TNX for the efforts!
My TX setup:
Big vertical on the 135m high tower - ~ 60...70m H eff
valves PA - 80...120W Output
Iant (current) in ant 2..3A
P(ERP)=0.00033 * A^2 (for 137KHz, by RA9MB)
A=I ant*H eff, I ant in A, H eff in m
P=~ 5...15 W ERP
Some details look on http://136.73.ru/ed/index.htm
PA (new now) is connected directly to the electric system (without
transformer) and compact
