The news headlines:

A new easy-to-use amateur radio satellite was launched last weekend and was switched on for general use on Thursday. AO-91, also known as RadFxSat and Fox-1B is a Cubesat that carries an FM transponder. The uplink is on 435.250MHz FM, plus or minus Doppler, with a mandatory 67Hz CTCSS tone for access. The downlink is on 145.960MHz FM. The present position of the satellite can be seen and all amateurs are invited to listen out for the bird. The northernmost point of its orbit periodically passes roughly over Bedford, meaning that it will give good service over the whole of the British Isles, Europe, and beyond. Full details about the satellite are on the AMSAT-UK website at By coincidence, another AMSAT mission, FUNcube-1, also known as AO-73, celebrated its fourth birthday in space this week. It has travelled well over 500 million miles in orbit since launch and been received tens of thousands of times.

On the subject of birthdays, the International Telecommunications Union celebrated 90 years of ITU-Radiocommunications Study Groups on the 21st of November. A 90th anniversary celebration issue of the ITUNews magazine can be downloaded from Also, ITU HQ station 4U1ITU will be active in the CQ World Wide DX CW contest. QSL via operators’ instructions.

Sad news now. One of the pioneers of software defined radio, Dr Vanu Bose, died suddenly at the age of just 52 on the 11th of November. He gained his PhD at MIT, founded, and was CEO of Vanu, Inc. His company made much early progress in SDR, including developing the first SDR GSM mobile phone base station. Later developments included solar-powered mobile phone base stations. Dr Bose donated many of these to Puerto Rico this year to replace infrastructure destroyed by the hurricanes.

The recent RSGB VDSL Survey highlighted the growing problem with RF noise radiated from phone lines carrying VDSL2 broadband services. Backed by the RSGB Legacy Fund, members of the RSGB EMC Committee are researching and developing RF digital signal processing techniques to identify and, hopefully, help mitigate VDSL RFI. The first stage, which is currently underway, is analysing files recorded by amateurs around the country and submitted via the VDSL Survey. The team will report progress as it happens.

The RSGB Emerging Technology Coordination Committee, or ETCC, develops and enhances the UK amateur radio repeater and data communications systems, and promotes the introduction and rollout of appropriate new technologies. The Chair of the ETCC, John McCullagh, GI4BWM, has decided to retire from his role, after many years of invaluable service. RSGB is therefore seeking a volunteer, who must be an RSGB Member, to take over the position. The position of Chair of the ETCC Committee is offered for an initial period of up to three years. Anyone interested in this important role should, in the first instance, write to Steve Thomas, M1ACB, RSGB General Manager, via email to, providing details of their amateur radio and other relevant experience.

The RSGB telephone system suffered some problems this week. Some calls went unanswered and we may have lost some messages that were left. The RSGB apologises for anyone inconvenienced by these issues.

This weekend sandwiches between so-called Black Friday and Cyber Monday. These relatively new traditions see discounts from all kinds of sellers, including the RSGB Bookshop. If you are an RSGB Member and have kept the RSGB up to date with your email address, you will also have received an extra discount voucher. All RSGB Members are encouraged to visit from time to time to make sure all their details are up to date.

And now the DX news compiled from 425 DX News and other sources

This is another very good week for DX, with teams around the world activating unusual places for the CQ WW contest this weekend. Many are operating for several days before and after the contest, giving the opportunity for lots of interesting contacts. Keep an ear on the bands and your eye on the propagation tools – you might be surprised what you bag. There are far too many DXpeditions to list them all, but here is a small sample.

John, W2GD is on the air as P40W from Aruba, SA-036 until the 28th of November. Activity is on the HF bands. QSL direct to N2MM.

A group of operators will be on the air from Ghana as 9G5W until the 29th of November. Activity is on 160 to 10 metres using CW, SSB and RTTY. QSL via S59ZZ.

Oliver, F6ARC is active holiday-style as FG/F6ARC until the 29th of November from Guadeloupe, NA-201. He is on various HF bands, CW only. QSL via FE11DX.

UA4CC is on the air until the 30th of November from Montenegro as 4O7CC. Activity is on the HF bands using CW, SSB and various digital modes, including FT8. QSL to home call.

LU3YK, LU7VB, LU8YD and LU9VEA will be active as HC8LUT from San Cristobal Island, SA-004 from the 29th of November to the 8th of December. Activity will be on 160 to 10 metres using mainly SSB, but also PSK31, JT65, WSPR and FT8, plus satellite activity on FM and other modes. QSL via IK2DUW and LoTW, logsearch on Club Log.

Now the special event news

The main Special Event Station news is the start of the very special special event station GB17YOTA. This callsign will be aired by clubs up and down the country during the month of December. Sandringham School radio club starts the ball rolling on Friday the 1st of December, handing over to RSGB Region 7 Youth Committee representative Will Davies, 2W0WOD, on Saturday. Next Sunday sees the Wessex Contest Group taking up the call. A list of activations can be found on page 8 of the December RadCom.

Very few special event stations seem to be on the air this week. Ofcom reported that no UK special event stations gave their consent to be publicised in the month of November. When an application is made for a Special Event callsign the applicant signs a confirmation that the Special Event Station is in support of an event which is of special significance, and will be open to viewing by members of the public. So there is logic in ticking the box to permit Ofcom to tell RSGB about your event, so that we can publicise it in GB2RS, in RadCom, and on the RSGB website.

Now the contest news

This weekend sees the CQ Worldwide DX CW contest, which started at 0000 UTC on Saturday morning and runs to 2359UTC on Sunday night. This CW-only event uses all the contest bands from 1.8 to 28MHz. The exchange is RST plus CQ Zone, which for the UK is 14.

Tuesday sees the SHF UKAC from 2200 to 2230UTC. Using all modes on the 2.3GHz to 10GHz bands, signal report, serial number and locator forms the exchange.

On Wednesday it’s the UKEICC 80m contest from 2000 to 2100UTC. Using CW only on the 3.5MHz band, the exchange is your 4-character locator square.

On Thursday the Autumn Series continues from 1900 to 2030UTC on the 80m band, CW. The exchange is signal report plus serial number.

The UK Six Metre Group’s Winter Marathon kicks off on Friday, running until the end of December. Using all modes on the 50MHz band, the exchange is signal report plus locator.

Next weekend sees the ARRL 160m contest running from 2200UTC on Friday until 1600UTC on Sunday. Using CW only, the exchange is the usual signal report. US and Canadian stations also send their ARRL or RAC section number.

Finally for this week, the RSGB 144MHz AFS contest takes place next Sunday. Running from 1000 to 1600UTC on the 2m band and using all modes, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 24th of November.

The Solar Flux Index remained in the 70s last week, reflecting the continued absence of sunspots. Geomagnetic conditions were unsettled at the beginning of the week, but improved as the effects of a coronal hole passed. We were left with a mixed bag of HF propagation, with fair conditions at times and poorer ones at others.

Highlights were the J5T DXpedition to Guinea-Bissau, and the Polish TO2SP DXpedition to St Barthelemy, with many radio amateurs filling much-wanted band slots. Other DX stations were on the air from around the world as they prepared for this weekend’s CQ Worldwide CW contest. Speaking of which, conditions seem likely to be fairly settled on Saturday 25th, but another earth-facing coronal hole looks as though it could threaten the ionosphere on Sunday 26th.

Saturday might be the best day for working DX in CQ Worldwide, whereas Sunday may be a little more unpredictable. If our prediction is correct, and solar matter impacts the Earth, there is the possibility of an initial HF enhancement, but then declining maximum useable frequencies as the K index rises. Otherwise, expect 20 and 15 metres to be the main HF bands for DX, with good 10m openings being very thin on the ground.

Recently, some days have also seen some Sporadic-E responses on the ionosonde data, which can make a difference for local near vertical incidence skywave activity on 80m in the evening, when the foF2 ionisation is usually insufficient for inter-G nets. Since this may be related to jet stream activity, and there will be plenty of that this week, it’s certainly worth a check. You can monitor the ionosphere using the daily graphs available on

And now the VHF and up propagation news.

The charts in both the primary longer-range models seem to be locked into a low-pressure story for next week, which can mean quite windy and often colder weather too. There is little of cheer for the VHF/UHF bands in this pattern, except perhaps the odd bit of rain scatter as showers run down the coasts on northerly winds. Both models do suggest a build-up of higher pressure to the west of Ireland later next week and this may give some prospects for Tropo as we move into the following week. But otherwise it is looking like thin pickings for weather-related propagation this time.

However, we are now into the build-up to what is often one of the better meteor showers of the year. The Geminids has a broad peak, culminating on the 13th and 14th of December, but there are normally many meteors throughout the shower period giving useful reflections. Unlike many meteor showers the Geminids is associated with the asteroid 3200 Phaethon, rather than a comet.

Minor shower Puppid Velids also starts around the end of this weekly report, with a peak around the 9th of December. Moonlight may affect shower visual sightings, but will not affect radio reflections. Talking of moonlight, the moon is waxing gibbous this week with the half moon this evening, Sunday, and the full moon is next Sunday.

As we move into the latter half of the week the moon-path degradation is very low and better suited to smaller EME station operations. For those early birds, the morning moon will favour paths to the west, whilst the early and later evening moon will be better for paths to the east of the UK.

And that’s all from the propagation team this week.
