I don't have the time to discuss this at length, but NTSC's

compensate for transmission problems (non-linear group delay) in
Europe.


Wasn't something done to either the NTSC transmission spec or the sets
that
largely alleviated that .. sometime after the original system started?..

Wasn't it the improved standards in receivers following the introduction
of
solid state technology? The transistorised sets didn't drift as much.

No, tube sets were stable. Remember, the demodulator is locked to the burst
signal.
