Antenna current measures less on the PAR end-fed with strapped feeders yet this seems the most effective of these antennas. ERP is less than 5mW.
|472kHz WSPR unique reports Sept 4th 2014 to 2028z|
UPDATE 2100z: Best spot of my 472kHz WSPR signal this evening is now from PE1RKT (285km).
UPDATE 2140z: DK7FC continues to put out a huge WSPR signal on 472kHz. He was audible by ear at -3dB S/N a little while ago. He runs 1W ERP.
UPDATE 2200z: Each TX transmission period gets me 4-5 reports, which goes to show how effective less than 5mW ERP on 472kHz can be.
