[Elecraft] Signalink and K3

[Edward R Cole]

Art,

First off, by mentioning the use of the LP-Pan in the response to not 
needing to use a Signalink, I probably gave too much info (muddied the water).

I bought the emu-0202 to run with my LP-Pan since it was recommended 
(simple answer).

Now to address your question.  Yes, I needed to use a SDR (I chose 
the LP-Pan) to produce a IQ baseband output for the software I wanted 
to run (eg. MAP65).  For this application I am not using the 15-KHz 
DSP of the K3 at all so not using the audio lines to the 
computer.  The reason is that I needed faster A/D for wideband 
spectrum (90-KHz) display and the audio output of the K3 is limited 
to 4-KHz.  I do use the RS232 I/F for keying the K3 Tx with the DTR line.

However, I can run JT65 using the 4-KHz audio line-out from the 
K3.  For that all that is needed is a soundcard.  I use my emu-0202 
because my internal soundcard "crapped out"; I disabled it so I could 
use the external soundcard.  JT65 can display up to 4-KHz.

I am not the person to answer running multiple simultaneous soundcard 
applications because it don't.  But I suspect there is a way.

Hope that clarifies things??

Ed, I presume you're running some I/Q processing with the LP-PAN. Are you
doing that while running a computer based digital mode? Are you using a
separate audio interface for the RX & TX audio in those modes? Is it
possible to have to sound cards connected and running at the same time?
