Add more SSB microphone gain for better quality (when speaking further away from mic). Add CW intermediate feature, to decode unfinished CW symbols. Add improved CW decoding with more fair weighting bewteen dash/dot timing. Add error message to check PTT/key and not shown in straight key CW mode when mic is pulls down DAH line. Add experimental WB2CBA QUADBAND, PE1DDA USDXDUO support.
