Ash Gohil and Paul Jarvis G8RMM at 2013 RSGB Convention

One of the highlights of the RSGB Convention, October 12-13, was a talk by Ofcom’s Paul Jarvis G8RMM and Ash Gohil about the upcoming Amateur Radio Licence Review.

Read the Essex Ham report at
http://www.essexham.co.uk/news/ofcom-amateur-radio-licence-review.html

The RSGB are planning to offer three further Litmus Tests shortly on:
– Licence Progression
– /AM usage for unattended airborne usage (balloons, etc)
– Remote Operation.

The new Discussion Forums will be available at http://rsgbdata.net/litmus/viewforum.php?f=9

Other issues that people may want to discuss that came from Ofcom’s presentation on Sunday, or at the National Hamfest, should be posted to the “Suggestions for New Topics” Litmus Test, see

QB50 satellites apply for frequency coordination

Typical QB50 CubeSatThe first CubeSats of the planned QB50 satellite constellation have applied to the IARU for frequency coordination.

QB50 has the scientific objective to study in situ the temporal and spatial variations of a number of key constituents and parameters in the lower thermosphere (90-320 km) with a network of about 40 double and 10 triple CubeSats. These, university built, CubeSats will be launched into a 320 km circular orbit, will be separated by a few hundred kilometres and carry identical science sensors.

The sensors will monitor parameters that will greatly increase our knowledge and understanding of this little explored region of the E and F layers of the Ionosphere. QB50 will also study the re-entry process by measuring a number of key parameters during re-entry and by comparing predicted and actual CubeSat trajectories and orbital lifetimes.

Some of the first CubeSats to apply for frequency coordination are SUSat, Hoopoe/IL01, SAT-IP2, ExAlta-1, OGMS-SA, InflateSail, XCubesat, SpaceCube, UNSA-SAT1, EntrySat, PHOENIX and Dragsat-CubeSat, see http://www.amsatuk.me.uk/iaru/formal.php

437.700 and 437.5966 MHz ham radio balloons heading for UK

SP3OSJ Pico Balloon

SP3OSJ Pico Balloon

Artur SP3OSJ has launched an amateur radio solar powered pico balloon on 437.700 MHz USB from Poland which should be over the UK on Sunday, October 13. Also on its way is another pico balloon SP3UOB on 437.5966 MHz USB.

The SP3OSJ balloon, launched at about 06:01 UT on Saturday morning, is on its way west from Poland with the predicted path going over Denmark then on to the United Kingdom.

Artur asks for other amateurs to assist by tracking the telemetry signal on approximately 437.700 MHz USB. It is running UKHAS RTTY 100 baud 7n2, 470 Hz shift – SP3OSJ (SP3OSJ/08 in dl-fldigi).

Tomasz also request amateurs to listen for his balloon on 437.5966 MHz USB.

The payload on the balloons weigh only a few tens of grams. They comprise a tiny 437 MHz transmitter running about 10 milliwatts and a GPS receiver. The SP3OSJ balloon is powered by a rechargeable battery and solar panel with should give an extended lifetime of several days.

SP3OSJ is flying at an altitude of between 3000 and 3500 metres and should have a radio range of around 150 km.

Real-time tracking of this and other balloons is available at http://spacenear.us/tracker/

Dave Johnson G4DPZ will be giving a presentation on the amateur radio AMSAT-UK FUNcube-1 and UK Space Agency (UKSA) UKube-1 satellites to the RSGB Convention on Saturday.

The presentation will take place from 16:45-17:30 in the Cook 2 room at Horwood House, MK17 0PH on Saturday, October 12.

FUNcube-1 carries a 435/145 linear transponder for SSB and CW communications and an educational telemetry beacon using 1k2 BPSK for school outreach purposes.

Ukube-1 carries a set of AMSAT-UK FUNcube boards that will provide an additional 435/145 MHz linear transponder and educational telemetry beacon.

UKHAS Arctic Challenge

James Coxon M6JCX brings news of the UK High Altitude Society Arctic Challenge.

This is a challenge open to launch a balloon/payload from the UK that crosses the Arctic Circle before the next UKHAS Conference in September 2014.

The challenge will require both development of a payload, launching a floating balloon but also the ability to receive the data confirming it has crossed the Arctic Circle.

There is a prize for the first person to complete this challenge, obviously eternal glory but also a trophy and a cash prize.

For more information see the wiki page
