OT: WWV-driven station clock that displays zulu time

For father's day, I'd like to get dad a station clock. Do you have any
suggestions?

I want it to sync with WWV.
It must display Zulu time.

There are scores of WWV clocks on the web, but no way to tell which, if
any, can be set to GMT. Your suggestions will be gratefully received.

I'll take replies off list. Thanks!

73, Wayne Conrad

WWV-driven station clock

I use a "Sky Scan" Model #88902 "Atomic Clock" purchased at Sam's Club.

Easily configured to display UTC in 24 hour format. Leading zero suppressed. Also includes an inside - outside thermometer.

Large @2 3/8" numerals. Has indicator to show it has been synchronized.

Overall @9" high by @11" wide. If you are handy with a saw, you can remove the "decorative frame" and reduce the size to @ 6 5/8" high by @8 5/8" wide.

Was something around $20 if I recall correctly.

72,

Tim

Re: OT: WWV-driven station clock that displays zulu time

I recently discovered that Win7 allows you to show two different times in
the little rhs status area one of which I have set to UTC.

I am fortunate to have a Heathkit "Most accurate clock", which scans for
WWV or WWVH on up to 3 frequencies (5, 10, 15 MHz), locks onto the
strongest signal, and decodes the time code. It even has provisions
for propagation delay offset (in milliseconds) depending on how far the
user is from the transmitting station.

You just cannot believe how many guys try to convince me to sell it to
them, but, it ain't going anyplace. It is at least 25 years old,
probably closer to 30, but still runs great. All that is required is
the occasional touch-up of the PLL tuning, typically once every three or
four years. . Modern design could probably remove that minor issue.

That would be a good project for the likes of Elecraft. A truly useful
station accessory, and a good candidate for a kit to keep the "gotta
solder something" types happy. An updated design should be easy.

Yep. It also has sidebar gadgets. I have two neat-looking clocks, one white
and one red, for local and UTC respectively.

My $19 "SkyScan Atomic Clock" is about as accurate as my ears can tell
when compared to WWV. It, too, is listening to WWV and decoding the
transmission. I think the "Accurate Clock" market is pretty saturated
these days.

The Lacrosse Technology WS-8115U, WS-8157U and WS-8117U are all WWVB
based clocks that can be set to display UTC in 24 Hour format. They
can also display indoor/outdoor temperatures and day/date.

The Lacrosse Technology products are available several places on-line
look for places like www.atomicclocks.com, www.atomic-clocks.com and
probably other places ... check around for the best price and make
sure you can download a manual in advance. There are many brands of
"Atomic Clocks" available on-line and they all seem to be based on
a limited number of commodity receiver/clock chip sets but most do
not have on-line manuals to confirm the ability to select time zones
other than ET/CT/MT/PT with/without DST.

Re: WWV-driven station clock

Hi

I seem to recall that there was a discussion some time back about adding this feature to the K3's firmware. The K3 would sync to a WWV broadcast on shortwave and correct the clock just like the famous Heathkit WWV clock.

I have 2 of the original Heathkit clocks, one I use and one is new in the box. I have been offered goldmines for these clocks. I personally dont understand why they are still so sort after when any GPS receiver can do the same job.

There are many Nixie clocks sold on Ebpay with GPS sync. The blue VFD Nixie clocks look very nice.

Re: OT: WWV-driven station clock that displays zulu time

In reply to this post by Joe Subich, W4TV-4

The problem with the La Crosse clocks and all "atomic" clocks is that if
you have a computer near your operating position (as most of us have
these days), the clock must be at least 6 feet away (as per the
instructions that come with the clock) otherwise there will be no
reception of the WWVB signals. That means you will need to get a wall
mounted clock that is large enough for you to see and it probably should
be mounted on a wall that is facing the WWVB signal you are trying to
receive for best reception of the WWVB signals which is hit or miss most
nights. (e.g. West if you are East of Ft Collins, Colorado). The model
WS-8157U-IT can be set to UTC if you wish.

Re: OT: WWV-driven station clock that displays zulu time

Mike,

Display the clock, click "display time and date settings," select
the "Additional Clocks" tab," Check the "Show this clock" for the
first additional clock, Select "(GMT) Coordinated Universal Time"
in the select time zone box and put "UTC" n the "Enter display name:"
box.

Both Vista and Windows 7 allow for up to two additional clocks. The
second clock is visible when hovering the mouse over the clock in the
notification area of the task bar.

Re: OT: WWV-driven station clock that displays zulu time

In reply to this post by k7hbg @dslextreme.com

As with all things RF, "your mileage may vary".

I have a wall-type clock I picked up at Dayton a year or so ago, in the
bargain pile in the flea market for $10 (brand name unknown, but it has
a sticker on the back that says "Made in China"). Works fine, until you
get a marginal signal from WWVB (which is on 60 kHz, by the way -- check
out the WWVB web site [http://www.nist.gov/pml/div688/grp40/wwvb.cfm] to
see how they pump out a lot of power out on 60 kHz, also the format of
the timing signals, which are set at the rate of 1 bit per second).
Apparently some of the chip sets don't bother to check the error bits,
and will set weird times and dates if a bit gets lost here or there. I
keep this particular clock in my office on top of the cube cabinet so it
at least has a clear view west over the cube farms out the other side of
the building, and sometimes in the morning when I come in, it will be
showing a completely wrong date or some odd time. Placing it in the
nearby east-facing window across the aisle and forcing a synchronization
corrects it.

I also have a Citizen 'atomic' watch that works quite well at home at
night on the dresser (the WWVB 'atomic' clocks auto-sync at 2 or 3 in
the morning local time to take advantage of the enhanced night-time
propagation on 60 kHz), as long as I keep it away a foot or so from my
CDMA-based Sprint cell phone. Otherwise, emissions from the phone
charging circuitry seem to interfere with it.

I would certainly welcome something that would increase the accuracy of
the clock in the K3. It tends to wander quite a bit, and it's a hassle
to have to dump all the various programs I have talking to the K3 over
the serial port via Larry's (N8LP) excellent bridge program, so I can
run the K3 utility to synchronize the K3 clock to the computer clock.
You'd think that after spending thousands of dollars on a rig like the
K3, that it would at least keep good time. 8-p

BTW, that last statement is what MY customers tell me about MY product
8-) (and no, it's main purpose in life is NOT to keep good time,
either). I just couldn't resist using that argument on someone else.

I agree with Jim's and Julian's comments and would dearly love such
a frequency standard for in-house recalibration of the used
ex-professional testgear I occasionally pick up.

As someone said, the atomic clock market is saturated and who could
disagree, however, I don't see any clocks, tied to frequency standard
transmissions, that offer a sub-standard output.

Hmm! The ability to select the monitored source (and maybe auto-QSY
if signal is lost, plus the ability to display GMT as well as local time,
together with selectable 10, 5 and 1MHz outputs.

Surely, something of this nature would appeal to a wider audience than
Elecraft users alone?

For many years I've been using the "classic" shipboard style
with the CW and 'Phone silent periods marked. Lately I had a
clock shop put a WWVB "atomic" movement in one. Cheap it was
not (mostly labor) but now I get the best of both worlds.

For ham radio purposes, using HF WWV/WWVH may be acceptable to
some, but precision frequency standards no longer use it. At
10 MHz, a one-second measurement can only yield an accuracy of
1 part per million (10 e-6) - one Hz per MHz - which may be
great for ham radio but is insufficient for today's communication
timing requirements. The concept of the HF "Standard Frequency"
station was great for pre-1960s technology.

That's why WWVB (and WWVL in its time) were put on the air.
The ultimate, of course, is a cesium or rubidium standard (1980
technology) having 10 e-9 or better accuracy.

All it takes is money.
