Yes, the wall clock and wrist watch people (I use both) would not be impacted according to NIST.

The whole format of the change has been under the guise of a government investment in a technology company. That's taken the whole debate about modulation formats out of the public eye. The goals of the new modulation scheme are a bit unclear, so it's difficult to evaluate alternatives. One would *assume* that the cost of silicon to demodulate the new format is a major part of the decision on the new approach. That said, yes there has to be another way to do this that does not nuke the old gear. > > - is there not a testing period, where results can be fed back as to the > compatibility or otherwise of the new scheme? There have been tests. There is no official / formal feedback mechanism for the tests. It's not totally clear what any of the testing results are. One would *guess* that they are testing a silicon implementation of their receiver in the field. One would also *guess* that nothing "important" is impacted by the modulation. > > - has there been any official response to your comments that the new scheme > stops existing equipment working properly? The response has been: Yes we know this breaks your stuff. They have put that in writing. There is a somewhat vague promise that a box that "translates" the new format to one the old gear can use could / would / might be developed. No idea at all what such a box would look like or cost. Also no idea how well it would perform. > > - can you involve your members of the legislature, or would the be either > inappropriate or a waste of time? Based on past experience - waste of time, even in an election year. The subject is to hard to understand and not enough voters are impacted. > > Cheers, > David > -- > SatSignal Software - Quality software written to your requirements > Web: http://www.satsignal.eu > Email: [email protected] > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
