Yeah - ive seen that one already and first thought hey, you have already shown the place is revealed, and probably Sam is just a cartoon recognizable payload. The clients that want simultanous support of: {AM, FM, FSK, QAM, QSFP+, 400gbethernet } and pay for AM are the worst clients you can ever encounter :)
Mel Blanc, the voice of Yosemite Sam, was an avid CBer and used to talk in some of his Warner Brothers cartoon voices on the air in Los Angeles in the 1970s. He would be proud to know his voice still gets used for oddball radio transmissions.
Ironically, he was also not especially fond of carrots, especially raw.They couldn't get that sound right any other way, leading to buckets upon buckets of ABC carrots on the sound stage. No, he wasn't allergic - at least aside from that "allergy" many of us have to anything remotely healthy - that is just an urban legend like much of the lore surrounding the broadcast in question here.
@Cemi_Mhikku another sidenote,Carrots were touted as being good for your eyesight at the same time the British invented RADAR.The whole carrots being good for eyesight was a farse to explain early detection of aircraft.
I work in Wi-Fi, and we still use NI PXI cards ("pixie") for signal generation and analysis. If the customer didn't know about PXI and its capabilities relative to HP/Agilent rack equipment, it was undoubtedly a military customer.
one major downside to wikipedia is that primary sources in the form of witness accounts are not accepted. you have to be interviewed or covered first (like this video), and THEN you can be used as a source for wikipedia. its annoying, but it does keep malicious people from claiming wild things they witnessed. also i love that it was a tech working with labview and not realizing he was transmitting for real hahaha. that is the most real engineering thing i've heard in a while. thankfully there is no fine for broadcasting in that band!!
No that's not good enough, it seems. Take a look at Wikipedia: this has all been reverted instantly. Apparently receiving this information and relaying it to the world here "Just stinks" according to the gods of Wikipedia!
Sadly Wikipedia's gatekeepers often seem to just want to play god. I've heard of numerous cases where genuine information is rejected. Wikipedia is amazing but hugely flawed.
Which makes wikipedia inherently flawed and not to be trusted. The truest, most primary source will always be the person responsible for the action. Wikipedia places a third parties' opinion of your actions over yourself as posits that as the truth. Don't trust it.
Wikipedia is a joke. The fact that people invest so much of their time working for them for free is one of the most incomprehensible things to me. The most valuable thing someone has is their time, so it really blows my mind people would spend it laboring for free for wikipedia. Especially since its well known that its not always accurate and that it has a heavy political leaning that prevents it from being objective
@@agranero6 While there is many issues and problems with wikipedia it currently is the best we have. While I think we must continue to make it or something better we should not discredit the good parts. Many will use such examples as a reason to dismiss everything on the site. But that does not mean we shouldnt bring to light the problems nor hide them away to never be worked out. I guess what I am getting at is that we shouldnt just stop trying. If the wiki mod editors failed you repeatedly, we should continue to challenge them. Even if it doesnt work out in the end we must not stop trying to make it better and fair other wise we are failing the ones who come after us.
Brilliant as ever, enjoyed all aspects of this video from the technical detail, as thorough as ever, to communications/emails to the person involved. Could easily watch your videos all day, its easily some of the best radio related content available on the internet.
Watching this and thinking back, when I was young, a friend of mine had a walkie-talkie that would pick up on something quite unusual, it was a male voice that would just seemingly spout nonsensical things like "Joy to the Island of Centifica" and just listing out different home electrical appliances and other random stuff. Thinking logically now, I believe that it would most likely have been a test of some kind, either a test for signals intercept operators or like Yosemite Sam here, just some automated thing randomly sending nonsense for a specific testing purpose. I remember it scared the shit outta me, cause it made no sense and the voice was so clinical and creepy. This was in Sydney Australia around 2002-2003? Not sure what frequency my mate's walkie-talkie operated on, but likely to be 27 MHz ISM.
Interesting. I was doing some RF work in Yuma at the same time. We had some new compartmental but not secret monitoring systems, which had weird audio tracks. We were exploring a variety of new encryption and clear (without encryption) transmissions in prep for the follow up for the desert warfare back then. There were unknown factors we had to overcome. What how & who are all likely still classified but it's fun to see what public interceptions found back then. There was a lot of noise in the spectrum from 2001 - 2005, I'd never heard of this Yosemite Same station until now. Good on you for figuring this out.
THIS IS AMAZING! My friend and I have listened to this and tried to drive down to New Mexico to get a better signal. You are such a hero for figuring this out!
So let me get this straight. Somebody "Didn't think anyone would notice" transmissions of a Looney Tune every 10MHz between 10-70MHz at a minimum of 100W up to half a kW?
That was very fascinating and interesting. However, it begs the question, who was "the customer" and why did they need such a set up? Unless I missed the answer in this video, then I say we need a part 3 to officially put this to rest.
The customer is a polite way of saying 'a three letter agency' without saying a three letter agency. In the same manner, specific components of special weapons systems are called "items". Security clearances were specifically mentioned which doesn't happen in private industry outside government work. The customer was obviously the U.S. Government or a contractor for the same. The need is simple. It's for operational testing of radios, almost certainly mobile receivers.
@@Peter_S_ Have you heard about the stock traders "take over" of HF? It's big news in the ham community in the USA. Less latency than over the internet.
This is fantastic. He had no idea what his work would start. The technical details reminded me of encabulators. I wonder if side fumbling was an issue?

This sounds like they are looking for the best frequency from the location to transmit on. Like a ham operator looks for the beacons from each band to know what frequency is useable. The idea being to use the highest Mhz frequency available. The time of day and solar activity and weather will be different and the ability to use the same frequency at the same time each day will change. I wonder who would be able to use whatever frequency they wanted and whatever modulation and signal type they wanted ? I am thinking this is for military use.

So they were building the ultimate ANNOY-O-MATIC transmitter that ensured any desired waveform could be emitted at a precise time from anywhere by users so authorised. Sounds like a jamming system. Either intentional or not. Or the ability to insert messages into other stations transmissions. Love the technical information and illustrations of the equipment!
I don't think that's the case based on the data burst transmission at the beginning. It's more like the "Let's just ping everyone all at once" kind of solution, and if you could decrypt it, the transmission was for you.
Back in the 70's in the south of essex i used to love to listen to various odd things on the MW band, one repeated 5 second tune used to go on for hours & sounded like a few notes from a trumpet. I'd love to find out more about it now 👍 and possibly use it as a ring tone.
@@Maschine103 it was around the late 70's early 80's. It used to pop up over most ( if i remember correctly) of the mw frequency, i would have been around 15 at the time & it puzzled me as to why it was transmitted!!

It was probably something government related so it wouldn’t have been an issue. Have a look at the first video, the FCC did provide a bearing to amateurs

The "why and what for" is a different issue as is getting the offending signals to cease. It always amazed me how defensive people are when you tell them they are x-mitting an Interference signal on a licensed freq and violating the FCC laws.
"a very controlled and flexible environment"? Sounds like the Government had something to do with this. Thanks for the video! Your content is always top notch! KG5WXU 73
I worked for many years with that same equipment. The performance claims are real and I saw it work out this way many times. We even flew simulated aircraft navigation equipment on a single engine plane. The only thing he left out is the ability to transmit multiple signals at the same time, record and playback in RF things like the entire FM Broadcast band.
And bear in mind this was all done nearly 20 years ago. I can only imagine the hardware (and software) that's available for doing similar, and even way more feature-enhanced functionality today, probably in a package 1/10th the size. Probably the bulk of it could be done on a tiny microcontroller-based module with simple outputs to antennas.
That tone sounds like a DMR or P25 digital Motorola signal I wonder if you could get the ID in that Usually they transmit the network and the talkgroup and channel
Wow, great work, Lewis! It certainly took some time to happen, but I'm glad the longstanding mystery has been put to bed. But I suppose this begs the question: What kinds of end-purposes do you think such a system would be used for? Cheers!

5:16 first time i seen one of these in use - just built one for leo satelite use - i think the idea is omnidirectional circular polarisation... Kevin..
That was a good video and really informative. But I don't know, man. One day, about eight or nine years ago, I saw a random RUclips video on abandoned missle silos around the U.S.A. that people were exploring and more than a few of them had painted pictures of Yosemite Sam on some of the walls and I have never been able to shake the annoying hunch that there might have been some connection between the silos and the Yosemite Sam numbers station mystery.
“System security and user monitoring are provided in two layers. Standard security measures such as a firewall to the Internet and ***Windows XP*** accounts provide the first layer”. 😳😳😳
i remember when i was first getting into shortwave listing in these days, i heard this broadcast at times. i totally forgot about it over the years. back when it first appeared, nobody knew how to make sense of it. the prevailing theory was that it was just a jammer or troll since it would appear on amateur radio (ham) bands but they also didn't make perfect sense since it wasn't really on frequencies commonly used. of course, we also made up all kinds of obviously nonsense conspiracy theories (back when those were fun...rather than schizo political insanity) about it being a numbers station, with the audio clip specifically chosen to imply the US might get nuked or all sorts of amusing ideas. once everyone kinda figured out that it was just from some sort of research, it lost its mystery although it always remained a fun memory for people who were into radio in those days. this update video about it makes it even funnier now that the guy said he didn't even bother to consider whether anyone would hear it or care. well, now he knows just how far radio hobbyists - especially the hams - will go to when it comes to radio, especially something that was so unusual at the time :'p
Superb analysis, I wonder what kind of power they were putting out? LabVIEW and the associated hardware is incredible and very versatile, it's a shame more people don't use it to help improve their products and stop so many poor designs spewing out interference, surprised they would use copyrighted audio samples for test purposes in a professional scenario though 🤔
I kept waiting to hear this part of the report. The [pentametric fan] consisted simply of six hydrocoptic marzelvances, so fitted to the ambifacient lunar waneshaft that side fumbling was effectively prevented
I believe this indirectly solves the operation of modern numbers stations mystery, which might provide more insight on how to “decode” them. Just my own personal theory.
I watched the first video… i still don’t understand half of the words you’re saying in this. I’m probably just dumb, but i still enjoyed it. 🍿 I think the only initialism you used that i actually knew was gps…

Personally, I don't think side fumbling would be an issue because any competent radio engineer would undoubtedly be using prefamulation.
I think with all those modulation schemes they were testing the modial interaction of magneto-reluctance and capacitive diractance.
It all sounds a bit crudely conceived to me.
We don't know what it was for though.@@StubbyPhillips

5:16 first time i seen one of these in use - just built one for leo satelite use - i think the idea is omnidirectional circular polarisation... Kevin..
Well there ya go who'd have thought it
Great detective work Lewis
Mystery solved 👍
Great video.
Amazing the things that are in my backyard (60 miles to my Northeast ) Thanks for putting this out there 73s
Thank you, James Clerk Maxwell and Heaviside for sending us down an infinite rabbit hole.
Faraday deserves his due as well...amongst others.
I READ THE WIKIPEDIA PAGE WHEN THIS WAS EDITED BUT DID NOT BELIEVE IT WAS REAL.
That was a good video and really informative. But I don't know, man. One day, about eight or nine years ago, I saw a random RUclips video on abandoned missle silos around the U.S.A. that people were exploring and more than a few of them had painted pictures of Yosemite Sam on some of the walls and I have never been able to shake the annoying hunch that there might have been some connection between the silos and the Yosemite Sam numbers station mystery.
We used Agilent HPLCs in our chemical lab at BP Chemicals.
Does England use the 26.965 - 27.405 AM +SSB class D CB radio service along with their FM band?
Yes.
First it was pirate, but now it is legal.
Exhaustive!
Superb!
Well done - it was always good for a giggle
Hey bud! Will you please do a video on the Stock Bros trading wanting to use a portion of the HF Ham bands?
Thanks
Working on it
“System security and user monitoring are provided in two layers. Standard security measures such as a firewall to the Internet and ***Windows XP*** accounts provide the first layer”. 😳😳😳
It was 20 years ago lol
@@MrWhite2222 I know. I was using it in an enterprise environment back then. Hence my comment.
I naively thought Yosemite Sam was a strictly American thing. Looney Toons forever!
Were they licensed to transmit in such a large frequency range?
Do you need a license on a reservation
@@PapaWheelie1 it’s still in the USA
Guys, it was the government/ military doing the testing, lol. They gave themselves a permission slip.
i remember when i was first getting into shortwave listing in these days, i heard this broadcast at times. i totally forgot about it over the years. back when it first appeared, nobody knew how to make sense of it. the prevailing theory was that it was just a jammer or troll since it would appear on amateur radio (ham) bands but they also didn't make perfect sense since it wasn't really on frequencies commonly used. of course, we also made up all kinds of obviously nonsense conspiracy theories (back when those were fun...rather than schizo political insanity) about it being a numbers station, with the audio clip specifically chosen to imply the US might get nuked or all sorts of amusing ideas. once everyone kinda figured out that it was just from some sort of research, it lost its mystery although it always remained a fun memory for people who were into radio in those days. this update video about it makes it even funnier now that the guy said he didn't even bother to consider whether anyone would hear it or care. well, now he knows just how far radio hobbyists - especially the hams - will go to when it comes to radio, especially something that was so unusual at the time :'p
Superb analysis, I wonder what kind of power they were putting out? LabVIEW and the associated hardware is incredible and very versatile, it's a shame more people don't use it to help improve their products and stop so many poor designs spewing out interference, surprised they would use copyrighted audio samples for test purposes in a professional scenario though 🤔
in the video there was a reference to power output stepping between 100 and 500 watts.
Our very own Poirot! 👍😁
Great story, Lewis! I didn't ever copy this signal but was aware of it of course! Mystery solved! 73
This is really interesting, as a former programmer with a passing radio interest.
I kept waiting to hear this part of the report.
The [pentametric fan] consisted simply of six hydrocoptic marzelvances, so
fitted to the ambifacient lunar waneshaft that side fumbling was
effectively prevented
Very cool!
I wonder what the customer used it for when it went into operation - and not doing mere test signals
Wouldn't these kind of transmissions be illegal? Seems like if a ham tried this the FCC would ticket them.
Yosemite Sam and the Dragon. This wins the Nobel prize, the Oscar and the Olympic gold for cartoons.
Wouldn't have been quite as interesting if Yosemite Sam wasn't somehow involved. 😆
And he had no idea that the signal was even getting out or that anyone was listening.
At least they didn't use "Porky Pig"...
I don't know which would have been worse to hear at that that time, this, or "that's all, folks!"
They could have used old Bugs Bunny since he was always taking a wrong turn at Albuquerque... "Eh, what's up Doc"
outstanding work, I'm an armature and really appreciate the technical details.
Now,
Had he been in on the whole thing,
The thing for him to do would be to pause Yosemite and read off a list of numbers on regular intervals
I believe this indirectly solves the operation of modern numbers stations mystery, which might provide more insight on how to “decode” them. Just my own personal theory.
Well done.
Very interesting!
Engineer Ambitiously, Lewis!
But why did the developer use antennas instead of dummy loads to develop the system??
What’s a real-world commercial reason for the scenario example described in the paper?
right, the text is just pages of blabla. LabView and cost effective...
Wow, Imagine being able to blast out garbage onto the airwaves with no push back whatsoever.
I was wondering about that. Surely they were violating FCC regulations.
@@DeronJ The station is on an indian reservation, that's probably how they got away with it.
@@DeronJ The government itself doesn't violate their own regulations - they can basically do whatever they want
bit like top band and 80 meters in the UK :D
The news media does it all the time...!
I watched the first video… i still don’t understand half of the words you’re saying in this.
I’m probably just dumb, but i still enjoyed it. 🍿
I think the only initialism you used that i actually knew was gps…
So since the transmitter is on a Indian reservation, does the FCC still have authority there?
I think its Federal Land rather than State Land ?
@ottopartz1 More likely the NTIA...
this yosemite sound 🔥
What was the application was this used for though??
They're test transmissions to see how well radios mounted on military vehicles are able to receive them.
