  Brief technical details

  The PCB assembly reference is "DE19.PCB  07.18".

  The design is based on a Si4734-D60 DSP IC by Silicon Labs. A basic RF Fron-end, using one J8 NPN transistor and one C3 pair of diodes for antenna ESD protection, handles the SW signals.

  A CD1622CB 2-channel/BTL audio amplifier IC drives the built-in 50mm 12 Ohm speaker.

  A HT46R64 MCU IC by HOLTEK manages the radio and drives the LCD, with the help of a ATMLH302 (AT24C08D) 8Kbit serial EEPROM by ATMEL/MICROCHIP.

  The power supply uses some additional active components to handle the battery charging, power regulation, and switching.
