Hello = Roger,

 

Big earth electrode antenna allows = transmitting on 136kHz with average = results.

A couple of Gs came on. G3XIZ (46km) = was 2-3dB better S/N on the earth-electrodes than on the compromise = vertical. He is end-on to the "loop" in the ground. = G6AVK was not copied at all. He is orthogonal to the = "loop" in the ground. I was quite surprised not to spot him at = all though.

 

Conclusions? The earth-electrode = "antenna" in the ground is quite effective at 136kHz, but more = directional.

 

Next season I will definitely try an , E-field = probe on RX!

 

No great DX, but = experimentation!
