KAT500 Isolation

[KQ5S-Tom]

I decided to hook my dummy load to antenna two on the KAT500 with my main antenna being on antenna 1.  When I get a strong signal on my main antenna and switch the KAT500 to port 2 (dummy load) the KAT500 I can still copy the signal on my K3S though the strength is down from S9+ to about S2.

I can keep the KAT500 on antenna 2 (dummy load) and disconnect the dummy load from the back of the KAT500 and still hear the signal.

I was using an Alpha Delta 4 port coax switch to switch between my main antenna and a dummy load.  All was well.  No signal being heard when I switched to the dummy load. In this configuration I had antenna 1 from the KAT500 going to the Alpha Delta switch and then out to my antenna.

ISTR that the isolation between antenna ports is around 30dB. Allowing for
inaccuracies, your S9 down to S2 reading seems entirely reasonable.
