I'll address this one more time and then let it rest. SDR = Software Defined Radio. (i.e. the software defines it). The software is "in fact" the radio.
It has been a long tradition of ham radio to being able to "build it", yourself. For SDR that includes the software. If a commercial SDR is not open-source it loses part of what being a SDR is all about for hams. That being said, not many hams "build-it" anymore so, thankfully, Elecraft has given considerable attention to the sw (firmware). That is lacking in a lot of other SDR ventures. It also seems ham radio is split into: "programing capable hams" and the rest of us. And one more footnote on my project. I would have had to go with an outside SDR to obtain wide-bandwidth, in any case. the 15-KHz second IF restricts what can be done with wide bw modes or displays. Even Elecraft recognizes this with using the 1st IF for the P3. I think that should finish this topic, OK? ------------------------------ Message: 12 Date: Sun, 27 Mar 2011 07:11:51 -0400 From: Ed K1EP <k1ep.l...@gmail.com> Subject: Re: [Elecraft] Forums?

I don't see anywhere in the definition of SDR that the software has to open source. If you wish to develop your own SDR software, the LP-PAN is a perfect add on to allow you access to the IQ outputs for developing your own software or modifying existing open source software. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-1.4kw, 432-100w, 1296-testing*, 3400-winter?
