I was once tasked with building some building sway monitoring systems. The
People With the Bucks were rather tight lipped about why they wanted to monitor
building sway, but I think this was closely related to the reason... and yes,
tall buildings wobble like a weeble (but don't fall down)

So sync limits are going down. 4G-TDD has a node to node limit of 3µs / node to
UTC of 1.5µs. 5g is lookin
I think there will be fewer useful parts.
The reason is integration. In the old days they would buy off the shelf
equipment like a GPS receiver that was inside its own box and was cabled to
something else. A better newer design would be to use a "GPS Chip" can
route the output not using a cable

Jerry that is indeed the likely reality. As more and more components become
integrated into super chips it becomes impossible to repair or replace
them. They are custom and proprietary to a company. Best of all the
supporting software will be a subscription and of course since the company

HI
Simple answer is: That depends.
A number of systems are going to network based sync. That moves the “good
stuff” back to a central location. The local “mini tower” will
have some pretty basic parts in it. The number of mini whatever’s goes way up
compared to an old style system. The number
Tom, Another question is will the surplus equipment have the same value to the
hobbyist? I have a lot of old gear like spectrum analyzers, scopes, signal
generators, etc that was outdated and sold for cheap. I keep wondering if the
same economics will apply to the equipment that is for instanc
