Re: [time-nuts] Accuracy results with Trimble Thunderbolt?

Antenna mask of zero degrees is actually NOT good.  You get satellites going in and out of your antenna's view too often (because satellite can pop in and out of horizon, and other obstructions), cause switches in satellite used, and that contribute to fluctuations.  10 to 20 degree, in most

I would be concerned the xtal has drifted so far it can’t be adjusted to 5 MHz any more. My 103AR has such a problem. On Fri, Mar 20, 2020 at 12:17 PM Taka Kamiya via time-nuts < time-nuts@lists.febo.com> wrote: > I saw this one. > What scares me is that the seller appears to be competent in

I hope you all don't mind a novice-level question, but I'd be interested in any feedback on what I'm seeing with the accuracy of the 10 MHz signal out on my Trimble Thunderbolt. I bought the Thunderbolt last year used on eBay, and it appears to be of about 2001 vintage. Most recently it's

I saw this one. What scares me is that the seller appears to be competent in testing his frequency counter, oscilloscope plugin, and other equipment, but on this one he says, "not sure how to operate".  My alarm went off and I didn't bid. --- (Mr.) Taka

Hi I’m guessing that it is a dewar based OCXO. If so, the *big* question is: Can the boys at UPS / Fed Ex / DHL / USPS (your pick) get it to you without cracking the glass bottle? I’ve had reasonable success at shipping them ( = dewar based OCXO’s not HP106’s) in, but not 100% success.
