One approach might be something on the order of what Canada  did, but the CW

collector circuit of the
transmitter stage that supplies radio frequency energy to the antenna; or
(b) where expressed as radio frequency output power measured across an
impedance-matched load,
(i) 2,250 W peak envelope power for transmitters that produce any type of
