Lost Speaker Output on K3 with no phones plugged in

WB4SON
After working just fine (no phones plugged in==> speaker on, phones plugged
in ==> speaker cuts off), I just removed my headphones and have no speaker
output.

I immediately checked the SPKR+PH setting, usually set to "no", and
adjusted it to "yes".  At that point I have output from the speakers.  So
there doesn't appear to be anything wrong in the audio chain.

I presume whatever mechanical part of the PHONES jack that senses the
headphones are plugged in has failed.  But I thought I would check to see
if anyone had similar issues with a different cause in the past?

My K3 is about 2 years old at this point, so fairly "low mileage"

Bob,

Try inserting the headphone plug and removing it several times (with the
SPKR+ PH menu set to NO).
The wiping action of the contacts on the headphone jack may restore
proper speaker response.

Further explanation - if you normally use headphones, oxidation can
occur on the contact points of the headphone jack.  Insertion and
removal of the headphone plug should create a 'wiping' action on the
contacts that should wipe away that oxidation.  It may take several
"wipes" to remove the oxidation, so exercise it a bit before declaring
that the headphone jack is "dead".
