low band CDM-1250 tx problem

I have a low band CDM-1250 42-50 MHz and am only getting 2 to 3 watts power out. The receive is excellent. I have searched a few posts and have found PA bias issues and PA issues. I would like to know what the PA bias settings should be (or close to it). One thing I noticed in Iwhen read it for tuning the bias voltage was "0".

Can someone also advise anything on known PA problems? I just don't have much experience with the waris series.
