Hi Art,
I use an Orion II and a Delta II with a Centurion. I'd recommend that
mod, which can be done within less than 5 minutes.
Happy holidays!

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.
Art, KØRO
