Why RC toys still operate in 27Mhz band?
Recently I had opened an remote control (RC) toy to see its circuit and found that it operates on 27 Mhz. Not just that toy even many toys operate in that 27 and 49 Mhz band. These days we find even a small circuit utilizing UHF(300-3000Mhz) band then why these toys are still stuck in that frequency?
