Hi Syl,
Have used a C31XR in CQWW SSB with Tri feed with two amplifiers - The only
filters were W3NQN 300 watt filters between the Radio and the amplifier - no
noticeable signal detected on either rig.
Coax was RG8X
RIG 1 was FT1000MP Emtron DX1
Rig 2 was a FT2000 VL1000
Good luck

Hi Syl,
I am not sure what you mean. The IC7610 doesn't do full duplex,
therefore you cannot receive and transmit simultaneously.
If I were using the tri feed with two radios I would want nothing less
than the 4O3A combiner for full isolation plus individual bandpass
filters.

Combiner – 4O3A

When analyzing a 4O3A Triplexer System investment bear in mind the savings in
antennas, towers, feedlines and maintenance that will accrue. It’s worth noting
that ...
In fact I don't know anyone who has a working tri-feed, and this
requires only a single coax from your tribander, better isolation too.
