[Elecraft] AUX_RF vs RX_IN

[Brett Howard]

I'm mulling something over in my head while writing some micro code on
way too little sleep...  Anyway last year at FD I had some issues with
my COR in the SubRX activating when we were doing diversity receive.
Sometimes it was activating when we transmitted on our antenna and
sometimes it was activating when the other station transmitted...  But
it only was doing this on the subRX as soon as you got out of
Diversity there were no issues.  Not sure why we only were having COR
switching issues only on the sub as it seemed to follow the SubRX when
the antennas were switched.

  My K3 was configured for the SubRX to be on the unused KRX3 port.
I've now moved it over to the AUX_RF port....  I was figuring that I'd
use an I.C.E. 196 (RF Limiter) in line with the second antenna and run
that into the AUX_RF port.  That would ensure that I wouldn't
accidentally transmit through that port and what not...  There is also
the added benefit that you don't have to worry about having VFO B
below that of VFO A as the LP filters are out of line on that port (if
I remember correctly).  However in thinking these thoughts I figured I
could get a lot of the same stuff done using the RX_IN port.....  If I
was to use the RX_IN port that gives me a lot of those benefits and I
could then move the SubRX back to the unused KANT3 port then I'm able
to transmit on that second antenna if its deemed to be beneficial to
do so in that situation (ie more flexibility)...

Still mulling things over but interested to hear thoughts of others on
this topic...  Sorry for the rambling nature of this message but its
only a partially formulated thought so thats all I've got at the
moment.... ;)
