The K call implies that you have been licensed for a while.
Your ARRL handbook has information on what services WWV provides.
These include standard time, standard frequency and propagation information.
Reread your handbook for more information.

I've been licensed for about 2 years. I'm not an ARRL member, nor do
I have an ARRL handbook. I'm not trying to stir up muck here, I just
asked a simple question. What benefit do we get from WWV? I
certainly have had no cause to use it (at least knowingly) over the
course of the last couple of years.
Seriously, what am I missing out on?

The most direct benefit to amateurs is that it's a known and very
accurate frequency reference. Many HF transceivers have a frequency
calibration procedure in their service manuals that has you tune to
the WWV signal at 10 MHz. This is also important to kit builders to
make sure their frequency is accurate
Additionally, they broadcast solar conditions 18 minutes after the top
of every hour.
As far as ARRL membership, I would encourage everyone to join (in
addition to AMSAT, of course). A strong ARRL is vitally important for
the future of the hobby. There is no other group who can effectively
represent the interests of the amateur community in Washington.

Hello Roy,
That is a valid question to ask when someone it telling you to act on
something. I'm struggling to understand why it still justifies spending x
million per year. I set my clocks from GPS. I get propagation information
by listening for beacons, PSKReporter, Tamitha Skov, NASA... there is an
endless list (most produced for free) so I don't understand why it is still
relevant at this cost of several millions per year. It comes across as
someone arguing to keep horse stables open in New York City when most
horses have been replaced by Fords.
Can we see a list of technical reasons it is worthy of this expense and
reasons it is not worthy of this expense?
Sincerely,
Marcus Sutliff/N5ZY

Hello Marcus,
GPS doesn't work well/at all in-doors due to the ~1.5 GHz L1 frequency
that it uses.
WWVB, at 60 kHz, which isn't included in this shutdown proposal,
contains ASK (Amplitude Shift Keyed) time and date information used to
set "radio-atomic" clocks and can be received in nearly all of the
CONUS. It also serves as a stable frequency reference.
Be careful with "free" services. You'll likely get what you pay for. A
few million per year spread across everyone's tax bill to provide a
stable, calibrated time and frequency reference seems like a good idea
to me. Much better than some of the other uses of money that our
government has invented.

Content-Type: text/plain; charset=ISO-8859-1
The September/October issue of QEX that just landed in my mailbox has two
articles by WB0OEW and WA5FRF describing Doppler measurements of the WWV and
WWVB signals compared against GPS disciplined oscillators to measure
ionospheric disturbances, the second article describes the effect of last
year's solar eclipse on WWV signal propagation. There are other articles in
professional journals that I will look up if anyone is interested in reading
them. If WWV was not already broadcasting frequency and time signals,
ionospheric researchers would have to set up their own transmitter to do the
same thing, probably at higher cost.
https://zenodo.org/record/998278#.W4_heLgnaUk
https://www.nist.gov/blogs/taking-measure/weird-signals-listening-eclipse
The February issue of QST published an article by WD8DSB describing a TRF
receiver for frequency counter calibration with crystal filters to feed an
amplified WWV signal at either 5 or 10 MHz directly to your frequency counter.
Internet time servers and cell phone networks do not provide such a frequency
reference, and GPS disciplined oscillators are not an off the shelf item. It
is also good to have an independent check on the performance of GPS
disciplined equipment.
There are also millions of WWVB synchronized clocks that will be rendered
obsolete if WWVB is taken off the air. As with amateur radio, WWV and WWVB
will work even without a functioning internet connection.
The 6 million dollar proposed savings are well below the noise level of the
Federal budget process. The sentence about eliminating "measurement science
research that lies outside NIST's core mission space" is Trump-speak for
eliminating any climate change research from NIST's budget, WWV is about the
only item on the cut list that is not related to climate research.

Noticing that some ops' grid maps are still needing EN63, either all time or
confirmed in LOTW, I'll be up that way on Sunday September 9th. Look for me
on midday passes of AO91 and AO07, possibly others as well.

Dan (and all),
Most interesting. I don't subscribe to QEX but I have seen the article
to which you provided the link referring to WA5FRF's paper on zenodo. I
wonder if the article in QEX is basically the same basic paper formatted
for the magazine or is something completely different.
I can't find a link on the arrl.org web site to order just a single copy
of the magazine. I think I will email Steve directly for more information.
In any case, I have been doing something similar on and off for a number
of years using both WWV and 10 and 15MHz and CHU, I live about 35 miles
from the CHU transmitters.
My near real time 15MHz WWV dopplergram grabber can be viewed here:
http://users.aei.ca/~planophore/wwvGrabber/?? image is updated every 5
minutes and the web page automatically updates every 5 minutes
archive here:
https://www.dropbox.com/sh/0xwepl183kpgndm/AAD75zIT9bJjj36-d0eKitYua
The displayed bandwidth of the dopplergram is approximately +/- 3 Hz and
if you follow it over the course of a day or so you can get a feel for
what is happening with the ionosphere over the central US including Es
in the middle night
I use an ICOM R75 receiver locked to an ex cell site GPSDO reference
Here are a couple of more interesting scientific uses of the WWV signal
(for those who may have interest):

Hi Zach / Terry / Simone / Graham / Stefan.
Thanks very much for the advice / offers and links.
Hopefully there is a PA saving solution in there. Time to try the bird 43
out of its comfort zone, but also get the soldering iron out.
See you on P4A

David,
Try building the surface-mount version at the bottom of this page:

They don't need (or tolerate) much power, but they are cheap to build!
