Certification Considerations
The SV-COM-T8 VHF COM Transceiver Module is supplied to Dynon Avionics by Trig Avionics
Limited and is derived from the Trig TY91 VHF radio system. The TY91 VHF radio unit supplied
by Trig communicates only with the TC90 Front Panel Controller. The Dynon SV-COM-T8
communicates only with the Dynon Avionics SV-COM-PANEL. Modifications to the TY91 to
create the SV-COM-T8 involved only control and interface – the transmitter/receiver sections
were not modified.
The TY91/TC90 is an ED-23C compliant class C (25 kHz offset carrier) and class E (8.33 kHz single
carrier) VHF radio. The TY91 has a nominal power output of 6 watts, and meets the power
output requirements for Class 4 and Class 6. The TY91/TC90 combination is certified to ETSO
2C169a 2C128a, TSO C169a and TSO C128a.
Note that the SV-COM-PANEL control panel is not certified. It is the installer’s responsibility to
determine the suitability of the SV-COM-X83 for use in the intended locale.
