Christmas shopping?
Here are good prices on the LaCrosse UltrAtomic for a Time-Nut.
Lowe’s is selling the La Crosse UltrAtomic 404-1235UA-SS clock for $40.00

Hi
Most OCXO’s similar to the 8600 series use a glass bead thermistor up around
100K ohms. The range of betas available is pretty limited up there. They likely
used two in an attempt to reduce the impact of forced cooling to one side vs
another.

Does any one have information on the two thermistors in the 8600 and 8607.
Thanks Bert Kehren

Mike,
The BPSK format enhancement applies only to 60 kHz WWVB, not the
short-wave WWV in CO or WWVH in HI.

Hi Tom -
I wonder if WWVH is also sending in the new format for you guys on the west
coast, although you guys are closer to WWVB than I am, and the La Crosse
just works great. Regards - Mike

There were couple WWVB threads recently.
One of the questions was if the La Crosse UltrAtomic 404-1235UA-SS wall
clock is still the only WWVB clock that uses the new BPSK format. I
learned that 3 different companies made prototypes but only La Crosse
went to market. So at this point the
Thanks to all for your comments. To minimize crosstalk, the plan is to
clock the entire FPGA from the 100 MHz OCXO. The other inputs will be
sampled at the input pins by D flip flops clocked by the main clock. There
will be some unavoidable interaction between the CLK and D inputs to the
flip
