Hi,
Thanks for reading this message. I have exchanged my FT-847 for an IC-910H and now when I try to work VO-52 my UHF uplink signal interferes with the VHF downlink. Are the any people out there that experience the same with this combination?
I tried with and without pre-amp, RHCP and LHCP but the problems doesn't go away :(
I do know that there can be problems when working FO-29 and a mode-j filter can solve this, but I never experiences this when working VO-52.
