[time-nuts] Z3805A: How correct a 1024 week date error?

[Bob Camp]

Hi

The unit will do just fine as a frequency / pps standard with the date error. 

I believe the answer is a re-flash of the firmware in the GPS module. The first step there is to figure out which module you have. If it’s a Motorola you may be in luck. If it’s a Furono, you may be out of luck.

Does anyone know how to spring the unit from it's historical bonds and get it to read the current date.  I have tried commands (via GPSCon) to do a factory reset and to enter the date manually, but without success.  Any experience would be appreciated.  Jim Robbins, N1JR
