As a radio technology enthusiast, something like this intrigues me to no end. SSTV technology is over 50 years old at this point and people still use it in 2023, not only for image transmission on shortwave, but for stuff like this!
It even works with baby monitors and grocery store walkie talkies if you are wondering as long as it's NFM or SSB but other modes could work too but the digital ones wont
"like that time i recorded video onto audio cassettes" Instant sub midway through the first video ive seen of yours. Looks like youre into some neat projects man, glad to be here to see it.
I actually never knew what were the radio noises in Portal until I googled it and found they were coded images. I immediately downloaded the MMSSTV and tried to make my own images. 😄
Used to record the SSTV audio codes onto a music cassette tape to send digital images to my friend who didn't have internet back in the late 1990's. I also would call his landline and play the audio over the phone for quickness if we were talking about certain photos etc. He used his PC mic to the phone/stereo speaker for decoding the audio. The funny thing was, we could still chatter on the phone while the SSTV audio was playing at the same time with no degradation of the image. Amazing stuff!
hey janus, idk if this is weird or not but there's a quality to your videos that just draws me in so much. you always have these little pockets of vibes that i just get lost in every time. it's strangely mesmerizing. kinda like 3:17. they just keep me coming back. your videos are just strangely artful and i love them, keep on making great content
@@JanusCycleI believe you are the exact opposite of Dankpods, by watchibg your content i actually get to know something. Dankpods makes videos without actual information about the things he records about.
Qualcom and Broadcom wifi/Bluetooth chips usually came with radio circuitry, tho not all phones had the radio feature because added circuitry was needed for radio to work, some added the circuitry to get the full potential of the chip, and some didn't bother(like apple).
Similar to this, phones also used to have an IR blaster. Instead of downloading mostly shitty apps to control your tv, you could use a universal app to control everything. It was really a great feature, I could control the TV the AC and even the garage door. I had a lot of fun using it, and also messing around with tv-s in waiting rooms and such. Really unfortunate that as technology advances, older but still very much relevant stuff gets phased out so quickly.
I think u live in the US so don't know about xiaomi, most of their phones always have ir blaster to control everything, and mine also has ir, in my family, almost no one uses the original remote
I'm glad you enjoyed this. It was less about correct radio techniques and more about exploring different technologies, in different ways to learn about them. I'm pleased that people with different backgrounds are getting something out of it.
Nice job yo! I have a FM transmitter device leftover from my father that's about 20 years old but still works. Guess it's time to search for it in my storage boxes and try this. Thanks for the high-quality content, mate!
Based on this video there is no reason why anyone should pay for SMS, the government should provide free FM radio SMS service and boost up the amount of towers as it travels farther. That way you can text in an emergency.
I remember my old Nokia X2-02 had a radio transmitter and used our big speaker FM radio to listen to music from the phone. This was before the Bluetooth speakers becoming common. It was a pretty good feature. NB: The phone had a built-in FM antenna, so it doesn't require a headset to listen to FM Stations.
I still think FM transmitters are way superior than Bluetooth. Especially older Bluetooth standards that still double-compress everything to MP3 instead of lossless.
We got the same phone. This phone was my older brother daily driver and sound transmitter. He always tune it to combo audio tape radio boombox (i think that it was called). Still work but lended to my uncle as his replacement phone some time ago so i don't know much
I do this on pmr446 while messing around two smartphones one running sstv encoder other robot 36 and it works surprisingly well even with the phone speaker screaming down the microphone of the transceiver
I love stuff like this. Fallout really got me interested in the idea of rigging up small infrastructure systems like local radio stations, Intranet systems etc with "junk" tech. I imagine in the world of Fallout they could use SSTV to send out Wanted posters to bounty hunters or survival guides to settlers in the wasteland via a radio station.
I think all phones should have an FM transmitter and receiver. I’d much rather use a built in FM transmitter in my phone to listen to music in my car or other radios rather than finicky Bluetooth. That would be super useful cause it could turn basically any old radio into a “Bluetooth speaker”
I had no idea FM transmitters were available on a phone, it's like the time I learned about some phones having Infrared receivers not just transmitters, so you could actually record infrared signals and replay them (with the transmitters).
@@JanusCycle If you do please look into making it possible for others to do. I would love for a device to exist that can record and replay infrared signals. It's a very underutilized area. We often have old infrared remotes lying around and no real way to use them. Imagine if we could! The other reason is that while there are still smartphones that have infrared transmitters they almost always don't have receivers and we are stuck with what library of devices is part of the remote app, and if you device isn't there you are (more or less) out of luck depending on how common the device is. I know infrared devices are falling out of favour. But they are still useful in my opinion.
@@jackkraken3888 i used irplus and android tvbox. There were option to use another remote to wake the box and when i used it, it were showing amlogic code that could be translated to WINLIRC_NEC1 so i built whole remote in irplus. There are irplus audio if you device lacks ir blaster.
What you did kinda reminds me of creating a Beep Map that hides images in audio and making it become visible with a Spectrograph. The artist "Aphex Twin" did something similar in the track "Windowlicker" at the end of the track.
FM transmitters were really cheap and easy to find, that uses the 3.5mm audio jack as the input, so no need for a phone that can do FM Transmitting anyway
I got an award from NASA and Roskosmos for receiving high quality SSTV images from the International Space Station in commemoration of Roskosmos' founding date anniversary.
The slow scan tv is almost as old as time or tv. Back in the 1920 they had an idea of being able to download pictures and even watch video over telephone lines. Back in that day everyone had a circut phone connection so they could run high quality music low resolution tv. Or picture transfer at decent rate. All systems was set up, then the cras of 20s came, then the war, then after the war, people was not thinking of that any more. Still a few video phone lines was built. Later also 6Mhz video phone lines was built that is what was used for live coverage of global events in the 80 and 90s.
Damn love this! Inspired artistically by the sound it makes and the pretext that all you need is a transever make me wonder if my home Audio room to room broadcasting would be easier to solve by radio rather than bluetooth
honestly old cell phones make REALLY good FM radios. got full stereo and even surround sound depending on the model. heck even super old phones you can take the batteries out and charge them outside the device like some radios.
i always love this kind of stuff, where you make werid ways to get something. been using some of them for story ideas, like this one where hidden clues are round in endless loops tapes being played in the background somewhere.
I have an fm transmitter that connects to the audio output on my rasberry pi running a media server including Spotify.... Doing Multi-room audio with old radios is so satisfying.
As a young radio enthusiast i wouldn’t find an fm radio in my phone boring. It’s that mindset or the radio in your phone being “boring” is what’s killing FM radio.
I never knew how important something as basic as radio is until I was too broke to pay for ppv football and realised I don't have a radio to listen to the free commentary, never thought I'd be pissed about not having an FM receiver on my phone
I still use FM Radio and I believe every single phone should have an FM tuner! Like, come on, there's no excuse. I know that Xiaomi even includes an internal FM antenna with some phones, allowing you to use the radio without headphones!
Great video, very interesting. I remember my Nokia N8, back when I was holding out from the iPhone/Android take over. I vaguely remember using that FM transmitter.
I let out an audible chuckle when I realized what photo you used 😂😂 this video inspired me to figure out how to get FM on my Samsung Note 9 and turns out Samsung makes a stock FM tuner app for certain markets. So I just download the APK cloned the app with an app cloner and installed it. Works just like it would if I bought it in South Africa.
It's sad that phones don't have fm transmitters anymore(?). It was a great feature especially in the car if there was no possibility to use Bluetooth or aux.
Hi. Some years ago I had the idea of creating a lightning detector for android using the built in radio receiver on a device, long story short - could not find an effective route. Your video has given me some new impetus for one of my create-an-app-every-month-of-2023 challenge. Thanks
I still have a black Nokia N97 that my dad gave me when I was younger when he changed phone, it has an FM transmitter and I clearly remember putting it next to radios to send sound lol
I still have Nokia n8, working perfectly fine than my newest flagship phone and even has better quality video and photo capture than any of the phone i use today, Amazing. More than 15 years have passed. Lot's of memories in it.
Damn bro the audio quality it's amazing especially with headphones. Also, I kinda wish I saved all of my old phones, your collection is impressive mate
Wow !! This is so cool !! I will try this I also have a small FM transmitter device. Will see if that can be used instead of mobile with FM transmitter
I can Transfer from my Nokia N73 to my Sony Xperia XZ1 Data with Bluetooth, but for sending a picture from my IPhone 14 pro, I need a fucking app tp send a picture to my Sony.... My N73 even has an infrared port!!
my first time having a FM radio was actually a standard radio but later i got smartphones that have a enabled FM radio one brand of smartphones i have is Motorola on some models
On why manufacturers don't always include an app to use the FM tuner - I heard that in the EU, a regulation states that any device with FM tuner capability is required to also have DAB tuner capability. I think it was a response from a manufacturer when asked why the radio app is present in ROMs for China but not in global ones (or along the lines).
2:18 Actually i guess, the "antenna" necesity is not only physical (the chip is inside so even fm broadcast woudln't be too strong to get there), but the app is rather checking if there is a resistance change on the audio jack, am I right?
It's probably easier than resistance change. Audio sockets have a physical switch inside to turn off external audio when something is plugged in. Plugging anything in, even a rod of plastic is likely enough to activate the switch and turn on the radio. But without much reception because no antenna.
@@JanusCycle Ahh that makes sense, since this is the case with any audio jacks. I always thought that FM antenna is just inside the case, but not under the gsm radio shielding ofc. I always regarded this as a kind of producer's imposition.
Рік тому
My friend's Samsung can receive FM radio with a pair of Bluetooth headphones, LOL. It's just a silly software check.
Am I wrong here in thinking the FM radio isn't a required part of this you could just play the audio from the speaker of the silver phone and the black phone would pick it up and decode it yeah?
Sstv for HAM radio. Basically you can use any radio transceiver for that as they decode digital image into analogue audio. I did try using 2 android phones and 2 cheap FRS walkie talkie radio and they works. GMRS with higher power will be able to send image even further.
I have known older phones had built in FM radios but I never knew there was software that could take the signal and then transfer data over the FM radio
Well you could connect both devices using a 3.5mm jack, but in a way that audio output from one goes to audio input (microphone) from the other. Then use an app that plays data as audio and another app that decodes microphone audio into data.
FM transmitters, IR blasters, headphone jacks, all technology which would still be very useful today but instead it's just endless iterations of camera sensors.
The part of running the FM receiver app to receive the SSTV image is misleading. The receiving phone just hears the audio from the speaker of the 'transmitting' phone.
Same tech used by the military without the crypto keys, we’ve been able to do this for the last 37 yrs. It’s not new or groundbreaking. You should setup the SMS function that it can also do. Then figure out how to make a weird mesh network that we’ve also been using for the last 33 yrs based on the same tech. I love it when people see things for their first time and then find out is been improved by leaps and bounds.
There's a reason why it's not advertised. It gives Samsung a reason to get rid of it and then once you complain, they're saying... Well it's not false advertising since we didn't advertise it in the first damn place. This is exactly what happened to Cellular band switching. Samsung devices used to let you do that until July of last year when they decided to get rid of band switching all together, and no one can claim false advertising since they never advertised it.
As a radio technology enthusiast, something like this intrigues me to no end. SSTV technology is over 50 years old at this point and people still use it in 2023, not only for image transmission on shortwave, but for stuff like this!
Frankly... it's a surprisingly easy way to turn every FM radio in the house into a speaker for anything you hook up to a small FM transceiver.
That's sad to hear.
Here in Brazil we still have AM and FM radio + 2g and 3g service
Is that what all those Ham operators do?

FM transmitter is something we really need in our phones... We never know when it's useful.
It was very useful in cars when Bluetooth or AUX were not options. Too bad phones don't have it anymore.
@@jk8557 Yeah and another thing I hate about newer cellphones is not having easily replaceable batteries anymore .
It will likely never be useful in a life or death situation because the signal will never be strong enough to go any meaningful distance

I did try using 2 android phones and 2 cheap FRS walkie talkie radio and they works.
GMRS with higher power will be able to send image even further.
I have known older phones had built in FM radios but I never knew there was software that could take the signal and then transfer data over the FM radio
Wow, this is really amazing!
Well you could connect both devices using a 3.5mm jack, but in a way that audio output from one goes to audio input (microphone) from the other.
Then use an app that plays data as audio and another app that decodes microphone audio into data.
BT as kid was magical
Don't know why I didn't think of SSTV when I clicked on the video. I find it so interesting!
FM transmitters, IR blasters, headphone jacks, all technology which would still be very useful today but instead it's just endless iterations of camera sensors.
This sstv format is really blowing my mind. Must’ve been difficult to make sure all the pixels are received
bro phones back then be havimg fm receiver and transmitters but new phone dont even have music jack
this is really new for me and interesting
It's a shame most phones don't have FM transmitters, it seems more convenient than fiddling around with Bluetooth in a lot of cases.
I remembered that there are many auto Bluetooth transmitters available, so to add transmit functionality to any android phone you could use it.
You can use a Bluetooth fm radio transmitter
The part of running the FM receiver app to receive the SSTV image is misleading. The receiving phone just hears the audio from the speaker of the 'transmitting' phone.
I made sure the speaker volume was silent on the transmitting phone.
Nice to see more that collect phones..:).....
Same tech used by the military without the crypto keys, we’ve been able to do this for the last 37 yrs. It’s not new or groundbreaking. You should setup the SMS function that it can also do. Then figure out how to make a weird mesh network that we’ve also been using for the last 33 yrs based on the same tech. I love it when people see things for their first time and then find out is been improved by leaps and bounds.
There's a reason why it's not advertised.
It gives Samsung a reason to get rid of it and then once you complain, they're saying...
Well it's not false advertising since we didn't advertise it in the first damn place.
This is exactly what happened to Cellular band switching.
Samsung devices used to let you do that until July of last year when they decided to get rid of band switching all together, and no one can claim false advertising since they never advertised it.
what about the new ones like snap 8 gen 3 esp w/ different countries that has laws that require them to not hide it vs other phone brands
