Maybe timings are also important - if, for example, they build it too fast, it may affect the quality badly? As experienced farmers say "calving sheds should be those good to want live there yourself) Wish I can succeed in this business.

Yeah . . . as we write, I'm loading the truck to go put up lights on the poles over some calving pens. First time in 6mo that bucket truck, weather and people all came together on same day. The work site is 25 miles out of town out in the Gyp Hills . . . one of those jobs where you load up with everything you know you will need and as much stuff as you think you might need!

Thank you for your offer and I acceptjavascript:emoticon(':D') . And I'm happy to cover any expense on my behalf. Eyebeam Mini Specs are here: http://www.aveoengineering.com/eyebeam-mini/ Aveo EMI Filters: https://tinyurl.com/y3epopac Aveo suggested remedy: Attached They also suggested multiple loops around the ferrite cores. Haven't tried that yet. Original request to Aveo: Request: Technical help please. I have installed an EyeBeam mini in my composite airframe. The shielded, twisted pair power and ground wire cable parallel unshielded, untwisted wires to the cabin speaker for a distance of about 5' . At that point the cabin speaker pair becomes a twisted and shielded cable. The two cables parallel each other for an addittional 12'. The shield for the speaker is grounded at the audio panel and the shield for the EB is grounded at the ship's single point ground bus. The problem: When I key the microphone, the EB turns on. If I key it again, the EB begins flashing uncontrollably. It is unresponsive to the dimming control and the on/off switch. The only way to stop the flashing is to disconnect the EB from power. The EB works fine when connected to battery power independent of the ship's electrical system. Attempts at a solution: Thinking that the the magnetic field of the speaker magnet may causing the problem, the speaker was disconnected and the mic was keyed. The EB exhibited the same uncontrollable flashing upon keying the microphone. I recognize that the problem does not lie with the EB. But I'm hoping that your design engineers, knowing what the EB's vulnerabilities are, can look at this and determine how to remedy it.
