The gigantic Blaw-Knox antenna is about 300 feet higher than the Washington Monument, rising 831 feet over the Cincinnati suburb of Mason.
A little brick building nearby sends 50,000 watts of power to the enormous diamond-shaped tower. At one time it delivered a massive 500,000 watts of power to cover much of the United States with 700 WLW's programs. It was and still is "The Nation's Station".
The studios have changed locations many times over the years but 700 WLW's signal has originated from the same place in Mason since 1928. Amazingly not much has changed there, as news anchors Brian Combs and Matt Reis discovered during a tour conducted by 700 WLW's chief engineer Dave Abbott on May 12, 2022.
In the video and photos below, we explore the heart of the Big One. We walk with the ghosts of station founder Powell Crosley, the engineers, programmers, producers, sales professionals, actors, disc jockeys, talk show hosts, news anchors and reporters who have served millions of 700 WLW listeners over the past 100 years.

I was able to hear this station on the Bonaire KiwiSDR the other night. Station has an incredible coverage area at night with little interference for thousands of miles in some directions. Great video!

My father told me that when WLW was running the 500k transmitter, the farmers at night didn't need to turn on the lighting in their barns as all the light bulbs just glowed.

Doghouse coils rectifying the audio. I had a friend whose grandparents lived nearby during WWII. They said they had a light in their barn that they couldn’t turn off when the 500kw transmitter was on the air. Too much RF. VOA was a flamethrower too.

Love the Big One. One of the best signals around Columbus 24/7, and I love seeing the tower coming down 71. Used to catch WLW at night for the few years I lived in Houston. Alleviated some homesickness for sure.

Amazing the early engineering that has lasted so long. Many bridges that have collapsed were much younger then this iconic tower construction.

Is this the station they used to call Truckers radio? If so i used to listen to it late at night here in middle Georgia and loved it.

I love these tours, been watching over the years and it's amazing to see how much has changed and how clean the site is getting, going to miss the cooling pond and all the pirex glass tubes in the basement broken, but it's also cool to see the inside of the fema boxes, which I'm guessing is an addition as it was not shown when kage was there or when the guys from the ham club toured it.

It’s reassuring to see the preparations for emergencies. I’ll have to make sure I have a suitable radio compatible with this system.

I was on a private tour of this facility back in the late 90s and quite a bit has changed within the transmission housing (somewhere I have some poor quality video) led by Mike Martini and whomever was the station manager at the time. Interesting to see all of the updating that has been going on the last 20 years. We did get a closeup look of the Blaw-Knox antenna, but that emergency management set up was not there then. Thanks for the video tour.

14:45 that's a nuclear fallout shelter. Most of the clear channel stations had them for national security, to keep them on the air and maintained. in case the ground level studio was destroyed or too dangerous to inhabit.

That tower is radiating tons of RF. Was it safe to be that close to it? I've seen other transmitter tours, and all the towers have fencing around them with signs saying keep out.

REALLY nice topic, I truly enjoyed this piece of history. Thank you guys for doing it. One comment though: how come all you elite professional audio guys couldn't do a better job on the audio? A minor nit pick, still a wonderful video.

Wow. Just wow. I hope to have the honor of seeing that in person someday. Question- Since those logs are still there, is there a log sheet showing the last time the 500 KW transmitter was on the air? I was told they kept it in operational condition through WW2. Curious if that is correct.
@guyintenn
@guyintenn 6 месяцев назад
From the Worldwide Dx Forums "February 28, 1939- WLW reverted back to 50,000 watts of power, ending the superpower experiments, except for the W8XO experimental license, allowing 500 KW operation between 12 midnight until 1:00 AM, which remained in effect until December 29, 1942."

@@guyintenn Thank you. Yes, I know all about that, but what I was asking is about a log sheet showing the last time it was on the air. In other words, an exact date.

Holy crap at 11:35 you leaned into an antenna switching unit that is LIVE ON AIR...? I would never consider going that close to it - extremely dangerous if it is on (which I guess it must have been). Why are there no safety interlocks on the doors to prevent people from getting fried? Also at 19:09 you get right into the antenna hut and wander around - did the CE not tell you that all that bare metal is LIVE and if you touch it, it can kill you? Also getting that close to the base of the aerial itself, which is live with probably close to several thousand volts of RF is incredibly dangerous. I honestly had a lot of difficulty watching this - when I worked in radio, we had special courses on safety and what to do if someone accidentaly touched a feeder and was electrocuted. What you guys were doing was very dangerous.

Yeah, I sort of thought that also. Especially standing just a foot or two from the base of the tower. An accidental touch could be fatal. I remember the vid with Randy Michaels and Art Vuolo and them getting shocked from their mic cable while standing just outside of the tower compound. All great to see, but scary at the same time.

At most broadcast stations, the base of the tower is the lowest voltage / highest current part of the tower. Lets say they had a base current of 25 amps, the RF voltage would be 2000 volts for 50 kW. The coax switch was running at 50 ohms, so 50 kW would be 31.6 amps and ~1600 volts. You'd have to get really close for it to arc over. Sometimes the RF components are in interlocked cabinets, sometimes they are in caged areas which may or may not be interlocked. The tower must be behind a locked fence. The RF components in the tuning shed are usually just mounted in the open. They figure if you go inside the tower fence or in the tuning shed, you know what you're doing.

@@timothystockman7533 - yes - so as I said - several (or at least nearly 2) thousand volts... enough to stop most peoples hearts and potentially burn out the nodes - if that happens NOTHING can revive you. Yes if you get inside, they assume that you know what you are doing - assumption is the mother of all f*ckups - and in this case it is very likely to be a fatal f*ckup. The very fact that anyone is getting that close to anything in a live Tx hut and leaning into the areas of maximum danger indicates to me that maybe the concept that you espouse is not evident here.

You aren't alone. This was a stressful thing to watch. Being a former broadcast engineer myself, there were a few moments that were just far too casual for me, but at least it went without incident.
