All the radio controls are open source (www.linradio.com)
*except the SDR*. In other words, no. :-)

Don't know about the PCR1000. It's not one of my favorite
radios because of both engineering and politcal decisions.
Most of the WinRadio series is expensive. Furthermore, they
don't perform very well. They sacrificed a lot to get DC-Daylight
performance out of them. OTOH, the G303i ("i" for internal) is
a DC-30 MHz radio and is relatively affordable at $600.
There doesn't seem to be much of a reason that an external version
can't be built, but as I said, they haven't released an API or
board registers yet.
