Hal, I suppose your opinion is correct. A friend has found the same problem with an HPZ3016A GPSDO. The solution was to resetting the internal counter inside the Motorola GPS module. To do this , the friend has removed the GPS module and communicate using his proper serial port to reset the internal counter. I have not some more details about the operation, but if request I can ask him. Luciano

There is a 10 bit field for the week number in the data from the satellites. After you decode the date/time you have to compare what you get with a magic date. The magic date is typically the time the software is compiled or a constant in the code that is whenever the programmer last updated it. If the GPS date is earlier, add 1024 weeks. Repeat if necessary. The simple solution is to fix the software driving the display, It's 2 or 3 lines of code in the right place. If you can't do that, you might be able to insert something between the TBolt and the display that will fixup that slot. -- These are my opinions.
