Hi Dimitry,
I know of this filter, but these are for working FO-29 when the uplink
is 145 and the downlink 435.
The Harmonics produced by the 145 uplink signal interfere with the 435
downlink. Now I experience the
same with VO-52 but there the uplink 435 and the donwlink 145 ???
So why is the 435 uplink interfering with the 145 downlink ????
Could this be a harmonic problem???

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.
