Need a crystal controlled 6V or 9V powered FM transmitter(no SMD). This will be used to transmist a dynamic mic or guitar signal to a power amplifier. Range within 100m is OK. Preferably frequency within FM commercial band(87,5MHz-108MHz) but can be outside (up is better).
It can use discrete components PLL (4059, 4060, 4013, 4046, etc). No ASIC PLLs like SAA1057, MC145152, etc..
