Geoffrey,

I am in the process of setting up my K3 with two LP-Pan feeding a 
M-Audio Delta-44 dual-channel soundcard.  The reason for the LP-Pan 
is to provide I-Q signals to a computer so that custom SDR sw may be 
used (or developed).  The K3 has an internal MCU with Elecraft's 
proprietary sw, but that is not open for sw developers to 
access.  Therefore, the standard K3 falls short of its promise as a 
SDR.  Using the LP-Pan as outboard SDR converters one can use the K3 
with other SDR programs.  That is the second part of the SDR 
"promise" of non-obsolescence.

This is not anyway meant to be criticism of the Elecraft staff and 
their amazing continual development of the K3 firmware.  For most of 
us having them do the sw development is welcome (so we do not have to 
do it ourselves).

I am in a third category of wanting to run a different SDR program 
using the K3.  In time the P3 may evolve into an open SDR with 
external connection to a computer.  The LP-Pan provide this now 
(other SDR can be used on the K3 1st IF in a similar manner).

Oh I had forgotten to add in the last email...

What I had meant when I said making a K3 into an SDR, I guess I forgot to
clarify that I meant. I was talking about using the IF from the radio into
something like an LP-Pan and sending the raw IF data to the computer for it to
process, separate from the radio's internal DSP. I find this great though
because beside the K3 being a completely independent SDR in a box, you can
extend it to use the computer's power as well and enhance the listening
experience. This is one of the few reasons why I'm ditching the Flex for a K3.
