as far as the audio you need a 3rd party program, Virtual Audio Cable, 
known as  VAC for short, to route the audio from PowerSDR to WSJT


PowerSDR uses CAT commands to talk to WSJT using virtual com port program


It might be ok for VHF hams.. but not for microwave operators.. It has 
no 2 meter capability for any of the higher band transverters.

there is ptt in and out and audio in and out located on the back as well 
as I2C Serial data port.. but no accessories made for it yet..its all in 
a db9 connector.. no easy to use rca plugs

there is a UHF sdr transceiver kit around.. I have it, but have not had 
a chance to work on it yet.. covers 1.75-700mhz with decent preamp and 
50 mW rf output.

> I'm certainly planning on saving some pennies to get one of these. One question that I have for current users of the Flex-Radio SDR software is regarding WSJT (digital mode) operations. Since the units include a built in soundcard, I assume that Windows would recognize that soundcard, and WSJT could be configured to work with the SDR without the need for an additional interface. Is this correct?
