[Elecraft] External Speakers for K3

[Walter Underwood]

Oops, mine is a Realistic Minimus 7. Later, they were named the Optimus Pro 7. You can find a more full history of these nice little speakers here: http://www.angelfire.com/vt/audio/minimus.html

You may be able to find something similar if you shop around a bit.  These are non-amplified speakers and work quite well, no worries about RF feedback or other problems that sometimes occur with amplified varieties, and the K3 has more than adequate audio to drive these high efficiency speakers.

For those who do SWLing, the full range speakers may be better for those users than communications speakers.

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.
