Amplifier sequencer

Having interfaced a number of transverters into radio systems I’ve learned it’s always good to use a sequencer. Sequencers are intended to be used with any lash-up that requires separate sequenced switching of circuits to control pre-amps, relays, transmitters, and power amps. This will prevent transmitting with a high powered amplifier into a coax relay … [Read more…]
