Interesting trace Tim,
I can detect GB3MCB and, at the moment, can
even hear the CW ident. I'm also seeing doppler shifted signals from
Attached (I hope) is a screenshot taken using
SpectrumLabs a few moments ago.
As you will see, some direct and some
However, the thing I wanted to ask about is the
frequency you mentioned. Is that dial frequency, or the frequency of
the actual recieved signal? I see that your trace is at about 1kHz in,
so I guess that you are using USB to received the signal? In which
case, did you add the 1kHz audio offset to the dial reading?
Personally, I tend to monitor using CW with a
600Hz CW offset on the receiver and set the received signal to the 600Hz
point on the waterfall. The dial frequency at the moment is
1296.847.38MHz and I often see that I need to add about 1kHz to what other
people put out as the frequency that they hear the beacon on to what I need
to use in CW mode.

Just as another data point I can hear GB3MCB up here in IO83LR at sea
It is peaking to s3 this morning and quite audible.
I make it's freq 1296.846325MHz - GPS locked IC-9100 and using
Spectran to measure audio tone.
See attached file.
Using a 16 ele at about 30 feet AGL /ASL
As for 6 mtrs - MCB also seems a little off freq there as well, not
sure why as my IC-7800 is also GPS locked, maybe they use a master
