Frequency Selection
T6 radios operate with 8.33 kHz and 25 kHz channel spacing. The radios recognize frequencies entered
in ICAO format and automatically adjust to the correct channel spacing. For multichannel operation up
to 100 preset frequency channels can be stored in the radio for immediate recall; any combination of
8.33 kHz and 25 kHz channel spacing can be stored. Any valid operating frequency can be selected from
the radio’s front panel or a compatible remote control equipment.
Operating Parameters
The transmitter’s operating parameters are set using the front panel multi-purpose Scroll/Select switch,
or by using the Park Air Virtual Front Panel (VFP) software in conjunction with a Personal Computer (PC).
Virtual Front Panel
The Virtual Front Panel (VFP) software supplied on CD with the radio is compatible with any PC or laptop
running Windows 2000™ or Windows XP™. The VFP allows changes to a radio’s settings and channel
information, it displays the current BIT state, displays BIT history, allows security locks to be set, and
provides maintenance facilities. A typical VFP presentation is shown in Fig 2. Using the VFP has several
advantages over setting a radio from the front panel; these are:
❑ A profile of the operational settings and channel information can be created, stored on disk, and
then recalled to download into other radios.
❑ A print out of the radio’s profile can be made from the VFP.
❑ The front panel controls can be locked. Front Panel Lock is available only when using the VFP.
