I'm interested in what you used for filters too Pete.
...for my home made de-ice lights with super noisy power supplies.

Thanks for the clue, Pete!  Yes, all in one box, but I will re-visit the
wiring instructions for the LED lights to make sure what I did was kosher.

What filters did you use?

Thanks!

Gordon

I had similar issues with LED position lights that I had built myself.
Noise only on the lower frequencies.  It turned out the problem was on the
lines between the LED power supply and the LEDs.  Because of this adding
filters to the power supply lines to the lights did nothing.  I ended up
adding noise filters on the lines going to the LEDs and the problem went
away.  This was easy because mine was a home-made setup.  I'm guessing your
power supply and LEDs are all contained in one sealed package.

Hi Randy.

I have been tracking down a similar issue.  Thought I had it isolated to one
or both of my AFS EFIS'.  Installed a pair of capacitance filters at the
advice of Aerotronics... jury still out.

My reception issue was "like breaking squelch" but only happened on the low
end freqs - 118-121 or so, on both radios, each on separate antennae.  Very
consistent and repeatable.

I have Aeroleds for landing and both wing tip recognition lights...not the
strobes, just wing tip recognition lights.  Aerosun, I think the model is.

What freqs are you having issues on??

Very frustrating.

Joe , do you get any interference in your radios with these lights?
I installed similar lights a year ago and it causes reception issues at
times on some frequencies.  Curios if you experienced the same issue...
I would also be interested if anyone else has any suggestions on how to
resolve this..
Thx!
