[Elecraft] K3 IO1 Error Message

[Tony Fegan VE3QF]

Hi Stewart,

	I have been visited by the same bug. This just started a few weeks ago. 
My errors are quite consistant. The power on error list shows the following:
BP1
LPF
IO3
IF1
XV3
BP2
AT3
PA1
	I have been monitoring the front panel temperature and the problem 
seems to happen only when the temperature is below about 32 deg. 
Sometimes there are several days between errors. If I leave the rig on 
until the temperature is above 32 deg. then I get a clean power up. My 
13.8V supply is a Kenwood PS-50 which is normally left on.
	On a few occaisions I have switched the DC supply off after a prolonged 
sequence of errors and so far the power on errors have ceased either on 
the first or usually the second K3 power on. This leads me to believe 
that it could be a power off housekeeping problem. Not really enough 
evidence yet. No errors for a couple of days.
	Thankfully it is not a show stopper. By the way my serial number is 
00137 (quite close to yours) factory built. This is my first problem 
(not counting broken knobs!).
	I will gather some more evidence before contacting support.
