Hi Richard
I have a Trig 21. Very straightforward to install and use.
The only criticism I have is that it doesn't remember the
alternative (non-7000) squawk after it has been turned off.
It also has the encoding altimeter inside it so a separate
one is not required (allowing sale of the old Mode C
transponder AND its encoding altimeter - on eBay in the
USA !!!!!)
Ideally as my airfield is in the Stansted TMZ I would have
0013 stored/saved in there, but I have to put it in as the
"flip-to" code each time I start up.
