Modified amplifier that can "wimp out" on very faint signals. Micro-USB charging port. USB-C (oval) charging port. Schematic Resources

: The "original" high-quality PCB is dated 2017-08-29 (Main RF board: MV02; MCU board: KV02) . Modified amplifier that can "wimp out" on very faint signals

: It utilizes the Si4735 DSP chip for signal processing. This chip is responsible for the radio's high sensitivity and its ability to handle multiple filter bandwidths (e.g., 500Hz to 6kHz for SSB/AM).
