Note for FM1310
* C4(0.1UF) has to be close to IC pin 9
* Y1(32.768KHz crystal) has to be close to IC pin 16
* Place an GNDRF parallel next to the RFIN(pin 13) trace, and try to make sure they are the same length.
* L2/L1/L3(Bead) must stay close to the ear bug socket.
* Volumn and seek switch must have separated 100K resistor, can't share this.
