Congratulations, Laurence. That codar is a pain here too, increasingly in
the evenings.
I've been meaning to report on Sunday afternoon's HiFER activity in SE
Kansas, but have been tied up with work for most of the day and this
evening, too. That afternoon, we had severe thunderstorms within 35 miles
that obliterated anything below the AM broadcast band...S9+40 or more,
continuous. A little static showed up at 22 meters, but combined with less
than ideal propagation, only EH to come through for a while. Not even old
reliable MP was visible. I went and did other things on the farm until
sunset, then checked the band again before leaving. Wow, what a difference!
There were MP, both SIWs, EH, and NC. SIW and EH were competing at times to
see who could light up the display the brightest, resulting in some odd
looking intermod products from the clipper, which was keeping the radar
pulses to a modest roar. For a brief while, some of those artifacts had me
hoping RY might be back on in DFCW, but not so. The CW IDs of MP and
"plain" SIW were clearly audible most times.
Then suddenly, it was as if SIW switched off...or switched into a dummy
load, or something.
The others continued, although NC wasn't as consistently strong. But I did
go on to copy MTI by ear briefly (it had been showing faintly on Argo for a
while), and AJO for a few ID cycles at a time (the DAID was nicely
conspicuous on Argo), and finally GNK, up to seven clear cycles at a time
and visibility on Argo between. I would like to have stayed out longer.
The severe stuff moved farther away by evening, but light showers started up
right over the farm so I gathered the gear into the car and returned to
town.
I hope to eventually post (somewhere) a big composite of the QRSS3 captures
from Sunday, but the QRSS10 look at SIW slant mode should be attached.
