A 1.5 WATT TUNABLE AM MOSFET RADIO TRANSMITTER FOR 800-1200 KHZ
Here's a very nice handcrafted AM broadband tunable radio transmitter which is designed to broadcast music. The operating frequency range is 800-1200 KHz with VFO control and the output power is 1.5 Watt (1500 mW). It's frequency can be adjusted by a single tuning knob which controls a BB112 tuning diode. This transmitter is an enchanced version of my tunable low power AM unit which offers more range and utilizes 5 transistors. You can connect the AF input (modulator input) directly to a casette player, MP3 Player, Ipod, PC sound card, mobile phone or CD player's output and you can listen your music on your AM radio whatever if the radio is old or new. Also you can connect a microphone preamplifier if you want to transmit your voice. It operates on 12 Volts DC (DC power supply operated) (power supply not included). You only need a good quality DC 12V power adapter and a telescopic or wire antenna (a few meters long) to run this AM transmitter. A 100W 200V RF power mosfet is used at the output section to withstand high VSWR levels due to random type mismatched antennas.
I am an experienced radio receiver and transmitter builder, constructing radios and transmitters for more than 40 years, so you can buy confidently.
Features:
Covers most of the AM broadcast band (800-1200 KHz).
Tunable on any desired frequency within it's coverage.
IRFP250N power mosfet as PA stage.
BD139 AF power transistor as modulator stage.
2N2222 transistors as oscillator.
2SC2314 transistor as RF driver.
2N3904 transistor as high gain audio amplifier stage.
Compact lightweight design.
Operates on 12 Volts DC 300-500 mA.
Easy to setup and operate.
Very stable and high-performance unit.
I am shipping the unit via registered mail and the shipping cost is 19.95$ to anywhere.
