I can turn up the power control and it will increase to where it should be, even though the power control is allready set to 120w. After a turn or two the power goes back to approx. 100w. I can tap tune again and it will drop to approx 30 w peak on ssb. Talk and turn the power adjust up, even though it says 120w brings the power back up. It's then OK until I tap tune again!
