The main thing I learned at NIST last week (video coming soon!): you can NEVER have too many oscilloscopes :D

(And frequency counters)

Life goal achieved: visiting NIST-F4, the US's current primary frequency standard. I learned SO MUCH I didn't know about how UTC(NIST) is generated and distributed. I can't wait to share it in a video!

(Thanks to everyone at NIST who answered my time-noob questions!)

You get one guess as to where I was today.

Hint: I had a great time!

Tuning in WWV from St. Louis with my dad @radijoe for an upcoming @GeerlingEng video.

10/15 MHz fairly clear during daytime with MLA-30+ antenna and a HackRF Pro @OSSDRLab sent us for testing!
