Dear LF Group,

As art of continuing investigations into antennas, grounds, etc., I am running a beacon at the moment on 503.5kHz - I am testing a small "/P" antenna similar to what G3CWI proposed to use a couple of weeks back. It is a 9m high "umbrella" with 4 x 5m long top loading wires sloping at about 45degrees. Ground system is 4 x 20m radial wires.

The beacon is transmitting an 8wpm CW identifier, followed by five 5 second dashes at reducing power levels in steps of 6dB. The maximum ERP is somewhere in the region of 100mW ERP. The sequence repeats every 2 mins roughly.

I'll leave it running until after dark at least - any reports would be very welcome.

Cheers, Jim Moritz
