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).

It helps if you tune in the right frequencies. WWV (and WWVH in Hawaii)
are on 5, 10, 15 and 20MHz, not KHz, and I think WWV is back on 25MHz too
after some decades of absence.

They never came in "all the time", which was a good thing. You could flip
to another frequency and get the time, but if you lived far enough from
the transmitter site in Boulder Colorado, it would give a mild indication
of propagation, if you didn't hear them conditions were bad, if you did,
then the given frequency range was probably open.

One thing that's happened is that the average house has way more
electronis now than in 1971, and mroe important, it's mostly digital and
usually the power supplies are switching supplies. That all adds up to a
lot of noise, which the signal has to overcome. Since many a shortwave
radio is now portable, complete with whip antenna, most people will start
without some outdoor antenna while decades ago most would start with one.
So you pick up the noise first.

Put the radio near the window, the time signals will come in as well as
ever. Because you're getting away from all the inside noise, and closer
to the signal source, especially if the home is shielded due to a metal
frame or a metal roof.

I am severely dyslexic and always confuse what's in
mHz or kHz. But I have distinct long-term memories
of these time signals being much easier to pick up
decades ago than now, merely by flipping up the
telescopic antenna on the radio or boombox I was
using then. Didn't have to be right near a window or
have an external antenna.

The wikipedia article also mentions, about halfway
down, a power reduction at one or more of the sites
transmitting time signals, around 10 years ago.

Perhaps people just don't rely on broadcast signals
for accurate time anymore? Getting the time from a
shortwave source guarantees next to no latency
issues, unlike getting those same signals off the
internet or the telephone. Yes - it matters. that.
much. ;)

I guess I have to respectfully ask what you are doing that requires such
critical timing...

For my ham station I am operating the JT9 and JT65 modes that are *VERY*
sensitive to timing issues; there are several free apps (Dimension 4,
for one) that will adjust your computer clock. Internet latency has not
been a problem, keeping my computer clock within milliseconds. Would
being within milliseconds be close enough for your application(s)?

Just the satisfaction of having the most accurate time on
my 'dumb' timekeepers(my aforementioned watch and
wind-up clocks, and even the one on the microwave).

Last time I worked in an office, most of my co-workers
wore watches, and many of them beeped at the top of the
hour. After syncing mine to the time signals on SW, I'd
go to work and start hearing watches beeping 2-6 minutes
before mine and up to 5 minutes after mine. Just amusing,
that's all, having the most accurate time and everyone else
is all over the place. As are the DJs and announcers on
local radio stations.

I've witnessed internet time being as much as 1/2second
behind the shortwave tones.

Well, I agree with you and have on occasion done similar to what you
have done.

That surprises me a bit.

1) Computer clocks are notoriously unstable; when you were comparing the
PC to the radio, how long was it since you calibrated the PC?

2) With the D4 app, you can option it to upgrade your PC clock at
whatever interval you want, once a week, once a day, once an hour, once
a minute or anything in between. The PC clocks, as bad as they are, will
usually hold for at least 15-30 minutes so if you set D4 to upgrade
every minute or two, you should be fine.

3) D4 will allow you to choose whatever atomic clock source you want to
use, i.e., you can choose a state University source closest to your home
to minimize propagation delay.

Having said all that, if propagation is good and you can hear them, WWV
is fine.

Fired my POS $14 portable, and it was blasting in at 5 and 10 MHZ, as
usual at night. In the daytime, I can hear it at 15 and 20 almost all
the time, and often at 10MHZ too. I'm not in a quiet RF zone, so I have
no idea what you're babbling about.

I've lived in CT all my life, and your situation
describes my time signal reception up until about
twenty years ago. Since then, the noise went up
and the time signals faded away. Not for nothing,
I do get them occasionally - 2-3x per week on my
Grundig Buzz Aldrin Edition 400.

Have you used different radios? Alot radios use simple RF stages which
can be damaged by static discharge. The input stage gets knocked out
but the radio still has enough gain to get some reception.

This sort of damage can go unnoitced because it doesn't affect the
internal ferrite antenna and the AM BC band still works fine.

As others have noted, the noise floor is now MUCH higher than it used to
be.

At least I know SOMETHING in the SW environment
changed - the noise floor, and for whatever reason,
probably budgetary, they reuduced transmission power
on some of those stations.

Don't know anything about a power change at WWV in the last couple of
decades. I have a 94 WRTH handy and it shows power at 10kW on 5,
10, and 15 MHz or 2.5kW on 2.5 and 20 MHz, same as now.

I've been listenening in the same area for over 40 years, even have the
same radios, and reception is sometimes uncertain but nothing I think
can't be explained by the usual propagation changes and the increased
amount of radio noise.

What's going on is, you're a trolling dumb ****.

This was all explained to you when you trolled a different group with
this same nonsense.

You showed that you don't even know what station you're trying to
listen to, let alone what frequency it's on. You've confirmed that
again, here. The simplest explanation is that you just don't know how
to find the station on your radio. Too stupid! This was explained to
you on the other newsgroup, but it probably could not penetrate your
granite skullbone.

You cited the Wikipedia article, too. But that's about a different
station, which broadcasts on 60 Hz. This was explained to you, too.
And the article does not say that the station reduced it's power about
a decade ago. You'd know that if you could apply a bit of reading
comprehension, but that's obviously not possible. And, of course, this
was spelled out in the other group. None of this ever gets through to
you, does it?

As for the ridiculous claim that most boomboxes and radios from thirty
years ago received SW, well, it's no surprise that you're an utter
dumb**** on that subject too. So now what? Find yet another newsgroup,
for you to pinch off more turds of trolldom?

This type of damage occurs on a fairly regular basis -- without anything
as drastic as an EMP. Just walking across a carpet on a dry winter's day
in a home with a low humidity level can create enough static electricity
to damage some radios...no matter how gentle you are. ;-)

Static common in the winter has been known to blow the input transistor
on a lot of radios. They put diodes across the inputs to protect them,
but they cause problems in some cases with reception, so many times,
they are clipped out of the radio. I've found out they were gone the
hard way, a couple of times.

Yes and no.

MOSFETs are very sensitive to static electricity, their very high input
impedance (especially with no circuit built around them) does nothing to
put a load on the static electricity, so they can be punched out.

JFETs should be less vulnerable, but in more recent times I've seen talk
of JFETs being vulnerable as if they are MOSFETs.

That said, I was using a Delco car radio as a bedside radio, and at some
point it lost sensitivity on the AM band, initially I just thought it was
bad radio conditions. But eventually I changed the JFET and it was back
to "normal" sensitivity", so it actually can be a problem. I have no
recollection of anything that might have done the deed, this was a few
feet of wire inside so it wouldn't have been lightning.

30mHz, and occasionally those time signals.


So why buy a new radio? Sounds like yours is working just fine.

Sony seems to top all the Amazon reviews for compact
units, by external and internal customers. What ever
happened to Sangean?


No clue what happened to Sangean. Also, price is no indication if you
will have a static problem. The Sony 2010 was a top drawer radio but it
had a MOSFET front end and was thus subject to static damage.

Unless you live in a Faraday cage, lightning can still be a problem. At
one time I had a 15 foot indoor antenna. I put an NE-2 neon bulb --
which fires at about 60 volts -- across it and ground and when a
thunderstorm got within 2 or 3 miles, the neon bulb would flash, so in
your case there was a slight possibility it could have been lightning,
but more likely shuffling across the rug or wearing polyester clothes

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??


What's going on is, you're a trolling dumb ****.

This was all explained to you when you trolled a different group with
this same nonsense.

You showed that you don't even know what station you're trying to
listen to, let alone what frequency it's on. You've confirmed that
again, here. The simplest explanation is that you just don't know how
to find the station on your radio. Too stupid! This was explained to
you on the other newsgroup, but it probably could not penetrate your
granite skullbone.

You cited the Wikipedia article, too. But that's about a different
station, which broadcasts on 60 Hz. This was explained to you, too.
And the article does not say that the station reduced it's power about
a decade ago. You'd know that if you could apply a bit of reading
comprehension, but that's obviously not possible. And, of course, this
was spelled out in the other group. None of this ever gets through to
you, does it?

As for the ridiculous claim that most boomboxes and radios from thirty
years ago received SW, well, it's no surprise that you're an utter
dumb**** on that subject too. So now what? Find yet another newsgroup,
for you to pinch off more turds of trolldom?


It is for clocks' synchronization. It is 60 KHz.

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.

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.
