New UK Amateur Radio 146 MHz Allocation

New Ways of Amateur CommunicationsThe RSGB VHF Manager John Regnault G4SWX gave a key presentation to the RSGB Convention on October 12 about the new amateur radio allocation at 146 MHz.

John said the future use of this band is very much in our hands. If we merely use it for more-of-the-same (conventional modulation and uses) then future use will not be viewed very favourably.

He suggested we should use the band imaginatively, with digital modes and/or new services that would not sit easily within the existing band. Digital ATV with 500 kHz bandwidth, Digital Voice, Spread Spectrum, Data Services along with things not yet widely thought of are the type of activity that is desired.

Developers of wideband modes may face challenges in ensuring their emissions are contained within the new band. Some wideband modes currently used on 1240 MHz have sidebands just 30 dB down that extend over a wide range, this would not be acceptable on 146 MHz.

Bandwidth tailoring will be imperative to ensure no RF extends into the weak signal satellite segment at 145.8-146.0 MHz (the Lunar 4M JT65B beacon uses 145.980 MHz). Narrow band users on 147 MHz must also be protected from any increase in the noise floor.

John asked that those trying new things on the band should report the work they do even if the experiment is a failure. His contact email address is vhf.manager<at>rsgb.org.uk

It may even be that successful exploitation of the new band could lead to further release to amateurs of much needed VHF spectrum!

The new allocation has both Geographical and ERP restrictions. The Ofcom statement on the allocation can be seen at http://stakeholders.ofcom.org.uk/binaries/consultations/vhf-143-169mhz/statement/VHF_Release_statement.pdf

At the end of October Full licence holders will be able to obtain an NoV for 146  MHz operation from the RSGB online NoV page at http://rsgb.org/main/operating/licensing-novs-visitors/online-nov-application/

Amateur Radio Licence Review

The Radio Society of Great Britain General Manager, Graham Coomber G0NBI, has issued this statement on the Ofcom amateur radio licence review.

We held our regular meeting with Ofcom last Thursday and, as you will know, Ofcom attended the Convention at the weekend. Feedback from those events is that

• Only 300 or so people have responded to the consultation document so far.
• Ofcom will be relying heavily on the volume and content of the responses as evidence of what the amateur radio community feels about the proposals.

Whilst we published some explanatory notes on the website soon after the document was released, it is apparent that many amateurs have not yet read the document which is far from straightforward in several places.

We are thus today publishing further guidance together with suggested responses to the key questions www.rsgb.org/ocguidance

There is now just one week before Ofcom’s consultation period ends (20th October) and thus time is of the essence. This note is to ask for your personal support as follows.

Please make sure that you respond to Ofcom.

Please make contact with your club chair (if you belong to a club) or any other amateurs that you are in contact with and urge them to do the same.

Many thanks,

Graham Coomber, G0NBI

4M Lunar Payload in Practical Wireless Magazine

Cover November 2014.inddThe November issue of Practical Wireless (PW) magazine, in the shops now, devotes three pages to the 4M amateur radio lunar payload which will transmit JT65B on 145.980 MHz. Beijing plan to launch the payload on October 23. The article, written by Colin Redwood G6MXL, is well worth reading.

PW magazine also carries the popular columns World of VHF by Tim Kirby G4VXE, Data Modes by Mike Richards G4WNC and Emerging Technology by Chris Lorek G4HCL.

The Southend Echo reports on the contact between pupils at Winter Gardens Primary School in Canvey, Essex and the International Space Station.

The contact took place on October 8 having taken two years of preparation. It was organised by the South Essex Amateur Radio Society and involved a link-up with an amateur radio station in California, W6SRJ, who relayed the signal to and from the ISS while it was traveling over the USA at 27,600 km/h. The children were able to speak to astronaut Reid Wiseman KF5LKT who was using the ISS callsign NA1SS.

The newspaper article includes a picture of the school pupils with Pete sipple M0PSX, read it at

The Roy Stevens, G2BVN, Trophy awarded to Gaston, ON4WF

Gaston Bertels ON4WF - ARISS Contact

The IARU Region 1 Roy Stevens, G2BVN, Memorial Trophy was awarded to Gaston Bertels, ON4WF, for his meritorious service to amateur radio over many years. Gaston was the chairman of the Eurocom Working Group and then the chairman of the ARSPEX Working Group. Gaston, aged 87, has decided to step down as ARSPEX WG chairman.

Gaston received a standing ovation when the award was announced.

AMSAT-UK add their congratulations and respect for all his hard work in IARU Region 1 and with the organisation of the ARISS School contacts, as well as his Chairmanship of ARISS-EU and, for a time, of ARISS-International.

Gaston was instrumental in getting DATV antennas for 1260 and 2400 MHz installed on the International Space Station (ISS), see http://www.southgatearc.org/news/march2007/ariss_antenna_donations.htm

6th European CubeSat Symposium

Swiss Space Systems S3

Swiss Space Systems S3

The 6th European CubeSat Symposium will take place from October 14-16, 2014 at Estavayer-le-Lac in Switzerland.

The Symposium has attracted more than 100 abstracts submitted from 31 different countries. Von Karman Institute and Swiss Space Systems are proud to support the CubeSat community by coorganising this leading CubeSat event in Europe, for the first time in Switzerland.

Von Karman Institute continues to act as the coordinator of the World’s most ambitious CubeSat Project QB50, whereas Swiss Space Systems is designing an innovative launcher specifically for small satellites to bring the launch costs to 25% of today’s market value.

The symposium abstracts are available at
