However, depending on where you are, you can typically only hear WWVB for a
small part of the day.


Does a bigger antenna help? Or is there just so much more background noise
than signal that it's a lost cause?

Hmm... isn't the data rate something like 1bps? Maybe they could do some
direct sequence spreading at 100Hz or so and improve the link margin a handful
of dB... :-)


If the problem is more or less random noise, what is the point of
spreading the transmit signal, since the same noise density would
appear in a specific bandwidth after despreading.

And lose the ability to be used as a frequency standard?


The GPS signal is DSSS and it can be used as a time and/or frequency
standard.

So, you want everyone still using WWVB for a frequency standard to
spend wads of cash to convert?
