I find it strange that a radio which uses DSP directly from the IF for 
demodulation would use RF clipping or compression, or even analog audio 
compression. I would have thought that this would be done using DSP in 
the TX IF, or perhaps DSP on the TX audio before the balanced modulator. 
I would also expect the built in speech processing in a cutting edge 
technology, top of the line transceiver, to be so good that no 
improvement could be gained by using any outboard speech processor.
