[Elecraft] Strange speaker problem

[Ralph Parker]

Could it be this? I saved this item from a KE7X post. Worked for a 
friend with a similar mystery problem -
VE7XF

At one point Elecraft had to change the switch that cuts out speaker 
audio when the phones are plugged in so there is a setting in 
CONFIG:SPRK+PH that selects one of two action polarities.

Tapping the 1 key toggles between PH.R SW- (inverted) and PH.R SW+. Try 
changing that.
