I am very encouraged by the response to my comments on our
erp limit.
Regarding ground loss, the best way to reduce this is not to bury
wire in the ground but to put it in the air !  1 metre of wire in the air
is worth 10 in the ground, and it does'nt have to be in a straight line
either just so long as it covers new ground as it were. My 136 now
500kHz ant has 600 feet of top load in 3 zig zags and I get about 30
ohms resistance on 136 and about 15 ohms on 500. So I dont need
many watts to get  0.5 amps int the vert section.
