- Dynamoters...you forgot the true dinosaurs of High Voltage. The proper
- technique when using dynamotor powered ARC-5 transmitters was to press
- the mike key and wait a second or so until the motor was up to speed.
- It really brings back memories of adding another battery to the car's
- electrical system to bring the voltage up to 24 volts for the dynamoters.
