- **Simple to install modification** with **8 component changes and 8 wires**

- **Lightweight and low-cost transceiver design**: because of the EER-transmitter class-E stage it is **highly power-efficient** (no bulky heatsinks required), and has a **simple design** (no complex balanced linear power amplifier required)

- **Fully digital and software-based SSB transmit-stage**: samples microphone-input and reconstruct a SSB-signal by controlling the phase of the SI5351 PLL (through tiny frequency changes over 800kbits/s I2C) and the amplitude of the PA (through PWM of the PA key-shaping circuit)
