Wireless headphones transmitter circuit schematic

This wireless headphones transmitter assures a quality reception over 2 meters. The oscillator frequency is between 1750KHz and 3500KHz and for antenna we use a ferrite bar. IC1 amplifies the audio signal and TC1 is a buffer. D1 signals that the transmitter is on and is a voltage stabilizer for the oscillator .
L1 is a toroidal core T50-2 with 80 turns, 0.2mm Ø. L2 requires a 10-20cm ferrite bar, L2a has 3 turns, 0.6mm Ø coiled at ground end of L2b wich has 30 turns, 0.5mm Ø .
The current consumption of the wireless transmitter is <= 150mA and is to be used with this wireless headphones receiver.
