A VFO CONTROLLED 1.5 WATT 525-1725 KHZ AM RADIO TRANSMITTER
This is a very nice handcrafted AM full range tunable radio transmitter which is designed to broadcast music. The operating frequency range is 525-1725 KHz with VFO control and the output power is 1500 miliwatts. It's frequency can be adjusted by a special circuit and which performs very good frequency stability. This transmitter runs on 12 Volts DC. This transmitter is an enchanched version of my 525-1725 KHz 100 mW AM transmitter. 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 power source and a telescopic or wire antenna (a few meters long) to run this LW transmitter. A high power 100V 40A mosfet is used at the power stage to prevent any damage due to high VSWR when used with short, mismatched antennas. This unit is pretty sufficient for hobby use and mostly designed to use as a simple station for your antique radios.
