I would simply use any number of receivers and grab 60 KHz out of one or
could use the IF at 10 KHz or 1 KHz. But more fun to use 60 KHz. The cost
on the teensy components is very reasonable.

Hello Time Nuts,
Chris - maybe you can share that if that's something you can share right
now.
Jim and Paul,
Like Chris pointed out - on that audio board in the design he's worked on -
the Line In has L and R channels - the input resistance is higher than for
the mic input -
but I suppose it's
I received a good pointer about doing the BPSK implementation
but have just not gotten it done.

John had not seen this before. It is a AM decoder. But its an interesting
start if you are less than 1000 miles from wwvb.

Hi
The “ideal” antenna solenoid would be a bit longer ( say 2 X to 5X ).
The turns should be spaced apart by a few percent of the length.
( so turns over 30 or so … not so much …).
How much better is “ideal” compared to “just get it done?”. At least
from the stories that are told, it is
Paul,
Doesn't the post by Chris Howard above appear to be a good/great starting
point?
Seems like that approach could be extended.
