[time-nuts] SSR-6Tr vs Lotus M12M

Newer is always better :)….

The real question is : 

Did the guys who designed the the hardware and firmware in a 10, 20 or 30 year old box optimize it so that a better GPS would improve the performance of the box? 

Put another way:

1) Will the software filters tune in a fashion that allows better performance in less time?
2) Are the hardware TDC’s high enough resolution to keep up with the new GPS? 

That assumes that the M12M Lotus 100% matches the part in your older boxes as far as commands and i/o strings.

Someone designing a box for selective availability conditions would have a much different task that a modern designer. It’s reasonable to guess that they could come up with a very different solution to the problem.

Both my XLI and FEI Zyfer time and freq rec's use versions of the M12. Does anyone want to weigh in on which offers superior performance?
