CW problem

[Elecraft mailing list]

I am trying to run down a CW transmit problem on my K3s. Anytime I change the mode from LSB or USB on any band to CW it starts to send a “dit” without stopping and I have to halt it by restoring the configuration. This does fix it until I try to switch to CW again; and then, the same story.

I recently removed a Kent (straight key plug) and the problem showed up. Any ideas?

John, I think you may have won the Unique Problem Award with that one. Good
luck (sorry).

Good morning

Do you have any external programs connected via CAT control?

John,

The recommended troubleshooting steps in cases like this is to remove
everything from the K3 except the power cable and the coax to a dummy load.

With that done, does the problem still appear - if so contact
[hidden email].

If it does not appear, then plug things back in one at a time to see
which external device is causing the problem.

John,Re:  "Anytime I change the mode from LSB or USB on any band to CW it starts to send a “dit” without stopping..."Take a look at the plug and jack.  Be sure there is no damage to the jack, and that none of the plug was left behind in the jack.  That happened to me once on a keyboard.  A part of the plug's barrel broke off and just happened to short the tip to the shield.  It was difficult to see, too. It's a long shot, and may not be what happened in your case, but the symptoms are correct.Mark,KE6BB
