    gKit 32. TWO STAGE FM TRANSMITTER This Kit is a powerful two stage‚ 9V FM transmitter (Tx) with a range of up to 1 kilometer in the open. It uses an RF transistor in its output stage. Distance of transmission is critically dependent on the operating Conditions (in a building or out on the open)‚ type of aerial used (single wire or dipole)‚ operating voltage (12V is better than 6V) and if the circuit is peaked for maximum performance. The kit is constructed on a single-sided printed circuit board
