[Elecraft] Prolly a dumb mistake... no internal speaker output

One thing to remember, when you change the spkr+ph  yes/no  there is a 
DELAY (in one direction) for several seconds as this is a soft-switch to 
the BRAIN.
So wait a bit when you test this!
Also, Try the PH.R + -- in the other setting and then test the above 
again, waiting for the delay.
**In ANY case; *IF* you do in fact have rear SPKRS jack audio, and you 
unplug them, the internal speaker should come on!
If not, there is most likely a physical problem, like bad 
speaker/wire/spkr jack etc. The internal speaker gets it's audio 
directly from J18 (rear spkrs) jack thru L3 (could be open) on the KIO3B 
Audio board.
An aside, if anyone is searching audio problems;  If you have had the 
Front Panel off, I have seen the J/P50 plug on the DSP to RF board *UP* 
a row of pins! This totally fubars up all the rear audio!! (you can look 
down in there with the top off and some magnification to check).
