My Orion II does exactly that occasionally, and I have not determined
any specific cause.
I installed a new battery and I have changed all the electrolytic caps
on the A9 board, without significantly changing what happens or how
often it occurs.
I initially believed that it had something to do with variation of the
voltage supplied to the transceiver during the startup process, however
even though my Orion II is now on battery backup via a Super PowerGate
the problem still occurs, although it appears to occur much less often
now.
John Henry has been made aware of this specific malfunction and I think
that just possibly a fix may still be forthcoming, whether in some
firmware change that affects bootup or via some hardware mod.
I am sorry I can't offer a remedy, other than to tell you what I did,
and that you aren't the only one who has this happen.
