K3: KAT3 as RX-only

[Mike B-12]

I'm looking at the options for a RX-only antenna on a stock K3.  I understand
that the  primary way of doing this is with the KXV3.  However, since I don't
have a need for the transverter interfaces, or running a 2nd rig off the RX ANT
OUT jack, I think the KAT3 will be more useful in the long run for me.

Per the FAQ, "The second antenna on the KAT3 can also be set as an RX antenna in
the menu configuration."  I take it this means that, e.g. I can TX on ANT1 and
the K3 will switch over to ANT2 on RX.  Cool.  My concern is that I (or my kids)
will accidentally switch the TX over to ANT2, and my planned RX-only (truly,
RX-only) antennas will get fried.

Is it possible, via the menus, to make one of the KAT3's jacks as "RX only," and
not just "RX"?  I read through several emails back in the August 07 time frame
concerning this topic, but I didn't see my specific question brought up.  Also,
much of those conversations revolved around use of the second receiver.

Mike, I don't think the K3 will do what you think it will.  The non-transmit antenna (ANT1/ANT2) can't be used by the main receiver, only the subreceiver.  Look at figure 3 on p39 of the manual.

I'm sure someone will correct me if I'm wrong.

Barry, that's the way I read it too.

Brett, under your option #1, you failed to mention the constraint that
ANT1 or ANT2 selection for the receivers must match the transmit
antenna selection.  This was the essence of Mike's original question.

OK guys, thanks.  That is what I had suspected, as I didn't see it diagrammed
the way I was hoping to use it.  That's OK, though - I can still configure the
K3 to operate the way I want it to via the KXV3.  Gotta love modularity.
