T6T 300 Watt VHF Transmitter Page 19 Overview
Operating Parameters
The transmitter’s operating parameters are set using the drive assembly’s multi-purpose Scroll/Select
switch, or remotely from suitable control equipment. Additionally, the Park Air Virtual Front Panel (VFP)
software can be used to set up the transmitter.
Frequency Selection
The transmitter is a single frequency synthesised radio that can operate with 25 kHz and 8.33 kHz
channel spacing. The radio recognizes frequencies entered in ICAO format and automatically adjusts 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. Valid operating frequencies can be selected from the radio’s front panel or a compatible
remote control equipment.
Virtual Front Panel
The 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 5. 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 printout 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.
