Re: LF: re 137.0 last night

Hi Alan,

this is how CFH looked here, before and after the change. Best "noise-to-noise" ratio during last night occured around 2:30 and was about 5dB.

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.
