I built a fm big from a kit back in 90’s, an organisation called “talking electronics “ magazine released kits monthly, I remember this thing had a range of nearly a kilometre on 2 AA batteries, loved it.

Built my first 3 transistor transmitter over 50 years ago, using old 60s germanium transistors.The internet is amazing, I done a few searches and found the actual circuit I built, can't remember the magazine it was in though.

In the US, these are legal with 100mw or less power and 1 meter or less antenna. They are very popular in AM for people to use their restored antique radios to play old music or drama.

Brings back memories of me and my mate's when we where about 11 building a Hartley Oscillator and Transmitting am with it, we also found we could do Morse code on it and that increased the range to about 10 Times...Great fun using bits from old broken Transistor radio's.

Well fred what a great spy kit me and my next door neighbour talk to each other with our listing device p.s I've just ordered a camera pen

[RosssRoyce]

The tecsun tried to Feel Collins at one point 😛🤪 Nice review vid👍👍👍

[GaryMcKinnonUFO]

lol, you could have taken the radio in the car! Liked and subbed :)

[radiosification]

I think the FM broadcast band doesn't start until 88 MHz, that's why you couldn't hear any other stations around there

[DrWatts-bijv]

UK 🇬🇧 broadcast frequencies are 87.5 - 108MHz my friend.
Japan if I remember correctly, is 73 - 92MHz 🤔
Too many years developing prototype car radio. It's frazzled my brain 😂

[ibanez]

I have a different one, from Amazon. Mine was also tuned for ~96Mhz out of the box. Using them for a spy workshop.

Hello. I 've also bought several pcb modules of this kind but the compensator screw goes out and then moreover I don't have optimal listening performance. Annoying burns during 'listening. I have decided to buy a F-908 but have not been able to use it yet since I am not interested in applying headphones but instead a 'speaker so that I can record via smartphones, digital recorders, etc. But I am just now getting a 3.5 to 2.5 adapter for the jack. That's all for now.

Interesting video to use as spy device use around 110 mhz off fm band and receive on cheap scanner build into something maybe mains power with short covert range bigger the item longer the aerial with in reason no need for batts

[clarefabula]

LOL "for a bit of a crack" those of us in the US:
Uh... wut?

[nathanw]

There's no filtering on these things. I tried one, and it's just pumping out harmonics all over the place.

[digitalmediafan]

Hmm nice one seems the range is comparable with those low power legal FM transmitter devices

[michaelblucher]

Hey bro! Thnx for a cool chanal. Mayby it will work with the radio on the smart phone, there is it possible to tune in on any station. See you. Mic from Denmark.

[davideddy]

Just waiting for him to ask the dog — ‘What’s the frequency Kenneth?’

[jp-umfr]

What a nice young fella me lad you are. Bought 2 of these and 2 cheap transistor radios. Idea is that I'm fed up with pushing buttons on a walkie talkie and hopefully the old dragon and I can argue about who's going to have a headache tonight whilst I mess about outside and she's cutting her toenails with my new wire cutters. Do you think 9V would be better and what length aerial would be best ? Just finished a quad bench power supply 2 x 9A 0V - 38V linear (can be paired to give 18 A), 1 X LT1083's 8A?(4 off in parallel) linear and a big buck. Weighs a ton. Why? no idea but it's fun init.

CBOT wrote me on your channel but I don't see it (I only got the email notification. here is his message : "The spy ones usually operate on lower frequencies so they can't be picked up by a typical radio channels. I think you can go on Amazon and find them." My response : Okay, but I can't place them anywhere (since I can't get into other people's houses and don't have someone who can...) and I have to look for some solution, maybe a directional microphone with a dish and a trivial class D amplifier would be enough. I can hear by "naked" ear and I can hear my neighbors plotting against each other and sometimes I can understand some dialogue. Could you advise me on how to build a properly made wall microphone ....? I just don't want to dwell too much on this topic. Thank you very much. Hi.

[pierpa_pierpaolo]

I wanted to ask if it is possible to detect the fm frequency of a nearby bug? I live in a two-family house and I am afraid that my neighbors use one pcb of these for ex. in the living room and the fm radio in another room ... . I intuit that they are talking about me (in the distance, very low volume ...) but unless I have tangible evidence to record I can't nail them!!! Clearly this is an environmental version (it detects voices, noises from a particular room, office, etc.) I hope to be able to detect the empty frequency (I choose an empty freq., move the pcb closer to the small radio, adjust the variable pF and then I want to test all the empty freqs) to see if I get what I have in mind. For the time being thank you very much.
