Just curious what the MINIMUM output of a 40 meter OHR-100A is with the pot turned all the way down. I can’t find that info anywhere online. I realize it may vary from radio to radio. Would you expect
it to key properly at minimum power?
The minimum power is 0.00W and it does not depend on the band. On all OHR 100A transceivers, the
power output is continuously variable from zero to full power. The power control is actually the bias on the driver, so the transmitter will key properly regardless of output power setting. The power output control is a 100 ohm trim pot accessible from the rear of the radio. Full power is at minimum resistance on the emitter of the driver transistor.
