This is an interesting idea. But how is this, I have set up my K3 with the
main and sub for use as independent receivers in e.g. a DX pile-up. Don't I
then need to open the K3 and reconfigure/rewire it for use as a diversity
receiver?

To have the second receiver and not use it for diversity is a tragedy.
Probably true. But I very rarely have enough isolation between my
antennas. So if I try diversity, the front end protection relays start
buzzing when I transmit. The consensus
Sverre,
No internal reconfiguration should be necessary to turn on Diversity
receive. Ideally your sub and main roofing filters should be matched
for diversity receive. I would think the filter selection should be
more permanent and would not be subject to reconfiguration.

In a word, no. The internal rewiring only controls where the subRX gets
its auxiliary antenna input from (BNC RX-only port or ANT2 on the KAT3).
Either one will work in diversity receive, provided you connect your
second antenna to the correct connector. For DX pileups, you would
normally use the

My antennas are quite close together and I find that the difference in
polarization is enough to avoid overload. (My verticals are truly vertical
though, not sloping wires.) I usually run just 100W. When I turn on the
1500w amp, it has its own relays clattering rather loudly (vacuum relay
Your second antenna does NOT need to be resonant to receive, either by itself
or with another in diversity mode. My receive antenna is seasonal so I have
employed antennas for other bands for receive when it is not up. While a non
resonant will not present as strong a signal, it also will not
I totally agree with Jim. Diversity receive is the only way I use the second
rx, and I never invested one cent in extra antennas for the second receiver.
For use with my horizontally polarized main antenna I just connect the
second rx to my existing vertical, which works fine even on bands that it
