Batboard

I have a MTR 2000 and recently it has been showing problem . I connected a Through Line meter to check whether it was connection or antenna problem and it was showing 40 watts when keyed ; after 10 mins it went down to 25 watts and again to 40 watts .Anyone with any idea to what is going on, maybe PA problem.Please advice.

Did you try to use the CPS to run a full test on the repeater? You could have a power supply issue.

Double check it with another wattmeter. I've seen Bird 43 thruline wattmeters do that before, if thats what you were using.
