best anti-RF ignition wiring TYPE

best anti-RF ignition wiring TYPE

background:
I am getting my vintage AM/FM Delco reconditioned with the intent of
getting that "cruis'n feeling" I will also add non-vintage sound
deadening, and other electrical/static improvements noted here and
elsewhere. Thanks for the help.

My query in a different area. In the sixties, I was always changing
ignition cables attempting to minimize "ignition buzz" on my radio.
(not really a problem since the mid-70s). Back then, I found one type
that worked ok, but I cannot find it any more. (Most of this help in
the 60's came from that Hams, thus I am including them in this
question)

Now for the "new" question.
What "TYPE" of ignition wiring for maximum should I get for my Avanti
(with modern electronic distributor) R2?

It's copper core spark plug wires that contribute to a lot of that hum,
isn't it? I bte that some of the hum in electronics from that era is
often attributed to the condition of solid state electronics not being
able to reject noise as well as they do now. What sort of mods are you
doing to the radio? I've had good luck in getting rid of hums in solid
state equipment from the 70's by using updated transistors, new caps
and all new sheilded wiring where appropriate. It worked wonders on the
Dynaco ST 120 that I rebuilt. Of course it's not for a car, but even
something as minor as touching up the solder joints with fresh, high
qaulity solder can make a world of difference. Check capacitors for
leaks as well.

Most all new cars use anti-rf plugs and cables.. Just get a set of
quality resistor plugs and resistor wires.

There are only 2 types of RF supression wire: resistive and inductive.
The latter is often referred to as "magnetic" and is widely available,
but it doesn't seem to work any better than the resistive type. A
significant amount of igniton noise comes from the connection between
the plug and the plug wire, and grounded metal shields over the boots
can help here. There are wire kits with these boots, mostly for German
cars, or they can be made with metal tubing slipped snugly over the
metal bases of the plugs.

Are you sure, first of all, that it's ignition noise you're experiencing, and
not alternator whine, or EMI from another source? Or is this just all
precautionary?

First thing I'd recommend, IF there's noise, is confirming the source of it,
before putting the time and effort into addressing one possible source.

Yep...as Matt says.........

I've got a so, so AM-FM radio with "inexpensive" plug wires.

The ignition is quite...but the alternator whines a bit. I know for a
fact it's the alternator because it's one of the one wire types that
comes in at about 1600 rpm when cold. So a first start at low
rpm...no chargeing....the radio is noise free. As soon as the
alternator comes in....whiiinnne.....

Just to clarify, he's talking about an Avanti here; having an
all-fiberglass body, suppressing ANY source of noise is of utmost
importance.

And it could be noise from a DC motor (fans for air/radiator). It could come a
variety of sources. I would narrow it down, and it shouldn't be too
hard to do either....

Generally, to cut down the static noise (RFI) on older cars, you would
find condensers on the alternator, distributor, wiper motor, and on
the radio itself. There was also ignition shielding and resistor wires
and plugs. The values on the condensers are all different, so swapping
them may cause problems rather than being a remedy. I've never seen any
on a heater or A/C fan motor, but it's also a source of RFI. Even
sliding your butt on the seat covers will create a charge. You remember
those little flexible tails that used to be attached to the chassis and
drag on the ground?.

Why even worry? My '64 R-2 was so noisy that I couldn't hear the FM
anyhow<G>.

I recommend getting a copy of the ARRL Hints and Kinks for Radio Amateurs
book... get one of the mid-fifties editions and there is a whole section
on eliminating ignition noise with homebrew shielding over the plug wires
and shield cans over the distributor.

I agree that with modern resistive wires, things will be a lot better. Back
in the fifties, plug wires were normally copper. Often folks would buy it
on long rolls and terminate it in the shop themselves. Today, plug wires
have a conductive element that is conductive plastic, usually a nylon with
carbon in it, and the wire itself has a few kilohms of resistance. That,
combined with a modern coil design, means you get less high frequency ringing
after the initial spark impulse which cuts way down on the noise.

I did not realize it was an Avanti. In that case, I think I would be
worried less about noise issues than making sure the radio antenna had
a proper centerpoise, because it can't use the metal body. The more
_signal_ you get, the more noise you can live with.

Check www.magnecor.com for EMI-reducing spark plug wires.

[Brooksie]

That's the same outfit that told me they could supply 7mm wires but only if
I wasn't putting the stainless shielding back in place.

They also sold spark plugs with built in resistors.
