Disappearance of Short Wave Time Signals at 5, 10, 15, 20kHz
Disappearance of Short Wave Time Signals at 5, 10, 15, 20kHz
Thirty years ago, that ticking atomic clock could be picked
up on any shortwave receiver, whether one paid $40 or
$400 for it, or even on the boom-boxes of that day, of
which the majority featured at least SW1 & SW2. Starting
in the 1990s, it became increasingly more difficult to tune
them in, even with a dedicated shortwave radio. They'd
come in on only certain of those frequencies, or only at
certain times of day.
Now, they are all but inaudible except for once in a while,
every other day, on one frequency or another. All I hear at
those frequencies is loud static or noise.
What's going on?? I actually use the signals to adjust 'dumb'
clocks and watches(windup ones or basic battery ones).
