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: [e-mail]
Thanks
