Well I must have a good learning curve because I soldered both rear seat jacks in about half the time the front took me. I then checked the intercom and radio from the rear seat and it all checked out 4.0.
I am not logging the hours but I spent a lot of time trying to track down why the AP74 drops off line when I was transmitting on radio #2. I by switching the antenna cables between the radios I discovered that it has something to do with the left antenna. The autopilot servo wires run near there so to confirm the interference was there I removed the servo wires from the DSAB network and sure enough no issues with the AP74. But then this is so hit an miss, I figured I will wait till I put it on the gear and push the plane outside, I thought maybe the garage was the cause.
Well fast forward to 10:30 pm tonight. I went down to play with some ideas, I thought I would try to isolate where it was interfering. Well under the left side of the front seat the roll and pitch wires come to a terminal block and the two tie there on one side and then the other side gives me a single run of 5 wires to behind the panel. Now I was starting to think about having to run shielded wire for the DSAB when I cut the ties loose from the wire and tried to move them as much as I could from the antenna base. I had overlapped s portion of the run forward with the other wires to create a service loop. When I pulled this overlap away I tried the radios again on several frequencies and no problems. I hope this last like I said it has been kind of hit and miss.
Now I have to find out what is making some of my LED lights flash when transmitting.
