Mark - I have the same problem with the XV222 indicating IF overload when I operate 6M. In my case I drive the XV222 with a TS-2000X. This is in a rover ssetup with the 6M and 2M antenna separated by about 4 ft. I will try your fixes. To now, I have just lived with it. - Duffey -- KK6MC James Duffey Cedar Crest NM
