Please keep in mind that the RX IN/Out solution is after the K3/K3S Low
pass Filters. So for instance if you want to monitor 15 meters while
listening to 40 meters, the signals will be greatly attenuated.
There will be no attenuation if you are listening to a band below the
frequency the K3
Actually, Don, that is not the case. Depending on your software, you can
use the SDRplay as a panadapter using either IF or RF (RX Ant In/Out). I
use my SDRplay both ways. The software has to be told which connection you
are using in order to label frequencies correctly in the display, but they
Drew,
Your subject line indicates that you are using SDRPlay as a panadapter,
and in that case, you would want to connect it to the K3 IF OUT and tune
it to the K3 1st IF of 8.215 MHz. The display will show you what is in
the K3 IF.
If instead you are using it as a sub-receiver, you would

I just got a RSP1A and am missing something here: if I connect my
receive antenna to the K3 RX In, then connect the K3 RX Out to the SDR,
what is the use of the tee?

Yes and it gives you a much wider RF spectrum. It is protected when you
transmit thus no switching or muting is needed. I've used it both ways
and found with the IF output signal to the SDR that the sidebands were
inverted. Thus a LSB signal appears as above the carrier while a USB

Thanks for the idea. Works great and got me away from the problems using
the IF out.

If it will tune to the IF frequency of about 8.2 MHz. From experience,
without an up conversion added, they won't tune that low.

I suppose, but I've not tried it. The cheapo dongles don't cover HF, though.

I used HDSDR software and a BNC T and a couple of short coax jumpers
from the RX ANT output back into the RX input. Activate the feature
from the front panel of the K3S. The input impedance of the RSP-1

Isaac,
I did exactly that, using the HDSDR software. I used the RX ANT output
(must activate it from the front panel of the K3) to feed the antenna of
the RSP1. You use a BNC tee to feed the antenna back into the K3.
Purists use an RF splitter instead of a tee. I have a YouTube video that
I would recommend that you use Win4K3Suite, really does a nice job of
integrating the RSP and K3.
No relationship with Win4K3Suite, just a satisfied user.
