AE5AW/Bill, in San Angelo, TX, inserted a roll of 50ohm coax between the
Ranger I and the grid input of his GU-76 amp.
He gets around 6 watts of carrier out of it, and the station sure sounds
good from out in West Texas!

You could wire in a big pot, to vary the screen voltage.
Driving your AM Rig without a scope,
is like driving your car at night, without headlights. (K4KYV)
