[Elecraft] K2 relay circuit?

[Joe-aa4nn]

Have you tried the PA Key Out line to your amp??
Or maybe the PA Key Out is only on the KPA100 module
and not on the basic K2.

Does any have a switching circuit for a K2 that will activate the relay in 
an amplifier? My 11-year-old Kenwood is in for a repair, and it may be a 
while before it's back in the shack. In the meantime, I'm driving an 
Ameritron ALS-500M solid state amplifier with 7 watts from my K2.
That works well but requires me to key the amp relay (I use a pushbutton on 
a cord) as I key the K2 with the mic's PTT switch.
The voltage on the amp keying line is 10 V DC, and the current when keying 
the amp is 120 mah.

K2 # 5120. Sometime in the six few months I'll build the K2 100-watt 
internal amp.
