I first heard these a month or so ago here in southwestern Ontario. I sent an email to the local University engineering faculty to see if they were doing any experiments but they didn't respond. The signal was very strong so I assumed they were local. Thanks for the clarification. Would like to learn more. Because of the bandwidth they occupy and the strength, I find them to be disruptive. They do tend to land on frequencies that contain utility signals, so as an SWL I oppose them. They also seem to frequency hop. I've heard them around 10.8 MHz, 13.9 MHz and 14.5 MHz.

Wow! If only I had the ability to decode that stuff. I would finally be able to buy that top of the line ICOM transceiver I've been eyeing.

Twitter is a absolute cesspool, more people need to start boycotting it.

So, besides identifying what is causing the noise, of what use it it us? How do we decode/decrypt the signal? I bet there must be some smart computer hackers out there that can break it.

Good choice. Less static and noise.

X is great.

I like your content and channel here. While KZbin is no prize, I do not use or want any other social media so using Twitter, or Bluesky, etc is a hard NO for me. Good luck 😊

Thanks!❤

Is there a difference between the amplifier in the MLA 30+ and a standard LNA?

First, I will join both Facebook and Bluesky accounts to follow additional content. Second, BlueSky was launched by the former Twitter CEO that has almost all of what Twitter has. There is no for you that Twitter had that showed suggestions based on Twitter content history. X is getting more restricted in use for all accounts except for accounts with the blue verified subscription. More people are going to BlueSky. It will take time for BlueSky to be like Twitter before.

That must be some heavy encryption on that, the modulation / encoding sounds so uniform.

This should be banned! The public airwaves should not be used so large corporations can make money on the markets with high frequency trading.

Crazy. I haven't heard/seen them yet. Now I know where to look... I don't have a problem with them doing it, as long as they're respectful users of the RF spectrum, like we hams try to be.

Hello. I'm a newbee to the sw radio listening world and all the jargon. You lost me when you started talking about different HAM bands, 20m, 40m and so on and their relation or where they fit on the sw frequency range. Are there youtube videos I can watch to learn about this and how would I go about listening to usb lsb if I'm not familiar with any HAM frequencies yet. I just got a D-808 but am feeling a little intimidated.

Hearing / Seeing this at 1753 UTC seemingly centered on 14516 in Hingham MA

Namste.

Amazing

It's a pity that radio amateurs are limited in bandwidth of transmission. We are not allowed to use more than smallband like 6 kHz. Why not using more and transmit all information in half a second unlike ft8 for a minute.

👏👏👏

I'm going to have for 30 years and I couldn't care about crypto at all. But just the fact that these greedy Bitcoin millionaire billionaire people you know they got to use direct HF RF to make their transactions and generate noise all throughout the band yeah just wait till he put one of these near really really close to the band edges. I don't think these things should be on the air they're nothing but interference producers. They can put one of these transmitters on any cell tower and if that cell towers close to You broadcasting out at 20 kW signal on HF and you have an HF rig I'm sorry to say you're going to have some interference problems. I don't think these things should be allowed on the air all they do is generate noise and make money for a bunch of people who already have money. And here's something to think about with Elon Musk in there right now and all his satellites I worry about him saying the president dumbass and I'm sorry if that offends anyone but I don't care hey let's take all the ham bands and use them to make money I can see that happening. We must protect our spectrum whether it's MF lfh VHF UHF etc. because private interests look at them spectrum and have dollar signs in their eyes. And what's the current clown show in Washington DC I could see oh yeah I'm going to give the 70 cm handband to a satellite company I could see that happening

MARS is not ITU/WRTC recognised, it’s a local USA allocation without protection!

Only 2 weeks have gone by and there is another firmware upgrade from our friends at Choyong.

thank you Gilles, info video,73,de n8wjz

This code is something else... Looks to me like they're sending coordinates, times and names and something regarding a transport of equipment. A suspicious rendezvous of sorts, you should send this to the FBI or NSA.

I am vehemently opposed to any commercial use of public space. Is there a way to decode what they are transmitting? Or is it encrypted?

Any idea what modulation or standard in use? It looks a bit like some sort of QAM but the gap in the middle is odd

That is expensive for what it is.

Very awesome! Not very often that I get to hear much from India.

OTHR is very much a big interference producer as it just blasts out sounders looking for MUF and then fires up with vigor when it finds a suitable frequency. And in the southern latitudes, we have a huge problem with pirates in certain nations using any frequency they like for chatter. Many of the MWARA air frequencies in the 35m 8Mhz allocations have to contend with indiscriminate chatter +/- 1kHz away. Have not had any issue with HF traders so far, but now I know what to look for thanks Gilles!

Cool!

Thanks for this. It takes patience....and a lot of it. from Upstate NY USA

Can we decode them?. Just to see what is going on.

Good reception. Now if I only understood French.

Were you were picking up these transmissions around 2pm EST (19:00 UTC)? If so, it may be a coincidence, but the Dow Jones and the S&P both had a sudden drop right around that moment.

Forgot to mention. The MLA 30+ is indoors.

I was listing to this early today in English, on my S2200X on the MLA 30+ with A 10mm copper loop upgrade. I live in Northern Ireland. The signal was weak but clear enough to understand everything.

Any chance the signals can be decoded? Are they encrypted?

Probably encrypted, but if not, may be interesting trying to decode it.

many transmitter sites we hear are located near Chicago and other major eastern cities with large financial centers... Between these and the multitudes of OTH radars, many of the MARS/CFARS channels are heavily interfered with.

Ah, but the real question is, can we decode them? Haha, I bet they're highly encrypted. 😃

When it ends up messing up traffic in an aeronautical band or another utility, then something may happen to these transmissions. It’s about safety.

do we know where any of the transmitters are located?

When I was young we ran a wire out my bedroom window and attached it to the gutters it worked very good .
