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 73 de M0BMU
