7. The software vovovox code can be used for fast complete control (qsk and semi-qsk operations) or RX/auxiliary switch TX to be used in digital mode (no cat or PTT interface is required)
8. The PTT/PA output is externally controlled by the all-digital tx-delay stage and the software-based SSB stage transmitter: the phase of sill SI5351 is controlled (by a small frequency change i2c at 800 kbits/s) and the PA amplitude is controlled (by a pwm pa key shaping circuit)
9. Software-based all-digital SDR receiver level (optional) : sampling of I/Q (complex) signals from a digital mixer with an orthogonal sampling detector, and mathematically perform a 90-degree phase shift (David Hilbert transform) in the software by adding an Atten sideband
10. Three independent switchable analog pushers (0db, -13 db, -20 db, -33 db, -53 db, -60 db, -73 db) from the front receiver
