[Elecraft] [K3] - Possible defect with REV button?

[aa4lr at mac.com]

I have two K3s. When I received SN 70xx ten years ago, I operated for two years without the KRX3. I became adept and figuring out split listening frequencies by pressing the REV button and tuning around. When I got the KRX3, things became much easier and I didn’t have to do any of that fancy dance holding the REV button and tuning the knob.

In the last year, I brought SN 89xx, and it does not have the KRX3. When I’m using it at my other QTH, I notice that the old trick holding the REV button doesn’t always work.

Holding REV swaps VFO A and B temporarily, and they switch back as soon as you let go fo the REV button. 

It will work at first. But, sometimes, after holding REV for a few seconds, the word “END” will appear on the display, and the radio will sometimes switch VFO A and B back, as if I released the button, but other times it will leave VFO A and B switched. 

There doesn’t seem to be any rhyme or reason to it. It just happens “sometimes”.

Has anyone else observed this? Is there some obscure configuration setting that is causing this behavior? I couldn’t find one.
