Fast code isn't mentioned in latest info I downloaded and
someone mentioned in a reply to one of my messages that it
was no longer transmitted.
Maplin MSF module hasn't been available for some years either,
but I swapped xtal and aerial of Conrad DCF77 module and that
works here receiving MSF better than it did DCF.
I'm still assembling parts for a DIY phase locked frequency
reference, but as I've found, that still requires GPS or
other method to calibrate to use for ntp.
