[Elecraft] Fwd: Speakers audio is gone

[Don Wilhelm]

Gary,

A stereo to mono adapter will usually not work.  If you follow the 
diagram for most of those adapters, the result will be the same as using 
a mono plug - the ring will still be connected to the sleeve of the mono 
plug.

The only real answer is to change the mono plug of your ICOM SP 20 to a 
stereo plug with only the tip and the sleeve connected (No connection to 
the ring).

73,
Don W3FPR
