Frequency

Mini FM transmitters take place as one of the standard circuit types in an amateur electronics fan’s beginning steps. When done right, they provide very clear wireless sound transmission through an ordinary FM radio over a remarkable distance. I’ve seen lots of designs through the years, some of them were so simple, some of them [...]

Parts List R1,R4,R6 = 10K, C1,C2 = 0.1uF, Q1,Q2 = 2N3904 R2 = 1M, C3 = 0.01uF, L1 = 0.1uH R3 = 100K, C4 = 4-40pF R5 = 100 ohm, C5 = 4.7pF R7 = 1K http://www.uoguelph.ca/~antoon/circ/fmt1.htm

Here is a small project about FM receiver that you can built with a little cost. The dificult point is to get the inductor coil, i think there a no electronic store that sell this coil.

Below i have finished develop a mini fm transmitter that work fine at frequency 88 – 108 MHz. Here is the schematics if you could not understand please feel free to comment here
