Just to thank you for that nice report on my 3600kHz transmission.
Considering the appalling lightning static, peaking here regularly at
was amazed at how well the signal was received by stations all over the UK.
I moved to 1840kHz to listen to the MT63 1kHz broadcast from GX0BAA,
and received about 75% through the even more terrible lightning static on
The difference in the wanted MT63 signal and the unwanted static was in
excess of 60dB!
Regarding 5279kHz, I am not sure whether a transmission actually took place
but I will check this and report back. We are a bit thin on the ground for
transmitting stations and sometimes there are just not enough of us to go
around and it is often the 5279kHz that we have trouble covering. As you'll
appreciate, all sending is voluntary.
The GB2RS transmissions use 1kHz long interleave as standard and at least
'first time round' should be transmitted like this; if the sending station
repeat the news in 2kHz bandwidth then they are at liberty to do so
If you want to find out who is due to transmit the data GB2RS, you can go to
the web page I maintain at http://www.g4hpe.piczo.com/
which shows the
projected newsreading rota.
Out of interest to all MT63 enthusiasts like myself and Chris, I am also a
of the Raynet HF team that is assessing voice and data modes below 30MHz
for potential UK disaster coverage. We have done quite a lot of testing
PSK31 but there is no doubt that the superior error correction of MT63 shows
through, particularly in the sort of tricky conditions affecting the UK on
very thundery night.
