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!)
