Thanks, Rick Smile

Advantage of that one looks to be weight. Here are the light bars I'm trying out from AMZN:

Thanks, Joe Smile

Good to hear from you again!

Hey!

I have a Sonex flying...er in the hangar now I hope...and want to put LED lights in it. I've seen some nav/pos/strobe lights from Aveo

I'm disappointed to report that I couldn't solder the coax to the adapter fitting. I got the core soldered okay, but the braid stumped me. Solder would stick to the braid, but not the fitting. Think i ...

Thanks, Bob Smile

I bought one of those $20 ones off ebay yesterday. If I get antsy, get my xpdr installed and want it tested for mode C before it arrives in the mail, I'll cut down my homebuilt ante ...

Well, that cheap TED xpdr antenna is backordered. I came up with a few different lengths, googling. The diagram below shows it's ~2.5" from the ground plane (aluminum skin). Also read on the sequ ...

Hey

I rolled my own comm antenna a couple years ago. Antenna worked okay, but the location caused RFI, so I bought one and mounted it in a different location. This homemade com antenna could be ...

Ah!!

A picture is worth a thousand words. I'm guessing I won't need that barrel adapter, but I'll find out when I put things together.

Hi!

I'm installing a transponder in my Sonex. A couple years ago, I bought a 9-30-10 TED 90 degree coax adapter fitting, shown in the attached pic. What are the C ring and small cylindrical shaped ...

My SWR's all came in less than 2.1, thank Gawd! But wait, there's more. Here's what I posted on the MGL forum:

While trying to sort out my ignition noise issues, I had some odd things happen with m ...

you have a large, well connected ground cable Yes

. If there is a problem with both Transmit and receive then look to the
Antenna and Feedline or the radio itself. Seems reasonable. A hangar nei ...

I'm having a major problem with RFI in my Jabiru 3300 Sonex. Radio is MGL V6, just out a few months ago. Antenna is a belly mounted homemade one made from a CB antenna. It's 22" long with a singl ...

Sounds like most of the Jabiru ignition noise comes from the HT lead between the coil and distrubutor. Folks have replaced that with a shielded one and also put a couple ferrite bead clamps on each of ...

Thanks, Charlie.

The mags are from Jabiru, but I'm not sure where they get them. I'l find out more about the plug wires and exact type of NGK plugs these are.

Does the higher resistance of the ...

Ignition noise problem updated

Problem

I hear that distinctive spark plug interference noise when I listen to the radio. As expected, it varies with RPM. When I turn off the left magneto, 95% of ...

Yes, thanks for pointing this out. Sounds like I could disconnect the P lead of the left mag and see if it still makes noise. If it does, then Bob says it's getting out through the P lead wiring. If t ...

There are no filters on either mag. The filter capacitor is on the alternator. You think putting a filter capacitor on the offending mag wire might work?

My test pilot flew my plane for the first time today. Yeah! But now I have to fix all the problems that we've ignored. First on the list is the RFI issue. I have a Jabiru 3300 in my Sonex. Wired it mo ...

Making the bent antenna means getting another CB antenna, cutting it to length, heating and bending it. That takes easily less than an hour, even for me.

By far the longest part of the process was ...

Hi!

Thought I'd post a followup from a few months ago when I was making my com antenna. See http://forums.matronics.com/viewtopic.php?t=85809 In short, it's a RadioShack CB antenna that I cut short ...
