Though the workshops are generally geared towards teens, we encourage participants of all ages to share our space on 10/15, and look forward to a thoughtful intergenerational discussion.

Fellow time-nuts, Anyone who has tried to calibrate the PPS input and PPS output interpolators of the PRS-10? The output calibration seems pretty easy to do, just a TIC to measure the PPS to 10 MHz and then sweep through the output delay values to cover a little more than the 400 ns range.

If you divide the 10 MHz by 5, then mix the resulting 2 MHz back with the 10, you'll get mostly 12 and 8 MHz. Double that result to get mostly 24 and 16 MHz, then filter the 16 MHz out with as fancy a filter as necessary. 16 MHz is a very common crystal frequency, so you could do that for filtering, or even make a ladder filter with a bunch of them.

A few DARK-EYED JUNCOS and HOUSE FINCHES continue to visit bird feeders around town, and small flocks of SNOW BUNTINGS were reported from rural areas over the past week. Thank you - and Good Birding in the New Year!

If the instrument was provided with a countersunk hole for a #6 screw it was not always possible to upsize to a #8 or #10. Quite often the #6 screw would twist off unless you drilled out the pilot hole oversize. In addition you had to countersink the edge of the pilot hole or the gel coat would chip.
