MP 137 was much better this afternoon than last night!  I took a break from 
my parts inventorying and board layout for a hasty late lunch around 3 PM, 
then came back by way of the farm.  Static was intermittently 20 dB over 
receiver background in a 250 Hz BW, but usually only 6-12 dB above, and MP 
was down in the residual receiver noise somewhere below that.  The left side 
of the window is straight receiver output with very light clipping and Argo 
set normally.  I switched to manual sensitivity and increased the drive to 
my clipper, resulting in a pretty capture of MP.

As the afternoon wore on, I switched over to 495, where /7 and the mystery 
ditter were the only things to be seen in my 3-second Argo window.  However, 
when I later noticed a spare instance of Argo was still running in the 
background, tuned below 495, I saw there had been a very powerful carrier 
that was switched on a couple of times for 30 seconds around 494.970.  I was 
closing windows rapidly and didn't capture it before it was too late.  I'll 
have to go back another time and look again.  (Evidently, I need to keep 
multiple instances of Argo running so I don't miss anything coming out of 
the receiver!)
