K3 RX ANT OUT
Locked

Is there a diagram anywhere showing the internal connections to the RX
ANT OUT jack? It obviously isn't working as I expected. I thought RX ANT OUT would pass whichever of TX ANT or RX ANT that was not selected by the main rx. But with TX ANT used by main rx, RX ANT is not getting passed to RX ANT OUT as I expected it to be.

RX ANT OUT is connected to the TX antenna 1) when not transmitting,
and 2) when RX ANT is selected. That is all. The function is there to allow patching in a preamp or filter for receive. The relay that does the switching has the RX out connected to a contact rather than a pole. Sorry. 73, Guy.

Joe,
Out of passing interest I tried to find the references you made below without success. Would you be so kind as to give me a direct link to the schematic and the RF board. I need to consider my internal jumper to make some SUB receiver changes to antenna connections. Thanks a bunch. 73, Bill K9YEQ -----Original Message----- > Is there a diagram anywhere showing the internal connections to the RX > ANT OUT jack?

Here’s a distillation of the situation that I derived from the schematics, for my particular radio configuration.

Joe,
Thanks. I was looking at the actual manual and the pages didn,'t relate. Another post simplified what I was looking for. I appreciate your time to clarify the reference.
