🚀✈️ Ever wonder what it's like to measure #WWVB #Doppler #shifts mid-flight? It's about as thrilling as watching paint dry, but with more tech jargon and fewer frequent flyer miles. 😂📡 #WWVB #NerdGoals

My favorite part of my #WWVB project was seeing the doppler shift of WWVB during my flight.

Don’t tell the fascists they’re exporting time to Canada for free. #WWVB

Developing HackRF Pro (in production now!) has been a lot of work, but I've been able to have some fun along the way.

For North America folks interested in low-maintenance, accurate atomic/radio clocks, but live outside the expected WWVB range¹ :

The La Crosse UltrAtomic large wall clock has a semi-novel internal two-antenna design that allows the WWVB signal to be picked up at greater distances (such as southcentral Alaska) when conditions are favorable (especially at night).

And since the modern WWVB signal² embeds DST/ leap seconds / etc well in advance of actual changes, and since the oscillator is relatively low drift ... the time accuracy window is pretty robust.

It takes either two or four D batteries. Four will get you around four years of life in ANC (in my experience).

So between the self-setting and the long battery life .... you can put a visible, affordable, low-maintenance clock in a hard-to-reach place, even in Alaska.

And here's a great teardown for the geeks:

ooh, this was better:

[15:19:27.130070 0.020378] received UTC time = 2024-08-18 19:19:27

but it still took nearly two hours to get a fix

#wwvb

it took the ES100 on the Arduino from 08:15 in the morning to 12:27 this afternoon to tell me that the NIST time according to WWVB was 2030-08-24 22:40:21 ... umm, that seems a little off.

Today is the first day I've found a use for an Arduino Due board that I bought 11 years ago.

(It's so old that - for Toronto nerds - it was bought in Creatron's east-of-Spadina location)

I'm getting slightly more out of my ES100 WWVB receiver board with it, but it's still no magic time-sync machine

(yes, I know that WWVB doesn't work that way. And I know that one of the broadcast antennae at Fort Collins is off the air)
