[Elecraft] Multiple PC sound cards...

Fri Jan 24 12:20:01 2003

Hi

Sounds like a job for an audio mixer or maybe run radio a on the left
channel and radio b on the right. You could use one sound card and do all
the switching in the mixer or swing the balance to left or right to select
the appropriate radio. I don't know but it may work.
