James.
This is an old post to the list I found. This noise filter will work for your alt. noise also.
Mark S.
I did some looking at Radio Shacks web site and found
that they have discontinued the noise filter 270-051
with no replacement part.
I found the same part at Parts Express
(www.partsexpress.com) under the part number 265-042.
Worked great on my Val-Com radio.
Search the Aero Electric list for my name and you will
find all the info when I had my problem.

Here's the latest on my situation. I connected my radio directly to
the battery (power & ground) in the aft fuselage but still had the
same whine. I then took a motorcycle battery and connected the radio
directly to it and the whine was completely gone. The radio was
absolutely clear with the engine running. I have ordered an inline
noise filter suggested by several individuals and will let you know
how that turns out when it's installed. Thanks again to everyone who
responded. Jim

You most likely have a diode out in the alt......
A filter capacitor can't fix that....

I asked Jabiru about the diode suggestion today. They said the Jabiru system is a set of permanent magnets producing current to a regulator-rectifier and doesn't have a diode like a Continental or Lycoming so I guess that rules that out but thanks for replying. Jim

There are plenty of diodes (rectifiers) and other semiconductors inside the regulator that could be fried. AC still has to be turned into DC somewhere. See page 54 in the manual linked below for a schematic of the regulator. But since the regulator is encapsulated you would have to replace the whole unit.

Hmmm, will work on finding another rectifier to try. Thanks you. Jim

No more noise! I purchased a inline noise filter from
davidnavone.com. Here is the link (scroll down to N-700 filter):
http://www.davidnavone.com/cart.asp?24&cat
The filter cost $15, It is the N-700 electronic noise suppression
filter which uses solid state active filter elements as well as a
huge passive torodial choke to eliminate inline noise. It is
approximately 6" long and 1.75" inches in diameter. It weighs 8oz.
There are 3 wires; the green goes to existing power from your radio
fuse (or buss), the red to the power lead from your radio and the
black to ground.
Another note: The main consensus is the regulator/rectifier has a
bad diode. Jabiru USA is sending another R/R for me to try. I
really appreciate their help. I would prefer to find the original
source of the noise instead of masking it so will try that when it
arrives. Jim

Jim,
i am buying the noise suppressor, N700 from DNavone. How is yours working out, any suggestions?
