Re: [time-nuts] re low noise regulators

Gentlemen, over the last years I have been confronted with numerous nonsense and rubbish technical ideas as part of my job. Over the years I came to the conclusion that just for the sake of clarity it MUST be allowed to call them nonsense and rubbish without applying any political or other

[time-nuts] newbie questions

Hi, My name's Jason, and I must admit to being drawn in by the fascinating article on Wired. ( if that makes me a dork, so be it!) As a kid I thought it was neat to try and set my watches and clocks to WWV from the cheap, crummy 1960's JC-penny all-band receiver , but was always annoyed that the

Hi Dave: The HP 114 is a 1 PPS trigger generator with offset and was made for use with WWV, see: http://www.prc68.com/I/TF_rack.html The audio from an HF receiver is fed to the V input on the scope and you can adjust the sweep speed as fast as propagation will allow. The 114 time offset moves

Re: [time-nuts] Upgrading possibilities for more accurate, precise stable time system

Hi Ronald: Have a look at the different time transfer methods at: http://www.prc68.com/I/timefreq.shtml#TT Since these involve receiving a signal from a transmitter you need to have a way to know which signals you can get in your building. For example LORAN-C and WWVB are low frequency

Re: [time-nuts] re low noise regulators

I think the issue with the series resistor is that the oven current is temperature dependant, so the drop through the 2 ohm resistor is temperature dependant too, regardless of the tolerance or stability of the resistor itself. As long as the current/temperature curve of the oven is predictable,
