The NEW Trig TT31 Mode S transponder has been designed to meet the European elementary surveillance requirements, as well as fitting the same mounting tray as the popular KT76A/C transponder, making it ideal for new or retrofit installations. The TT31 has a backlit graphic display, rotary knob for setting squawk code and flight ID, and easily operated functions.
The TT31 transponder is an ED-73B Class 1 compliant Mode S level 2 datalink transponder, with support for extended squitter. It meets all the requirements for non-diversity Mode S elementary surveillance transponders in Europe for both IFR and VFR flight. The TT31 also supports 1090 MHz Automatic Dependent Surveillance Broadcast (ADS-B) extended squitter. By linking the TT31 to your existing GPS receiver, the TT31 can transmit position information to appropriately equipped ground stations and other aircraft. The TT31 will also be field upgradeable to support Traffic Information Service (TIS) functions, where available, by interfacing to an appropriate cockpit display.
The TT31 is designed to be compatible with 14 and 28 volt systems without special configuration, and is compatible with serial and parallel altitude encoders.

I just want to thank you all again, and especially you Anne for your help in tracking the package.
It is wonderful to work with people like you, for whom it is of no consequence whether one buys a simple cable or an expensive GPS. Your effort is the same in all cases.
Keep up this way of doing business, it is refreshing.
May I reiterate my thanks to you for your friendly and very prompt attention to my order.
