content: I mentioned I fitted new batteries and have tested the life while measuring a 10MHz signal. The results are just over 37 hours continuous use. Brill

content: Quote from: bd139 on October 27, 2019, 11:31:11 pmI agree.I am thankful for GPS. Any system that can pinpoint my location from the distances involved with time critical algorithms is going to be well good enough for me. I am also thankful for the development of associated technology to the point where it is rather good value.Volts are a different kettle of fish entirely.

content: Quote from: Brumby on October 28, 2019, 01:19:47 amGPS is wonderful but a bit easy to jam if you have something too critical; does not apply for the home-lab, but for critical infrastructure one needs serious holdover. Work makes me something of a time-nut, since we're dependent on working IEEE1588-2008 PTP for audio networking.I've got a Meinberg GPS-equipped NTP server at home with 10MHz and 1PPS outputs. It is an under-utilized resource in my setup.The TTi counter is interesting, but I've got my eyes on a Philips, for nostalgic reasons.

One of few TE manufacturers with Swedish presence. Today, probably the most known is FLIR Systems.
