Drake R4B calibrator

This small pcb fits inside the Drake R4B and replaces the original calibrator board. You have your choice of either 100, 50, or 25 KHz markers. Best of all, you can have those markers pulse so you can find it on a busy band.
Drake fan controller

Although not just for the Drake radios, this simple fan control circuit will help keep the heat from cooking these old rigs.
