[time-nuts] Re: Manual for Precision Standard Time PST-1030 WWV Receiver?

[paul swed]

Walt congratulations on finding the documentation. At least some of it. I
tried to find some also without luck.
I find it very odd that the unit does not continuously send out timecode.
Otherwise it makes it very hard for some automation to use it. Like a stop
light or anything that has to wait for time to do something.
I have run into GPS modules that do not put a stream out until you send a
special command.
I wonder if the same is true with the 1030?
Its possible that its intended to support some automation system with a
internal clock that does reach out to correct its drift.
All in all nice looking units.
