I would be very surprised if "aviation-grade" receivers are better than your new average handheld Garmin. > I would expect planes and other potential "high value targets" to have > receivers of similar performance. I would expect the opposite, since important receivers - say for timing of power generation, timing of bankingsystems, etc typically runs forever often beeing 5 to ten years old before uppgrading. -- Björn _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
