[Elecraft] K3 AFSK RTTY overdrive - no ALC

[Chad WE9V]

All cables were removed, other than the LINE IN into the radio, including
the line out.  Headphones were worn to listen to the monitor audio.  (Okay,
so I didn't mention the headphones, but they are electrically isolated from
everything else.)
