[Elecraft] wiring motorola amplified speaker for K2

[Charles Bland]

Tim,

These speakers were designed to be driven by balanced audio. That's why the 
audio input names are a bit unusual. The squelch line was designed to mute the 
speaker, as was pointed-out in an earlier posting.

I have had some trouble with mine being sensitive to RFI. I haven't got it 
licked yet, but I'm still trying.
