Does Anyone Know What This Is?

[billybronco1]

Is this part of the radio, which I do have but its not mounted in the car (too big) Trying to clean up some wires, this is hooked to a hot wire, not pretty.

Looks like maybe an archaic resistor. Can you measure voltage between the input and the output wires? Let it heat-up with power on it for a few moments. DD

What ever it is, it arched before. Look at the burnt part of the red wire. You need to look into this soon.

[billybronco1]

I had to take the glove box out to follow the wire, it goes up into the right windshield post into the head liner. Can't imagine for what. Car has vacuum wipers, can't be for that. It does have a dome light that does not work, I doubt it is for that. I also found three other wires that go the same direction that appear to be for a speaker. Does anyone know where the speaker was mounted in these cars, I don't think it was in the radio.

Radio antenna lead with coil....

[jimTN]

Speaker was mounted in the header above the windshield. If it did not have a hot wire connected, it could be some sort of a antenna booster.

[billybronco1]

Okay speaker wire location solved. You bring up a good point on the radio antenna, where would that be mounted? Did they have mast type back then? I don't see where there might have been holes for one on the car.

The hot resister type thing is still a mystery, I disconnected it for now.

Antenna is the chicken wire in the roof....All closed cars were pre-wired from the factory. The lead located in the left cowl goes to the roof antenna with an attachment to the wire mesh in the top assembly.

[billybronco1]

Okay thanks, that answers that, now to solve the mystery part. Could it be something to do with the antenna? Some kind of 6 volt booster? Later I will open it up and see if it has any markings, there is no way I'm keeping this connected.

[alanwoodieman]

it is an antenna signal "booster"

[billybronco1]

Solved - thank you its being removed, I will save it though.

[rotorwrench]

It may have been attached as a way to match impedance on the antenna wire. Most of the antenna wire replacements I've seen for these don't include and impedance coil but you never know what they might have been trying to do with that. The EFV8 club has had a long running series about radio equipment used in the early fords this year and maybe part of last year. I'd have to go back and look at all that stuff to see if it mentions anything about a coil like that.

Do you know which radio make & model you have? There is info out there for the old Ford tube type radio sets.

As far as I'm aware, there is no way to "boost" a signal by applying DC power to the antenna. It just needs a mast or in this case a wire mesh to receive the signals. Impedance is important but putting any power back through the antenna lead might fry the input circuitry.

[billybronco1]

It had a Motorola 60 standard broadcast radio

[alanwoodieman]

rotowrench do you know what a load coil is?

[petehoovie]

An antenna loading coil is an inductor placed in series with an antenna element in order to lower the antenna’s resonant frequency.


I've never seen an external one used for medium wave band AM radio though -530 kHz to 1700 kHz ....

[billybronco1]

That does not show it hooked to 6 volts though

Maybe that's the reason your radio is not installed....

[billybronco1]

No, it was taken out because its too freaken big, I still have it.

[petehoovie]

You removed the radio because it was in your way? Did the radio work before you removed it?

If it is the antenna lead, I don't know why power was applied to it. Maybe, in its past, an amateur played with the radio.....

[meric42]

The other option is that it could be a series choke coil, connected in the power feed to the radio in an effort to reduce high frequency Ignition and/or Generator noise being passed through the power feed to the radio?

Either turn the radio off or throw it away. Tune-up that flathead engine and listen to that "beautiful music" while toolin' down the road! Simple, affordable and gratifying solution. DD

Not so fast; maybe he likes the crop reports and foreign language stations so common on AM radio these days. I even found one up here in Minnesota that plays Mexican music that sounds like "Old-Time" polka music to me. You know, trumpets and oomp-pa tubas and accordions. I got kinda used to it.

[Tim Ayers]

If in NYC area, we still some decent talk radio stations around on the AM dial. That's if you can stand the static.

Don't forget that there is a difference between a two way radio transceiver antenna and a plain old radio receiver antenna. All a regular car radio needs is an antenna that will receive signals of a frequency range depending on the receivers frequency band. An AM radio only needs a simple antenna and any coils will usually be inside the radio set.

A transceiver antenna can be a bit more complicated.

Ignition noise, generator noise, or what have you, can be filtered with a capacitor in the noisy items power line. The King Seeley senders sometimes had caps on them too.

The Motorola 60 was not a Ford standard option. The Motorola 60P was actually a police radio made from the model 60 and they are kind of big in either case. They were a reciever and they did have a load coil system. Here is a link with some info.

They mention a magic eliminode system for these. The eliminode system was supposed to be a noise eliminating dual antenna system with one antenna to eleminate noise and the other to pick up the radio frequencies. I don't think this system lasted very long. Here is a diagram link.

Car radios were still kind of a new thing in the mid 30s so a lot of different things were being experimented with. Those Motorola Model 60P receivers were likely among the first police band receivers put into wide use before Police bands got out of the AM frequencies and went to VHF.

Yep, that's mine in the web site model 60. This part is definitely is a radio component, its now out the car and in a storage box with the big heavy radio. Probably will never be used again.

During my first four years of a career with the FAA, I was in an engineering group that traveled extensively doing evaluations and mods on outlying navaids. As such, I spent an awful lot of that time in South Texas, down in the neighborhood of our southern border. 'Chalupa' music is just about all that could be found on a radio down that way, especially back in the '70s. Drove me bonkers, 'cuz it ALL sounds the same. DD

Certainly looks like some sort of inline noise suppression device i.e. what looks like a capacitor in the middle with a coil wound around the outside.

Maybe because its a Deluxe this was part of the deal.

The usual Philco and Zenith radio sets are more common but there were aftermarket sets targeted to all the domestic cars that were more popular. The Philco FT6 was the most common.
