For simple receive-only SDR sw this will work as most have a soundcard interface option, but I still see a problem controlling the KX3 VFO, mode changing, and transmitter Keying without sw dependent drivers for the KX3. This is definitely out of my expertise but based on getting new hardware to work with certain SDR programs.
I'm not saying it can't be done; I am saying a computer programmer will have make a KX3 driver for some SDR sw out there. LP-Pan is the most simple of SDR and is not tuned and is receive-only. Spectravue controls the frequency in the SDR-IQ via USB. I can use Spectravue for the LP-Pan because the only connection needed is the soundcard (which Spectravue supports). But without a driver I still don't see how Spectravue can control the KX3. You say CAT (that's not a universal standard, is it?). I'm sure, in time, that sw programmers will support interfacing to the KX3 from many of the SDR programs out there. Initially, many do support soundcard input as long as the KX3 VFO manually tuned and transmitter manually keyed. An example is JT-65 which probably will work if the KX3 support use of RTS or DTR for keying PTT as modulation is via the soundcard and reception is via a soundcard. Probably most of the psk and rtty programs will work for the same reason. Linrad is complicated. It will work for receive-only but when combined with MAP-65 there is rig-control and I am uncertain that will work with out a specific driver being added for MAP-65. I have not used PowerSDR so cannot speculate on it. Like I already said this is outside my expertise, so just a guess. 73, Ed - KL7UW ------------------------------ Message: 5 Date: Thu, 8 Dec 2011 19:02:26 -0600 From: Tony Estep <[email protected]> Subject: Re: [Elecraft] kx3 and sdr software To: [email protected] If I understand it correctly, the KX3 puts out I-Q audio that can go directly into a sound card, and has an RS232 port that can go directly to a CAT connection on a computer. Some SDR hardware receivers or transceivers interface with SDR programs via USB to control frequency. An example is the Softrock Ensemble, which uses a Si570 chip to generate the local oscillator frequency. The Si570 is tuned via a USB connection which in turn is linked to a program like Rocky by a driver. The Softrock does not have CAT control, and Rocky will not send CAT commands. But for the KX3, none of this is relevant. No drivers are needed. It will be exactly like hooking up LP-Pan, which just needs a sound card and a serial connection.
