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). ------------------------------ Message: 48 Date: Sat, 26 Mar 2011 21:45:46 -0700 (PDT) From: Geoffrey Wolf AB3LS <[email protected]> Subject: Re: [Elecraft] Forums? To: Elecraft <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset=us-ascii 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. 73 Geoffrey Wolf AB3LS 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-1.4kw, 432-100w, 1296-testing*, 3400-winter?
