I posted this problem several months ago and never received an answer from
anyone on it.  

My K2 (and I've talked with several other K2 owners with the same problem),
Serial #4338, will not always detect a hand key properly -- Autodetect is
turned on in the menu - and I am using 2 1N914 diodes between the hand key
contacts and the dot and dash inputs to the K2.  The keypaddles function
properly at all times, but when using the hand key, at random times, a key
down on the hand key produces the same results as a paddle press - namely
automatic dots or dashes.  This has proved to be a nasty problem, especially
in a contest when needing to rapidly slow down to re-send information.  You
get part way through the exchange and the characters get all messed up due
to the aforementioned erratic action.  

Is there any known fix for this problem????

Would appreciate any information available on the subject.
