(SIDESLIP) ________________________________ Message 1 _____________________________________ Time: 04:06:53 PM PST US Subject: Zenith601-List: Radio/Comm issue! Grounding airplane from flying... HELP! From: "SIDESLIP" Hello all. Just purchased a Homebuilt Zodiac 601XL-B. Rotax 912ULS powered. A200 Radio, Flightcom 403 intercom. Aero flash strobes. The radio is intermittently squealing and tower cannot understand my transmissions. Tried both engine running and not running. Intermittent either way. When it is working, I get 5/5. When it begins squealing, 0/0. Previous owner said he had the same issue with cheaper headsets. Radio worked great, then it didn't. I'm using David Clark 13.2s's. The previous owner has a portable wired in as well, telling me that he's had issues in the past. There is a falcon T/B gyro, Garmin transponder and aero flash strobes. When the strobes are on, the pop of the flash comes thru headsets. I'm really stuck! Bought this plane, and now can't fly it! The rest of the plane is great,, ending runs PERFECT..... But this radio issue has me beat! HELLLP!

Grounding airplane from flying... HELP! Hi Chad, I'm going to guess you have a mediocre connection between the radio and either power or ground. This is easy to verify if there are any lights or other indicators on the radio. If the power is flaky and you key the radio the lights might dim or go out. Other than that I would suggest you remove the wiring harness from the radio and double check each connection. Wiggle the wires and see if they move. If you get desperate, rewire all the connectors. This will probably require some new pins and maybe new connectors. Good luck, Paul Camas, WA Zodiac XL just signed off, collecting hangar dust in the lousy weather.

Grounding airplane from flying... HELP! From: "SIDESLIP" Paul; There is also a handheld wired into the PTT/COMM, but it has its own antenna. Wonder if that's causing an issue? There are two switches on panel for send/receive for the handheld. Wonder if noise is entering there??

Grounding airplane from flying... HELP! Make sure that EVERY different piece of electronics has it's own single and INDEPENDENT ground wire. shared ground wires can lead to bad crosstalk an d problems like you are having. That should help significantly. Timothy A.
