[@BigCar2]

My experience of these things in the day was awful audio quality. I'm guessing today we don't have anything else analog competing on the 900Mhz band.

[@Techlifeandmore]

Maybe still if you're in an urban environment but yeah cordless phones have largely gone away. These days there really isn't a lot of constantly transmitting stuff that uses this band, we still have the Z-Wave and Lora wireless technologies which both are pretty popular actually but they only transmit data periodically. Nowadays it's mainly the 2.4 GHz band but that's actually where digital is good because it can ignore interference easier.

[@fungo6631]

Don't cell phones have a 900 MHz band?

[@Techlifeandmore]

@@fungo6631 I believe that cell phones and cellular networks use the 868 MHz band in the United States.

[@charlie_nolan]

@@fungo6631yes, but different frequencies

[@charlie_nolan]

Mostly, because there’s so much digital in 900 MHz now so it would probably add all sorts of annoying noises into analog 900 MHz devices. Also, anything analog in 900 MHz needs to transmit at least 500 kHz bandwidth, so that doesn’t help for interference.

[@toastangler]

Whenever I was a teenager and cordless phones were in the 900mhz range, I could hear my neighbors conversations on my World Band radio. It was fun 😂

[@dstroma]

Houses in my neighborhood were a little spread out so I didn't hear many but I will never forget the conversation I heard where the dad was scolding a young girl about not giving him a phone message. "Do so and so call today?" "Yes" "Did you tell me he called?" "No" "When people call for me you have to tell me!"

[@fungo6631]

That radio was of shitty quality. I imagine the audio quality too (unless they used AM). I have a 1970s West German radio with shortwave and it doesn't suffer from the same interference out of the shortwave band.

[@toastangler]

@@fungo6631, It was in the mid 90's. I was 14 years old. I wasn't really concerned with the quality of the second hand world band radio that was gifted to me by my dad. I just thought it was neat that I could hear voices in other languages, and pick up cordless phones 😀

[@shellac4682]

Excellent posting and you're correct about the sound. There's an even earlier wireless precedent: in the 40's they manufactured record players that could transmit the signal to the AM band of a radio, not unlike the FM transmitters that were around for a while (and maybe still are) and required you to tune to a certain frequency.

[@jamesslick4790]

There are still (88-108 Mhz Broadcast band) FM transmitters around. I got one off of Amazon last year to use in a 1977 Buick with a factory AM/FM Stereo radio with no cassette deck (and obviously no "AUX" jack...). My desire is to keep it all stock. The transmitter is tiny and has a built-in 3.5mm cord. I use it with an Mp3 player. Works good!

[@MrDuncl]

Some of the 1980s Sony record decks sold in Japan had built in FM stereo transmitters. Illegal in the U.K. back then though. It wasn't until the iPod became popular that they finally allowed very low power transmitters.

[@lenbeedle]

I had the more basic version of this exact unit. I didn't have the speakers. I used it to transmit music from tape out on the upstairs stereo to the aux in of the downstairs one. I actually soldered a 4.5 volt adapter to give the receiver permanent power. It sounded amazing for its time.

[@xaenon]

[@shmehfleh3115]

These suckers were not cheap when they were new. As I recall, they sold for a couple hundred bucks, back when a couple hundred bucks bought a lot more than it does now. As a side note, I had lots of fun eavesdropping on neighbors' analog wireless phone conversations. All I needed to do was turn my own wireless phone's handset on, then unplug the base.

[@Alabaster335]

I had a scanner in the car, I would drive through town with the scanner on "Close Call" so it instantly picked them up. The 30MHz (I think the frequency was back then) had a lot of range on them too, some I could hear nearly 1km away.

[@charlie_nolan]

The nerd in me wants to see you get a huge 900 MHz antenna, put it out with your other ones, and test the range of this thing. 900 MHz has great building penetration.

[@Madness832]

About 17 years ago, I had a set of 900MHz analog headphones (from RadioShack, if I remember right). And I also had a 900MHz DSS cordless phone. I don't ever remember the latter interferin' w/ the former.

[@collectingonthecheap56353]

I remember seeing these advertised in various magazines and fliers. I never had these wireless ones, but do remember having some Recoton speakers and felt like they were fine for use in a bedroom and didn't expect them to be used to broadcast to an audience in an auditorium. These actually still seem to work quite well and as advertised.

[@mdavis5826]

Thanks for the video! Really love these older solutions for home audio systems!

[@xaenon]

This is actually very clever. By using a simple RF receiver, it allowed Recoton to use off-the-shelf computer speakers and headphones in their package (no need to engineer anything special!), as well as allowing for the end user to easily upgrade those items.

[@mr_ice117]

Reminds me of when i got my first fm transmitter back in my teen days. The cheap ones that run off of 2 AAA batteries. I was able to modify it to transmit a signal strong enough to be heard down the block. Of course i only had it on a few times to avoid getting in trouble but it was badass that it was possible. RF has always fascinated me, how it moves through the air and interacts with walls and antennas. The different ways of capturing and tuning into different signals... so many possibilities

[@deebeenine]

Some of these RF systems are able to transmit digital audio as well. I had a video/audio transmitter with cinch in/out a few years ago and was able to transmit PCM and even Dolby Digital audio from one room to the other via the video sockets.

[@nortenorancio4884]

This is genuinely more practical than any bluetooth headphones I've owned

[@Gunbudder]

i have a wireless RF playstation 2 controller from around 2003 or so, and its incredible. it was made by logitech and to this day it is still the best quality RF device i've ever used. it had insane power and range and ran for weeks off of 2 AA batteries. every other wireless device was line of sight IR at the time, so this thing was like space age magic. even modern devices don't come close to how well the controller worked. i suspect that is largely because the RF space is completely blasted with devices now though

[@wmalden]

I had the Advent brand of this technology. I had a speaker in almost every room of the house and an outdoor portable speaker. It worked well for a few years but the system began to be plagued by bursts of random static, I have always believed the static was caused by smart meters which came after I deployed the system. Eventually, I abandoned that system for Apple Airplay via AirPort Express which I still use to this day.

[@HazewinDog]

This is true space age technology. I had no idea this was possible this early in time. Very cool! Plus... I vould use that extended range. The range on new Bluetooth headphone only seems to get shorter over time...

[@nykwynes]

I have a pair of RF headphones from years back. They were a budget model that operated in the 49 MHz range and was mono! But it was still convenient to listen to music all around the house while doing various tasks on multiple floors. Range wasn’t bad. Couldn’t do that with modern BT.

[@gatomatias1]

Beautiful, love old tech!

[@Kruton1122]

I had one of those IR audio transmitters you showed in that catalog only it wasn’t called “marriage saver” it was called something else, anyway, the thing actually did work really well, it didn’t need direct line of sight, only needed to be able to be generally around it. It was really good at picking up the IR. The only issue I ever had with it was it had constant white noise in the background, probably due to regular light interference.

[@Roxor128]

In my own experience with IR headphones, you couldn't sit in the sun and use them, as the IR in the sunlight would completely overwhelm the signal, giving you an earful of static. I also get the same issue with remote controls not working during the day in the winter because the living room is flooded with sunlight, so you have to go to about four metres from the device before it will actually pick up the signal from the remote control.

[@deepblueskyshine]

Well up to 2010s there were Philips analog wireless headphones with built-in receiver and rechargeable cell, not any different in appearance from regular 40mm cabled models - good sound, long range and walking beyond the range was preceeded by a typical "fm noise". Plus, there was a way to have several sets connected to a single transmitter without any kind of tuning - home/office radio of a kind. "Flying saucer" desing of this transmitter is a kind of fun - recalls memories of the times of Siemens' and Motorola's "shoe phones".

[@StuffJason437]

Yup! The modern versions of these basically have a tower that has a mono FM transmitter & microphone inside, and headphones with a built-in radio. Did you know that the mono transmitter inside the tower of the modern ones doesn't have a phase lock? This means that over time, they will change frequency on their own and cause interference with nearby licensed radio stations, without you knowing about it or being able to re-tune it without taking it apart !!. The headphones themselfs are wired in mono, the "Transmitter" tower is also broadcasting in mono and overall it's not worth £9.99 at any shop. I kinda prefer Stereo FM over bluetooth and I can tell the difference. Bluetooth is noisy when battery is low and FM is only noisy when signal is poor. I usually have a private home-made radio station for such things.

[@TheOriginalCollectorA1303]

Analog RF systems like these are still cool and definitely usable. Sure, things like Bluetooth can be convenient, but at least this is a really easy plug and play solution. Even IR wireless systems are cool, especially something like the Sony Laserlink! When it comes to something like iTunes, I do use the AirPlay functionality as it works great even on old devices like the iPad 1, iPhone 4, etc. It’s a good digital solution and definitely better than streaming/subscription nonsense. For physical media or an addition into a HiFi or Home Theater setup, something like this would be great to have!

[@briangoldberg4439]

omg The Wiz. I forgot about them. They only had one I knew of in our area and Circuit City was way more prolific

[@Earcandy73]

I have a Recoton set with better speakers but the same transmitter. Each speaker has a switch to pick left, right, or mono. The speakers sound fantastic but they static even when pretty close to the transmitter. The speakers have really heavy power supplies- 15 volts at 1.5 amps.

[@paulweston1106]

I've still got a set of those Sony headphones shown in the Crutchfield Catalogue; unfortunately the pads on the headphones have fallen apart but they do technically work and the base works fine. The base takes an Optical input and does a decent job of providing surround sound; I used to have mine connected to the DVD player as it was better than the surround from my TV.

Analog wireless was fine until something better came along.

I had this system back in the 90s and there was a lot of static even when everything was in the same room. Also the audio quality wasn't all that good, but my girlfriend like them just fine.

The signal is actually probably higher fidelity than FM radio. I don’t know if it was this way at the time, but now anything analog in 900 MHz has to emit a 500 kHz wide signal, or use frequency hopping. I have a background in 2 way radio so I am full of this useless info. FM radio is 200 kHz at most.

You've just reminded me of another Recoton set of speakers I owned in the early 90s. They worked by sending the audio signal through the mains wires to the two mains powered speakers. They were superb. As heavy as breeze blocks, the powered unit even more so, but better sounding than JBL Control 1s. Here in the UK they were being sold by Rumbelows. More known for white goods than hi-fi equipment, they started off at £120. Way, way more than teenage me could afford. After a few months, they went down to £40 because, like I said, most buyers came in for a fridge or washing machine. I could just about afford that and so glad I took the plunge. There was a decoder that sat near your source, connected by stereo phono leads and then to the mains. Then the two speakers. One plugged into the mains with the amp inside and the other speaker connected to that with black/red speaker wires. As long as it was on the same ring main, it worked flawlessly. After a couple of years I decided to make dedicated enclosures for the two speakers and a separate box for the amp and mains circuitry. Sounded even better. :)

Well these days 900MHz works well because fewer devices are using it. In the 90s and early 2000s when it was crowded with cordless phones and other wireless stuff, it didn't sound so good. Nowadays everything is using 2.4GHz but you don't notice it as it's all digital. But back in the 90s, you'd get maybe 100 feet before you could only receive your neighbour's audio or phone calls. These days, 900MHz is used by garage door openers, and smart meters. That's how clear it is.

It's still here today, in the three non-overlapping 2.4 GHz wi-fi channels and all the things that conspire to create interference because they too operate on those same frequencies! This many iterations later, one might think these things would be a bit better thought out by the standards bodies and various communication authorities. ("Yes, these things will get popular. Define more unique frequencies than you think you might need.") As a youngster, I well remember discovering that my father's scanner radio had no problem picking up the 49 MHz cordless phones we had at the time. Quite a while later, I learned that his newer scanner could also pick up our 900 MHz cordless phone, though that one employed frequency hopping while operating.

The infrared worked fantastic and had fantastic sound. The only problem was if someone walked in front of you. I still own a pair of the headphones. They also have a built-in AM FM radio . Over the years I have misplaced the sending unit.

I was ready for these to be junk but wow! Bluetooth could never go 70 feet. But also I guess 900mhz is rarely used.these days so very low interference.

[@buitreador]

oh boy...i still have the Sennheiser HDR100 i bought in 2007 to get rid of the cables. It operates in RF at 900Mhz and the base stops transmitting in 3 minutes if no sound is playing, then if you start playing something it wakes up with a 1 or 2 seconds of delay. It uses 2 x AAA batteries and was quite decent, often with a range capable of 30 or 40 meters. A funny thing with this headphones its that back in the day i could hear the cordless phone from my neib of the 1st floor perfectly when the base stopped sending signal (i was in the 2nd floor) but it only catches one side of the conversation. I used them for about 12 years until i replaced them with a bose bluetooth headphones in my pc at a comparable price ($150 now, 100 back in 2007), obviusly the bose wipes the floor with the RF headphones since there is no interference and the audio is clear (you had a dial in the HDR100 to tune with the base and was very finicky). Keep in mind that there was no bluetooth 2.0 devices in 2007 and that was not a thing until 2009 with the Motorola S9, so there was no other option.

You weren't kidding about the dynamic range in that example :) Also, the range of bluetooth really is quite bad.

1:18 What do industrial donut fryers use the 902-928 MHz band for⁇

[@imark7777777]

There was a weird gaming chair recliner thing for kids at Walmart. You are meant to plug your devices into it and it had speakers. Well apparently they also had a 900 MHz wireless transmitter kit I managed to find one somewhere it doesn't work nearly that good unfortunately it would've been very useful. I was also given two sets of wireless headphones due to not being used I got one and then later the other. It's a bad about technology and now not a lot is using 900 MHz these days, with people ditching their land lines less cordless phone usage and with baby monitors and security cameras going to 2.4 GHz for marketing reasons. I don't think there's a lot of stuff there these days there's certainly not as much as there was. Oh and I can hear 16 kHz I don't know if I've ever noticed an FM carrier though because I think most of the radio I have use filters.

[@Eddies_Bra-att-ha-grejer]

What's even the point of wireless headphones? Wireless speakers kinda make sense if you're having a party and you want to pass around the device that provides music so people can queue up whatever they like, but headphones are for personal audio and then you would pretty much always have the device close to you, usually on your body. It has always felt like some kind of stupid gimmick like wireless keyboards.

[@ObiWanBillKenobi]

RF is nearly always without exception better than IR. This product is an example of why.

[@RebeccaTurner-ny1xx]

I used to own a pair of Sony FM wireless headphones. The phones were lovely, with great sound and immense comfort on my ears. But the FM reception was dire, no better than a standard old radio.

[@shun0825]

your video have shown me how good this 4$ PC speakers I bought online 🤣🤣🤣 and it supports dolby atmos

[@VulpisFoxfire]

I remember All Electronics used to sell a FM transmitter that did much the same thing...I used them in combination with a radio/headphones combo.

[@devinsmith4790]

Speaking of radio, anyone ever heard of Sci-Fi Old Time Radio? Seems like a station based off in Livonia, MI (not far from where I live) and it plays what you expect from the name, classic Sci-fi stuff like Star Trek.

[@azoriusmage]

I used to listen all the time love the old Sci-Fi

[@devinsmith4790]

@@azoriusmage I discovered it via a site called Radio Garden, which let's you pick some stations via green dots on a Google Earth-like globe.

[@bluekewne]

I got one of the Sennheiser ones as a Christmas gift in 2007 - it would occasionally pick up people's phone calls on wireless handsets for landlines. Of course I didn't listen to any of their calls or anything.

sylvania used to sell some "wireless headphones" for your tv that used rf . I got some for christmas but the build quality of them were terrible.
