[time-nuts] Ancient OCXO in scope calibrator.

2008-09-07 Thread David C. Partridge
I'm having some problems with an ancient Bulova OCXO in a Tektronix 184 'scope calibrator. This is an crystal mounted on an octal valve base with a heater winding wrapped round it, and a common or garden variety thermostat which is supposed to switch at 75 celsius. I've not measured the

Beware, programmers have turned to screaming, blithering idiots with bits of their brains oozing out all of their orifices just by glancing at that page. Worse than writing a Web Server in the language BF? The B stands for Brain, and I'm not going to put the F on a family oriented list

G. email failure, maybe a repeat: I have one of those oscillators in a tek 184 that I do not use anymore. Those calibrators are really cool, I used one for a long time when I first started tinkering. If you need it, you can have the oscillator. ([EMAIL PROTECTED]) Good luck! Still needed HP

Dave Need a few more circuit details. The crystal current wont be very high unless their are other components connected to G1. Bruce The anode G1 capacitance is about 10fF so with 25V rms at the anode, the crystal current would be around 16uA if the circuit relies on feedback via

Hi all, For those of you mainly in Australia and New Zealand you may remember VNG - the now long departed short wave Australian Time Signal service. These words will be familiar: This is VNG, Lyndhurst, Victoria, Australia on 4.5, 7.5 or 12 MHz. VNG is a standard frequency and time signal
