I am having problem with 2M uplink overloading (desense) the 70CM downlink, resulting in not being able to use RS-44, FO-29, or SO-50. It is the same antenna system that I used with the FT-847 and I experienced no problem at all with the FT-847. SWR on both VHF/UHF is quite low using M2 CP yagis on fiberglas boom, 11 feet apart. I have the problem whether I use the preamps, or not. Even at 5W out, it is quite noticeable. Anyone else had this problem? KJ4EU Jerry
