Hi Eric,



Only 2 cables for this unit.   USB cable from interface to pc.   The 
interface also draws it's power from the USB, so no  external power is 
needed.    Second cable goes from the interface to  the radio.   Where it 
connects depends on which radio you have.    They supply 1 cable for your 
radio of choice.  It may go to the front panel mic, although  most more 
modern radios will connect via an accessory or data jack on the rear. 
Most of the accessory or data jacks will also pass received audio from radio 
to interface.   If connecting to front panel mic jack, you may have to get 
received audio from  a speaker jack unless audio is somehow available from 
that front panel jack.

Of course you should walk before you run.    To receive PSK or any digital 
mode, all you need is  a audio connection from the radio to  soundcard input 
on the pc.   No interface or anything, just 1/8 stereo cable into soundcard 
line in and other end to some audio source on the radio  like an external 
speaker jack.

With this simple connection and your software of choice, you can see if it 
works. If you can't get the software to decode the signal and get your 
screen reader to spit it out in some understandable fashion, you're dead in 
the water and no sense  going further and spending money on  interfaces and 
other junk.
