The dopest hackers on the planet. See below, finally we can calibrate out the expected timebase drift! Thanks kirill_ka. We all owe you one. |

I'll give this a try shortly! And we get to look forward to this problem again in 2 years (got a patch ready for the 2019 rollover?). ;) Thanks, Pat |

So it's thrown backwards not the same time GPS week count wraps. I.e. it should work for another 20 years. In 2038 old *NIX stuff will die anyway :) |

Just tested it, and it worked great! For anyone keeping track, I let the unit warm up for 15 minutes (with the GPS antenna connected), like the instructions say. From the calibration, my DAC setting went from 2162 (factory) to 2121... so a similar change to what technogeeky had. I left it on the adjustment screen and clicked the repeat button a few times over the last 20 minutes, and it has continued to climb (it's up to 2190 now). I'm gonna leave it on overnight and check it in the morning. Thanks again! Pat |

And, a final update... after letting it run overnight, it seems to have landed at a DAC setting of 2223 (it bounces around +/- a few values, but hasn't drifted over the last 45 minutes). Pat |
