Hi,

I've had my unit off and in the closet for quite some time, then played
around with it yesterday.  :GPS:INIT:DATE wasn't taking 2015,09,28 and
kept returning E-222 "data out of range" and was stuck in 1996.  A few
power cycles and it got to 2007.  A few more power cycles and finally it
got it right.

Is this that 1025 week epoch thing?

Anyway, I was wondering about freshening the firmware if possible before
I go delving into the embedded project of adding on an NTP and PTP
grandmaster time server with this as the source.

Is there newer firmware?  If so, where?  Updating the GPS board is
probably swapping EPROMs?

Thanks, in advance.
