April 23, 2020/PRNewswire – QA Cafe, a leading provider of network test and analysis solutions for broadband access, home networks, consumer electronics and service providers, today announced the first fully comprehensive automated test platform for Wi-Fi 6 capable access devices. With the addition of 802.11ax support in its high performance, dedicated test appliance, CDRouter gives service providers and manufacturers increased confidence and faster time to market for their Wi-Fi 6 products and service offerings.
“Current world events have shown the critical importance of wireless technology in connecting people,” said Timothy Winters, Chief Technology Officer at QA Cafe. “While there are many solutions on the market for testing the physical layer, there hasn’t been a solution for comprehensive testing of full featured Wi-Fi 6 routers, gateways, and access points. We’re excited to help the industry bring quality 802.11ax products to market faster at a time when there is heavy competitive pressure to strengthen their positioning as advanced, robust and secure.”
The addition expands CDRouter’s ever-growing portfolio of thousands of expert designed test cases and network simulation capabilities. Developers and ISP network architects will be able to test their Wi-Fi 6 implementations for security, IPv6, TCP, user applications, management protocols, and more, in addition to scaling and multi-client performance using simulated Wi-Fi clients. Full automation and comprehensive coverage of this testing dramatically increases product quality and saves valuable time and effort for developers.
“Wi-Fi routers and APs are more complex than ever before,” said Matt Langlois, Director of Engineering at QA Cafe. “Their quality is critical in both home and enterprise environments, especially when the number of Wi-Fi connections demanded by end-users has increased exponentially. They require many different protocols and technologies to work well and work together. Ad-hoc manual testing is not sustainable and can no longer ensure all the pieces work together as a system. Industry standard automated testing is needed to make sure that happens.”


Besides well-thought-out minimal kernel configuration, as with most embedded Linux projects the key to getting everything to fit is to link userspace applications with uClibc and to use busybox to stand in for any applications of which it is capable. cramfs makes it possible to fit everything in the memory.
What makes OpenAP even more interesting is the ability to use it in a meshing setup, with either bridging (802.1d Spanning Tree Protocol) or routing on AP-to-AP links. This in turn is enabled by the WDS (AP-to-AP linking) capability of the Host AP driver for Intersil Prism based 802.11b cards. This kind of meshing capability is currently found on no consumer 802.11 equipment.
Original work on OpenAP was done at instant802.com but since then various developers have continued in different directions. Local work on OpenAP is found at http://tools.collegeterrace.net/openap-ct/.


The PCB 8110 is used for function decoders, specially designed for switching the lighting in rolling stock by means of a relay via current carrying couplers. The PCB is equipped with a 21 pin MTC socket. All important signals are routed to easily accessible, large solder pads.
The Aux1 output of the decoder switches the
relay, that itself switches the current to the couplers on an off. The line
used for this current is the main power coming from the pickup shoe, the relay
can handle a max. current of 1 A.
In order to protect the couplers against over current this line is protected by a resettable.
The PCB is built with a small foot print
of only 31 x 16 mm and is only 6 mm in height (without the decoder attached)
and therefor fits into most rolling stock without problems.
You may use any function decoder with a 21MTC interface, such as ESU (54621) or Zimo (MX689).
The PCB is
usually placed in the first carriage, e.g. the driving trailer. The white front
lights and red taillights can be connected directly to the PCB. No additional
resistors are required when using LED, as the PCB is already fitted with
All following carriages are then connected via single-pole current carrying couplers.
These carriages need a pickup on the wheels as the second connection for the lighting.
The lighting modules user should be able to handle AC (e.g. digital current from the tracks).

In recent project, I was assigned a task to bring up Wi-Fi and Bluetooth. We used WL1835MOD combo module from TI to implement these two wireless features. After porting kernel drivers and application software, I found both features were malfunctioning. So I started checking the hardware.
Here’s the WLAN power-up sequence from WL1835MOD datasheet:
I probed the pads in the same order showing on the power-up sequence.
VBAT looked good and
EXT_32K) was a perfect 32KHz slow clock. But
WLAN_EN) seemed abnormal.
On WL1835MOD datasheet, voltage level of both
BT_EN should be 1.8V:
WLAN_EN pin was controlled by kernel driver, for the sake of convenience of debugging, I exported
WLAN_EN pin as an independent GPIO and toggled it between low and high, and found the voltage level was only 0.9V when set as high. So I checked the schematics along the circuit path of
WLAN_EN from WL1835MOD to host CPU and found this part:
The voltage level before
WIFI_EN_1V8 from host CPU) was 1.8V, but after
R89 (at test point
TP18) was only 0.9V. Same behavior was observed for
It’s a bit weird that there’s a voltage divider here. After consulting hardware engineer, I got the answer. On our previous product, the input voltage level was 3.3V, so we used a voltage divider to lower the voltage to 1.8V for
BT_EN. On this new product, the voltage level from host CPU is already 1.8V, so we don’t need this voltage divider any more, but hardware engineer forgot to remove it.
R89 with direct connection, Wi-Fi worked properly, but Bluetooth didn’t. But that’s another topic. I’ll describe it in a new post.
Hardware engineer will remove the voltage divider in next build.


Cisco Identity Services Engine (ISE) Quick Overview
Cisco Identity Services Engine (ISE) is a network administration product that enables the creation and enforcement of security and access policies for endpoint devices connected to the company’s routers and switches. The purpose is to simplify identity management across diverse devices and applications. In this short article we will be giving you an overview of the Cisco Identity Services Engine (ISE), that can help you to better grasp the major underlying details.
Cisco describes ISE as :
“The Cisco Identity Services Engine (ISE) offers a network-based approach for adaptable, trusted access everywhere, based on context. It gives you intelligent, integrated protection through intent-based policy and compliance solutions.”
Cisco ISE, What it is used for?
Cisco Identity Services Engine (ISE) is a server based product. By using the ISE you can either have a Cisco ISE appliance or Virtual Machine that enables the creation and enforcement of access polices for endpoint devices connected to a companies network. In simple words ISE is a network administration product that helps network administrators to create and enforce security and access policies for end point devices that are connected with the switch or router in company’s network.
What can be done with Cisco ISE?
As a network administrator that question arises when you see the ISE product suite. In a very layman terms user can control who can access your network and when they do what they can get access to or have what type of access rights configured for them. Cisco ISE can authenticate wired, wireless and vpn users. In terms of scalability it can scale to millions of endpoints. Based on many factors including the validity of a certificate, mac address or device profiling network administrator can swiftly identify a machine and determine which vlan that machine is placed into. Any devices that do not pass authorization checks will be placed into a guest vlan or simply denied access to the network. Nothing is completed with out proper logging and in Cisco ISE all information is logged and network administrator can instantly get a view of what is connected to companies network at any time.
Cisco ISE Nodes
The Cisco ISE solution is comprised of a deployment of nodes with following ISE variants:
- Policy Administration Node (PAN)
- Monitoring Node (MnT)
- Policy Services Node (PSN)
Depending on the size of network deployment all three variants can be run on the same device or spread across multiple devices for redundancy and scalability. We will briefly take a look at each one of them.
Policy Administration Node (PAN)
The Policy Administration Node is ISE Node at which the administrator logs into to configure policies and make changes to the entire ISE system. Once configured on the PAN the changes are pushed out to the policy services nodes. It handles all system related configurations and can be configured as standalone, primary or secondary.
Monitoring Node (MnT)
The Monitoring Node is where all the logs are collected and where report generation occurs. Every event that occurs within the ISE topology is logged to the monitoring node you can then generate reports showing the current status of connected devices and unknown devices on your network.
Policy Services Node(PSN)
The Policy Services Node is the contact point into the Company’s network. Each Network switch is configured to query a radius server to get the policy decision to apply to the network port the radius server is the PSN. In larger deployments you use multiple PSN’s to spread the load of all the network requests, thus effectively performing load balancing. The PSN provides network access, posture, guest access, client provisioning, and profiling services. There must be at least one PSN in a distributed setup.
The pxGrid framework is used to exchange context-sensitive information from the CISCO ISE session directory. It allows the ISE system to pass data to other Cisco platforms and third party vendors. This information can then be used to invoke actions to quarantine users or block access in response to network security events.

Cisco ISE Licensing
In a very simple manner, the license model of Cisco ISE is written below but all the information from Cisco can be found here in the admin guide license section.
The Cisco ISE licensing model allows user to purchase license based on enterprise needs and requirements. There are two ways of employing licenses. Traditional or Smart.
- Traditional licensing is where user import a license onto the appliance
- Smart licensing is where user manage a cisco account that holds all the information on the license purchased for your deployment.
Licenses are counted against concurrent, active sessions. An active session is one for which a RADIUS Accounting Start is received but RADIUS Accounting Stop has not yet been received.
The valid license options are as follows:
- ISE Base only
- ISE Base and Plus
- ISE Base and Apex
- ISE Base, Plus, and Apex
- ISE Base, Plus, Apex and AnyConnect Apex
The base license is a perpetual license and is the only requirement for AAA and IEEE802.1x and also covers guest services and Trustsec. A base license is consumed for every active device on the network.
ISE Base and Plus
A plus license is required for Bring Your Own Device (BYOD), Profiling, Adaptive Network Control (ANC) and PxGrid. A base license is required to install the plus license and the plus license is a subscription for 1,3 or 5 years.
ISE Base and Apex
The Apex license is the same as the plus license in that it is a 1,3,5 year subscription, requires the base license but is used for Third Party Mobile Device Management & Posture Compliance.
ISE Device Administration
There is a device administration license required for TACACS which is a perpetual license, a base license is required to install the device administration license and you only require one license per deployment.
An evaluation license covers 100 nodes and provide full Cisco ISE functionality for 90 days. All Cisco ISE appliances are supplied with an evaluation license.
Difference between Cisco ISE and ACS
The differences between ISE and ACS is the major question that arises in the minds of network managers. In simple terms ISE is the next generation of network authentication and is so much more powerful than ACS. ACS is used to authenticate users to network devices and for VPN sessions but it is not a NAC solution. If you want to implement full network access control you need Cisco ISE.
You can have the further information regarding Cisco ISE at following Cisco Website.

The Infrastructure Support feature allows you to configure a Mobi Pro card to transfer wirelessly over a home or studio Wi-Fi network instead of generating its own wireless network for transfers. With a configured network, your Mobi Pro card can transfer directly to a smartphone, tablet, or computer without disrupting those devices' wireless connections.
Please be aware of the following limitations for Infrastructure Support:
- A Mobi Pro card can store settings for up to 32 networks
- Infrastructure Support only works for configured networks that are in-range; when no configured networks are in-range, your Mobi Pro card will use its default method of directly connecting to your devices
- While you can configure any number of Mobi Pro cards to transfer over a home or studio Wi-Fi network, Eyefi Mobi apps can only connect to one card at a time for wireless transfers
Note: Depending on your mobile device, if you have enabled Infrastructure Support your Mobi Pro card will no longer appear to your phone or tablet as an available wireless network. To wirelessly transfer photos to your mobile devices again, you will need to disable Infrastructure Support in the Eyefi Mobi Desktop app's Advanced Settings (on Windows) or Preferences (on Mac).
To enable or disable Infrastructure Support, please see the following articles:
Can Mobi Pro use Infrastructure Support to transfer to devices that are not on the same wireless network?
No. In order for Infrastructure Support to transfer photos to a device, it must be configured to use the same network as your Mobi Pro card.
However, if you're an Eyefi Cloud member, you can transfer photos from a Mobi Pro card to your mobile device or computer and then upload those photos to Eyefi Cloud. After that, you can use Eyefi apps to sync any device on any network with Eyefi Cloud to view your photos.
For more details, please see How to Save Photos to Your Computer from Your Phone, Tablet, or Eyefi Cloud

As it happened, the earthquake at magnitude 7.7 MMI, which was later corrected by the Indonesian Meteorology and Geysical Agency, has occurred on Friday September 28 at 17:02 Local Time (11:02 am UTC), which also caused tsunami waves and hit Donggala and Palu.
Electricity, Cellular and all communication facilities at the location are cut off.
From the Luwuk Disaster Management Agency located 700 km from the epicenter of the Earthquake, we began communicating with YD8MII and YC8OBM, which informed that landslides occurred in the land lane and all communication access was cut off.
The Orari Center immediately establishes Emergency Freitas for Palu earthquakes at 7,110 MHz and activates the Lapan-Orari IO-86 satellite as a back up.
Many photos and videos circulating on social media, show the enormity of the earthquake.
From last night we waited to be able to communicate with YB8NT and YB8PR in Palu, using a mobile station.
At this time for the emergency station YB8NT communicates at 7,065 MHz due to the propagation factor at 7.110 MHz which is full of QRM.
With this email, we request all networks on IARU R3, for Orari to use emergency frequency at 7.110 MHz and 7.065 MHz to keep clear.
This earthquake is could be worst than in Lombok in the end of last August.
We will keep update.
lets keep up a good works

FIX8Group, a leader in pioneering event technical design and delivery, worked alongside Renault Sport Racing (RSR) to conceive and integrate a seamless, interactive, multi-purpose visual display for the Formula One (F1) team’s high-profile, pit lane touring garage.
Providing an important visual information highway for both RSR’s race team, their VIP visitors and RSR sponsors, the 40K wide, digital display canvas features enhanced interactive connectivity that enables the RSR team members, VIPs and Renault Sport Formula One Team sponsors to respond to race critical content, live, as it happens, while interacting with screen resolution native content, IP streamed content, trending social media threads and sponsor marketing messages in real time, via advanced touch screen technology. Crucially, the content can also be viewed from the pit lane and can be seen by the TV broadcast cameras, further maximising the all-important ROI for the Renault team and its sponsor messaging.
François Puentes, Head of Marketing Services for Renault Sport Racing states: “Transforming our guests’ experience whilst improving the Race Team’s work conditions in the garage were two key elements that FIX8Group helped deliver. Crucially, FIX8Group have been nothing but remarkable from the initial briefing to project completion. They have demonstrated high levels of creativity combined with the flexibility required by our industry.”
“The Renault team were looking for a multi-purpose installation that could be further developed over future seasons,” comments Neil Trenell, managing director of FIX8Group. “Our team was tasked with both the design and specification of a system that could display all the information the race team required alongside the sponsor marketing messages, social media feeds and news channels the VIPs would find interesting. In addition, VIP visitors can observe the race team in action and control and interact with what they see via intuitive touch screen technology.”
FIX8Group’s dedicated team of digital specialists designed custom HTML touch interfaces to provide connectivity for a number of components of the display and which are accessible at various levels to the Renault race team and their VIP audience. Individual digital players connect directly to each 4K screen and are synchronised via the network to provide a seamless playback of content across the whole 40K pixel canvas.
Although technically sophisticated, the end user interface is designed to be intuitive, requiring little or no instruction to access. In addition, the portable and robustly designed system has been created to meet the technical rigors of RSR’s global touring schedule and to be simple to install at each race site.
Paul Williams, technical director for FIX8Group concludes: “The system was integrated and tested in RSR’s UK factory in Enstone in June 2017 and debuted at the Silverstone GP with no issues. We continued to provide onsite support for an additional three races, however, for the remainder of the season. The marketing and race teams were able to run the system backed up by remote support from the FIX8Group team.”

Imagine you are fishing in the middle of the sea with your boat all alone. Suddenly you realize the boat is drifting in a different direction due to malfunction. You can’t possibly control it with the steering or other method. What do you do? Cry out loud like Tom Hanks in Cast Away with no possible rescue? If you know how to use a marine radio, you may get help from other boats.
Nope. You pick up your VHF marine radio, communicate with nearby boats or Coast Guards, and send messages for immediate help. This will save your life like magic! This is the very reason most boats have a built-in VHF radio station, and those that don’t have the boaters carry a mobile one.
In this piece, we will be looking at the ins and outs of a Very High-Frequency Marine Radio. You also Know the 9 fundamental topic of VHF marine radio.
Why VHF radio important in a boat?
VHF marine radio is an international radio communication among ships and vessels in the marine zone using high-frequency FM radio transmission. The frequency ranges from 156 to 174 MH.
You will not find the mobile network working on your boat once you leave the shore. So, in the middle of the sea, you are literally in the middle of nowhere with no communication to anybody.
So, to make sure there is help when you are in any kind of danger or in need of any help, the VHF radio is there. It will communicate with other boats around or the Coast Guards to save you from any type of trouble.
9 fundamental topic of VHF marine radio
If you have any queries about how to use a marine radio (VHF)? Here are the 9 most fundamental topics that any boaters should know. We discuss all the topics in detail. Keep with us.
- VHF radio Channels
- VHF radio Antennas
- Protocol and Etiquette
- Emergency Procedure
- Radio Protocol and Etiquette
- Operating procedures
Licensing: VHF radio Licence really necessary
This is the big question that most newbie boaters get tangled in their minds. Do I need a license to use a VHF radio on my boat? Well, if you have been worried about this, rest assured.
To your utter relief, you do not need a license to use a VHF radio on your boat. However, this applies to you if you are a recreational boater who is moving the boat within US territory. Otherwise, you may need to contact the authority to check for your permission.
VHF radio Channels: Which Channels Should I Use?
You need to know the VHF radio channels before you know how to use Marine Radio. The latest-model VHF radios have up to 25 channels. There are also International and Canadian channels, aside from the U.S. channels. Keep in mind;all channel are not for you to listen to.
You probably know the Channel 16 is the most important on your VHF radio. We will provide all the VHF radio channels below.
Keep with us.
Channel 06: This channel is reserved for safety messages and operations.
Channel 9: This is the most basic and primary channel. You need to switch to a working channel after you get connected to the primary channel.
Channel 16: It’s the channel for emergency and distress situations.
Channel 22A: This channel is used to establish contact with USCG only.
Channel 13: This one is used for establishing contact between vessels on a bridge to bridge level. You can request an opening for the bridge by using the channel. Any ship that comes with a length of no more than 64 feet can receive the message of this channel in the US territory.
This channel comes in real handy when it is very difficult to see due to fog and other reasons. You can easily communicate with freighters, ferries, and other ships.
Channel 68, 69, 71-71, 78A: These are known as working channels. These can be used by vessels that are non-commercial in nature, and you can establish ship-to-shore and ship-to-ship contact through these channels.
Channel 70: this channel is reserved for DSC safety calls.
VHF radio Antennas: The most important factor
This is really interesting. To find out the range of the antenna you have set on your boat, you need to go through a bit of calculation. First, you have to measure the height of the antenna from the water.
For example, suppose you have a 4-feet antenna set up on your boat, which is 5 feet above the water. So the total height is 9 feet.
Now, take out the square root of 9. It’s 3. Multiply it by 1.42. It’s a constant number to find out the range in millage. So, the result will be 12.78 miles.
Communications: How to communications witha VHF Radio
This is how you establish a VHF radio communication.
- Switch the VHF radio on and turn the knob to adjust the squelch
- Tune to the channel that the USCG monitors - channel 16
- You need to perform a radio check to make sure that the device is working correctly. Use an open channel other than channel 16 to conduct this test.
- Set the power setting of the radio to one watt. Then key the speaker.
- Call 3 times for the radio check. Then use the name of your boat and your exact location.
- See if anyone is replying to your communication. Wait for a few moments.
- For regular communication, you should always use channel 16
You may need to memorize the following jargon for proper communication.
- Over: It means you have finished talking and expecting a reply.
- Over and Out: This means you have terminated your transmission and don’t expect a reply. Roger: This means “I understand.”
- Wilco: This means “will comply.”
- Affirmative/Negative: This simply means YES/NO.
- Say Again: You need to use this if you need a repeat from the other party.
- I Spell: Say it before you are spelling a word.
- Figures: Say it before telling a number.
Course: How VHF Radio Course is Necessary?
If you are not well-equipped with the VHF radio you have, you can always go for the VHF Radio SRC Course. To enroll, you need to be at least 16 years old.
The exam will last for10 hours. You will be get a certificate upon successful completion of the exam.
What is digital selective calling (DSC)
Digital Selective Calling or DSC is an option on all fixed marine radio. The purpose of the system is to send your location information to the Coast Guard in case of an emergency.
It will send the GPS location of your place to ensure your safety. However, the radio device has to have a GPS installed in it.
Emergency procedure words
In an emergency situation, there are a few procedures to follow using a VHF radio. There are three phrases that are commonly used to send signals and messages.
Mayday: It’s the top-most urgent message. This will mean that the boat is in serious life-threatening danger.
Pan-Pan: This one is used for a danger that is sure to encounter within some time. It’s not immediately life-threatening, but if no help is there, it will drift towards a threat.
Securite: This is a safety keyword. It is sent to ensure that your location is safe.
Protocol and Etiquette: Know Your VHF Radio Protocol & Etiquette
The primary radio communication etiquette is as follows.
- The international language is English.
- You can’t speak and listen at the same time.
- Don’t interrupt the speaker.
- Don’t answer if the signal is not for you.
- Never transmit confidential, sensitive military or any other national security information.
- Regularly perform radio check.
- Check battery-charge.
- Keep volume high.
- Memorize the signs and language.
- Make the conversation short but precise.
- If you need to communicate with long sentences, divide the sentence into shorter sentences.
- Do not use abbreviations.
Operating procedures: How to use a marine radio
Here’s a standard process for operating a VHF radio.
- Call the destination station.
- Repeat the destination station name three times.
- Say ‘This Is’ once.
- Say the name of your vessel once.
- Then say ‘Over’.
- Wait for the other person to answer.
- After the response, suggest a specific channel to continue the conversation
- Then say ‘Over’.
- Wait for the response and listen.
- When done speaking, add ‘Out’ after ‘Over’ and terminate the communication.
Using a VHF marine radio is not at all tough. All you need to do is go through a few checks to ensure the device is working perfectly and you are able to use it easily. Then again, try to memorize the jargons that are used to send messages. In this article we have try to pic all information about How to use a marine radio.
It will make things way easier for you. First, however, try to have a VHF marine radio with you for the most effective communication. A malfunctioning radio device is the last thing you need at a time of danger.
