I have an Omni d.  I have a problem when I push up the power, the radio 
starts fming, either on ssb or on cw.  With the power turned down to zero, 
no problem.  If I can fix this at home, I really don't want to send the 
radio in to the factory.  Anybody have any ideas of things to try here.  I 
compared the omni D with the corsair on the same power supply, cable, patch 
cord, and dummy load.  Both radios were grounded.
