[hpsdr] PowerSDR + Ozy/Janus + Softrock TX/RX

[Bill Tracey]

Hi Don,

The xmit support for the Soft Rock in the current Janus/Ozy modified 
version of PowerSDR is likely to be a bit flakey - I did not really 
test the Soft Rock xmit paths.  I suspect there's a bit of work to be 
done to make the J/O modified version work for xmit on a 
SoftRock.   Also probably have to do some work on how to handle the 
T/R switching -- typically that is done with a com port on the PC - 
clearly in the case of J/O we'd want to use one of the GPIO lines on Ozy.

I'll add Soft Rock xmit support to the list of things to do.

Regards,

Bill (kd5tfd)
