Look what my beauty has become!

Until Now:
Channel range from -150 to 150 (I know radio filters will block most of negative channels. I'll think about that later)
Frequency and Channel Modes.
Electronic roger beep
Electronic Voice lock, 10Khz range, 100Hz precision on any band.

Planned:
Replacement of all caps and some diodes.
Radio input amplifier for small signals.
MOSFET based power stage.

It's still under development on weekends.
