Dear John et al, LF Group,
135.8kHz isn't great - the bottom edge of the band has a lot of sideband noise from the Lakihegy HGA22 transmitter, plus the FSK signal from SXV close to this frequency is strong after dark in the UK. I would suggest moving up the band to 136.3kHz or above.
You can get a good view of the whole band in Europe from DF6NM's grabber at: http://www.alice-dsl.net/df6nm/grabber/Grabber.htm 

Good luck with the tests,

Cheers, Jim Moritz

If all goes well we shall in the next few days start tests with about 30W to a modest antenna in central Burgundy. We intend to use 135.8 unless someone suggests a better part of the band.
