The next episode of the UK's only TV show dedicated to all things radio, TX Factor, is released on the 17th of March. Go to for details. Factor is sponsored by the RSGB and Martin Lynch & Sons. In amongst the item on Episode 15, Bob discovers the fun to be had remotely controlling his Icom IC-7300 over the internet using Icom’s proprietary software interface and shows you how to set it up. The IC-7300 was reviewed in the August 2016 RadCom. Mike and Bob meet two youngsters who are passionate about amateur radio and find out how they are making more people, both young and old, aware of the delights of our hobby. TX Factor is available to stream to your phone, tablet, computer or smart TV.

With the significant increase in numbers of 70cm digital voice repeaters that have inputs at the low end of the band, the ETCC have been reminded to highlight the power restrictions that apply to 430-432MHz. The maximum peak envelope power in this part of the band is 40W effective radiated power for Full and Intermediate Licensees and 10W ERP for Foundation licensees. Given that many modern mobiles can run 50W or more to high gain collinear aerials it is very easy to exceed these levels so please take care to keep your power to the minimum required and certainly never above the limits mandated in your licence.

The talk Being the DX, QRP by Dominic Baines, M1KTA is the latest 2016 RSGB Convention lecture available for members to view via the new video portal at It joins Contesting from VY2ZM on Prince Edward Island by Jeff Briggs, VY2ZM; Developments in IOTA, update on electronic QSLing and the future by Roger Ballister, G3KMA and Advances in amateur television by Noel Matthews, G8GTZ.

Following a request from the RSGB, Ofcom has kindly agreed an increased power level of 50 watts ERP for new 146-147MHz Notice of Variation applications. The band is only available to holders of a Full Licence and all other NoV terms remain unchanged, including antenna height and geographical restrictions. New applicants or existing NoV holders can use the online application system at to get the new NoV free of charge.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 10th of March

In the last report we said the ongoing disturbed geomagnetic conditions may have settled, with a predicted K index of two. Unfortunately, this didn't happen as early as expected and the beginning of the week saw a K index up as high as five. This had an adverse effect on maximum useable frequencies, with a very unsettled ionosphere. Daytime MUFs seldom allowed the bands much higher than 20 metres to be used. This was also not helped by an absence of sunspots.

The slightly better news is that on Thursday a look at the sun in extreme UV light showed there were no earth-facing coronal holes on the sun's equator, although there are some around its poles. This means that we can hope for a few days of lower K indices this weekend, and hopefully more settled HF conditions for the Commonwealth Contest.

NOAA predicts the solar flux index will be in the mid 70s next week. To put this in perspective, the solar flux index never gets below 65 at sunspot minimum, so conditions are not good. NOAA also predicts conditions may be geomagnetically unsettled again from mid week, with a potential maximum K index of five either Wednesday or Thursday. So look for better DX conditions at the beginning of the week, and then the potential for a pre-auroral opening on the upper bands just as the K index rises, although this is harder to predict.

And now the VHF and up propagation news

It looks like the early part of this week could bring some Tropo over the South and Central part of the UK, extending in to the North Sea up to Norway, so keep an eye on the bands and put out some CQ calls to generate interest. There is the possibility of VHF auroral activity mid week if the K index rises as predicted.

The winter minimum in meteor activity continues until the April Lyrids, so stick to the best time for random meteor scatter contacts, around dawn, when the earth is rotating into the flux of meteoric particles.

The Moon’s declination goes negative on Monday so Moon windows are shortening. The Moon is also heading out to apogee next Sunday so losses will be high and increasing as the week progresses.

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