[Elecraft] External Speakers for K3

[Pete Lascell]

I too have used the 2-way radio speakers for more than 30 years and 
originally did with my K3.  But after going thru the junk stach again a 
discovered I had a pair of amplified speakers (not cheap) used with Radio 
Dispatch Consoles as SELECT and UN-SELECT audio channels.  They contain ~ 6 
watt audio amp and a substancial speaker, power by 12 volts.  So I now have 
plenty of audio and with the speakers spaced about 6 feet apart there is 
noticable separation, and the AFX function is great when desired.

With the extra amplification and volume controls I can set the K3 volume 
control for hot earphone level, yet turn down the external speaker levels.

I know it is overkill, but need to put the junk in use, or give it away :-)
