WWV Freq and Time standard Question?

[Shortwavewave]

I cant find a chart online but theres one in a book i have called " NOW YOUR TALKING 5th edition"

It has a legend for certian things like ham freqs and Brodcast bands, well theres one that for WWV time freqs and i know theres one on 2.5, 5, 10, 15, 20 ,25mhz, well theres also one in between 300 and 420 mhz but its doesnt say that acual freq, any one know what it is or if it even still exsists?

I would of posted this in the HF forum but i want everyone to be able to see this and it also has to do with 300- 420mhz

Any help, thank you

My good man.....That would be " Generically Made Crap " ol' boy jolly good.

Oh....and would happen to have any Grey Poupon?

I never heard of one in the 300-400Mhz range.

Does anything you said have anything to do with what i asked?

Hope this helps you no UHF Frequencies.

Broadcast Frequencies
WWV operates in the high frequency (HF) portion of the radio spectrum. The station radiates 10,000 W on 5, 10, and 15 MHz; and 2500 W on 2.5 and 20 MHz. Each frequency is broadcast from a separate transmitter. Although each frequency carries the same information, multiple frequencies are used because the quality of HF reception depends on many factors such as location, time of year, time of day, the frequency being used, and atmospheric and ionospheric propagation conditions. The variety of frequencies makes it likely that at least one frequency will be usable at all times.

So do you think the chart made a mistake or could it be something hardly no one knows about?

I know nothing of the chart you are refering to, but these are the only frequencies wwv operates.

I've never heard of any in the 300-420 mHz (0.3-0.42Hz) range either.

I recall the broadcasts on 2.5MHz, 20MHz, and 25MHz were discontinued many years ago. WWV is should still be on 5MHz, 10MHz and 15MHz.

CHU in Canada is on 3330kHz and 7335kHz, IIRC.

I'm not into HF and it's been several years since I last listened to anything on HF, so even the info I have may be out of date by now.

Wrong. They still broadcast on 2.5 and 20 MHz.

Here is a link to the NIST web site http://tf.nist.gov/index.html

There was a GOES satellite time signal in the 468 MHz range, as well as on the old Transit satellite system that operated on 150 MHz and 400 MHz. There were receivers available for both systems to recover time signals sent by the spacecraft. While these provided very, very precise time signals, they weren't used as frequency standards.

I've seen 400 MHz listed as a standard TIME frequency, based on satellites. If you want to compile your own list, add the GPS birds, too. The time signals sent via GPS is accurate to better than 1 part in 10-12. GOES time is in the same order of accuracy. There was also once a proposed WWVS satellite time service that was proposed but never implimented. That was to be in the 400 MHz frequency range.

I think GOES time service is shut down now. Transit is long gone.

There is the 1.25 meters band: 222 MHz through 225 MHz. Maybe that is what you were thinking.

Another might be the 75/80 meters band: 3.525 MHz through 4.0 MHz (or 3525 kHz - 4000 kHz).

Here it is its i found it look in between 300mhz and 3ghz and you will see the grey area that tell you what it is its on 400.1mhz as well as the other WWV time freqs

I juast dont know if it is on AM, or FM, or maybe even WFM

Frequency Bandplan Charts

You can download an amateur radio frequency bandchart from the ARRL here: http://www.arrl.org/FandES/field/regulations/bands.html

Here is a very good chart (Adobe Acrobat pdf) that has pretty much the enitre radio frequency spectrum from the US Department of Commerce - National Telecommunications and Information Administration: http://upload.wikimedia.org/wikipedia/en/9/9d/Allochrt.pdf


Here are some other web site links:

I found it...??

Here it is its i found it look in between 300mhz and 3ghz and you will see the grey area that tell you what it is its on 400.1mhz as well as the other WWV time freqs

Here is a definition of what it is:

Standard Frequency and Time Signal-Satellite Service: A radiocommunications service using space stations on Earth satellites for the same purpose as those of the standard frequency and time signal. This service may also include feeder links necessary for its operation.
​

I juast dont know if it is on AM, or FM, or maybe even WFM

Of this I am not sure.

More info:

The signals are apparently still there, but NIST is no longer involved. The satellites are operated by NOAA. NOAA is broadcasting time data, but it's no longer of the same accuracy as when NIST had it.

 

[zz0468]

I juast dont know if it is on AM, or FM, or maybe even WFM

It's 100 bps phase shift modulation.

So i wont be able to pick that up?
