| - | + | Note for older 422 Centurion amp owners: Using an older Centurion with the newest Ten-Tec HF transceivers - Pegasus, Jupiter, and Orion - may require a small modification to the QSK board in older Centurion amps for proper QSK CW keying. Short diode D2 (red diode, 1N4148, next to Q1) with a jumper wire. The current 422B does not require this modification.
