Also....
I just checked my modded 1132CU accuracy. I have not set it in 4 moths.
It has gained a solid second. I checked carefully making sure my computer was very updated to the National bureau of Standards using Tardis.
I gained a second in 4 months.
This is a fairly stunning accuracy.
So it will be within 1 minute accuracy to about 20 years.
If this is the chip Smarthome put in the unit, I think this deserves "wow".
They also added shielding as I mentioned in this post...
The problem for me is,,,,,, I have become kinda attached to my modded module. I'm not sure I want to give it up !!... hahaha....
I do have the military spec version of the chip coming soon. It had a 4 month lead time from Mouser. Even better specs then the chip I have been describing. Not that any normal human would even need better then 1 minute in 20 year accuracy mind you... Still I want it anyway...
On a whole different project... I do have a different time base measuring device I have just restored...
1950 frequency counter
