Adding this from last weekend. Got everything back in, with ferrite beads installed on everything going into and out of the EFIS and the GNS430w. There’s definitely a big difference in both the amount of noise generated by the EFIS and the amount of RF dumped into the EFIS on transmit, even in a shop full of metal things. I still have to wire in the RDAC and sensors permanently, but this time around, I actually got the EFIS audio output wired in correctly, and I can now hear Bitching Betty in my headset. The volume is a little low, and the sample rate is terrible. I’m not sure what to do about that. Maybe Matt at MGLUSA can shed some light on it.
I also mounted an avionics ground plate full of tabs right near the radio stack for shorter connections between avionics and ground. It also looks like my antenna will go under the pax floor pan to keep it as far away from the antennas, sensors, and servo in the tail or the radio stack and EFIS.
I also get to fish out the cheesy RCA cable from the main bundle and replace it with a twisted triple to carry power, ground and data to the AHRS and magnetometer. If I can get all this shite to sing in harmony, then it’s on to the baffles and other FWF fun.
The system won’t be noise-free until I no longer have unterminated wires, which means at the airport with the wings attached and all circuits complete, but I can live with that for now.
