[hpsdr] Speaker output from mercury

[Jim Sanford]

Please forgive my incompleteness:  The 10 watt amps I have come from 
"parts-express", an audiophile DIY source that has served me well in 
many ways.  They were not expensive, either.

I'm sure there are other sources out there.

Good luck and 73,

Jim
