/Schematics/Radio transmitters/Super FM transmitter 2W

Quote: "Power of this transmitter is around 2W and range should be around 50-100km depending on the antenna and LOS component. Coil L1 has three pins, the second one is on the middle. Tuning is carried out with 13pF capacitor. Trimmer 25pF is for antenna tuning. Varicap diode can be changed with BC107 transistor. Potenciometer 100K is for NF modulation tuning. Operating voltage is 12V."

Ovakav redajnik sam pravio pre osam, devet godina. Kao predajnik ne valja nista, pun je harmonika, "gasi" SONY televizore itd. Dobar je jedino da se skonta sta je FM modulacija i kako to radi posto je koriscena varicap dioda. BTW nema toliki domet!!!
