[Elecraft] Lost speaker audio in K2

[David Lankshear]

The headphone jack seems to be the K2's achilles heel, Steve.  It's something that crops up on here from time to time.

After completing my K2 I had no speaker audio but headphones were OK, so had to swap out the headphone jack.  Elecraft were like lightning sending a replacement all the way across the pond.

My friend's K2 had very low speaker volume and a replacement headphone jack fixed that too!

Before pulling it apart, though, do check you have the speaker connector plugged into the 2-pin connector on the main RF board and not the 2-pin location with the same designator on the control board.  Also, check your speaker from that point with an ohm-meter, just to be absolutely certain it's not a problem with the extension speaker jack.

PS.  Do like I did and invest in an additional spare headphone jack.  That way, Murphy's law will be defeated and it will never ever give you any more trouble.  Meanwhile, the spare jack will slowly gather dust HI!
