DIY Simple FM Transmitter | Spying bug

The range can be up to 20 meters after testing with obstacles, but you have to adjust the antenna on your Radio FM as the receiver. Inside a building without anything blocking the transmitter and the receiver.
You can change the microphone to 3.mm jack or 1/4 jack.

I was making them smaller than this in 1970. 1/4 mile range.

Sound like your are sending a message from moon , just kidding

[@pradeszebua]

Haha that’s okay man. Yeah it does sound like that, this is a low powered radio transmitter, some high powered ones transmit clear sound...

[@TheAdwatson]

The antenna is way too small for the frequency. To get a decent range you would need an antenna about 70 cm long and a ground plane, or a dipole 1.4 metres long.

[@pradeszebua]

Yeah definitely. But, that’s gonna make it look big

nice video

[@pradeszebua]

thank you

[@prayitnabangun2762]

bro can you help me? I have the same module, but the trimpot is broken. is there another way to replace that component?

[@pradeszebua]

I would suggest you to buy a new module but see if you can find that component called "variable capacitor"

[@pradeszebua]

however, I think it's really difficult to get it from local electronic stores, you'll have to find it online

[@prayitnabangun2762]

thanks, this is very helpful

Silly DIY. Your antenna is, like wrote @Allan Watson, is non to small, he is to long in device cover. So that so long antenna are for cca 150db, and if work to long and to near radio receiver will fry small el. elements in transmitter. YU1AHBBCBGD
