[Elecraft] Use of external speakers/amp

[Edward Dickinson, III]

I don't know who is loading what in this response to a query for improved
sound.  Rick's question indicates nothing unreasonable or unachievable.
What amateur radio receiver cannot benefit from improvements to the audio
chain outside of the equipment itself?  Additionally, he's not asking that
anyone broaden, or otherwise change their TX audio.

  This is a loaded question, like "when did you stop beating your wife?" 
It implies that there is something wrong with the K3 audio.

I have used both the K2 and K3 for some time, and as far as I can tell, 
there is nothing wrong in this department. There is more than enough 
gain to blast one out of the room or to fry one's ears using headphones, 
and the range depends in the normal way on the bandpass used in the 
receiver.

Voice spectrum is scarce, and there is little excuse for using more of 
this resource than is necessary for effective communication. I think 
that almost all SSB operators realize the need and even the 
effectiveness and utility of band-limiting their TX. A quick look on the 
P3 or some other spectrum display will convince one of this. We should 
be thankful that people don't insist on transmitting the full range of 
audio frequencies that make up the human voice.

Since what goes in dictates what comes out, it is unrealistic to hope 
for broadcast quality reception. Perhaps more careful attention to 
tuning SSB signals is needed...it does not take much offset to replace 
the human with Donald Duck.
