[time-nuts] Electronic Research Co. Precision Crystal Oscillator.

Hi. A little while ago, I acquired an ERC EROS - 800-MIL-2  10MHz 24V powered OCXO, dated 95-23. Well, it seems to work, and comparing with the trusty Thunderbolt, once warmed up and viewed on a dual channel 'scope, where one channel is triggered from one source, the drift relative to each other

Probably Nickle Metal Hydrite (NiMh.) Much more electrical capacity in the same size cell as older NiCd's.  No memory effect, and currently available in all the common cell sizes, with or without tag's.   The only thing you might have to do, if the charger is time based, is alter the timer so you

Take a look at Andy Talbot's page at... http://www.g4jnt.com/Synthesizers.htm Lots of good options there for that sort of thing. 73. Dave G0WBX. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to

Re: [time-nuts] sine to square wave circuits

Silly question, and forgive my ignorance. But, why is a simple two transistor discrete Schmitt trigger circuit no good for this purpose? 10MHz is not a problem, so what is bad about it? Regards. Dave G8KBV. ___ time-nuts mailing list --

[time-nuts] [OT] Re: Bad TBolt Crashing LH?

Yep, Prolific got badly hit by the counterfeiters. So, they depreciated the use of all the early generation chip-sets (even legit ones!) and had MS push out updated drivers to enforce that. That's why it "appears" to be a Windows update problem that stops many older Prolific based adapters

Re: [time-nuts] Bad TBolt Crashing LH?

Windows or ??? If Windows, check the OS's power settings, and make sure that it's not sending peripherals to sleep after a period of "Inactivity" (judged by a lack of keyboard/mouse activity, NOT the existence of any running programs, or screen updates.) Regards. Dave B. On 29/08/17 17:00,

Re: [time-nuts] Trimble Thunderbolt no longer determines the correct date

Interesting. What about NTPD implementations, when using a TB as the reference time source? Does that handle the week count roll over as well? If that was added, from what version? I suspect I may have some updating to do! I use a TB as a frequency ref' and local NTP/NTPD server reference.

Didn’t someone say a while back, that there appeared to be "other data" present on the transmission, but didn't know what it was, or used for... Or did I imagine it.? Maybe that's why they keep it going? 73. Dave G0WBX. On 11/05/17 05:15, time-nuts-requ...@febo.com wrote: > Message: 5 >
