Ron,
Check http://strobeguy.safeshopper.com/32/1922.htm?248 and see if
this will do the trick. Give him a call first to make sure the wire
gauge is what you need.

Subject: AeroElectric-List: Source for Strobe Cable
Hi 'LectroFolks,
I'm looking for a source for multiconductor cable to be used for
installing Whelen strobes. I need the cable to go from the power supply
to the strobe units/heads, not the power lead.
The current "installation" kit I had (and used on another airplane)
uses a Belden cable consisting of 3 - 16ga. conductors with a shield,
insulated with (I think) some kind of rubber/vinyl. I don't think it's
teflon.
I would like to find some additional cable without buying another
seriously overpriced "installation kit" which includes connectors I
already have.
I probably need about 50 feet, but I'd buy more if it's
semi-reasonable, (up to 100').
Does anyone know where I can find this kind of cable? The 16 ga.
spec is probably seriously overdone, since the high amperage load is
extremely intermittent, but that's what Whelen uses, and this particular
installation is going into a certified Cessna. (I used the other cable
kit in my Glasair.)
I've looked at SteinAir, and they don't have anything in cable
bigger than 20 gage, and are really short on multi-conductor stuff.
Thanks,
Ron Cox
Glasair Super II F/T under construction at C77 near RFD

Great installation, thanks for sharing it. If others have builder sites with
similar documentation of electrical installations please share them with us.

Subject: | Transponder antenna in rag/tube aircraft |
I'm getting reports of very poor reception of my transponder in my Piper
Colt. I've been through chaper 13 of the conection and can't really find
anything that addresses this sort of airframe.
Questions: I assume I should use a ground plane of 5 1/2" diameter as
per a composite aircraft? Do I make sure the ground plane is isolated
from the metal frame or bond it to it? Does it matter how close the
ground plane is to the metal structure?
Any help gratefully received
Thanks
Peter

Dan,
How far from Ann Arbor Michigan are you, I have a whole box. I do travel to
Chicago about every weekend. somewhere in these vicinities would save the
shipping.

Subject: | Re: WTB Crystal Radio |
Ah, well do I remember my first Crystal radio back in 1950. Being
lacking in that stuff called Money back then as a 10 year old, I wrapped
enable coated wire around a Quakers Oatmeal box bring out a twist of
wire every 10-20 windings. The air of the box provided the capacitance
and of course the wire, the inductance, for my tuning circuit with the
twist poking out of the windings being scraped clean of its insulation.
A paper clip wired to the grounded end was used to tune the frequency by
clipping it on to the appropriate twist of wire. Lets say the bandwidth
was somewhat broad and hearing several stations at one time was not
unusually.
The crystal was also home made. I read someplace,probably Popular
Mechanics, that the crystal used in the those expensive commercial
crystal radio sets was lead sulfide. So I got some chunks of sulfur at
the drug store, found a lead fishing sinker or two and melted them down
in one of my mother's sewing thimbles. Then I dropped a chunk of sulfur
into the molten lead and when it cooled down, I had my lead sulfide
crystals. A piece of fine wire for the "cats whisker" and I had my
crystal radio. It actually worked.
However, later on they came out with geranium diode that cost about
$5.00 at the time. I saved up my pennies and purchased one and it made
a tremendous difference in easy of tuning - no more cat whisker hunting
for the "hot" spot on the lead filled thimble. I also incorporated a
real variable capacitor out of a radio I found discarded in the local
town junk yard. Interesting enough one of the stations, was far way in
Del Rio Texas, the station was apparently located just across the border
in Mexico where they apparently were not restricted power wise.
Thanks for bring back some great memories.
Ed

I'll try to get some pictures later tonight, but for everyone using
these fuse blocks...
You can get 90* 1/4" push-on fittings. I (fortunately) have a friend
with the expensive crimper, 'cause he uses bags of them in his
business. These are VERY nice to have when you're trying to fit the
fuse-block in a tight space like Eric is doing.

I have a Kingsley machine with 10 clockwheels, manual wirefeed.
Overly difficult to use for small projects.
I would be willing to sell it to a good home though....
My 2 cents.. Stick with Bob's simple labeling methods, build one end
of most cables on the bench, run plenty of length and do not do not
cut the far ends to length until the clamps and ties are tight.
Take extra care to route cables in sensable cable-runs....then reroute
them a week later because you figured out a better route.
I have done plenty of this work, and sensable wirerouting and
clampling goes a lot farther than stamped wires.
also, good, hand-drawn prints are more valuable than stamping.

Tons of stuff on the web. See:
http://sci-toys.com/scitoys/scitoys/radio/radio.html
WWI soldiers used two razor blades stuck into a thread spool with a cube of anthracite
coal as a rectifier. Of course all they had to do was read morse code
from giant spark transmitters.
I recommend making your own variable capacitors. There were many early and clever
designs before the D-shaped rotary thing.
In the 1920's and 30's Popular Mechanics published dozens of xtal sets.

Browse thru the previous entries for how I got to this point. On current
project fuse blocks are mounted on sub-panel behind glovebox, which has hinged
panel on rear wall that drops down to expose them. This actually looks like a
neater approach so far...
