[Elecraft] K3 + SDRPlay's RSP1 as panadaptor

[Bob McGraw K4TAX]

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.
