USB File Format

The TY96/TY97 radio internal database that can store up to 250 airfield frequencies. These are stored as an identifier (up to 6 characters), a standard facility designator, such as TWR or GND, and the station frequency. These database entries can be created, edited, and deleted from the front panel of the radio. They can also be saved to a USB stick and loaded from the USB stick.

The data file used on the USB stick is a standard format called Comma Separated Values or CSV, and the USB stick itself uses the popular FAT32 file system, which means that the file can also be edited on a desktop computer. CSV files can be edited using a simple text editor, or they can be opened by most spreadsheet software.

The Trig Com radio database is always loaded from and stored to a file called TRIGCOM.CSV located in the root directory of the USB stick.

Each database record is written to a single line of the file, and is in the following format:

<AIRFIELD>,<FACILITY>,<FREQ>

For example:

EDINBR,TWR,118.700

The airfield name can be up to 6 characters long. If a file is loaded with entries longer than 6 characters, the names will be truncated.

Issue AE

Frequencies are written in the usual manner; the MHz number should be between 118 and 137 MHz, whilst the kHz value should normally contain 3 digits, although trailing zeroes can be omitted.

14.1 USB Compatibility

Although intended as a generic USB interface, not all memory sticks will work in the TY96/TY97. A

Trig branded USB stick is supplied with each radio; the Trig USB stick will work correctly.

The Trig USB stick also has a read-only partition that contains a copy of this manual.

The USB socket is not intended for other functions, and is disabled during normal operation of the radio. It cannot be used as a charging point for other equipment.
