Simon I have one solution cooking for wwvb and testing right now will release details maybe today. Its not perfect but seems to be doing a good job and is low in cost. Fix 1 rcvr and then you can use its output to drive all others. You may have seen some of my updates on Time-nuts. That said I am actually building a costas loop using ad 633s multipliers. One of my first LPFs in the 0 phase detector has low gain and I need to figure out whats wrong. It should be simple and I actually believe it may be a funky cap. It happens. When the 0 and 90 degree detectors are correct I will add in the combining AD633 and log time LPF. If the results of that effort is a reliable phase flip detection I caould get quite excited by that. A by product would be the digital modulation but thats for later experiments. Right now I would just like my old phase tracking rcvrs functional again. Regards Paul WB8TSL
