Well my problem is persisting. I TUNE to full power key the mike and only peak 60 % of the 1.5 kw. Then I will TUNE again and quickly key the mike and it will peak at the full 1.5 kw only to revert to a lower level on subsequent keying of the mike. this has not happened on any other of the day since the radio went QRV any help appreciated 73 de todd WB2ZAB
