    Brief technical details

    This radio uses a BK1198 FM Mono/MW/SW DSP (U1) and a LTK5128D mono audio power amplifier (U2). The FM/SW RF Front-End uses a A7/BAV99 protection diode set (Q3) and a R25/2SC3356-R25 NPN transistor (Q2). 

    A CXKC14B5C by A3 Media Player and MCU manages the radio. 

    The Power Supply uses a LTH7/LTC4054 battery charger, a 422P/LN1154B332MR-G LDO regulator, and a few control switching devices like J6/S9014 NPN (Q5) and M6/S9015 PNP (Q8), and a J3Y/S8050 NPN (Q1) for LCD backlight LED control.
