Hello Roy!  Thanks for the reply.  I found that the sound system in my
old laptop is in fact compatible with PSK31, so that solved that
problem.  Unfortunately, it has only one serial port, and it's connected
to my TNC for APRS use.  None of my radios have VOX capability, and it
seems a waste to tie up a serial port just for a PTT line.  I wonder
if there is a circuit that could be inserted in the sound card's output
line to activate the PTT.  It ought to be fairly simple, not much more
than a switching transistor and a few other components.  Of course, it
needs to be quite fast so none of the signal is lost.  Hmmm...Time to go
surfing again!
