Melchior FRANZ: All necessary elements for an ADF gauge had been migrated from Cockpit/kr_87.cxx to Instrumentation/adf.cxx. Migrating the sound related elements was apparently planned, but not done yet. This intermediate state broke the ident morse sound: it couldn't get turned off and it always indicated "SF", regardless of the tuned-in frequency. The following patches continue the migration: adf-radio.diff => Base/Aircraft/Instruments/adf-radio.xml: --------------------------------------------------------------- * sets maximum volume to 1 (rather than 2); Not only is 1 loud enough (and 2 unpleasantly noisy), it also prevents the knob from being turned to non-existant positions. :-) * fixes wrong use of /instrumentation/adf/ident * the voice/ident selector(?) remains unchanged, but as it's not switched to "IDENT", there'll be no ident sound by default this is consistent with other sounds and DME. radiostack.diff => src/Cockpit/radiostack.[ch]xx: --------------------------------------------------------------- * comment out use of FGKR_87 class. kr_87.[ch]xx is now no longer used. kr-87adf.xml would no longer work, either, but isn't used anywhere, anyway. Future adf radios have to use the adf instrument, using xml/Nasal for specific hardware implementation details. adf.diff => src/Instrumentation/adf.[ch]xx: --------------------------------------------------------------- * adds ident morse sound capability using two new input properties: - /instrumentation/adf/volume-norm (double) - /instrumentation/adf/ident-audible (bool)
