Have a look at Rik's site for lots of aerial information
http://www.qsl.net/on7yd/136khz.htm
There is also some info and the latest news on my site
http://www.wireless.org.uk/

Saturday and Sunday are the best days but at this time of year the band gets
noisy with static after mid-day. If you want a test any evening I can
radiate a signal for you.
As there isn't much traffic these days you'll probably get away with the CW
filter in the B40. I normally listen in 100Hz bandwidth during QSOs but I
listen to the whole band in SSB bandwidth when I'm in the shack, then I can
hear if anyone pops up and home in on them with the narrow filter.

The big signal on 138.8 is from Germany and should be about 30dB above your
noise floor (in CW bandwidth) if you are going to hear amateur signals.

Good Luck.
