I might’ve been a bit optimistic on the range… I think it’s more like 10 to 15 feet. Definitely designed to be as close to the radio as possible, which shouldn’t be a problem in most cases.
that's literally the only question I had lol. I went to leave a comment to get an answer and ..bam here it is. look forward to every video. great channel! thanks man.
Don't feel bad... as even when using a household/building-wide antenna system, for wireless broadcast of RF video signals, the effective range is surprisingly short with even the most powerful consumer-level antenna add-on signal boosters employed.
Walmart sells a FM transmitter that carries around 25 feet. It takes two double A batteries. I plug it into my phone and play music over the radio. I also plug into my CD player and play music on my car. Car has a CD player that went out. Q
My first car, which I got in 1982, was a 1972 AMC that only had AM radio. I used an AM transmitter in the car, attached to the headphone output (very low) of a cassette player. Later in life, I figured out what you are doing now- giving new life to old tube radios. Excellent video!
I built an AM transmitter as a Radio Shack educational Mod-U-Kit back around late 1960's. Really cool and these kits were a big part of getting me interested in electronics. The kits were pretty basic and not high audio quality but it worked. And at that time it cost (I think) around $8-10. Pity Radio Shack isn't around any more to foster young imaginations.
I remember those too and I built the AM transmitter in the book that came with the kit. It too didn't have much range. The signal dropped off on the little pocket radio I had, the moment I would walk out the bedroom door.
Great video! I have an AM Transmitter and an FM Transmitter and use them to play my music library from my laptop to my radios. I pulled the trigger on the AM transmitter after having an antique RCA Globe Trotter recapped and serviced and wanted SOMETHING to listen on it other than political talk, sports talk, religious talk! I looked at the model you reviewed here but opted with with that could cover my entire house and not have to have the radio right on top of it.
Above all, vintage CB/HAM radios and antennas are a passion of mine. The 60/70s were a wonderful time: grand CB parties, free from smartphones and Instagram profiles. Happy-2025 and best 73 to you and yours...
THis is REALLY cool! I've been looking for something like this. We have a couple of old tube radios from the 1940s/1950s that still work, and we've always wanted to play old radio shows through them (like The Shadow, Inner Sanctum, etc).
We surely need a blast back to the past. All AM has on it nowadays, is talk 👄 shows. Radio 📻 was so much better 😌, back in the 1970's. It was such a pleasure to turn on the radio, and sit down to an evening ball game 🏑. It would be so cool to broadcast as if it's the 1940's. Your friend, Jeff.
I was just imagining recording a list classic Christmas songs with myself as an old time DJ, pretending it's 1958.... without telling my guests... then have a call in segment where I pretend to talk to my parents who've called into the program to make a request... How long can I go before someone catches on?? LOL... Thanks for introducing this product... It definitely brings out the radio ham in me!
Never really had a problem I go to 530 in the area Cuba is found on I also find casual music. ha ha. It's in a area about a mile away. So I'm ok hihi. If I cover my lot.
There’s no need for worry, these transmitters are FCC part 15 compliant. Part 15 is a provision that allows license free low power short range transmitting devices.
This is something I have been looking for! I have a few vintage radios that I would like to play music through. Now if I could just get them working again :) This device would also work well in a vintage car with an existing AM radio. You could play oldies from your phone and listen like its 1965! Or 1975...
That AM transmitter is really cool, Record-ology. I bought a portable battery-powered FM transmitter for $12 about 25 or more years ago from a dollar store, but obviously, an FM transmitter would be useless for vintage radios from the 20s, 30s, 40s, and 50s which is why that AM transmitter you demonstrated is such a great gadget. :)
I do basically the same thing. I have an old Microsoft Zune loaded with period music and old radio shows plugged in to a "Talking House" AM transmitter. I'm not sure how many watts it is, but it will broadcast well enough to receive the signal out in my garage or in my driveway, or back yard, not to mention all over the house. I like to use it on my antique radios for that nostalgic feel. They have them on ebay starting at around $65.00 and up. I do also have a small "pocket size" transmitter, but it almost has to be sitting atop of the radio to get good reception with it. I find that on my console sets that there is usually room on the shelf that the chassis sits on in the back of the radio to set the small unit on and I can just put it's little antenna wire on the fahnestock clip on the radio. Both of my units are equipped with wall warts for their power supply, though the small one can be run on 1 9v battery.
I've seen these before. It is a neat way to get use out of vintage radios. One use case would be to be able to transmit music from my audio rig to the old AM receiver I have down in my basement workshop. I may have to look into this.
My first thought was "I wonder if there is an FM equivalent?" The transmitter certainly looks nice and appears to work well. I wrote this before the video had finished and you answered my question. An FM transmitter demo would be interesting too.
Nice you made this video. Im getting one. Just what I need to test my crystal radios that I build. The radio stations here are spotty sometimes. With this device I can check them right away. Thanks for the info.
I have a spitfire am transmitter (FCC approved) and a collection of old radios (even before WWII) and it's way more fun to listen to old records this way than any way else. I like to compare it with a fireplace and central heating ;)
Hey I have one of these (a slightly older generation of same product found on Ebay), and it works great! It's nice to play what I want on my old radios without having to modify the radio!
I have an FM stereo module on my PC that sends my sound all through the house and even the small yard. I can listen to podcasts and go lay down and turn on my clock radio and follow the podcast all over, portable radios filling in here and there.
You can stream music or whatever to a classic audio system with this device. This will be awesome in classic cars. You can possibly go to a car show or cruise. And play old music on AM radio, if someone can't hear it that well they can turn on their radio to hear it! Maybe add a better transmit antenna to it the device. To get maybe 50'-100' line of sight. That would be great. Maybe connect a linear amplifier to it used on cb radio, broadcast to a small town 😂... maybe get you in trouble? ✌️
Some of the weird noises are because it was off frequency, as well as possible front-end overload (signal was overwhelming the receiver). When on frequency and with good signal strength, AM can sound just as good as FM or direct audio in
I do something similar, I have a talking home transmitter connected to a raspberry pi, I use music on console which I can control from my phone. Something amazing about broadcasting your content
With the Studebaker CD player, the best cd to try would be Pink Floyd’s “The Dark Side Of The Moon”, as many of the songs flow into each other. Or even CD’s by The Moody Blues (1967-1972 era albums) for the same reason.
You can add a 160 meter ham radio amplifier & boost the signal & get up to 10 miles of range or more but you need to use a proper antenna. AM radio is great at night as you can hear lots of foreign stations as well as pirate radio broadcasts around 1620-1700 kHz. -Cheers!
Now for an AM Stereo transmitter! Yes they made stereo AM radios. I still have my old car radio from the late 80’s that has a stereo AM receiver and yes there was a station in my home town that was AM stereo.
Recalling a video about playing 78's with as modern of needle-in-groove equipment possible, one wonders how rich in sound... and with warmth... playback of these songs would be using such a method in conjunction with a hybrid reproduction system, and speakers of contemporary design & materials.
No problem finding a blank spot on the dial, there are no AM stations left on this island. Only thing we receive is QRM from the sub standard power grid.
A slightly better procedure is to tune the radio to find a quite spot on the dial and then find it by adjusting the transmitter. It is also possible to transmit more than one station. This can be good in an old car or the like where you may not want to fiddle with the signal source.
Several years ago on the Antique Radio Forum they had a number of plans for AM transmitters but using tubes. I ended up building one that used a 6GY6, but mine was heavily modified as I wanted to use it not only for entertainment but also to double as a piece of test equipment. It's got frequency response far in excess of even the best AM radios and you can hear it throughout the entire house, not just a few feet away. I also bought some 6888 tubes to build one of the other circuits but haven't gotten around to it yet. I figure if you're going to broadcast to tube radios why not use a tube transmitter to go along with it?
Sometime back, I bought a cheap-o "no name" record player, FM radio, and USB player that will play content from a USB thumb drive. I could load a USB drive up with songs, plug the line out jacks on the record player into an AM transmitter, and the record player will play, at random, the tracks from the USB drive through the transmitter. Like many other areas, AM is nothing to write home about anymore, and something like this transmitter is a good way to feed desirable content to an old radio without having to modify the radio. About the only good I get out of AM is WSM and a station at 530 out of Cuba that plays "beautiful music." Of course, both of these can only be heard at night.

another use case is those waterproof shower radios. Listen to audiobooks/podcasts streamed from the phone and broadcast to the shower radio. The catch is, what if your phone has no 1/8” output jack? These AM broadcast units could (should?) have a bluetooth receiver built-in to facilitate getting audio out of BT-enabled devices, all-in-one. Is there a way to attach an antenna to extend broadcast range (within FCC regulations, of course)?
those transmitters are cool the range isn't the best but the sound quality is good i like to use my talking house am transmitter with my cheap tube amp and cd changer hooked up to it to listen to my vintage radio shows on my restored 1939 zenith console radio and my other sets
Thanks for another great video Just curious but have you reviewed the Victrola Montauk Bluetooth record player looked through your past videos and couldn't find it if you made one
I was on a whatnot auction last year. This lady showed a box full of old radio and tv glass tubes. I bought them from her because she said she’d throw them out if no one bought them. I couldn’t bear for her to throw them out. Do you know anyone who needs old radio glass tubes?
Just a quick question: Does the input to the transmitter combine the left and right channels of the output from the source? Or are you just listening to one channel? I suppose the audio you’re listening to was all mono anyway but what happens if you have a stereo output?
Hello. Do you know where i can hookup my pico 2204A scope leads to get the am signal off the circuit? I built one of these on a breadboard about 8 years ago with my 8 year old son. It worked great. Just a modulator, audio transformer and 9V DC at a fixed frequency and audio input. Thanks.
You need to hear AM stereo broadcast, received on a capable radio. It sounds amazing! Look up shango66 for his interview and tour of AM broadcast station, WION AM stereo, it’s truly amazing and is broadcasting as I type this :)
If you really wanted to be immersive, have a few of these transmitters going at different frequencies, then you could scan through the dial like you would have decades ago.
Just get one of those illegal 7 to 25 Watt FM transmitters to broadcast a better pirate radio station. But who the heck still listens to AM or FM? It's all about Internet radio streaming in todays world. It's so easy to get started with Internet broadcasting, and it's FREE!!! I broadcast 10 internet stations and get an average of 5000 listeners per day. But in my case, I actually conform to the RIAA rules and pay royalty payments so the artists get paid for their work. My costs are relatively cheap per song, and I have a system where I can accurately calculate the royalties. But it's actually really easy to get away with this without paying anything at all. But my ethics prevent me from not paying royalties!!!
AM is mostly for voice, not music. The audio bandwidth is 300 - 4500 Hz, and there is no stereo capabilities. An FM transmitter is more suited for music, with a bandwidth of 100 - 12,000 Hz, with stereo modulation. You can't build a stereo FM transmitter - even if it is only 10 mW output - with three small transistors; you need a synthesized quartz oscillator, a stereo modulator (which creates and modulates the 19 KHz sub carrier), and one VHF output stage. This is more expensive than the device you showed in the video, which use a free oscillator and has no separate modulator (it can't modulated deeper than 50%).. Thank you for the nice video. Greetings, Anthony
AM radio had far better fidelity than that back in the day. WLW used to have a transmitter that was good for at least 50Hz to 20kHz. Nowadays the FCC has limited it to 10kHz to limit interference to other stations since there are so many more on the air, but even that sounds pretty good if the radio has a wide enough response.
I might’ve been a bit optimistic on the range… I think it’s more like 10 to 15 feet. Definitely designed to be as close to the radio as possible, which shouldn’t be a problem in most cases.

So long as it wouldnt bring the FCC to my door, I’m on board with this!
The FCC has a yearly budget of about $17, so I wouldn't worry about it.
Never really had a problem I go to 530 in the area Cuba is found on I also find casual music. ha ha. It's in a area about a mile away. So I'm ok hihi. If I cover my lot.
There’s no need for worry, these transmitters are FCC part 15 compliant. Part 15 is a provision that allows license free low power short range transmitting devices.
As long as you don't add an RF booster amp, so your mater down the road can hear, you should be good
With that low power, I am certain it is legal. The FCC allows up to 100 milliwatts from one of these transmitters.
I built the same one from a kit. They are brilliant.
This is something I have been looking for! I have a few vintage radios that I would like to play music through.

This is great to simulate the sound with its noise in historical movies! 💝
True!
Add a simple 4 channel mixer to your AM transmitter and you can have a full-blown radio station complete with mics and music inputs!

Old Sirius and XM radios pre 06 had some powerful transmitters, then the FCC stepped in.
No problem finding a blank spot on the dial, there are no AM stations left on this island. Only thing we receive is QRM from the sub standard power grid.

Many old cassette players weren't stereo
Most likely combines the two. There really was such a thing as AM stereo, but it's not common anymore. It was big from the mid 80s to mid 90s.

You wouldn't necessarily need to hook it anywhere on the transmitter. Just a few loops of wire around the transmitter should be good enough.
Who did you hire to write and sing that Record-Ology jingle?! Peace.
Another use case for this could be getting a clear signal from Internet feeds of a.m. radio stations.
Some countries would need that transmitter to be licenced.
With a range of just a FEW FEET?
as long as the signal doesn't leave home premises.
Play "War of the Worlds" and receive it on a 1937 Philco
Gotta admit, I haven't heard AM described as 'high fidelity' in decades, lol.
You need to hear AM stereo broadcast, received on a capable radio. It sounds amazing! Look up shango66 for his interview and tour of AM broadcast station, WION AM stereo, it’s truly amazing and is broadcasting as I type this :)
I would try it with an 8track tape player.
If you really wanted to be immersive, have a few of these transmitters going at different frequencies, then you could scan through the dial like you would have decades ago.
Check out the FiiO DM-13.
Coming soon!
Amazon says they are "Currently Unavailable. ".
They might be out of stock… Sometimes they come back with stock later… Also, there are several similar units on there
In the Uk low power Fm transmitters are legal. But not low power AM transmitters. Be careful
In the US nothing really is legal but the FCC doesn't tend to act on just random signals that are weak.
Review the Micromitter
Thanks. IMO the future is AM. AM digital with ECC.
👍👍
Don't you mean Quarter inch Mini Jack???
It's 3.5mm. 1/8th inch is a close approximation.

That's wacky, a CD over AM to a 50s radio. Cool.

Why is everybody ALWAYS saying LAD when it should be LED ? And no, my hearing is not impaired
AM is mostly for voice, not music. The audio bandwidth is 300 - 4500 Hz, and there is no stereo capabilities.
An FM transmitter is more suited for music, with a bandwidth of 100 - 12,000 Hz, with stereo modulation.

And get arrested like it's 1930! That's probably what would happen in the UK anyway.
