What potentiometers are you turning for a match ? The ones I am thinking of are for SWR protection and not for matching to the antenna. They are near the back of the amplifier board. Some amps do have matching capacitors on a board to the right of the main amplifier board. Your use of Yahoo! Groups is subject to http://docs.yahoo.com/info/terms/
