Re: [Elecraft] Using RX ANT OUT for a second receiver

[Joe Subich, W4TV]

Pete,

I've been doing that to feed my SDR-IQ and it does not seem to be
a sensitivity problem.

*NOTE* the RX Out/In loop is *after* the transmit lowpass filters
and as such they will impact the ability of your QSR-1 to receive
on bands above the one in use on the main receiver.

Re: [Elecraft] Using RX ANT OUT for a second receiver

[Randy Farmer]

I do this to feed my ancient R-4C as an auxiliary receiver. I built up a 
special RX antenna relay switching matrix to manage feeds to the Main 
and Sub receivers with a Mini-Circuits PSC-2-2 embedded in it for this 
purpose. The splitter can be switched in or out to share the Aux R-4C 
with the K3 Main input. It works great.

G4AON has been doing this for a long time, to feed his Perseus:

Pete,

If the 3 dB does not bother you, then I would say "do it".

[Elecraft] Using RX ANT OUT for a second receiver

[Pete Smith N4ZR]

Any reason not to use a magic-tee splitter between the RX ANT OUT and RX 
ANT IN ports on a K3 (no antenna tuner) to feed the received signals 
simultaneously to a second receiver? I want to be able to use my main 
antennas with my QS1R for Reverse Beacon functions. I realize that will 
cost 3+ db on each port, but that doesn't look like a show-stopper.
