Home -> RV-7 and RV-7A topic: Strobe Noise Report

Author: Phil Birkelbach <phil@...> Time: Fri Jul 29, 2005 9:32 pm PDT Link

I installed a Nova Xpak 904 strobe power supply in my RV-7. When I did
it there were questions about it causing noise in the intercom / radios,
and I promised to report when I knew more. I am happy to report that I
powered them up tonight with the com radio on and while listening to
some Eagles on the CD player. I couldn't hear a thing from the strobes.
I turned the volume up and down on everything and couldn't get so much
as a tic out of it.

I installed the power supply right behind the baggage compartment
bulkhead, I used 3-conductor 18AWG sheilded for the strobe wires and
grounded the shields only at the power supply. The ground for the power
supply goes all the way back to the firewall and is grounded with the
rest of the stuff.

Just wanted to include this data point on the lists.

Godspeed,
