Display CTCSS tone freq in Audio, Recon, and Level apps (#1231)
* Generate CTCSS messages at fixed rate regardless of tone freq * Generate CTCSS messages at fixed rate regardless of tone freq * Function for generating CTCSS description strings * Function for generating CTCSS description strings * Increase width of CTCSS text to include tone freq * Increase width of CTCSS text field to include frequency * Use CTCSS tone freq when saving HAM freqs to freq file * Use function in tone_key.cpp for displaying CTCSS string * Use function in tone_key.cpp for CTCSS descr strings * Use function in tone_key.cpp for CTCSS descr strings * Clang test * Clang * Clang * Support for reading CTCSS tones from FreqMan file * Clang * Clean up and eliminate floating point * Clean up and eliminate floating point * Corrected CTCSS field length * Corrected CTCSS field length * Clang
