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
signal appears below the carrier. Also it makes for a nice 2nd receiver
with good detected audio for most all modes.
There are many other software applications for the SDR receivers. Most
are FREE which is the better part while some get really sophisticated in
their implementation and features. As to how they interface with
various logging applications, I don't have a clue.
Glad to be of assistance.

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

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:

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
