I purchased a Centurion that was being used with an Orion. The previous owner
had made the mod recommended by Ten-Tec:
"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."
I have an Omni VI. Should I undo that modification, or is it benign? Could it
be the cause of the buzzing I detect at the relay?
Any thoughts are appreciated.
