They claim to have shipped samples back in 2013, with production 
slated for Q3. I can't find anyone selling them.

Is anyone recording or decoding the new phase modulation? If so, what 
are you using?

I'm trying to measure WWVB signal quality with an old radio clock 
tied to a PC parallel port. Maybe I should ask for a sample of the 
ES100 or ES200 to compare.
