Folks,
After a hiatus, my 10 meter amateur radio propagation beacon is getting back
on the air, just in time for the beginning of the new solar cycle (Cycle
24). It is running now and through the weekend for a shakedown cruise, in
which I will do some tests and track down and attempt to reconcile any RFI
or equipment problems.
The beacon antenna is located on the roof of a high rise building (21
stories) in the Ballston section of Arlington, grid square FM18kv. It is a 3
dB gain (theoretical) quarter-wave vertical antenna, fed by a RadioShack
HTX-100 10-meter radio operating with 25 W output. However, there is about
100 ft of RG-8 type coax in between, so the power into the antenna is
significantly less than 25 W (this is one of the parameters I will be
measuring).
Take a listen in CW (or SSB) mode on 28.210 MHz. Initial reception reports
are welcome! Reports of non-reception are also welcome. If your radio
doesn't do CW or SSB mode, listen in AM or FM mode for the CW carrier going
on and off.
I plan to do a lot more beacon development, including possibly adding a
simultaneous 2m beacon at the same location, and adding a dedicated web site
for information, reception reports, statistics, and maps of confirmed
reports. I hope to keep this going throughout the entire Cycle 24.
Cheers,
Andy
