BH1417F stereo FM transmitter is capable of broadcasting good quality signals over a range of about 20 meters and is ideal for broadcasting music from a CD player or from any other signal source so that it can be picked up in another location. L1 coil comprises 2. 5 turns of 0. 5 - 1mm enamelled copper wire (ECW) wound onto a tapped coil former fitted with an F29 ferrite slug. Alternatively, you may also use any commercially made 2. 5 turns variable coil.
