Saw this message after a late lunch and went back to the farm to check.
Although 2200 m was out of the question today, lightning noise is usually
less of a concern at 630 m, and it seemed within the realm of possibility
that +23 dBm just might be enough.
However, the S-meter showed the noise to be just as bad at 630 m this time.
Moreover, it was of a different kind...the higher frequency crackling of
discharges within a cloud that precede actually lightning bolts...and there
were a LOT of them. That suggested to me that some electrical activity
might be closer than the radar indicated when I left the house.
After about 40 minutes of watching with WSPR 2.0 and Argo, I could just
about convince myself I sometimes saw the perpetual broad QRM line under all
the noise, but no signals appeared and there were no decodes. The QRM line
was a smidgen clearer after I narrowed the IF bandwidth to 250 Hz and drove
the clipper hard, but just barely.
Giving up on LF and MF for now, I tuned up to look for HiFERs and was having
little luck there either (not much noise, simply no signals to speak of)
when suddenly a rumbling from outside overrode the generator noise. I made
a mad dash to short the antenna and grab the buffer amp, then returned to
remove gear from the building and close it up.
After an entire springtime of near-drought, now that harvest season is
nearly upon us, they say we'll be getting this sort of weather every day for
the foreseeable future. DXing will be a catch-as-catch-can proposition here
for a while, probably favoring the morning hours most days.
