. Unrelated, anyone aware of a hardware (IC) counter which counts in a (local-bitflip) Gray code, so it can track a very fast (integrated?) oscillator without dropping cycles? P.S. Thanks for pointing me towards GPSDOs. Any European/German local alternatives to the Trimble Thunderbolt? -- Eugen* Leitl
