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.

Feeling 136 would be fun I am seeking more enlightenment re: improving

antenna efficiency so saw ref. to this list and subscribed.

Also puzzled about selectivity in a band only 2 and a bit Khz wide.

I have an old B40 LF RX all perked up but  no 136 sigs heard yet .
Although it produced SAQ last week at 17.2 Khz and I have a big carrier at
138.8 with bursts of data-dribble ok. Is there a recognised 136 activity
time ? Is there a 136 net on 80 mtrs. did I hear. When and what freq.?

I imagine CW sigs from anywhere in the band  will be heard at once from

near

zero beat up to 2000 Hz.??

Am I missing something here?  (I spend a lot of time in W land so not up

to

date in LF activity in Europe )

Is there a recognised 136 activity time ?
