Dear Dave, LF Group,
The problem with this part of the band is that it gets very severe QRM from SXV and the sidebands of HGA22, making it fairly useless for weak-signal reception in Europe. Last winter, a number of stations including M0BMU used frequencies centered on 137.5kHz for WSPR, which worked quite well since this is also reasonably well spaced from DCF39's sidebands - it is even in the "digital modes" part of the band plan! 

Cheers, Jim Moritz
73 de M0BMU

I guess we have to decide whether to go for the top or bottom of the band, I 
know some areas have problems with strong adjacent channel stuff. Would
135.85 be a good start? (I guess that's well out of Mal's way!)
