The lights from J.C. Whitney use about .5 amps and their output is MUCH better than the old halogen ones. Every thing is great until I try to transmit and then there is a huge amount of interference. Any suggestions?

Run the power leads through a torroid, and put a capacitor on both ends between the power lines. Maybe just installing a capacitor of 100n over the power lines as close as possible to the strobe power supply is already enough. If not, add the torroids and more capacitors. Ground the radio and the strobe power supply preferably at the same spot. Use twisted pair power supply's. Do not power anything else from the same leads (like nav lights). Also, disconnect the antenna to find out if the receiver still picks up the noise. If so, the noise comes in via the radio power supply. Use the same filter (torroid plus capacitors) in the radio power leads to remedy it. If using shielded cable, always shield at one end, and leave the other end unattached. Preferably use the Europa suggested COM antenna. This one has the best noise rejection potential. Make sure your coaxial antenna cable is properly RF-separated. You might need to coil it up close to the antenna, or use a dozen or so torroids over the cable (like proposed for the Europa antenna, but this applies to all brands). -- Frans Veldman ________________________________ Message 6 _____________________________________ Time: 03:26:58 AM PST US From: Frans Veldman Subject: Re: Europa-List: LED LANDING LIGHTS craig bastin wrote: > are you sure your lights are LED, in theory LED should offer nil EM > interference. Maybe HID??? LED's use a much lower voltage than 12 volts. If I were to build a powerfull LED system, I would use a switching power supply to avoid converting to much voltage into heat. Switching power supplies are notorious for their ability to generate EM interference. -- Frans Veldman ________________________________ Message 7 _____________________________________ Time: 08:18:20 AM PST US From: John & Paddy Wigney Subject: Europa-List: Re: Anyone have info how they mounted wing tip strobe power supplies? Dear Europaphiles, I know that this may be a little late for those of you who have already bought their strobe power units, but my installation works well without any interference. I have Whelen equipment and I mounted an HTS power supply at each wing tip. They are mounted on removable panels on the bottom surface. There is a weight penalty of about 1 pound compared to a single HDA power supply in the fuselage but all the high voltage cables are short and at the tip. No problems.

I modified a circuit for flashing lighthouse to get the desired pulses and duration basically its a 555 timer running a decade step counter to give you ten possible "ON" positions for the strobes then tapped off that on say pin 1 and 3 which gives you a nice quick double pulse and and about 4 seconds off time. this can be adjusted by the resistor on the 555 timer. This the drives the LED strobe head which consists of a 3x3 array of 280,000 mcd leds which makes it about the same size as typical strobe, but you could make it any shape you want just by moving the LED's around. The LED's are running on 12v but they are set up in series. Its took a little bit of fiddling but after 2 test runs I got the resistance correct and they ran for 2 months on a car battery before the battery went flat. As for brightness, I would say they are equally as bright as a comercial strobe unit. given the slight overdiving of the leds they should be around 3000 candle power per pulse. they are easily visible in full sun enough to not be desirable to look at. craig -----Original Message----- From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com]On Behalf Of Rick Sivier Sent: Friday, 20 February 2009 2:25 AM Subject: RE: Europa-List: LED LANDING LIGHTS I'm sure that I saw something in a magazine a little while ago about LED strobes.

It has been through a few hands but I have finished with it and am making it available to anyone who need to use it. Contact me and I will send it to the first asker. Thanks, Rob. Bill McClellan A164 Id like to think that I am not the only builder to have found a way to permanently bond the tailplanes to the torque tubes. After struggling to forcibly remove the tailplanes (which required both a large pry bar and sufficient heat) after my first attempt at following the factorys procedure, I decided that there is a much safer way to do the job. Substitute a mandrel for the torque tube and do the work on the work bench instead on the airplane. The attached drawings show how I did this. The epoxy still bonded the tailplane to the mandrel, even with plenty of wheel bearing grease on the mandrel and frequent rotation of the mandrel while the epoxy cured, but now I had a means to apply force against the rib via a screw into the outer mandrel section and a closed end tube against the rib (not shown in the drawings). In addition to using the mandrel instead of the torque tube I fabricated an aluminum retainer rather than rely on the fiberglass-epoxy layup alone to retain TP06, but this is probably unnecessary. For anyone who wants to use this method I will provide my (no longer needed) mandrel assembly at no cost just pay the shipping charges.
