Update Audio Noise
I found the culprit on my headset noise after installing my 796.
I have a music input jack, 1/8" little guy mounted on the gear tower since day one. This jack is not isolated from the tower. As noted before, I wired the 796 audio to the back side of this jack, in parallel with the rest of the audio inputs for music. I never had any noise until installing the 796. I have had to replace this jack a couple of times. Its not a very robust jack for the amount of use it gets. So after figuring out this was the culprit (unscrewed it while flying along and pushed it out of its mount, ignition noise went away immediately), I removed it and replaced with a 1/4" jack with isolators. This has cured my problem. Plus the 1/4" jack with a 90 deg adapter is a much more robust jack and should last a lot longer. |
I absolutely love the 796. I have mine mounted in my LSA and would love to add one into the panel of the RV-12 I am building. I fly all the time around Denver and get the you are in Class B warning popping up sometimes. I can be as much as 1000 feet below it and still get the warning. It has a strange anomaly on lateral limits too where it will occasionally warn when there isn't even a class B shelf above me. This happened with my old 496 and the 796. It is most prevalent closer to the mountains for some reason. I had a remote antenna for the 496 and have one for the 796 as well. It is a minor issue overal though. I am always talking to Denver and usually cleared into the Bravo anyway.
I also had some issue with the unit randomly restarting if you zoomed around too much too quickly but they seem to have fixed that with a firmware update. The other issue I have seen is not great support for Mac's when it comes to updating charts. I find that if I don't update all the states but rather choose the coverage area the charts that get downloaded end up corrupt using the Mac. I have to run VMWare to get around this. Again it is a pain but the unit makes it well worth it. I have flown several longer cross countries with the 796 and it is just incredible. The terrain feature is really nice, especially out here where the terrain can be a significant feature. The weather is outstanding as well. I am trying to make the decision on the GDL-39 right now. I have XM and renew in a couple weeks right before I leave for Sebring FL for the LSA expo. The only issue I have with it is the battery life. It would be nice to not have to have more wires running to the 12v plug. I know I can bare wire it in but that means another letter of authorization to make the mod. I prefer to see if it works first. Of course on top of the great visibility of the 796, the XM radio is a godsend on long cross countries too. Between the weather and radio, I just love it. |
