I just replaced the input, output relay and fired the unit up and for the first time since Ive owned it, it showed a carrier higher than the exciter wattage! But I noticed the input SWR was almost 5-1 whether the stanby switch was on or not. Well if I bypass the BTL with stanby on and just let the radio go through the amp the SWR fell to 1:1. But the second I turn standby off the amp has 5:1 swr but it still putts out a 400watt carrier! How can I adjust the input swr?
