[Elecraft] K3 Phones / Diversity Question

[Jim Bennett]

Hi Scott, yes - there is a separate antenna. I have an 88 foot long doublet connected to ANT 1 and a ground mounted Hustler 5BTV connected to Ant 2. In CONFIG, I have KRX3 ANT = ATU. So, if I understand correctly, Main uses Ant 1 and Sub uses Ant2. But, I just did an experiment and unhooked Ant 2 while listening to the Sub w/o Diversity turned on. Signals did not drop off. So, it sounds like they are sharing Ant 1. Time to putt off the top cover and see what I've done. Stay tuned…..

When I turn on the SubRX, it is still OK; I get Main audio in the left ear and Sub audio in the right ear. I know I'm getting the Sub audio in the right ear, as I can turn the sub VFO and hear the frequency change in my right ear. BUT, as soon as I turn on Diversity, I get almost no signal in the right ear. It isn't silent - it's just that the signal that is pounding in on the Main is nearly inaudible on the Sub. If the signal being received on the Main is less than S7, I can't even hear it on the Sub with Diversity turned on. If it is an S9 or greater signal, then I can just barely hear it on the Sub when Diversity is turned on.
