WebMay 6, 2024 · I've made some really hacked code ( I need to optimize it) to get my module to receive WWVB data using pulseIn. It then fills in an integer array with either a 0, 1, 2 (marker) or 3 (unknown/bad data) based on the length of the LOW pulse. WebJun 26, 2024 · The original WWVB signal resides at 60khz, being lower than your local AM band won't carry very far. For this reason, carrier frequencies of 5, 10, 15 and 20 MHz are used to extend the useful range over much longer distances. You can tune these at night on a shortwave radio and hear the time encoded signal with some voice cues.
