Extra exam question E2E02

WhyWSJT-X digital mode transmit and receive timing is synchronized by keeping each station's computer clock aligned, typically to an internet time source. WSJT-X digital modes rely on precise transmit and receive timing, and that timing is kept aligned across stations by synchronizing each operator's computer clock, typically to an internet time source, rather than by anything transmitted in the signal itself, answer B. There's no sync-field or sync-pulse transmitted for this purpose, and it isn't accomplished by aligning frequency shifts.
