PSL1V0C-0.82

My 6500 just threw the above error while I was away doing something totally unrelated. Neither normal power down/up nor factory reset would clear it. Unplugged the power for 5 mins and the fault went away.

What does it mean?

Gerald previously posted "The message says that your 1V power supply is running low at 0.92V. When the voltage goes below 0.92V, the supervisory processor will shut down the CPU and reports that error. " but his examples used a power threshold of 0.92V. If it returns, especially if you are certain the radio's external power didn't vary or drop you might put a Help Ticket in. 73 Steve K9ZW

Thanks for that Steve. I'd half guessed it meant something like that but couldn't see what might be the cause, as the radio was just sitting there and clearly had power. My controller monitors the before and after fuse voltages and the last values the radio sent before it crashed were around the 13V mark. Of course the radio only updates those voltages every couple of seconds or so, so I might have missed a spike.

The radio has been fine since I did the unplugging thing, so it's just one of those mysteries I guess.
