Re: [time-nuts] RCC 8000

Hi, I am looking a description/manual for Radio Clock? type RCC 8000 receiver... assume it is tuned ?60kHz . and should like to convert? to DCF 77..every advise is appreciated. Rgds, Ernie -Original Message- From: Ulrich Bangert [EMAIL PROTECTED] To: 'Discussion of precise

Hi Rob, Yes , I tried RadioClocks UK but no helping hand...they offered if I ship the unit back to the factory, ??? they give a price for the conversion./ assume to expensive /... ??? I am living about 25km from DCF77 in Germany, so believe the receiver part is not a big deal,

Re: [time-nuts] xtal oscillator phase noise

Henk Two things will dominate if you want such a low phase noise spec.:- the loaded Q of the oscillator circuit, and the flicker corner frequency of the sustaining amplifier transistor. To get a high loaded Q you need a crystal with a high unloaded Q - maybe 100 000 or more - this isn't

Re: [time-nuts] xtal oscillator phase noise

AFAIK, in a crystal oscillator specifically (not oscillators in general), the oscillator transistor has almost nothing to do with either close in or far out phase noise. The close in phase noise is typically limited by the crystal's intrinsic noise and the far out phase noise is limited by the

[time-nuts] Manual Needed, TrueTime 800 series

Fellow clock-tickers, I have need of the equipment manual for a TrueTime 800 series TCG. More specifically, model 814-319-1. Worst case, I'll try contacting Symmetricom, but I'm not holding my breath on that one. Thanks. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner

Hi Ronald: Not yet. Right now I'm having fun with old DC motors and Flashlights. http://www.prc68.com/I/EM_ToyEngine.shtml http://www.prc68.com/I/Gilbert-Motor.shtml http://www.prc68.com/I/Weeden-El-Motor.shtml http://www.prc68.com/I/FlashlightPat.shtml Have Fun, Brooke Clarke

Re: [time-nuts] RCC 8000

Hi Nigel, Thanks for the offer, well I am not in a hurry, just take your time.I have many other project to go on. About 10-15years ago I tried to copy MFS but due to the close proximity of DCF I was unable to copy maybe I did not pay attention to the selective active antenna and
