       - 4-carriers of 62.5-baud 4PSK = 250 bps
       - 1/2 rate K=15 FEC with 4sec interleaver
     * OFDM-750F for HF SSB
       - survives HF NVIS/long path
       - 3-carriers of 125-baud 8PSK = 562 bps
       - 1/2 rate K=13 FEC with 3.2sec interleaver
     * OFDM-2000F for HF-SSB/FM
       - 8 carriers of 125-baud 8PSK = 2000bps
       - 2/3 rate K=13 FEC with 3.2sec interleaver
     * OFDM-2000 for HF-SSB/FM
       - 4 carriers of 250-baud 8PSK = 3000bps
       - NO FEC, meant for line-of-sight

     * DCD-OFF code now searches over 6-bit window
     * Prevents rare data-loss bug mid-transmission

   fmt
     * add callback handlers to
       . btn_unk_enable
       . btn_ref_enable
       . btn_fmt_record
     * reset frequency whenever ref or unk button is pressed

   Win32 Serial Port
     * change
       "if (!hComm)" to
       "if (hComm == INVALID_HANDLE)"

   CW punctuation
     * Allow user to suppress decode/encode of specific
       punctuation characters
     * Allow user to select character to display noise decodes
