You might try installing a "soft key" kit in the amp if the voltage and
current requirements may be a bit high for the KX3.

Subject: [Elecraft] KX3 Relay Control For Desktop Amplifiers
Most common desktop amps have a relay circuit that requires a transceiver
to short 12 VDC at 100 ma to key the amplifier on.
In the KX3 specs, the maximum amp relay current is stated to be 100 ma.
Has anyone keyed a desktop amp directly with a KX3 or is it recommended to
use an intermediate external relay circuit?
Thanks,
W9DBR
