Maybe I've finally found a use for the round hole with 8 pins located just to the left of the headphone jack. This would be a splendid home for a nice bright red LED split indicator. Maybe I could use 2 of the pins to power the light. This is probably what the designer had in mind. I wonder

Hi Rick: IF you attempt this (though I suspect you're kidding), be aware that the LED specified for the SPLIT/RIT indicator is a Hi-Eff (e.g. very low current) device. If you (or anyone else) use a regular LED, you will have to add a driver transistor in order to allow the LED to draw more

Folks, I just added a hi-current LED to my K2 as a SPLIT/RIT/XIT indicator. Adding the emitter follower transistor was a cinch. I used a 2N2907 PNP transistor, connected the base where the cathode of the lo-cur LED would have been, connected the collector where the anode of the lo-cur LED was
