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.

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.
