2W FM Transmitter

This is the schematic for a FM transmitter with 2W output power that can be used between 85 and 110 MHz. Build the transmitter in a RF-proof casing, use good connectors and cable and be aware of all the other RF rules of building. Q1 and Q2 should be cooled with a heat sink. the 22pf variable capacitor is for the frequency adjustment. The another trimmer must be adjusted to maximum output power with minimum SWR and input current.

Note : Local laws in some states, provinces or countries may prohibit the operation of this transmitter. Check with the local authorities
