Hello time-nuts, I realize it is fairly short notice, but WWV is celebrating their first transmissions in 1923 this week. I received the attached flyer regarding the Thursday evening lecture and Friday tours of NIST. My understanding is that WWV itself will be having an open house on Thursday as well. If you desire to attend you can call the station at 303-497-3914. On a different note, but kinda related, Michael Lombardi of NIST (K0WWX) has an article in the current issue of QST magazine - Measuring the Frequency Accuracy and Stability of WWV and WWVH.
