FM transmitters

Two FM transmitters were built recently. The first transmitter is based on 7 2n3904 transistors: http://forum.allaboutcircuits.com/blog.php?b=517 The second transmitter is based on 3 2sc1740 transistors: Some resistors were made adjustable especially the emitter resistor and the bias resistors. Using other transistors than the originally suggested 2n3904, this is absolutely neccessary. The schematic for the second transmitter:

ベイブレード I have built an FM transmitter. Previsouly I have built an AM transmitter but it never worked right, only very short distance. http://cappels.org/dproj/FMXMTR/fmxmtr.htm The design is somehow finicky, and does not work like shown. Adjustable resistor for the 330 Ohms, and 1K Ohms are essential. As well, you need to tap the antenna with a gimmick capacitor. It only … Continue reading
