My old Heathkit clock received WWV on 5Mhz, 10Mhz and 15Mhz. You could turn up the audio and listen if you wanted. > Incidentially, it is _WWVB_ on 60 kHz, not WWV or WWVH on HF that is used by > these "radio controlled clocks" for periodic time checks, usually once a day > during the early morning hours (local time). >
