[time-nuts] WWVB and Chronverter update

[paul swed]

Thank you for the responses.
I have not reached out to him yet. Want to see if there are other issues
and I can easily add an external 60 KHz source and modulator right now to
verify the other functionality.
There is no schematic nor source code its a 8 pin uproc chip and as such
has almost no IO. I can easily see a very simple fix but needs a change to
the code behavior. (The chip it self can not do the modulation function.
Thats why its OOK).
But if the carrier were left on there is a LED that blinks to the time code
sequence and that can drive a 1 transistor or diode modulator.
Regards
Paul
