[Elecraft] [K3] RX ant without KXV3?

[Martin Sole]

Hi Ilya,

This might be possible. Take a look at it he K3 schematics. Before I found a KXV3 I was considering this, certainly the IF out. 

As I recall on the main board there is a connector with the rf in and out. These are jumpered on the main board when no KXV3is fitted.

Then there should be a control signal to switch the relays for rx antenna routing. 

I think if you are reasonably technically proficient you can produce a way to make this work for you. You can probably do away with the relays if you use a jumper or manual switch when you don’t want the rx in-outfunction.
