I guess several comments here. I checked the xtendwave web site and its alive. But noticed no press releases or anything since last year. So sent an email just to see if it bounces back. Yes indeed since the great new formats sort of useless. Wonder if NIST could simply turn it off the PSK and go

Hi They tested the modulation format they now are using back in 2013. If they also tested the other formats that was done for a very brief period of time. I would think that knowing the transmission schedule of the various formats would be an important input into the chip’s design. More or

I have been able to consistently receive the WWVB phase-modulated data of what is now being referred to as Normal Mode since last summer, using an air-wound coil antenna, multiple op-amp front end, and a PIC microcontroller setup that I originally used for receiving the amplitude-modulated signal.

Hi We are in a “brave new world” of industry / government interaction. Watching how it plays out with WWVB (through real product) probably will provide a number of people with research topics for years to come. Yes it’s frustrating, a lot of it is as new to them as it is to us. I’m willing to
