Overview
This chapter provides an introduction to the T6T transmitter, briefly describes the features, and
shows how the radio is configured for operational use.
INTRODUCTION TO THE T6T TRANSMITTER
Park Air Electronics (PAE) T6T is a VHF multi-mode air-traffic control transmitter compatible with
analogue (AM) and digital (D8PSK) modulation modes. Current models are supplied programmed for
AM voice operation in the frequency range 118 to 136.975 MHz using 25 kHz or 8.33 kHz channel
spacing. Future software upgrades will allow D8PSK operation.

AM voice operation in the frequency range 118 to 136.975 MHz using 25 kHz or 8.33 kHz channel
spacing. Future software upgrades will allow D8PSK operation.
The transmitter produces a 50 watt carrier output that can be reduced, in 1 watt steps, to 5 watts. The
output power, and the majority of operational settings, can be selected at the front panel, using the virtual
front panel (VFP) or through a compatible control and data system such as the PAE multi-access remote
control (MARC) system.

The transmitter is designed to be fitted in an industrial 19 inch (483 mm) equipment rack. Operation is
from either a standard ac mains supply, or from a low voltage dc supply. When both input supplies are
connected, the dc supply acts as a back-up if the mains supply fails.

Section 3.
Section 3 onwards will, when available, describe the digital operating modes.
A maintenance kit (PAE part number 70-6350MKIT) is also available. A maintenance handbook,
included in the kit, contains fault finding guides to module level and details VFP operation. The VFP can
be used for setting up, maintenance purposes, and for loading new software.

The maintenance kit includes a CD-ROM containing the VFP software and a lead for connecting the
radio to a Personal Computer (PC). The CD-ROM also contains the software as loaded into the T6T at
the time of sale. This enables the original software to be re-loaded if the transmitter's Digital Signal
Processing (DSP) module is ever replaced.
