Re: [time-nuts] Fake new LPRO 101 Rb's on Ebay?

I am suspending purchases directly from China for now.  The whole country is in chaos, according to our media.  Their resources are strained.  Too many chances for something going wrong - ignored, lost, delayed, damaged, etc, etc, etc.  --- (Mr.) Taka

[time-nuts] Fake new LPRO 101 Rb's on Ebay?

Yo Bubba Dudes!, There are two vendors on Ebay selling *new* LPRO 101 Rb's for around $160 each, with discounts for larger purchases.  The general price of a used LPRO seems to be in the $250 to $350 range.  Anybody have any ideas?  (Discount for coronavirus?) In all seriousness, can the

Learned Gentlemen, Thanks for the two references for affordable 10 turn precision pots. This will allow me to go back to my original and simpler circuit of a series string of resistors and in that string connecting the 10K10 turn pot in parallel with one of the resistors, probably a 1K, which

Hi Regardless of it being a double or single oven, it’s a good bet that it did once and still does meet the original temperature specification with some margin. The open question is - what was that spec? Bob > On Feb 3, 2020, at 3:58 PM, gandalfg8--- via time-nuts > wrote: > > Ah, > I now

Ah, I now have a full copy of the design paper, "A new kind of view for a Double oven Crystal Oscillator", thanks John. The authors do reference the 8663 but as far as I can see only in a photographic example of what was previously available, before then launching into the discussion of their

Cellphones in use in urban canyons or places with foliage will have substantial GPS signal losses. Mapping programs hide this by using algorithms that guess you are continuing to move along the same street at the same speed. e.g. just slightly smarter than dead reckoning. It will always try to

Bit late, sorry, but I've just heard that yesterday's date was the first palindromic date for 909 years, and there won't be another for 101 years. Even more significantly, it's palindromic in all three common 'long' date formats: UK (dd-mm-), US (mm-dd-year) and ISO (-mm-dd); I believe
