The battery supply rails have been well tied together with respect to radio frequencies. The tracks are also thicker making the fm transmitter circuit a single ‘solid’ block eliminating RF currents in different parts of the circuit. This also means the battery no longer has RF on it which makes the whole unit a lot more frequency stable. Can be tuned anywhere in FM band - DIY Kit 18.
Specifications:
* L: 1-3/4″ W: 7/8″ H: 1/2″
