Radio Receiver
AssemblyA ferrite-antenna receiver tuned to the 60 kHz (WWVB) / 77.5 kHz (DCF77) longwave carrier; it amplifies and demodulates the once-per-second amplitude-keyed time code and hands the decoded bits to the microcontroller. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
