David & Doug,

I knew there were some audio issues with usbradio, but as I mentioned, I'm
just 'playing' with another node to learn more about configuration options.
I thought usbradio was already rolled into the package.  From your note
(David) I see how I screwed up the rxchannel configuration in the rpt.conf
file. Thanks for the clarification.

I'm patiently looking forward to the new release. If you need a lunkhead to
test the Beta for idiotproofing, I'm your man <grin>.  I can usually find a
way to screw things up that others miss....

Many thanks to all those who blaze the trails for the rest of us to follow.
