[Elecraft] Need a PTT from my K2/100.

[John Regner]

I just purchased a new amp (HLA 305) and began hooking up amp. Read the
instructions in the manual and it stated that if there was no PTT, to
change the VOX setting to "on" which I did. I attempted to TX and there is
no response from the amp. I called DX Engineering and was told that the PTT
must be used to trigger the amp.
OK - so where does one find the PTT from a K2/100?
