In South Africa the latest radio regulations permit the use by radio amateurs of 26dBW (400W) on a 10kHz wide band 40.675 – 40.685MHz “for propagation studies only”. Now this is exactly what OFCOM should have done in the interest of real radio-science research. Personally I think a wider band would be better, but how far sighted to allocate this at all. Well done S.Africa.
OK, I could pay £50 for a special research permit, but this is exactly what radio amateurs need for real self training and radio-science research. The take-up might be small, but real research would take place.
OFCOM/RSGB – how about it please? You have just allocated 2MHz (2 chunks of 1MHz) of spectrum that will be used by just a handful mainly for DTV tests. How about a much smaller slice somewhere really useful in the radio spectrum? 40MHz is mid-way between 10m and 6m, so ideal for Es tests and TEP tests over the equator.
Well, I had a letter today from an amateur in South Africa who I hear have been allocated a small band at 40MHz. There are already a couple of EU beacons around 40MHz (OZ and G).
It would be so good if OFCOM here in the UK saw the real value in even a very small, shared band around 40MHz. Instead, we get given chunks (1MHz at 2m and 1MHz at 4m) which will hardly get touched by most. Surely a small 100kHz shared band at 40MHz that would really be of value to radio science has merit?
Of course, allocating ad interim chunks of unused spectrum to the amateur service is a “no-brainer” for dear old OFCOM. Fine doing this, but there would have been far better options, but these would have needed brain engagement, so out of the question? I hope that the RSGB and OFCOM talk some more and add new bits of spectrum soon.
An amateur band at 40MHz would be really useful as I suspect the F2 MUF has been in this region several times in the last few years. There are a very few beacons around 40MHz (UK and Denmark only I believe) but wouldn’t it be good to have even 100kHz around this frequency? Sadly it is very unlikely, but I would happily lose 100kHz at the top of 10m in exchange. It would also be a very useful Es band.
Somehow I can’t see this happening, more is the pity. The world of radio science would really benefit. This would have been so much more useful than 146-147MHz recently released to UK amateurs by NoV. I know a handful of UK amateurs are trying narrowband DTV but the 2m band is mainly Japanese “black boxes” and is mostly white noise in most areas.
