Jon;
Using the dsb dongle which is a CM108 chip based usb audio
interface.... one of the internal I/O pins of the device is mapped for
each ptt and cor.. BUT.. COR is not really needed as the device DSP can
handle signal to noise squelch and will work better on its own on raw
discriminator.. PTT is required and if you build your own dongle.. you
add a ptt transistor inside the device... It is a USB Sound FOB... I
ordered 5 of them for about $7.00 ea...
Information on the modifications is published... Google "CM108 usb sound
fob app_rpt" and you should find several links.. or start at the
allstar link page..
