I have an old PT-2500A with a 120 volt relay. Modern radios don't like such a high voltage on their PTT circuit. Can someone point me to a circuit that will allow control of the 120 volt PTT relay with something in the 12-24 volt range ? Seems like it should be pretty simple with a transistor that can handle 120 volts collector to emitter, but I would rather have a tried-and-true circuit so I don't screw something up. Thanks and 73, Steve, N2IC _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
