I blew the switching FET with about 50 ma of current (12 volts) from a DownEast Microwave transverter. Elecraft says it should have handled it, but anyway, FWIW. The FET has been replaced, and an intermediate switching transistor installed in the switchbox for the several transverters. Now switching 1 or 2 ma, hope that holds! 73 - Jim K8MR ____________________________________ From: [email protected] To: [email protected] Sent: 3/12/2013 12:07:26 P.M. Eastern Daylight Time Subj: [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?
