KM Long Range FM Radio Transmitter. This long- range FM radio transmitter has an additional RF power amplifier stage, after the oscillator stage. The extra RF power amplifier used to strenght up the power output to become 2. With a great matching multi- element Yagi antenna or 5. The circuit designed using transistor T1 (BF4. VHF oscillator. A varicap diode circuit is included to change the frequency of the transmitter and to provide frequency modulation by audio signals. The output of the oscillator is about 5. Transistor T2 (2. N3. 86. 6) forms a VHF- class A power amplifier. It boosts the oscillator signals” power four to five times. Tronics Car Radio Frequency Converter. JK from FL, USA It was very easy to install didn't even take 5 minutes Operated perfect even in the United States. 4.298,00 Prezzo offerta . FM Tuner Frequency Range: 87.5-107.9 MHz in 200 kHz steps or 87.5-108.0 MHz in 50 kHz steps.Thus, 2. 00- 2. 50 milliwatts of power is produced at the collector of transistor T2. Here the coil winding specifications: L1 – 4 turns of 2. SWG wire close wound over 8mm diameter plastic former. L2 – 2 turns of 2. SWG wire near top end of L1. For humfree operation, operate the transmitter on a 1. V rechargeable battery pack of 1. Ni- Cd cells. Transistor T2 must be mounted on a heat sink. Do not switch on the transmitter without a matching antenna. Adjust both trimmers (VC1 and VC2) for maximum transmission power. Adjust potentiometer VR1 to set the centre frequency near 1. MHz. For better comes about, build the circuit on a good- quality glass epoxy board and house the transmitter inside an aluminium case. Shield the oscillator stage using an aluminium sheet.
