That's a great idea- you could also cut away the little circular bits on the
side and gang the fuses in a row...

Not all holders have that much free plastic and you'll
want to sand away the proposed mounting meat to make
sure no fuse wiring extends into the boss.
I considered just bonding this holder to the bracket but
wasn't sure about storage temperature extremes. Decided
to bond it to fixture and then re-enforce the bond
with screws.

Subject: AeroElectric-List: Intermittent no radio reception
I had a problem with my radio reception today and I am not certain where to
look for the cause. I was flying and the radio was working fine. I was
listening to Approach while I flew around and I could hear them fine. I
decide to land, so I dialed in ATIS. I didn't get anything. I noticed that
I didn't have the "RX" showing on the radio. At the time I was about 25
miles away and 2K feet. I thought maybe I was too low and far away,
although I had been listening to Approach when I dialed in ATIS. As I got
closer, I climbed a little and suddenly I could hear them so I didn't think
much more about it. But I am pretty sure that I should have been able to
hear them because I could almost see the airport from where I was.
After I contacted approach and was handed off to Sanford tower, I didn't
hear from the tower for several minutes, then they asked me "how do you
hear?". I replied "Fine". I didn't think much more about that incident
either, but after I got home, I listened to the tower archives and I found
that the tower had asked me 4 times how do you hear and I only heard the
last one.
This makes me feel that I have some kind of intermittent problem with
receive. Everything else was working on the radio that I know of. It seems
to be just an intermittent receive problem. Do you have any ideas where I
should look for something like that?
I have this type of antenna.
http://www.aircraftspruce.com/catalog/avpages/antennasystems.php
It does not have a ground plane as it is a half wave antenna. The one I
have it the 5T which allows the coax to come out and be supported on the
side of the fuselage with mounting brackets. The antenna is inside the
fuselage just behind the rear bulkhead on the Lancair Legacy. It is mostly
vertical, but the ends (top and bottom) curve following the shape of the
fuselage and become horizontal for the last 4-5 inches. I think the antenna
is something like 41-42 inches long. My plane is all fiberglass. The only
carbon fiber is in the horizontal stabilizer, leg fairings, and the wheel
pants. None of this carbon is closer than three feet or so to the antenna.
But what ever this is, it is intermittent. The receive and transmit seem to
work fine until they don't work at all. I have heard others tell me that my
transmissions were staticy from time to time, which is why I have been
trying to hear myself by listening to the recordings from ATC. If I had not
done that I would not even have known that I missed 3 radio calls from ATC.
I was probably close to 5-6 miles out and heading directly toward the
airport when I was missing the calls.
Also, unrelated, I noticed that if I am on autopilot, (TruTrak Digiflight II
GPSVG) that the autopilot goes haywire when the radio transmits. I have
heard of this problem on the internet but have not looked up what may be
causing it. Maybe you know off the top of your head??
Thanks for all you guys help!

No I don't know if the headset is the problem, but it is a Lightspeed Mach 1

Subject: | SSF-1 WIG WAG Flasher |
I built my RV using a B&C SSF-1 wig wag. Wired it per Aeroelectric
recommendations and it worked fine.
I changed one light to a Xenon lamp using a Philips Xen Drive XLD912
Standard power supply. This does not load the SSF-1 flasher as required
so my wig wag no longer works. I would like to keep the Xenon on one
side and the incandescent lamp on the other. I would be happy with
flashing one lamp if not both.
Any solutions?

This is way off the topic, but how do I find a live (in 2" plastic

off the power without calling the electric company (read $$$). I know the
general location, but need to drill some 4' deep holes for a pole building
and don't want the surprise of a short lifetime or have to splice cable.
What sort of gizmo can I construct? A short Google search shows cable

I'm not sure what you require here: why do you need to shut off the
power - surely the power company knows where their cables are if they
are competent - if they don't they should be ashamed, and only too
willing to find them at no cost

We have a system called "Dig Safe" which is a no charge service. They will
come and mark all of the buried utilities for you. Check that out.

Don't know where you're located, but here in Ontario (and in many other
Canadian provinces) it is a legal requirement to call "Ontario One Call" a
non-profit corporation before doing any kind of digging in the province.
They locate, telephone, cable, electric and gas lines free of charge before
any work which might damage underground utilities is done. Check with your
local municipality as they may have a similar service.

Subject: | Re: SSF-1 WIG WAG Flasher |
Dick,
If you truly would be satisfied with flashing one lamp and if you have enough
power budget for the additional current the Xenon lamp requires and if you don't
mind a little re-wiring, you could substitute a power resistor for the
incandescent lamp that was removed. The resistor will keep the flasher happy.
Think of it as a non-illuminating lamp :-)
Assuming you're using a 55W lamp at 14V, you would need 3.6 ohms capable of
dissipating 55 watts half of the time (50% duty cycle). A couple of 10-ohm,
20-watt resistors in parallel should be close enough to fool the flasher and if
not, add a third one. FYI, those resistors will get very hot; don't put then in
your lighting switch panel.
My wig-wag uses an electro-mechanical flasher too and this is what I plan to do
when I upgrade my lights unless I spring for a new (solid-state) flasher. But
that's not going to happen until after the airplane's flying <g>.

Subject: | Re: Finding a 220 volt buried line |
Don,
Having spent the biggest part of my career in digging, including a few
hundred buried "whatevers",
the first thing you are required to do is called your local free utility
locating service. They are ALWAYS listed
in the front of the phone book!
I'm sorry to admit, but the last one I found my 2"PVC conduit 200A
service to my shop, it was with my backhoe. Funny thing
about 2" PVC conduit, and service entrance cable...it rips out like you
never knew it was there!!
The locating service can give you a very close approximation of the
utilities location DIRECTLY below their detector.
They will NOT, however, tell you how deep the line is! (although I have
had a couple of guys cheat and tell me anyway).
The reason they aren't suppose to give you a depth is, let's say he says
it's 48". You fire up the Case 580, dig down to 46"
and snag it! Maybe where YOU dug it WAS 46" (obviously, it was, since
you just tore it out).
The point is, the locator does not want the responsibility of
everybody using any machine to dig down 98.45% of the way.
Generally, they don't mention any depths.
I have used my backhoe many, many times to expose water lines,
electric lines, etc. The trick is have a spotter watching the hole
like a hawk!! You absolutely have to dig INLINE with the service,
because there is a much less likely way of tearing it up,
compared to digging transversely.
The BEST way, and easiest and safest, is to have your locator guy mark
the service on the ground. Then paralleling his
paint line about 24" off to the side, (and assuming nothing else is
located--like gas or phone lines, etc), dig a really big hole. Really
big!! Dig your hole
big enough to drop a car down into it, and extra deep. Then, after you
have your big, deep pit "next" to the service, carefully
dig in the direction of your electric service......letting all the dirt
fall down into your extra deep pit. The dirt will easily cut away and
fall
your direction. This is a hellava lot better then having to excavate
all the dirt with a pick and shovel.
Digging down 4' and finding a buried line is never easy, but that last
suggestion is the best I've found.
In some areas, you have to be careful about getting into pits. Many
people have been hurt or killed because the walls collapsed.

receive. Everything else was working on the radio that I know of. It seems
to be just an intermittent receive problem. Do you have any ideas where I
should look for something like that?
I have this type of antenna.
http://www.aircraftspruce.com/catalog/avpages/antennasystems.php
It does not have a ground plane as it is a half wave antenna. The one I
have it the 5T which allows the coax to come out and be supported on the
side of the fuselage with mounting brackets. The antenna is inside the
fuselage just behind the rear bulkhead on the Lancair Legacy. It is mostly
vertical, but the ends (top and bottom) curve following the shape of the
fuselage and become horizontal for the last 4-5 inches. I think the antenna
is something like 41-42 inches long. My plane is all fiberglass. The only
carbon fiber is in the horizontal stabilizer, leg fairings, and the wheel
pants. None of this carbon is closer than three feet or so to the antenna.
But what ever this is, it is intermittent. The receive and transmit seem to
work fine until they don't work at all. I have heard others tell me that my
transmissions were staticy from time to time, which is why I have been
trying to hear myself by listening to the recordings from ATC. If I had not
done that I would not even have known that I missed 3 radio calls from ATC.
I was probably close to 5-6 miles out and heading directly toward the
airport when I was missing the calls.
Also, unrelated, I noticed that if I am on autopilot, (TruTrak Digiflight II
GPSVG) that the autopilot goes haywire when the radio transmits. I have
heard of this problem on the internet but have not looked up what may be
causing it. Maybe you know off the top of your head??
Thanks for all you guys help!

Subject: AeroElectric-List: Finding a 220 volt buried line
This is way off the topic, but how do I find a live (in 2" plastic
conduit) 220 volt cable buried 4' deep in the ground. I have no way of
shutting off the power without calling the electric company (read $$$).
I know the general location, but need to drill some 4' deep holes for a
pole building and don't want the surprise of a short lifetime or have to
splice cable. What sort of gizmo can I construct? A short Google
search shows cable locators for greater than $600 and rentals for $90
(fifty miles away).
My apologies, but the group is so good at not wasting $$$ or EMF!

Ed,
...good suggestion..as if that has never happened to all of us.
Especially when the plane comes out of some work at an avionics shop.

I had a problem with my radio reception today and I am not certain where
to
look for the cause. I was flying and the radio was working fine. I was
listening to Approach while I flew around and I could hear them fine. I
decide to land, so I dialed in ATIS. I didn't get anything. I noticed
that
I didn't have the "RX" showing on the radio. At the time I was about 25
miles away and 2K feet. I thought maybe I was too low and far away,
although I had been listening to Approach when I dialed in ATIS. As I
got
closer, I climbed a little and suddenly I could hear them so I didn't
think
much more about it. But I am pretty sure that I should have been able
to
hear them because I could almost see the airport from where I was.
After I contacted approach and was handed off to Sanford tower, I didn't
hear from the tower for several minutes, then they asked me "how do you
hear?". I replied "Fine". I didn't think much more about that incident
either, but after I got home, I listened to the tower archives and I
found
that the tower had asked me 4 times how do you hear and I only heard the
last one.

Try dialing 811 for "underground services alert" (USA) and the utility
should come out and locate the cable for you!

Dick,
If you truly would be satisfied with flashing one lamp and if you
have enough power budget for the additional current the Xenon lamp
requires and if you don't mind a little re-wiring, you could
substitute a power resistor for the incandescent lamp that was
removed. The resistor will keep the flasher happy. Think of it as a
non-illuminating lamp :-)
Assuming you're using a 55W lamp at 14V, you would need 3.6 ohms
capable of dissipating 55 watts half of the time (50% duty cycle). A
couple of 10-ohm, 20-watt resistors in parallel should be close
enough to fool the flasher and if not, add a third one. FYI, those
resistors will get very hot; don't put then in your lighting switch panel.
My wig-wag uses an electro-mechanical flasher too and this is what I
plan to do when I upgrade my lights unless I spring for a new
(solid-state) flasher. But that's not going to happen until after
the airplane's flying <g>.
If your new HID lamp/pwr-supply combo will tolerate
flashing, then you can also consider adding some dummy-load
resistance in parallel with the wires to the HID
power supply.
We did a patch to the B&C Wig-Wag instructions to
accommodate LED lamps, same fix should work with your
HID too.
