OK Don...maybe I should go to a single signal as I have a hard time
hearing any change tweaking L3 & L4 on 80 mtrs...I have less than normal
hearing...I have a Heathkit RF signal generator so maybe if I put a signal
in about the middle of each amateur band, that will allow me to peak for
maximum signal...
