Re: [time-nuts] OT: Eagle PC CAD now Autodesk, $500/year

Hi Fusion 360 has the same sort of “slurp it up” and “net connection” requirements. Anything you do is (at least potentially) not exclusively yours. Fine for a basement. As you point out a bit nuts for any corporation. My guess is that there is or will be some sort of corporate server

Re: [time-nuts] 10MHz to 25MHz

Hi There are several other materials that you can make crystal resonators out of that are piezo electric. Some of them can give you much higher Q. This comes with a whole raft of other issues. Langesite is one of the more common materials you see people playing with. It is common enough that

I'd say 80% of the outside design work I do have little ditties in the contracts that say NO development to be done on net connected systems. New Eagle requires a net connection to keep working. Also the EULA seems to say they can slurp your designs at will and ship them off to who knows

Re: [time-nuts] 10MHz to 25MHz

once upon the time there was an other crystal material -- NOT quartz ! -- the Russian came up with it, perhaps Bernd [Neubig] remembers on that, what happened to that story? that crystal could be run at higher drive level, therefore it would be possible to make some better oscillators 73

Re: [time-nuts] Thunderbolt Harmonics

I'm trying to be gentle, Rhys. :) I work with these issues every day at work. Here are a few more comments. I assume you have the preamplifier in the spectrum analyzer turned off. The term "X harmonic" (such as 2nd or 3rd harmonic) means a multiplication of the fundamental signal by the given

Re: [time-nuts] PN/AM and 1.5Hz spur from frequency doubling?

Since the spur moved in frequency when the amplitude of the 25 MHz interference changed, my guess is that you have some grounding or cable leakage issues which are causing the measuring system to produce erroneous results due to overloading. Do you have all instruments and sources plugged into the

Re: [time-nuts] PN/AM and 1.5Hz spur from frequency doubling?

Hi I would bet that the spur moving is an indicator of either the 25 MHz transmitter carrier or modulator drifting in frequency. My guess is that the Maser does not drift :) Bob > On Jan 20, 2017, at 12:22 PM, Anders Wallin > wrote: > > I made some progress with

Might I suggest KiCAD? It is free and open source. It is developed by CERN (https://home.cern/) and a community of developers. There are no size limits and it does everything that Eagle does. Available for Windows and Linux. CERN uses it in-house and they do a lot of unusual projects

Re: [time-nuts] PN/AM and 1.5Hz spur from frequency doubling?

I made some progress with this issue today. It turns I was using a 75Ohm cable at some point (doh!) which caused a 'forest' of spurs far out. Possibly our other maser has a faulty/cut cable which behaves similarly. The final fix was to turn off our 25 MHz radio time-code transmitter which was

Re: [time-nuts] 10MHz to 25MHz

Hi If you think about it, current through the crystal is at least as important as “drive level”. They are related by the crystal resistance. As the overtone goes up, the resistance (in general) goes up. There are size constrained designs where other things get in the way of this. There are
