While I agree with Tim that we won't divulge what we did, I will say that on the radios I measured the new settings improved IMD DR3 typically by 7-8 dB and as high as 16 dB on certain bands and preamp settings.  This was comparing the before vs. after on the same radios.  We also improved the ADC overload conditions so that there is no distortion on the in-band audio when the ADC is fully overloaded at +20 dBm.  Above this the reverse power protection kicks in.  I tested this myself.
