I'll let someone else more knowledgeable than me expalin the finer
points of how the radio and PC communicate the audio but as far as
playing the audio through your PC speakers, it can be done. Just run a
1/8 inch stereo jumper cord between the phones output on the 1500 and
the line input on the PC soundcard. THat's what I do. If you're lucky
like I was there will be no ground loops caused and that's all you will
have to do. If you happen to encounter a ground loop then you will have
to employ some type of isolation. I believe you can also accomplish the
same thing with VAC if you configure it a certain way but I don't know
how and I think there are latency issues. Have fun with your 1500, the
RX is absolutely amazing for such an inexpensive rig!

I've been playing with my new Flex-1500 for a couple of days now. BTW, plugged
it into my laptop, installed PowerSDR (and VspMgr, and VAC, and MixW)... DONE!
Worked first time. I took all the defaults. No pops, no clicks, no problems
at all. With all of 3 watts I had PSK QSO with someone in Panama. I already
love this radio.
But I have some sort of conceptual gap in my understanding that I'm SURE
somebody can clear up for me:
1) The signal is filtered and demodulated by PowerSDR in the computer... so why is
the "phones" connection on the front panel of the radio? How does the audio
GET there (back across the USB connection)? Is there a way to use my laptop's sound card
and speakers to hear the radio audio?
2) Similar to the above, but for the microphone connection: The mic
connector is on the radio, not into the computer. Does the mic audio travel
back across the USB from the radio? Is there a way to use my laptop's
microphone as input?
Confused,
