This is a QSL for WWVB 60kHz for a 2008 reception. If you own an “atomic clock” or a “radio-controlled clock” and live in North America, you picked up this station when your clock reset to the current time. Yes, this is the station which is received by these clocks when they reset their time It is done by a simple code. I would assume that they would not send a QSL verification for a clock resetting. I received the station on my SDR-IQ (Software Defined Radio) on its waterfall display mode. The display came out nice and clearly showed that I was picking them up.
