Bill ----- Original Message ----- From: Ronald Cox To: aeroelectric-list@matronics.com Sent: Friday, October 05, 2007 9:19 PM 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.

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 ________________________________ Message 4 _____________________________________ Time: 01:01:25 PM PST US From: ECLarsen81@aol.com Subject: Re: AeroElectric-List: WTB Crystal Radio Dan, How far from Ann Arbor Michigan are you, I have a whole box.

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.

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. ________________________________ Message 7 _____________________________________ Time: 02:53:59 PM PST US From: Todd Heffley Subject: Re: AeroElectric-List: Wire 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. do not archive todd ________________________________ Message 8 _____________________________________ Time: 03:00:04 PM PST US From: Dan Billingsley Subject: Re: AeroElectric-List: WTB Crystal Radio Ed, I am located out of Mesa, AZ.

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. DO NOT ARCHIVE -------- Eric M.
