[time-nuts] Re: Drop-in replacement receiver boards for Z3801A

[paul swed]

I ordered a spare Synergy board numbers of years ago. That board did have a
tiny micro on it that did the conversion. I may guess exactly the same
here.
The benefit is when the stock GPS module goes bad, its a great way to
recover the 38XX class gpsdo's. Added benefit seems to be more receive
channels, faster cold/warm start, most likely better sensitivity and
perhaps filtering.
It does appear to be a drop in. No setting up anything.
