The message below should explain it all. If you have such a car you would like to sell please PM me. (Yes, I'll put it the wanted ads also)
"Hello, My name is Jeffrey Lemaux I am the curator of the Detroit Police
Museum. I don't know if you can help. I am looking to purchase a 1919-1921
model T touring car to install a reproduction of the first radio car
antenna. The car will be displayed in the lobby of the Detroit Public
Safety Building near the entrance to the museum. I am not looking for a
show car or one restored but a $5,000 to $8,000 car in decent shape.
Detroit was the first Department in the country to make a one way police
Walter Stick with a one-way police radio, 1922. The first one-way police radios were used as experiments by Detroit police and installed in the back seat of a Model T Ford police patrol car.
And when they weren't using the radio they could hang out their laundry.
I'll bet back then the radio took up all of the back seat
Jerry, Detroit is hurting badly, but I'd like to see them get their car. I'll donate $100 towards the purchase of a decent $5-$8,000 car. Someone will have to remind me of this promise, but if they do, I'll keep it.
Wow. That's really neat, hopefully they get the T. Tim
With the heat that radio generated they wouldn't need side curtains
Sorry Jerry. Hit this by mistake. Was trying to get to
OT- Christina is Miss July.
Thanks for the generous offer. I'll mention it to them!
Does the car have to run?
Does the radio have to work or is it a static exhibit?
Does the radio have to run off a 6 volt battery?
If it is an operating replica of a radio of the 1920's possibly the filaments will be between 1.5 to 6vdc (the A battery). There will be a B+ battery of 45 to 90 volts dc, and a C+ battery of 22.5 volts.
As this was one way communications it was a transmitter to the precinct station - a transmitter only.
The transmitter if operating a 5 meters will have the same power supply. Most likely the microphone will be carbon with a 3vdc battery.
FYI see: http://web.mit.edu/comm-forum/mit8/papers/Cohen_MIT8_paper.pdf
My guess is that the radio will not have to work, in fact it will probably be a mock-up.
Does the car have to run? I don't know, maybe not.
I remember seeing this picture when I was a kid a couple of years ago and always thought it would be cool to reproduce this car. Glad the DPD is doing it.
When you were a kid... a couple of years ago????
Model T's are for kids of all ages.
Alan, you are sooooo right! So there, Jerry!!!!
By 1920 the use of radios was regulated by the FCC. The call letter for the Detroit Police Department was KOP. Issued March 1922, they were assigned an AM frequency of 1050. From the information available the license was two fold - Entertainment interspersed with police broadcast.
Thanks for all the great info. I would like the car to run but it surely does not need to be a show car. Yes it will be a mock up. The antenna I have is a reproduction from 1967. They did a photo shoot with a Model T with the radio antenna and a new Plymouth Fury showing the advancement in radio cars. This first radio car was in fact a one way broadcast. The car would be on display in the hallway of out Headquarters building ouside of the museum. I would also like to take it once a year out to the Ferndale Emergency Vehicle Show the Friday night before the dream cruise.
sorry about the low resolution but it would not let me upload anything higher.
The Ford in the 1967 photo is a 1924 or 1925 model.
Who knew that there were fallout shelters below in 1924?
