[Elecraft] K3 - Speaker/headphone problem

[N2TK, Tony]

Hi Dave,
Tnx for the info, but I don't think that is my problem. I have been using a
stereo plug in the K3 for over a year without a problem. And my external
speaker and internal speaker work fine if I turn on SPKR + PH. I just can't
get the internal or external speaker to work when there is no headphones
plugged in and SPKR + PH is OFF.
This is one of those problems where the night before it was fine and the
next morning it was not working. Power had not been turned off. In fact the
only time I normally turn off power is when I reboot after upgrading the
firmware.

73,
N2TK, Tony

Tony,

Same thing happened to me when I plugged my Kenwood mono speaker into the 
stereo speaker jack on the back of the K3.  I did this without thinking from

the front of the radio when I was rearranging equipment in the shack.  The 
speaker worked for a couple of days until the audio output transistor 
failed.  I could then only hear audio from the headphones.  I had to send my

K3 back to Elecraft in order to replace the audio output transistor.  It was

under warranty so they repaired it for free.  While the rig was in the shop,

I had them add the sub RX, digital voice recorder, and the IF Out interface.

So they came out okay on the deal.

But I learned my lesson -- do not plug a mono speaker into the stereo 
receptacle.  It is clearly labeled as Stereo on the back, but you have to be

looking at it from that direction!  Even the manual shows it as stereo.

Dave, N4QS
