[Elecraft] K2 driving KPA500 / KAT500 - one small error in prior post

[Michael Blake]

Dave, while not a K2 I do drive my KPA500 with my KX3 and get about 350 watts output on 80 & 40.  I have not used the KPA500 with the KX3 on the higher bands.  

The KX3 has 15 watts output.

There must be an amplifier keying line somewhere in the K2 circuitry, since it can key a KPA500 [should have read KPA100] in the two-box "twins" configuration; but there is no mechanical output for it.  Anyone done this who can help with ideas?
