[Elecraft] KAT500 Isolation

[kq5stom at gmail.com]

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.
