[Elecraft] K3: Headphone Jack hardware?

[Jim McDonald]

I leave headphones and a microphone plugged into the front panel jacks and a headset plugged into the rear jacks.  I turn the speakers on and off with the macro:

MN097;UP;MN255;

No wear and tear on the jacks.

I have macros set up in my K-Pod, DXLab's Commander module, and VA2FSQ's Win4K3Suite, though only one would be sufficient!

Hi Martin - My K3 is on its second headphone jack, due to symptoms like yours.  Recently it started doing this again, but I was inside the radio for another issue and reseated some boards (including KIO3 if I remember
correctly) and it stopped happening.  You might look into that before you replace hardware.
