You may remember I posted a question on the reflector about my low power output on my 471h. Well, I got up with the tech and he told me it is the mixer module on the rf board # 412e-h. He told me the part is no longer available. Does anyone have any suggestions? Thanks to all who responded with the trimmer cap problem but it looks like that is not the problem this time. Thanks in advance. Matthew kg4ipx.
