My RV-9A has a FlightTech ITC-402P intercom, and there are problems. Audio quality is good in Isolate mode, but in the ALL mode, there's lots of noise.
No, I have not debugged all the wiring to the copilot side, but the symptoms may indicate an internal problem.
The existing radio is a GTN650, hooked directly to the intercomm with 150 ohm resistors on the comm and nav signals, and with the G3X alerts coming through another resistor (they're not working yet). I thought it would be real cool to use a GTR200 as the intercomm, hooking up the GTN650 through one unswitched audio input with a simple toggle switch for, granted, limited but adequate audio panel functionality. I'm still looking for somebody else who appreciates this brilliant idea but have decided instead to take the hint and abandon the idea.
I really don't want to spend a bunch of money for an audio panel with lotsa features I don't need or want. Anybody got any good suggestions? Or does anybody have an SL-15 looking for a really good home?
thanks
Ed
