I think I used a 10 uF ceramic cap across the leads going to each LED, pref=
erably installed where the wires come out of the LED power supply.  You sho=
uld also twist the pair of wires going from the LED constant current power =
supply and the individual LEDs.  If the capacitor proves ineffective, you m=
ight have to add a choke in-line on the wire.  A ferrite bead would also he=
lp, but it takes up lots of space.

Thanks for the clue, Pete!  Yes, all in one box, but I will re-visit the wi=
ring 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 fi=
lters to the power supply lines to the lights did nothing.  I ended up addi=
ng 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 on=
e 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.  Ver=
y 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 tim=
es on some frequencies.  Curios if you experienced the same issue...
I would also be interested if anyone else has any suggestions on how to res=
olve this..
Thx!
