Chapter 3 - Operation
This chapter gives the instructions for operating the base station after it has been correctly installed.
Users should note that the facilities available to an operator depend on how the radio's personality has
been configured.
INTRODUCTION
The base station provides transmission and reception on any 25 kHz, or 8.33 kHz, spaced channel
frequency within the VHF aeronautical frequency band between 118 and 136.9916 MHz. However, only
those frequencies and operating modes that are pre-programmed into the radio can be selected. The
radio can be reprogrammed at any time using the supplied software. Instructions for doing this are given
in chapter 5 starting on page 37.
Three operating modes are available: Normal, Priority, and Scan. In Normal mode, any frequency
programmed into the system can be selected using the radio's front panel controls. Priority mode is
similar to Normal mode, but allows faster selection of up to 15 frequently used channels.
In Scan mode, the radio scans a number of pre-defined channels searching for a ‘busy’ one. When a
busy channel is found, and depending on the programmed options, the radio remains tuned to that
channel ready for use. Scanning can be resumed at any time.

T6M Base Station User Guide
Page 17
When a T6M base station is received from PAE, the personality is either:
q
A personality programmed to the user's specific requirements.
or,
q
A default personality that covers the 760 channels (25 kHz spaced) available in the VHF
aeronautical frequency band. No frequencies are allocated to the Priority list, and no scan
groups are set.
A programming kit is available from PAE. This allows a new personality to be programmed and downloaded.
The radio does not have to be removed from its installed position to download a new personality.
Note that operation using 8.33 kHz channel spacing is not currently allowed within the USA.
