Intercom function
This function is very good on both the trig and Becker, the gliding fraternity favour the Becker because of the lower standby power consumption. This of course is not a consideration if you have a generator on your aircraft.
I have been most impressed by Trig, I have three of their transponders all have a 100 % servisability record.
If you need an intercom I have just removed a PS Engineering intercom from my aircraft due to an Avionic upgrade, this to has been faultless and would not be getting removed if I did not need the functions of an audio panel....... the intercom could be yours for a small consideration !
