[Elecraft] K3 Rx antenna

[Gary Smith]

Hi Mike,

What you're suggesting sounds like a good idea. I don't often use 
diversity because of the dB loss and the stations I am usually trying 
to work are the faintest ones out there. instead, I use the two 
receivers linked on the same frequency, that gives me the best 
sensitivity and I just listen in stereo.

My goal is to be able to select the option of hearing from only the 
Rx antenna and nothing from the transmit antenna. I use my Rx as a 
beam in that I can null out undesirable signals &/or peak the station 
I am listening to. The transmit antenna hears 360 degrees and I want 
to at times eliminate that. I figured with all the options on the K3 
that there would be an easily selectable way to hear the Rx antenna 
on both receivers just like you can hear only the Tx antenna on both 
receivers. And maybe you can? I haven't figured out how to do that if 
it is built in.

73,
