[time-nuts] Rebroadcasting time signals [WAS: La Crosse Clocks - ]

[Erik E. Fair]

I don't suppose there's any passive repeater solution for WWVB, e.g. antenna in attic feeding coax to another, hopefully smaller antenna to reach radio clocks with less-than-adequate built-in antennas in more unfortunately shielded parts of a house? Similar to how Community Antenna Tele-Vision (CATV) first started, lo the many decades ago?

When last I went web-searching (yeah, yeah, "googling") for this sort of thing, I ran across the smartphone WWVB "emulators" (transmitters - turns out that typical smartphones can be induced to transmit the WWVB 60 KHz signal as a harmonic of appropriate noises sent to their built-in speakers!) and wrote about that:
