I have just found out how to get sidereal time from Lady Heather. (You put t=GMST in the command line, or alias target line, and the Lady comes up in Sidereal Time, ticking away in Sidereal seconds.) (Also you can get LMST, LAST or GAST.) Now, as a time nut, I have questions. How is a leap second

Not sure about that, if you look at the frequency plot after ~20 minutes in moving air the frequency was still extremely close to 10.00MHz.. to within <1E-011 of 10MHz. This is a free-running 10811. Compare that to the plot of the OCXO I had sent out some hours ago when it was running s

Re: [time-nuts] noisy varactor diodes

But putting the diodes in series should increase the noise. They are noncorrelated, so I would say increase the noise in a RMS fashion. HP has made at least one radio with switched varactors in the prefilter. They made a SIGINT rack for I presume three letter agencies, though it was in the cat

Paralleling devices reduces noise. Why do you think otherwise? Noise will be reduced by the square root of the number of devices you parallel. -Original Message- From: cdel...@juno.com Sender: time-nuts-boun...@febo.com Date: Wed, 19 Dec 2012 14:43:02 To: Reply-To: Discussion of precise

[time-nuts] noisy varactor diodes

The HP sceme in the patent refers to an array of series and parallel diodes to reduce noise. Just paralleling them does not reduce the noise! The 4 paralleled in the 5065 are to give enough phase deviation for the low modulation level applied. (150mv) The symptom was a fluctuating 2nd harmonic
