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!

You sir are the reason why I love youtube: original, interesting content based on science. Thank you. You gained a subscriber.

FM transmitter is something we really need in our phones... We never know when it's useful.

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!

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.

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).

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 LOVE YOUR CHANNEL.

MAN I HAVE NO WORDS HOW BADLY I CRAVED SUCH CONTENT.

[GadgetAddict]

I never knew there were phones with built in FM transmitters. Very interesting!

[GowrishankarLeGrand]

Amazing video! Found your channel yesterday. I'm really liking the niche and quality content, keep up the good work!

I have been an amateur radio operator for a very long time, I don't really do SSTV but know about it. Thanks for the video! Keep it up!

[stoojinator]

Transfer rate is on par with my NBN connection. Thanks, Malcolm Turnbull!

your channel is a gem. i just recently discovered it, and every video i've seen amazes me. thank you so much.

[MuhlisErtugrul]

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!

[bank]

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

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

[KRAFTWERKK]

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.

I love that album! I’ve never heard anyone talk about it! Good video!

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”
