Tom, Right on the pps and frequency. I should have been far more clear date and time. I fired up my 3801 and it locked up just fine. Need to check its message to see whats its putting out. I will say that I added 2 AA batteries that seem to be lasting for several years easily and they keep the memory in the GPS engine going and maybe that keeps the date and time correct so that once you have corrected the date and time maybe it sticks. Regards Paul.
