Some nice signals overnight,

This time, VO1NA with 10uW ERP has the winning signal!

Perhaps we can improve on the record of 25 chars T/A
with the signal from Dex continuing at good S/N until
nearly midday?

S/N for decoding is generally better than appears from
the spectrogram - best S/N is found at around 320 to 340
degrees, steering away from the noise, but the SG doesn't
show that because of the bearing filtering.

I'll do some measurements on the overnight recordings to
see what max message it might be able to do.
