Garry / John:
Thanks for the capture - I did not even notice the constant keying.......it appears to be fixed and I will
keep a sharper eye on it over the weekend.   Maybe a sticky relay keying the cathode of the 813's ?

Again, thanks to both for the report...... I plan to keep it  going through the Summer with the occasional
period for maintenance and antenna work for those checking r antennas, rcvrs and propagation- .

Perhaps Mitch has a keying problem.    Caught again !

> My session in the wee hours of Friday morning produced the same result on MP's frequency that Garry saw, except a bit weaker (though still evident to the ear) and more broken up by noise, until the pre-sunrise fade took both signal and static away from me.  I wonder from both what I saw and Garry's clearer version whether Mitch was sending some more esoteric mode than QRSS, as there are fluctuations in carrier level that may or may not correspond to the effects of noise.  Also, of course, a 30-sec Argo screen centered near the carrier of interest wouldn't show us any modulation sidebands for baud rates faster than about 1.5/second.

It spans just under one hour, ending at 1:37 AM CDT/0637 UTC, with relatively strong signal for up to 20 minutes at a time, and weaker for about 20 minutes between.  A similar pattern is evident douring the rest of the night's captures.  This was with Argo's visual gain set for "Lo" incidentally, as the carrier was harder to distinguish from the background during noisier spells when it was in AGC mode.
