Disappearance of Short Wave Time Signals at 5, 10, 15, 20kHz
 

analogdial: CHU


Yes, I get them at 3330. I will try their other
frequencies also. I use them as a last
resort as I don't know if they are just a
repeater for WWVB/H. Latency, y'know?


I thought about this a couple days ago, and
it gave me some pause: If the noise floor
for world band has gone up so much in the
last 10 years, then why is it only the time
signals that I no longer pull in like I used
to?

I can take the set outside, to a nearby open
park, and the reception of the time sigs is
just as awful as it would be if I put the radio
next to my computer or mobile phone.

puhleeez...

Have you tried tuning in CHU?

Maybe that's the problem. I don't think I've ever heard CHU on the 14MHz
frequency, and that's going back to 1971. The 7MHz one always seemed the
most useful, but they moved it a few years ago, so if someone had an old
book, they might think CHU wasn't coming in, when it's really just on a
different frequency. The 3MHz one seems fine, but mostly at night.

Oh yeah, 33.3mHz. I'm concerned about latency issues
and use them only as a backup. I don't know if they are
just a repeater for the American time sources.

Something else I was thinking about the last couple
days that gave me pause: If the noise floor has gone up
so much lately for world band, then how come it is only
these time signals that I can't pull in as readily as I used
to years ago?

For anyone who doesn't believe classic-era boom boxes didn't have
shortwave bands on them:

Zoom in and count how many bands are on the scales of
most of them...

Oooops, decimal point in the wrong place, should be 3.33 MHz

Huh? NO "latency" (not quite sure what you mean by that). Just the RF
propagation delay (at the speed of light) from their transmitter to your
location. No reason to use them as a "backup", they are every bit the
equal to WWV.

I don't know if they are
just a repeater for the American time sources.

Again, NO. They are their own man, so to speak. They use their own
atomic clock, radio transmitters, etc. A complete, stand-alone Canadian
equivalent of WWV and just as accurate as WWV. They are NOT WWV repeaters.

See:

for a complete description of Canada's time service.
