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
SDR is well above 50 ohms and thus I didn't observe any loading or loss
of the received signal.
As to software, HDSDR was my favorite and easy to setup and use. I added
OmniRig to allow for full interface to the K3S. This provides two way
communications between the radio and computer. Thus any change on the
radio is effected the same on the computer and any change on the
computer is resolved on the radio. Of course there is capability in the
HDSDR software to have your choice of the radio following the computer
or the computer following the radio or neither, thus both being
independent.
An excellent and economical approach which I used several years and with
different radios as well. That is......until I purchased a P3 to go
with my K3S.

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 shows the results: https://www.youtube.com/watch?v=KusmkeLdfwE
If you need further help, let me know.

Hello all,
I am considering using an RSP1 SDR with my K3. I will probably use HDSDR
software to start with.
Can someone point me in the right direction for the whole procedure?
TIA
