Added (marked) schematic, layout, pcb for SDR receiver. Added support for analog, DSP and SDR receiver back end, and auto detect hardware modification (including SSB mod). Fixed TX working again. Fixed TX on wrong frequency issue after reset. Added volume control. Added experimental AM, FM demodulator. Added s-meter support for DSP/SDR mode. Changed LCD writes for reduced RFI (RS changes remain source of interference). Added CIC up-sampler for audio output. Added power down. Added profiler for RX sample-rate control. Added attenuator.

Added (marked) schematic and layout.
...
Remove unused and experimental code.
Relaxed LCD smeter refresh rate (in order to reduce interference on RX).
Allow ADC/RX-TX setup times (wait long enough before enabling TX, and disable TX well before stopping ADC).
Added CPU benchmark for ISR processing during TX.
Added operational instructions.
Added performance measurements.
Cosmetic and usability changes.
