Funny you mention that. I actually have a remote chance of actually doing
I know a guy who knows a guy... I really don't want to get tangled in that
total distraction actually. The value of the chip in at least a predictive
wwvb d-psk-r is that you could easily obtain the nasty DST data. As I have
only recently realized due to some pushing from Tom thats the mess not the
31 bit timecode. Quite the surprise actually.
The everset chips actually don't give you useful things that you need like
raw wwvb carrier or much else. So you are only leveraging the message for
the dst clues.
Lot of pain for little gain.
