10-15 Watt TFM Broadcast Transmitter
A very rugged and easy to use mono FM broadcast transmitter designed for 24/7 operation under less than ideal conditions. Unlike the cheaper Chinese transmitters, this unit features an external heat sink for increased longevity and reliability. An internal 13.8 volt power supply manufactured by Meanwell allows for either 110 or 220 volt operation as opposed to generic wall wart power supplies used in many Chinese made transmitters. Frequency range of 88.1 to 107.9, set by an internal 8 position DIP switch. Output power level is adjustable with an internal trim pot. Audio input is mono, high impedance, line level with an RCA input connector. Wide range audio response with low distortion. No all-in-one FM transmitter ICs are used. Instead, a fully discrete PLL circuit and a shielded low phase noise VCO made by Minicircuits are to used for the FM frequency synthesis and modulation. This ensures a very clean signal without spurs, a common issue with Chinese transmitters.
Also don't forget your antenna and coaxial cable.
