Ken,

Yes, that is exactly the way to do it, and that still allows you to
transmit through the main antenna. So in other words, you would select "RX
ANT" for the main receiver, and be sure to select the AUX input for the
sub-receiver (while "b SET" is engaged, tap the "ANT" button on the K3 to
alternate between "MAIN" and "AUX" and be sure you leave it on "AUX".) I
operate this way on both 40m and 30m with a Pixel Technologies loop
connected to the AUX input, and a small voltage probe RX antenna connected
to the RX ANT input of the K3, while using a ground plane vertical as the
main transmit antenna.

Depending upon the amount of power you're using, and the proximity of the
rx antennas to the tx antenna, you may want to consider adding some
outboard rx protection. I use the Array Solutions Model AS-RXFEP, and it
works very well.
