Please see our amazing high gain WiFi transmitter with an amazing 300 meters transmission range!
You can adjust WiFi RF power,WiFi channel,bass, treble and mids and lots more. Please visit:https://www.soundtransmitter.com
Buy me a coffee: I spent a lot of time on my videos on YouTube ,I have had this YouTube account 20 years ! and my recent videos I have built projects that are controlled by microcontrollers and need code to make them run ,the code takes a lot of time to get right and work well then I even share my code to anyone that wants it,I would appreciate a coffee if you can.

Lets make a very simple 2 transistor FM transmitter
In this video i will show you how to make a
FM Transmitter that is very easy to build and get working.
Frequency: 90Mhz - 108Mhz
Current consumption: 15mA at 9v
Working Voltage: 3v - 12v ,more Voltage more transmission range !
Stability: Not bad
Transmission range: Antenna 20.6cm= 100ft - Antenna 165cm= 800ft+ , Penetrates through walls and ceilings.
RF Power: about 8mW RF output
PLEASE NOTE
The videos I make take a lot of time to film and edit ,I know I don't make many videos and that I will improve on in the future ,any donations are welcome to my PayPal account at: dazaro@blueyonder.co.uk
Thanks
