Hi Mike and list,

Your e-mail caused me to look at my Z3801A.  It looks like mine has lost 
its mind.  EFC was pretty stable until about 93 hours ago and then just 
started nose-diving...

Note - I've tried chasing down the reason for the Self Test error, was 
never able to determine what was causing it.  It's been that way for at 
least 4 years now and working fine, so I don't think that the self test 
fail has anything to do with the recent issues...

Any guesses from the folks on the list?

Thanks much and 73,
Ben, kd5byb
