Hello to the group. A very brief update. WWVB was not psk modulated all weekend. But starting on Thursday I was able to run the d-psk-r using a spectracom 8163 and it does indeed work here on the east coast. I want to get a bit more time under the belt. If the PSK had run all weekend I would have more confidence. I have a document written that I will share on how I am doing it. There are numbers of other approaches. But it looks like this one does work for at least 1.5 days. The other approach being worked on is a pure costas loop. Thats been slow. Not because its hard just time to do it. Lastly there has to be some very different approaches to this such as a purely digital correction. Sort of a digital delay lock loop were you trigger on the edge sync a non synchronous higher frequency clock and count cycles looking for an incoming phase shift..... Just not enough time in the day.
