[Elecraft] K2 key-down issue

[Tyler Barnett]

I've got an early K2 SN 2608, with 2 problems....and Field Day is almost here :-(

I have a key plugged into the rear key jack, and the Menu set to "Paddle -> Hand Key".
When I key the radio, it stays key-down until I unplug the cable from the K2.
I've borrowed another K2, and using the same cable it works fine.  
Any ideas on this?

Another minor problem is that it doesn't mute the speaker when plugging in the headphones.
I can live with this, but the key-down issue is a killer.

Thanks!  Tyler N4TY
