Hello to the group.
I have updated the WWVB costas loop. Thanks to some guidance from fellow
time-nuts. The key items; A error in the 74hc86 gate pins. A new 12 Mhz 10
ppm Oscillator that uses available known parts. These changes have been
tested and behave well. I would also add that the 150 uf filter caps needs
to be very low leakage. Also the TRF receiver is included no changes to it
just thought I would keep the set together. Regards Paul WB8TSL
