#
# These are the helper functions for the kma20 audio panel
# Maintainer: Thorsten Brehm (brehmt at gmail dot com)
#
# Usage:
# just create one instance of kma20 class for each kma20 panel
# you have in your aircraft:
# kma20.new(0);
#
# KMA20 audio panel properties:
# root: /instrumentation/kma20
#    knob: microphone/radio selector (com1/2)
#    auto: selects COM1/2 based on microphone selector
#    com1: enable/disable COM1 audio (e.g. for ATIS)
#    com2: enable/disable COM2 audio (e.g. for ATIS)
#    nav1: enable/disable NAV1 station identifier
#    nav2: enable/disable NAV2 station identifier
#    adf:  enable/disable ADF station identifier
#    dme:  enable/disable DME station identifier
#    mkr:  enable/disable marker beacon audio
#    sens: beacon receiver sensitivity
