Since I did not want to bother the list members with any more of my  pain & suffering, I stopped my daily updates. After wasting a month  with filters, capacitors, rewiring parts of the airplane, ripping out  and replacing the strobe / nav-light wiring with the best (most  expensive) wires etc, the net gain was 80% reduction of noise. But I  can still hear some noise from about everything that can possibly  make noise.
Sooo, I ripped out my radio and RST AP. Ordered a new ICOM A-200  radio from Steinair.com and new intercom FlightCom from Spruce. Wired  them in 2 days and I could not believe my ears. 100% silence and  beautiful audio quality. Tried turning on everything in the plane one  by one. Not a sound except what I'm supposed to hear. My wife said "I  have never been in an airplane with such a good reception".
Today I asked friend of mine, a HAM radio freak to come and test my winglet installed Bob Archer antenna's with his SWR equipment. He  came with the "Big Guns". After all, he wrote down bunch of numbers  and said that the antenna's are "excellent": One is 1:1.3 and the  other is 1:1.2. I read in the Icom instructions 1:3 is exceptable and  1:1 is perfect (I think?)
The bottom line the radio and the AP I had were not filtered by the manufacturer. So there goes another month down the tubes. I count it  as learning experience?
Thank you to all the builders that tried and offered to help with  their advise and knowledge. When I build my next plane I'll know  better :) Not a chance!
