if this happens only when you run high power, suspect rf feedback affection the orion's control logic and circuitry.  i have a high rf shack, and as i increase the output power, usually the led's on the front panel start to randomly flicker.  if i keep pushing the power up, i'll lock up the orion in a state requiring a power cycle for recovery.  how much rf is required varies from band to band.  it doesn't matter which firmware i am running.
