Please check your private messages. I sent you one to get information to update the Europa Club records.

I have the standard dipole aerial for the radio in the closeout of the fin as per Europa instructions with the cable running down the Starboard side of the fuselage. The strobe is from Kuntzleman with the power supply fitted under the baggage bay and the cable to the fin running down the Port side of the fuselage. By necessity, the two cables are closer together in the fin and in the upper part of the fin would be running fairly parallel to each other. The Kuntzleman strobe wires are not shielded. The problem is a =93CHEW CHEW=94 noise in the headsets and by experimentation, I have proven the noise is coming in via the radio aerial. My question is . . . . What is the likelihood of success if I was to replace the unshielded wires to the strobe with a shielded cable? I realise moving the strobe to another location would likely be a solution but the fin is my preferred location if I can have it. Thanks in anticipation Kingsley in Oz ________________________________ Message 3 _____________________________________ Time: 04:54:13 PM PST US Subject: Europa-List: Re: Strobe noise in radio From: "rparigoris" Hi Kingsley The absolute worst thing you can do with Kunzleman strobe is to use shielded wire supply line! Twisted wire for supply works a lot better than straight wires. You can read about my resolution with single Kunzleman strobe power supply which was using two power supplies in the wing tips and twisted supply lines.
