NOAA weather on WWV 10MHz

[IcomIcR20]

Last night I heard a NOAA weather broadcast being transmitted in the background of WWV on 10 MHz. Could it be a jammer?

Someone made a video of it: https://www.youtube.com/watch?v=gLY5frbU4bs and https://www.youtube.com/watch?v=daQGZXE7jFc

Sounded like a NOAA broadcast from MO.

Does anyone have anymore info on this?

Thanks!

WWV and WWVH broadcast weather bulletins and storm warnings.

Marine storm warnings are broadcast for the Atlantic and Pacific oceans and the Gulf of Mexico. The National Weather Service provides the storm warning information. Atlantic highseas warnings are broadcast by WWV at 8 and 9 minutes after the hour, and a Pacific highseas warning is broadcast at 10 minutes after the hour. WWVH broadcasts a Pacific highseas warning at 48, 49, 50 and 51 minutes after the hour. Additional segments (at 11 minutes after the hour on WWV and at 52 minutes after the hour on WWVH) are used if there are unusually widespread storm conditions. The brief voice messages warn mariners of storm threats present in their areas.

The storm warnings are based on the most recent forecasts. The forecasts are updated at 0500, 1100, 1700, and 2300 UTC for WWV; and at 0000, 0600, 1200, and 1800 UTC for WWVH. All marine forecasts rely heavily on the Voluntary Observing Ship (VOS) program for obtaining meteorological observations.

Continuing WWV 10 MHz Problems

This is not the standard WWV weather broadcast. It's actually audio for a MO NWS transmitter. This has been going on periodically for at least several weeks. It doesn't appear to be another interfering signal but rather audio on the WWV transmitter.

They are aware of the problems, but I heard it again this morning on 10 MHz. The NWS audio has quit now, but was definitely on there some 15 to 20 min ago. It does not seem to come up on the other transmitters, only 10 MHz. The audio sounds over-modulated and when it's there it covers the time announcements.

A friend of mine reported this to them and sent a recording a while ago. I believe he mentioned that the NOAA weather audio for all, or at least some, stations comes out of the same facility. Could that be true? If so, perhaps it's an audio routing problem.

Addendum...

One of the YouTube recordings mentioned that it was only USB, which I find it correct. That's probably why it sounds like it's on the carrier when listening in AM mode. I must have switched modes when I thought it had gone away. This would seem to be a separate transmitter. Trying to get a direction on it. - SW of MI, so could be MO.

Also, the youtube user that I posted a link to said that he heard a CB like roger beep as well.

Hmmm... NOAA WX audio coming through USB on 10 MHz and a "roger-dee beep." That almost seems like someone has a Motorola Micom radio with the end of transmission beep turned on, which is a more likely possibility than NOAA WX bleeding into WWV's transmissions.

Anybody get the call sign of the NOAA transmitter or the locality it's broadcasting the WX for?

It suounded like a MO NOAA station. It was hard to hear but I think I heard Jefferson City mentioned. I did not get the callsign.

It was definitely a NWS station that was id's as being from the St. Louis, MO area.

I first heard it on 10MHz WWV all the way back on Dec 6th, 2015.

It seems to be a purposeful USB signal that is transmitted on top off WWV's 10MHz signal from a different location.

Heard without problem in SE Michigan. Strange.

With FCC's HF DF capabilities, I'm sure they could track it down in a matter of minutes. But, alas, I believe 10MHz WWV is under NTIA jurisdiction, not FCC. So, until NTIA asks for FCC assistance, it will probably just keep happening.

The interference hasn't been interrupting critical data transmission on WWV yet, so they're probably thinking that whoever is doing it will eventually stop. That is until now, since it's really starting to get a lot of attention on the 'net.

Yep... and it was fairly strong here in NC... I could even hear it on a handheld. Whoever is doing this needs to stop...

The FCC's HFDF operations are shared, and unlicensed operation remains under their jurisdiction, anyway. All that needs to be done is for someone to complain about it.

Ha! I heard that this noon as well. Have heard some weird stuff on WWV but this was a first.

I have been hearing it up here in Iowa also. Pretty hard to miss, it is most definitely a NOAA transmission. Mike

There seems to be a lot of strange stuff going on in Missouri. Middle eastern "looking" men have been purchasing boatloads of cell phones, a lot of propane tanks were stolen and a hunter found explosives buried in the woods. Contact the FBI in Missouri and let them know about this - probably nothing, but you just never know.

St Louis area NWS radio id is KDO89

There is a lot of these nuts lurking on the air waves,some are out in the open with it and some are Passive at it ether way it;s the same interference,i think it's the Passive one that are the worst of all.......
