Cecil wrote about the 500kc experimental group. That's where my
receivers have been trained lately, and I'm having a lot of fun with it.
Cecil is quite right to characterize this effort as what we knew about
radio tinkering back in our heydays. Let me encourage you all to listen
for our beacons, and QSOs, remembering that these are not 24x7 stations.
Some of us go off air during storms, or out of town trips or when we
fall asleep at the switch. Many crank up the beacons just before
sundown and run them until sunrise. These are slow speed CW beacons; I
run mine at the slowest speed I can get out of my controller which is
around 9 wpm. A typical message might be VVV DE WD2XSH/15 15 15. And
that repeats every five minutes. The reason I bring this up is the
group is actively seeking reception reports so we can collect as much
propagation data about this segment of the spectrum to make the case to
the FCC we can operate without causing interference to any navigation
aids or other nearby government services. If you are so inclined, log
your reception reports into the database at 500kc.com - its quick and
only asks the basics like time/sig report/freq. The full list of
participating stations, and the band plan is posted at the site, but
here is the latest active CW list, compiled by Ralph Wallio, W0RPK, and
posted on the 600MRG mailing list. That mailing list, like this one is
an open list, as far as I know. Again, details and more at the 500kc
site.
So this is a target rich environment for your R-390 series receivers.
These are all weak signals, stations being limited to 20W ERP with
mostly very lossy antennas so its going to offer you a good test for the
sensitivity and stability of your 390. And at least two of the R-390
list members are active participants in the 500kc group. (Hi,
Conard). I have QSL cards for reception reports for WD2XSH/15. Give a
listen. I'd love to get a hundred reception reports Wednesday evening!
(if this table's format is screwy, sorry. better copies available
directly from me)
