Com Radio Operation 9. Com Radio Operation The SV-COM-X25, SV-COM-X83, and SV-COM-C25 integrate with your SkyView HDX system in a novel way, allowing you to “load” airports to it to enable quick, single button-push frequency tuning via the dedicated TWR, ATIS, GND, and ATC buttons. You can also send individual frequencies to your SkyView Com radio from SkyView HDX’s airport info pages.
Com Radio Operation COM RADIO Control Page SkyView HDX offers a COM RADIO control page for on-screen control of nearly all the functions available on the dedicated control module. Access the COM RADIO control page either by touching the Com enunciation area on the Top Bar, or selecting MENU (Button 6) on the Main Menu, then selection the COM RADIO icon. The figure below shows the COM RADIO control page.
Com Radio Operation Figure 241 – SkyView Top Bar Com Radio Status Overview Using your SkyView Com Radio Power The SkyView Com Radio normally powers on and off with your SkyView system. Press and hold the Volume Knob / Power Button to manually turn the SkyView Com Radio off and on. Volume Use the volume knob to adjust the radio volume. You may want to use Squelch Override – covered below, to aid in finding a comfortable volume level.
Com Radio Operation When receiving on the active frequency, the following indications are shown: Note the arrow on the top bar that points to the active frequency, and the up arrow on the RX area of the control panel display that points “up” to the active frequency: Squelch Override (Monitor) The radio has an automatic squelch function which screens out noise and only receives radio stations that have active transmissions on them.
Com Radio Operation When dual watch is enabled, the SkyView Com Radio monitors the standby frequency for transmissions while simultaneously monitoring the active frequency, allowing you to listen to both (but not simultaneously). This allows you to listen to ATIS on standby, for example, while keeping tower tuned to the active frequency. The active frequency always receives priority. This is true even if dual watch is listening to a continuous broadcast on the standby frequency.
Com Radio Operation • Turn the small, inner ring of the dual concentric knob to change the standby frequency. The SV-COM-X25 and SV-COM-C25 adjust in 25 kHz increments and by either 25kHz or 8.33kHz increments on the SV-COM-X83 (depending on how it is configured). o For example, if the frequency you start with is 123.450, turning the large knob will change the numbers before the decimal – 123 – while the small knob will adjust the numbers after the decimal – 450.
Com Radio Operation • With a valid Com frequency highlighted, (a 25kHz frequency on the SV-COM-X25 and SV-COM-C25 and an 8.33kHz on the SV-COM-X83) press the TUNE COM button to send the frequency to the standby frequency: • Press the dual concentric knob on the control panel to flip/flop the chosen frequency from the standby frequency to the active frequency.
Com Radio Operation This feature also works when a Garmin SL30, SL40, GTR 225, GNC 255, MGL V6, MGL V10, Trig TY91, Val NAV 2000, and f.u.n.k.e. ATR833 or Icom A210 (with Icom software version 1.53 or newer) is appropriately configured. The SL30 and GNC 255 can additionally receive NAV radio frequencies by selecting VOR, ILS and LOC frequencies (MAP > NRST > VOR > TUNE NAV/ILS/LOC). You can tune NAV frequencies from both the NRST list of VORs, as well as from the detailed VOR and Airport Info pages.
Com Radio Operation Use the TWR, ATIS, GND, and ATC buttons on the control panel to send the associated airport frequencies to the standby frequency location: By Airport Lookup • From SkyView HDX’s MAP page, look up an airport via SkyView HDX’s INFO page: • Press the APT>COM button to load the airport to the control panel: o Note this button is only available if SkyView has frequencies for the selected airport.
Com Radio Operation Loading Airports via the Control Panel By Nearest • Press the APT button once.
Com Radio Operation • Use the dual concentric knob to type an airport identifier. Note that this search is limited to airports within 75 miles of your location to speed up entry by limiting the airport possibilities: o The small, inner knob chooses characters (A-Z, 0-9). o The larger, outer knob moves the cursor: • When the desired airport is displayed, press the dual concentric knob on the control panel to load the airport to the control panel (or press APT to cancel your selection).
Com Radio Operation • ATC: When on the ground: Tunes pre-taxi, clearance, and departure frequencies associated with an airport. When in the air: Tunes departure, center, and approach frequencies when associated with an airport. As of SkyView software version 15.1, there is no longer filtering of ATC frequencies when on the ground and in the air. All ATC frequencies can be tuned at any time.
Com Radio Operation Waiting for Data The loaded airport area of the control panel will show an animating scrolling black cursor momentarily when it is waiting for airport data from SkyView: No GPS The control panel and SkyView top bar annunciate that SkyView does not have GPS position information in the following way: Without GPS position, airport loading, and TWR/ATIS/GND/ATC will not be available.
Com Radio Operation External Flip/Flop If you have an external flip/flop switch connected (typically to your control stick or yoke), pressing it flip/flops the active and standby frequencies just like pressing the dual concentric knob does. See the SkyView Classic / SE / HDX System Installation Guide for details on connecting an external flip/flop switch.
