    Subject: HID light noise
    Hi Bob, I've got a set of 50w HID lights that are extremely noisy. There is so much static on either the SL 30 or the 480 that they are practically useless. I don't dare turn them on in a high traffic area because of the poor radio reception I get when they are on. A hand held VHF radio also picks up the static and the amount of static varies with the distance from the lights. The vendor is Plane Lights and they said they would take them back if I can't solve the problem. I tried their solution of running a ground directly to the battery and that didn't help at all. Is this a winnable battle worth the trouble or should I just send them back? Is there anything simple that can be done? Thanks! Sheldon Olesen

    Are they DS1 style? Those are supposed to be less noisy. That's how I ended up with Duckworks.

    I have the same problem with Plane Light HIDs. Love the lights, hate the noise. My SL-30 is unusable with the lights on. I've tried all the simple fixes including making a filter per someone's instructions (I forget who but it was on this list). The filter consisted of a choke and capacitor. I followed the instructions explicitly but the filter didn't have any effect on the noise. I think I'm asking alot since the comm antenna on the radio that's affected is a Bob Archer in the wingtip right next to the light. The other comm is has a belly-mounted antenna that isn't affected at all.

    Don't know. They fit in the MR16 wingtip kit for halogen lamps that Van's sells. They look like this: As far as I can tell, there's nothing "less noisy" about them! I'm lucky in that they only affect my Comm2 so it's not that big a deal but for someone with a single comm they'd be a showstopper.

    I've Bob Archer nav antennas in each wing tip. With the ballast so close to the antennas is there any hope a different HID system? With my wings paint ed I don't want to be cutting holes in the leading edge. I'm doing the annu al and the weather is crappy so now is a good time to be dealing with the pr oblem.

    Subject: Re: ectric-List:
    Hello Paul The GPS gives groundspeed, track, and position. You can go into a lookup table to find the magnetic variation at your position. If you know the TAS because you have pitot static info and temperature, you should be able to solve for the wind vector I believe. Same as can be done with an E6B computer. I think it goes heading vector plus wind vector equals track vector. So if you know any two vectors you can compute the third vector. Mostly I was just pointing out that many glass PFD/ADI systems already have all the sensor info they need to display a magnetic heading if the designer wishes to display it. I often fly an aircraft that does just that. It has no magnetic sensors but it computes and displays magnetic heading. Of course variation does change slightly over a multi year period so minor changes in the lookup table might be appropriate every few years if high accuracy is desired.

    No, you're missing the heading. Your lookup table is just giving you the magnetic adjustment to a 'true' track. Most GPS's do just that when you tell them you want a magnetic track. You said your aircraft has no access to magnetic information. Without that it can't tell your plane is pointing in a direction other than the ground track - magnetic or not. Your heading will only match your track in no wind conditions. You still need something to tell you which way the plane is pointing, not tracking. However if the EFIS has access to magnetic heading data, then you can calculate wind speed and direction in the EFIS.

    I tried copying your setup exactly, from your post to this list back in February. I was pretty excited since your symptoms seemed identical to mine, even the Dynon dropping offline. But, no luck... What antenna are you using, and where is it? I have an Archer antenna in each wingtip, one nav and one comm.

    I have an archer Nav in the left wingtip and use it with a 430w. The hid lights have no effect on them with my filters installed. Keep in mind that these ballast for these cheap HID lights are not all created equal or the same. I may have just gotten lucky with the ones I need up with.

    Subject: Falcon amp/volt gauge hookup
    From: "bnelson79" <bnelson79@embarqmail.com>
    Ive just gotten a combo Falcon amp/volt gauge. It has four connections on the back. Two connect to either side of the shunt. The third to ground. But the fourth is supposed to connect to the ignition switch. But I have an ACS rotary switch with multiple connections. The gauges are not reading though and I assume it's because this fourth connection is not right. Does anyone know how this last wire should be attached to the ignition switch?

    Bill, << Falcon amp/volt gauge. .. four connections .. But the fourth is supposed to connect to the ignition switch. .. how this last wire should be attached to the ignition switch? >> Believe it goes to the BAT terminal which is at about 11 o'clock viewed from the back on the ACS switch. You will need to crimp the proper sized ring terminal onto the wire. The BAT terminal is the source of power for the starter solenoid. Tom Kuffel
