Sam,
It looks great!
Please check your private messages. I sent you one to get information to update
the Europa Club records.
Thanks

Assembled wisdom . . . .
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

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.
See Kunzleman combo head:

Can't speak on the shielding, but would think that changing to an LED strobe
would eliminate the noise (no high voltage spikes).
Cheers and good luck,
Pete
