These are some RTTY (Baudot) stations heard in the southwest UK since 2003 December and successfully decoded. They're all marine weather bulletins unless otherwise noted. If they're not transmitting real data they often send an idler signal. The reports use a variety of formats, some of which can look a little cryptic, but when they use plain text, the French stations are mostly in French, and the German stations (Deutscher Wetterdienst) are in German and English.
I haven't noted which are "normal" and which are "reverse" shift because different programs treat them different ways around and I don't have a known standard to settle the ambiguity satisfactorily.
There are a lot of other FSK signals around which are not decodable; apparently some simply use Cyrillic or Polish character sets, but without additional decoding software it's impossible to tell which.
The frequencies given are measured centre carrier frequencies; to tune these, set your receiver to 1.7kHz below the listed frequency, in USB mode.
