    Hang on start

    Analysis
      * Added timeout value to extinguish status message

        - Tx - transmit aborted, return to Rx
        - Tune - tune aborted, return to Rx
    rigMEM
      * removed rigMEM support code

    WF only null pointer fix
      * in waterfall only mode, bypass text logging of rx stream
    RTTY config tab
     * Cosmetic corrections
    RTTY stop bits
      * remove forced return to 1.5 stop bits for Baudot
