Hi all, I guess this could be a bigger problem over the west side of the
Pond. I saw an FSK signal appear weakly last night at about 2230z, but later
when I decided to switch on the logger, I realised it seemed to have gone
off. Then I saw that there was a wide hump of noise centred on 137 and
assume they switched to GMSK. This has a wider band width than FSK and was
showing at + / - 150Hz even over here. From my previous measurements it
seems to give similar reading but one does need to get is all in the RX
bandwidth.

I hope the noise is not too wide on that side, and am sorry to see the FCC
refusal after all this time.

Cheers de Alan G3NYK
