Marco, I use a LM7805 voltage regulator to provide inhibit voltage to my K3 (accessory pin-7). Since I use a sequencer it defeats the inhibit voltage to enable transmit by grounding the voltage regulator thru a 1K current limiting resistor. But the simple voltage divider concept looks fine

[Elecraft] Microham Station Master Inhibit -> K3 ?

Hello, I'm optimizing the shack setup and taking a more careful look at hot switching; Antenna switching is managed through a couple of Microham Station Masters, which provide an Inhibit Output as cinch connector. So Inhibit will be set during any Antenna transtition to protect the switches, th
