I monitored the 137kHz 'mistery signal' last night :
1. Although it sounds RTTY-like I cannot see any mark /space lines with GRAM
2. It came out of the noise arround 21.30UT and built up (with some QSB
periods) until 23.00UT (when I went to bed). I left the ON5OO software
running all night (from 22UT until 08UT) the signal was still there (and
loud) at that time.
I will have a look at the data from the ON5OO software tonight.
