The radio has two round din jacks on the back, I assume that one is used for
connection to the computer for echolink. Haven't tried it. I think I got
the manual from
http://www.icanworkthisthing.com, somebody I think from this list made a
nice audio tutorial. One thing, their are two vfo's. One goes from 136MHZ
to 1300MHZ. The other starts with the aircraft band and goes up to around
900mhz.
