[time-nuts] DSP-93 Source For WWV/H

[John C. Westmoreland, P.E.]

Hello Trevor,

Yes - I see that now - thanks!

Wow, 'c2x assembly - this will be fun.

I noticed in his paper(s) (I used the wayback machine) - he has:

"The clock should be rewritten in portable C for use on a fast workstation
with integrated audio codec."

I wonder if anyone has taken this source and done that already.

73's,
John
