Ed Your right the WSJT modes at QRP power opens up a whole new world to the KX3 and with the new JT9 mode the possibality of QRP DX on 40/80/160m like never before.
I've been trying very hard to convince myself of all the reasons that I don't need a KX3, the list grows shorter........... 73, Fred/N0AZZ -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Edward R Cole Sent: Sunday, December 23, 2012 2:25 AM To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] I've been thinking! Gary, VK1ZZ: Not sure what you mean by "front end", but Elecraft chose to design the K3 with the digital signal processor included (embedded) in the radio. They also developed the software which defines operation of the radio (SDR= software defined radio). At the time this was developed SDR's were not very plentiful for the amateur market and the few available most often did not come with software; the buyer had to "roll his own" (e.g. be a software designer). This held down the appeal of SDR for a good while. The K3 came complete with software and processor included which required no external computer. Elecraft chose to call the software "firmware" as it was downloaded into non-volatile memory. Thus is was firm until a new version was downloaded. However, Elecraft did not provide external connection to the IQ data stream or baseband so no second-party sw could be used using a computer. That was both good and bad: good such that the radio was stabile since firmware was under Elecraft product reliability control, but bad for use of any other sw programs. In the KX3 they have provided external IQ baseband output so one can try any number of SDR programs with the KX3 (caveat is you may need a bit more understanding of computers to actually get many to work with it). I suspect that there will be many sw gurus that will come forward with versions to work with the KX3. Of course one will need a computer with good soundcard to run them. In time I will probably play with trying other sw with the KX3. JT65 and JT9 probably the first. They will not provide full access to the control panel, though. Maybe PowerSDR can be modified to work with the KX3? Drivers must be developed for each radio that one uses a sw radio program (and that is hard part). 73, Ed - KL7UW ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
