hello guys yesterday i was broadcasting on the 76 mtr band
with around the 500 watts of power , the propagation was realy good
there were lots of reports from europe

today i got a email from a man from the uk with serious info
here is a copy of that mail


Hi Rinus

Thanks for the reply.

Yes, new listener, but not for the right reasons. :-)

I was listening to 'Plymouth Air Safety' on ssb, 3924 last night when
your carrier came up. 'Plymouth Air Safety' is a aeronautical traffic
separation unit run by the Royal Air Force for aircraft in the Plymouth
area on exercise.

Much as I love your transmissions, I feel that maybe you might want to
move away from this important frequency for safety reasons.

Your 6300 frequency is very close to Norway Navy frequency link on
6298.5khz too although 6305 seems clear of any important traffic.


I mention this because if I heard your S9 plus transmissions affecting
safety frequencies, you can be sure that the military were having the
same problem!

Keep yourself and others safe :-)


so radio operators watch out where you put your transmitter down
this time i got a email , next time who knows

Great post!

That's something all us free broadcasters should do is check the allocations for your ITU for safety frequencies (and other air traffic control) and always give a wide berth.

Usually these allocations are available as a free download from your contries government communications department.

Well generally they are there ignoring ITU regs and doing what that feel like.
The Uk got fined every year by the EU during the 1980s for allowing the emergency services to transmit in the band 2 broadcast band but it didn't stop the UK from prosecuting pirates for causing interference to the same emergency services! Even though they shouldn't have been there under European law!
Oh by the way when the pirates argued this they still lost their case!!
The law is a ass.

We can confirm that (within the United Kingdom anyway) the frequency range 3900kHz to 3950kHz is for 'Government Use' (fixed aero-nautical mobile).

It should also be noted that 6268kHz and 6312kHz are used for International distress operations (CQD, SOS, etc), so it might be an idea to try and avoid using frequencies +/- 10kHz of these.
