I was stationed at England AFB in Alexandria LA in 1971. My home state at the time was Ohio. One night a bunch of us were sitting in the parking lot of the barracks drinking beers and listening to my car radio. The local radio stations had shut down for the night so I started tuning around for something else to listen to. Finally found a station coming in fairly well, and was astonished when they gave their call sign as WLW, a station I listened to all the time before my service days!

[@Alexagrigorieff]

The aliens’ receiver needs at least KT of energy to detect presence of signal, where K is the Boltzmann’s constant equal to 1.38E-23 J/K, and T is the equivalent noise temperature of the receiver. For the receiver with 10K noise temperature, it needs at least 1.38E-22 J per bit received. Suppose the aliens have an antenna as big as 1 km across, say it’s 1 km^2. Suppose we ignore atmospheric radio noise, too. 1 light year is 9.461E12 km, 84 ly is 7.95E14 At a distance of 84 light year, and a non-directional emitter, such 1 sq.km antenna will be getting 1.3E-31 of the total emission power. Thus, our receiver would be able to detect a signal of known shape if its energy was about 1 GJ. This is *ONE GIGA JOULE* per single bit of information to transmit at 84 ly distance. At the transmitter power 500 kW, it will transmit one bit per 2000 seconds. This also means, the minimum frequency of detectable amplitude modulation would be 0.00025 Hz at this power.

[@MrSparks54]

In my previous life as a broadcast engineer I briefly worked at KUSW shortwave station in SLC Utah back in the late 80s before it was unceremoniously sold to KTBN. The transmitter was a 100 KW Harris SW100 fed to a TCI log periodic curtain antenna pointed 70° towards Europe. The antenna gain put the ERP at around 1.2 MW. We got lots of signal reports from Europe of course but also got a bunch from down under off the back side of the antenna. The transmitter and studio were in the same building and upon firing it up for the first time, RF sparks flew around the steel girders in the TX room, scaring the crap out of everyone. A few rolls of heavy bonding straps later the RF sparking was cured but RF was getting into everything from the telephones to mic inputs. A few dozen RF chokes later and shielding everything, the station was ready to go into service. Meanwhile, engineers at what was (at the time) Hercules Aerospace across the street were freaking out that that much ERP could ignite their rocket motors. So engineers from Harris, TCI met with Hercules to assure them their rocket motors were safe even though the signal went right over the top of their facility at a fairly low takeoff angle. What a short but fun ride that was.

KWT-6 was the largest and only TX we had at my shop, and then a pair of R390's with cross squelch for WWV received supplied for telephone line feed hack with over 90K calls a year. One recv on 10mhz and the other on either 15 or 20mhz. Yes, that guy's "Side Conversation", ALMOST STARTED to take over! I Thought YOUR Guy was the one GIVING THE TOUR? with your other Friend? There has Always got to be some "know it all", and for that matter, how many people were listening to him? One or Two? RUDE! Surprised they didn't tell him they wanted to hear him talk instead the other hot shot, and not his "side-bar"! I would have said something to him. His speech sounded like he was giving it as a "hard of hearing" and also as if HE was the most important one in the room? Hard of hearing? I too have been a motor mouth and got reminded, bringing up history I knew. I learned to raise my hand to interject or ask if the presenter knew any of what I knew at important subject times. During breaks, I would confir and he would let me talk. I then wrote down all I talked about so he could add to his talk and also research my Truths! I kept them brief, so I had to learn to try and be quiet to hear first what I didn't know!...adding to my stories for others who may have never heard of either of our stories. Learning 'HISTORY' not speaking my own, has been very benefical. Lips flapping might get you shot with my or their BS. If you know who it was, I would suggest they listen near the last third/quarter of this video and show them the "attention" broken on your presentation by their very PRESENT VOLUME, which had an affect on your stories...Have them send me an email! I'll return one with a large Q-tip, with an address of "What does quiet mean?" I learned! After sending it back THRU HIS LEFT EAR TO THEIR RIGHT SIDE...maybe they'll get the jest? Obviously EMPTY HEADED, just a recording pre-made...lips flapping. Thanks...Great job, Got my 3rd Radar Edorsed in 1971 in Omaha, where I wound up at Offutt AFB, Later. Worked for KIOS FM, KVNO FM, and wired a TV STATION IN 1986 for stereo, WOWT. Never got my 1st, and haven't picked up my general now that it was is the norm? If you get a chance get on Tour in San Fran of Mt Sutro? Tower for Ch 4 & Ch 5 which SHARE A SINGLE ANTENNA WAVE GUIDE combiner TO THE TOP! AMAZING LOOKING COUPLET! Sometimes lighting takes it out. in 1982 dollars it was a $250,000 piece, bet its now a cool Million but not needing as much pwr with Digital, but bet it still reaches its old cir. of 100miles to East and South? Againn I was glad to come across your channel.

Thanks for a great video! I work on some big stuff in the service (so I thought). Thanks for the history lesson! I would have loved to been there!

[@aceiconia7215]

Absolutely amazing technology and know how for the time. It's insane how they guys built this and the knowledge they had was a testament to the time. Radio was less than 18 years old!

[@K7AGE]

This must have been a huge project.

[@paulanderson79]

@Mr MEMé Thank you. I took my spelling from a comment on his YT channel.

[@paulanderson79]

Far as I am aware, yes, he's still alive. He was having a bad time of things emotionally. He'd married an Indian lady (in India) and UK borders took exception to her coming here. It's eminently possible he's uprooted and moved to Asia. I wouldn't worry too much about his safety with electric stuff etc. The guy is a degree qualified electrical engineer. He knows exactly what he is doing.

[@RobertJochim]

Great job at documenting an important part of radio and broadcast history.

[@stephenburkholder9411]

Most of these cookies are on one self beyond my reach but I’m still fascinated. Not so much anymore but I was addicted to WLW in the nineties. Burbank, Bozo, McConnell, Cunningham, Jim Scott & Seg Denison.

[@J0HN3]

Thanks so much for creating this. Never knew this station existed.

[@dbingamon]

I used to have a telephone that picked up WLW, had to replace it because of it. Kings Mills Ohio

[@Brookside975]

Even up here in Kettering, we use to have a phone that constantly picked up WING 1410, who antenna was less than a mile away.

[@MWofOHIO]

Even in the 1990's, early 2000's, we could still pick up WLW on the telephone, especially just after your friend or family member hung up before you did.

[@vicodumb]

I live in Northern Iowa and if conditions were right, WLW would boom in here. Loved listening to Bill Cunningham at night when I was driving.

[@may4state58]

What a shame that the City of Cincinnati allowed the old Arlington Ave site to go into ruins. :( What a VITAL piece of American history! Not just the radio aspect... But the automotive and national defense history as well. Maybe on day... Someone VERY WEALTHY will restore the Arlington building to it's glory. But the City allowed it to sit sooo long... It would be an uphill battle.

[@tray-oq1nj]

Imagine the work and genius that went into developing every single piece of that huge operation.

[@christopherhulse8385]

500kw is an insane amount of power, although there are stations using 2000kw today in parts of the world!

[@DanTDMJace]

2 MW?

[@tuberadiohistory8093]

Very interesting look into great old radio transmitter. Thanks.

[@cups3]

When I was taking my electronics training 1978, and we had a lab were we were going to be actually working with tools, our instructor wanted us to realize this is the dangerous stuff. But he wanted to talk about it is the reaction to a shock that does the damage. He talked about working in big transmitters where you turned the power off , walked into a cabinet made a adjustment waked out fired it up and see if it was ok . He was working in a cabinet and the ding dong working with him forgot if he had actual flipped the switch when "power off " was called . So of course he just flipped it the other way. My instructor that was in the cabinet got zapped as he was reaching in past the sheet metal . He yanked his arm back. He took off his jacket and was wearing a short sleeve shirt so we got a eye opening shot of the long ugly purple scar running all the way down his arm

[@filter4now]

This is so amazing - I made my way back here again. It always brings to mind what was said to Don Luchessi at the end of the Godfather series - "Power always wears out those who don't have it..."

David, thanks. That must have been an amazing living breathing machine to be around when it was running.

[@Ahmed.45]

Sir, thanks so much for posting this! I love machinery and electronic gear from the 20's through 50's. Very impressive.

[@josephjames259]

Thanks for uploading. I was in Mason a few months ago. I took some photos of the antenna array from the parking lot of a Mexican restaurant across the street. My interest is from being a fan of host Bill Cunningham. This was a very interesting video.

[@kusgilb]

Fascinating. I love the technical side to this video.

[@THEBIGLABAROWSKI]

Great video! I've lived in mason my whole life. Grew up just a few minutes from the transmitter site. Looking up at that tower as a kid played more than a small role in my interest in engineering. Are these tours done on a regular basis? I would love to get in on that. Is any information available about the link from the Crosley building to the transmitter site? Was it just telephone lines? What's the story on the HMMPWV that's always parked outside?

[@Wdbx831]

Brings back memories - I worked as a co-op for Navy in 80's one job was to fix an old 50 kw transmitter amplifier that was converted to power a vibration shaker table. It was unstable. Somehow I got it working - had to design a phase adjust circuit on feedback.

Very fascinating Randy. I worked in broadcasting in my younger years and its something that gets in your blood.

[@rupe53]

I always look in awe at this older technology and wonder what it would take to put it back on line. Would it still serve a purpose in the big picture?

[@ralfoide]

Thanks for capturing this tour on video, very much appreciated all the details that were provided by the hosts!

I guarantee, my grandfather (K8NZW), would have LOVED the tour of this monster!! He was an electronics genius!

[@doncooper3946]

(@13:09) So - it took roughly 200 horsepower to generate the power JUST for the filaments! Wow!

[@stanspb763]

This is a great video, thanks for creating and posting it. High power was started there and a lot of new tech was used for the first time. What was not mentioned was the same people were involved in the rapid design and development of 6x 200kw HF transmitters and 24 rhombics that did not use the termination loads. This was part of the war effort. It was located just down the road from the WLW site. The modern design allowed frequency changes and direction changes in less than 10 minutes

[@ZoomtronicBlogspot]

SW radio station near Belgrade had 2MW of RF power, started emitting in 1930's www.rts.rs/page/tv/sr/story/21/rts-2/1076422/trezor.html "Objekat u Zvečkoj podignut je 1949. godine po ruskom projektu, antena visine 235 metara bila je oko 33 metra viša od tornja izgrađenog na Avali; predajnik je bio jačine 150 kw, početkom šezdesetih postavljen je predajnik jačine 400 kw, a kada je rađen aneks zgrade, 1974. godine, kupljen je predajnik od 2000 kw, a zamena starog učinjena je a da to niko nije osetio, ni slušaoci Radio Beograda ni svetski stručnjaci koji su odali veliko priznanja za taj tehnički izazov koji su više nego uspešno ostvarili naši inženjeri i tehničari. Glavni projektant bio je inž. Momčilo Simić, a inž. Mile Bogdanović je bio nadzorni organ za predajnik, kao i za posebano izgrađen dalekovod kod Mislođina i koji je nezavisno od mreže napajao predajnik u Zvečkoj."

Thanks and a big thanks to Jay and Geoff for their help in making this video. I will be posting another video about WLS's collection of 50,000 transmitters, stay tuned.
