Magnus, Thanks for the manual pointer! A quick scan doesn't offer me much insight to what the mod might be for (likely have to open it up as you suggest). The basic unit gives you the option of phase-locking the internal standard osc to WWVB with an output at .1, 1, 5, or 10 MHz , and you can compare either the internal or an external oscillator to WWVB and chart the results over a variable time period.
Given the time-nuts mailing list audience my guess is that in practice it would likely be used with an external reference source to monitor WWVB deviations, instead of the other way around... It was fun to see the effect of the "sun flares" noise on the sample chart recordings in the manual!
