Well, to further clarify this problem. I seem to be able to hear ok on the
ground while taxiing around the airport, but after I leave the airport the
reception gets really bad. At first I thought it was a problem with the
approach frequency because that is where it would first start up. It was a
loud hiss in the headphones so loud that I could not hear ATC. In fact, I
have made two NORDO landings as a result on this loud hiss. I sent my radio
back to have it checked out and nothing was found. All this trouble is at
below 5000 ft and fine weather. I am flying off my 40 hours (22 so far) and
am only flying in good weather. These radio problems at a Class C airport
have made me afraid to fly. ATC could take some action against me if it
continues.
Lancair has an all carbon Legacy available but this one is all fiberglass
with the exception of the horizontal stabilizer, which is carbon. The
antenna is inside the fuselage about 4+feet forward of the stabilizer.
The bottom and rear half of the plane is in primer. The rest of the plane
is bare fiberglass. The primer ends just about at the location of the
antenna on the fuselage. I don't know if this would have an effect on the
static on the plane or not. I would have had to consider static wicks a
long time earlier in the build in order to install bonding wire. It is too
late now AFAIK.

He didn't mention flying in precip and static
wicks don't have anything to 'connect' to on
a glass airplane. If it's a carbon fiber then
wicks might be useful but my impression was that
his poor signal reports were at low altitudes
and probably slowed down for approach to landing
and in clear weather. P-static wouldn't hurt
a transmitted signal, only a received signal and
he didn't mention not being able to hear . . .
only be heard.
This is why the differentiation between weak-signal
static versus poor connection static is important.
The presence of carbon would support the notion of
it being the weak-signal variety.

Bill,
Could this be interference from
1. Your EFIS?
2. Your electronic ignition at higher RPM?
I have an SL-30 with the antenna behind my rear seat bulkhead, and a SL-40
with the antenna a homemade in the vertical stab.
SL-30 is noisy like you describe, but the -40 works fine.
I think it is the EFIS (was worse with Blue mountain, still present with
Grand Rapids, but not as bad)

Any chance that the kit has carbon material layered into the fiberglass for
some reason like rigidity, or some other form of strength needed..? Sure
sounds like the antenna is being blocked. Have you tried to temporary
substitute a simple outside antenna..? At least that would eliminate the
radio system as being the cause....

| Subject: | Burnt wire at Ducati Regulator |
I had originally posted this message on the Kitfox Forum and have since spoken
to Bob on the phone and he suggested that I put this on the aero electrical forum
as well. I believe that it was a bad connection done by the previous builder
and have since replaced/repaired with a new connector and a proper crimp. --------------------------------------------------------------------------------
I had a forced landing today due to smoke in the cockpit. Fortunately I was nearby
the airport and landed safely after shutting down all the electrical. After
removing the foam donuts that my butt cut out of the seat pads, I started troubleshooting.
I found that one of the wires from the coils/alternator where it
goes into the regulator was fried.

| Subject: | RG 58 Connectors VS RG 400 Connectors |
I currently have RG 58 coax connecting my radio to the antenna. Picking up a lot
of engine noise though. Would like to switch over to RG 400. But I see that
RG 400 coax has BNC 400 connectors. Will the BNC 400 female connector fit
on to a BNC 58 male connector?

Thanks for the follow-up Jerry and the pictures. It would be interesting
to have the old cut-off terminal to examine. It MIGHT have been a failure
of the fast-on terminal's grip on the tab but from your description of
the crimps, failure at the wire-to-terminal connection seems more likely.
In any case, peering at it under the microscope would still be an
interesting exercise.
As we discussed on the phone, if the new crimp tool you've purchased
specifically covers "PIDG" terminals, then you're good to go with
an inspection and perhaps some replacement of existing terminals.

It is doubtful that a change of coax will fix
any noise problem.
But I see that RG 400 coax has BNC 400 connectors. Will the BNC 400 female
connector fit on to a BNC 58 male connector?
Yes, "BNC" is the designation for a series
of connectors that will mate with each other
irrespective of the style of coax in the
connector.

Hi Bob
-
Though-this is not aircraft related,-you did mention-you were going t
o install an HID light system in-your vehicle.- I just installed an aft
ermarket system in a 2001 VW Passat.- No noticable noise/issues on the au
dio system, although I haven;t held my handheld nav/com near the ballasts.
-
Bottom line, for about $100 Cnd, the lights are great compared to the halog
ens I had previously.

Rick, Thanks for the input. I've not received the
exemplar kit that folks are reporting as 'noisy' but
I did get this kit from an advertiser on eBay.
http://www.ebay.com/itm/120843597694?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
The parts look good. My Sedona is in the transmission
shop so I won't be able to try the new lights until
Monday. Will let the group know what I discover as
well. Let me know if your hand-held 'sniffer' smells
anything.
