Replace the T connector with a hybrid splitter ... connect
one output to the Aux Ant (Sub RX) and the other to the RF
In (Main Rx). I like to feed the splitter with a RX antenna
switch - each of the RX antennas plus a line from the RX Out
jack. Ideally one would put a splitter on each RX antenna
and feed separate switches for Main RX and Sub RX but that
begins to get a bit complex (maybe someday with four outputs
to route receive antennas to one of two transceivers <G>).
You can build your own magic-T splitter from plans at Clifton
Laboratories:

I've used old "broadband" MATV/cable splitters (typically
specified 10 - 1000 MHZ) from the "old days" with no issues
all the way down to 160 although the isolation may not make
full specs that low.
If you need an off the shelf commercial product, look at the KD9SV
unit: http://www.dxengineering.com/parts/svp-sv-rsc (less expensive
than a lot of others). Or search for a surplus unit on eBay.

My order is in Queue for a K3s.
I currently have a K3 with sub Rx and have a HI-Z Rx antenna I use
with the K3. Sometimes I like listening with only the Rx antenna,
sometimes I like listening from the the Tx antenna. When I use
diversity I want to hear from both the Rx and main antennae.
With the K3, what I have done with the Rx coax is attach it to a T
connector with one end attached to the BNC connector {27} Aux RF,
located below ANT 2 and the other leg connected to the RX ANT - IN on
the KXV3.
Once I upgrade the two KBPF3 and Sub Rx board, I will migrate the Sub
RX to the K3s
With the K3s, how should I connect the RX antenna to be most
effective with the K3s & diversity? As I have it now?
Thanks,
