Motorola CB radio - go ahead.....

[High_order1]

.....and flame away. I know. Been a LONG time since I've even really thought about childrens' band. HOWEVER, the other day, I was tooling around a new junkyard in Knoxville, TN when I spied this huge jack under the dash of a Lincoln Continental. It piqued my curiousity. Out of the glovebox fell a HHCH and a book entitled 1980 Ford 40 channel CB Radio with memory (no less).

30 minutes later, using only my Leatherman, I was the proud owner of a factory Ford CB, to be installed in my 2005 SUV, because if for no other reason, to have people ask me HTF can you get a CB as a factory option.... lol Plus, I like radios, and this is kinda neat to me (go ahead and rag me, I like radios...)

The remote part in the trunk says it is a Motorola Inc. FCC Data CB 1184. There is a bunch of Canadian DOC approvals.

I tried to search the FCC ID database using CB1184, with no luck. Tried to find a Canadian analog, no joy. Went to a lincoln enthusiasts site, and asked for a wiring harness diagram, no luck.


There aren't five wires that actually tie into the vehicle. Two are the same color, and I am betting they are speaker out. I suppose the remainder could be COM, +V, and ACC SENSE, but which is which? I cracked the case, but there are three seperate boards, so I can't just trace 12 volts and ground without a bunch of extra disassembly.

Oh - the CB interfaces with the vehicles' antenna using a BNC.

Anybody got any klew on which wire goes to which? I can go out and get the wire color codes if that will help. Otherwise, I am going to take it apart further and go from there.

Ideally, I'd like to find a radio schematic, but I'm not holding my breath.

Come on, good buddy? (heh)

Great find, be sure to get some good photos of it....

[witthoft]

Yes, please show pictures......

[techie]

Hmm..
HHCH similar to A3 spectra? I saw a /\/\ CB like that on ebay a while back..

You can try checking continuity from RF ground to DC ground..

[kf4sqb]

Shawn, post the wire colors. That may help. You may also want to check out the antenna matching section in the rig. Unless there was a factory installed CB antenna as well, and I'm guessing not, it probably hooked in with the stereo antenna. If so, the tank circuit around the final RF amp may have been specially designed to allow it to work with the car's stereo antenna. You may have to do a little redesigning, or hook it to a stereo antenna for it to work correctly. Go back to the car it came out of, if possible, and see if the original "interface box" that tied the CB to the antenna is still there, if you didn't already get it. The insides of it may give you some clues as to how it is designed. If it is nothing but a bandpass filter to separate the 27 MHz signal from the FM stereo signal, the radio is probably designed to work on a stereo antenna. If it appears to have the bandpass plus a loading circuit, you should be fine attaching any CB antenna to it.

Oh, also, as has already been suggested, post pix! I want to see this beast!

[High_order1]

Thanks for the tips!

I'll get some pictures shortly. The Control head looks like a DEA radio control head and a Norelco shaver had an illegimate child.... LOL It uses a Velcro hangup as a factory standard. I thought it was a repair, but then I found a pic of the CB with the factory UHF wireless telephone, and that one was Velcroed, too.

The radio connects to a thing that looks like an oversized can bolted to the retractible antenna. BNC and an old style moto in, to an old style moto out. I got it too, just in case I couldn't get the SWR figured out, or like you said, it was only designed to work with that specific matchbox. (Yes, I almost got locked in the trunk, but until they start a survival forum in here, that's a post for another place.... LOL)


OH - I got a few PM's about the junkyard. It is the CRAZIEST place I have ever seen. Really. Forget all you know about junkyards. It is like Dollywood for car parts. There are no weeds, no chiggers. Its' all gravelled. There is a sink to wash your paws after you yank the parts you want. The parts are priced by what it is, not where it came from. So, an alternator out of a 1970 pacer is the exact same price as a 2000 grand am. Seriously. That's why I went, I thought my buddy was lying. The only thing this place lacks is a beer fairy to drive around in a golf cart selling beer and hotdogs. Oh, and the prices - $158.40 for an 8 cylinder engine WITH WARRANTY. A/C Compressor $17.95 WITH WARRANTY. No searching for the car, there is a computer system. Has a picture of a girl with big hooters holding up two round headlights. You punch in the car you want to see, it PRINTS you a ticket of the exact row it is on. Don't have your car, they say if you'll tell them, they will get it and call you when its' in. (I tested that, I'll let you know when I hear something).

They have a website: http://www.pullapart.com , and its' on rutledge pike a few miles past the concrete plant. I HIGHLY recommend it (and no, this isn't a paid endorsement. I just promote the places that actually DO what they SAY).

[jackhackett]

Looks like they don't have that on their website

[High_order1]

Sorry about the lack of, uh, headlights dude. They make up for it on site. There is a huge one pointing towards the place.

Pictures!

This is what I am supposed to look like according to the manual:



And, this is what a Radio Man is supposed to look like:



Don't laugh - the picture of the box is what helped me find it in the trunk amidst the audio amplifiers and other junk.

This is the complete kit; control head, harness, box, and antenna adapter:



this is a closeup of the microphone:



You can't really get a good idea of the shape of it from that picture, so here is a profile shot:



Notice the TX button on top?


Anyway,

I stopped by the local dealership. They don't keep service manuals from that far back. They were trying to laugh me out of there when I said, "it's too bad - my granny needed a buncha stuff done on her Continental". Oh, THEN suddenly they had some pre-1996 knowledge, but I said, hey without the manuals, how will you know what to do? And left.

I found some more numbers:

TM-D 84D40631R01 R02 on the recieve board;

E 0AF-19A195-AB which I am betting is a Ford p/n;

and

5FD80064 or 8O064 which I suspect is a Moto ID.

I am pestering some CB sites that claim they have all the Sam's Fotofacts from back in the day to see what they may have, and I've emailed a few people selling the 1980 Lincoln Continental Electrical Service Manual on eBay to see if I can just buy a copy of the wiring page I need.


-Shawn

[High_order1]

The wiring colors:

Four wires on the front of the harness - marked 886 9MA

- Yellow with Black spots

- Green

- Lt Blue with Green Tracer (there are two of these)


One wire exits in the rear of the harness - marked EOVB 18A919BA ELIKAN

- White with Black spots - ran into a single terminal connector (I expected it to run to sheetmetal ground).


-Shawn

[kf4sqb]

Shawn, I would have to guess that you're correct in guessing the black/white wire with the terminal connector is ground and the two blue/green are speaker out. I'll talk to my brother tonite at work about it. He's more familiar with such things as stereo wiring harnesses and the like, and I'm betting that Ford had Motorola color the wires to their specs. I would guess the yellow/black is memory (constant hot) and the green is sw. B+, but I can't say for certain. If my brother has no idea, I may swing by the local Ford dealer here in town when I get off work in the morning and see if they have any info on it for you.

[kf4sqb]

Shawn, I've had no luck so far. The local Ford dealer also no longer has any manuals that old. However, I know where all their old manuals are; they donated them to the local tech. school. I stopped by there after I left the Ford dealership, but the instructor wasn't there, nor has he been there for the past two days, nor does anyone know where he is or when he'll be back. If you haven't found out anything in a couple of days, I'll try again to contact him and see if he can help out. I did talk to my brother about it, and he agrees with my guess about what is what, but we in no way warrant this information. My brother did suggest to go back to the junkyard with a battery (something like a lawnmower battery should be sufficient), if possible, and hook it to the car's electrical system if too much of it isn't missing, and see if you can determine what's what that way.

You may also be able to hook the radio to a power supply with a variable output, through a very small fuse, like maybe a 1/4 amp, to what we think are the correct wires, and slowly bring the voltage up. If you see what you think is an excessive current draw, or if the fuse blows, its probably not the right wires to apply power to, or else the polarity is backwards.

[brscomm]

I just saw someone on ebay selling both a regular Motorola Mocat and a "Ford Aeronutronic" version that was housed in black. It sold but if you look up item #
200142434282 you should be able to see it.

[MTS2000des]

I had the Mocat 40 I picked up at a thrift store, FWIW it had an issue with the modulation, and took it to a local CB radio guru. He advised me that radio was actually made for Motorola by Uniden, and IIRC he had the Sams photo fact on the radio- and mentioned that all the Motorola CB's were OEM'ed by Uniden- I will see if the guy is still in business (this was about 4 years ago) and if he has any info on the radio you have Shawn.

[High_order1]

Thanks guys!

So far, I have gotten about a half a dozen emails all saying they either have never heard of it, or they don't want me to pay them to xerox a page out of their manual.

ah well.....


-Shawn

[brscomm]

Some models were built for Motorola but the AM Mocat 23 and 40 channel units were built by Motorola. The quality of construction and P/N's on various parts leave no doubt.

[High_order1]

Well, still no joy. People selling the manuals on eBay want from 15 to 30 bucks to scan and email me the single page. I am in the wrong business. I have a lead on a schematic, hopefully,this company will return my email. Trying to get back to the junkyard before they toss the car....
Ah well, we press on.


-Shawn

[kf4sqb]

Shawn, as I said earlier, I will try to go by the local tech school in the morning. They have all the local Ford dealer's old service manuals. I'll post back here with whatever I find out as soon as I get home in the morning, around 8:30 AM, hopefully.

[kf4sqb]

Shawn, sorry, but the instructor at the local tech school says he got rid of all the old manuals he had a few years ago. I really don't know where to go from here, aside from what has already been mentioned.

[jackhackett]

Sort of OT... but in response to an earlier post:
I worked on a few Mocat CBs, and I never saw one that bore any resemblance to any of the Unidens, they may have made them to Moto's specs though.

The Mocats were different from most CBs in that they used mics that got power from the radio (like all of our favorite Moto mobiles), it was fed to the mic hi pin through a little choke that had a habit of burning up, causing you to lose tx audio.
Another thing about them, most synthesised CBs used a dedicated synthesiser IC, IIRC the Mocats had a synthesiser made from a number of discrete logic ICs.

You do recall correctly. Before the 40 channels came out, we cut the plating on two of the IC pins that were tied to 5 Volts (I don't remember which IC or pins). Then we tied those pins to the dimmer switch and the extender switch to toggle between high and low. We were able to get into the 28 MHz area. Power dropped and became spurious and rcvr sense went pretty bad but it still worked. We did this in the factory lab on the original 23 channel Mocat before its release to the world.

[kf4sqb]

Shawn, just as an idea, have you tried checking with some of your local auto-parts stores for a wiring diagram of an '80 Lincoln? I would think that your best bet would be one of the older chains, like NAPA.

[High_order1]

Well... tentatively, a guy on ebay has sold me a diagram for ten bucks. That's reasonable I suppose. And, I paid for, but have yet to recieve, a schematic from another place. We'll see....

But it sounds like Dave aught to have this data crammed into a nook somewhere, huh? lol


-Shawn

[Max-trac]

I have a Mocat, but it is BLACK!! I think it has a Ford label too.....
Maybe I will dig it out for pictures if anyone wants....

[High_order1]

WELL, the one guy came through and I have a scan of how to install it. Hopefully the other will so that I can align it properly....

http://www.kenselectronics.com/manual/indexM.htm

Ford 80-2 models 5FD8002 thru 5FD8028 . . . . . . . factory Service Manual


Looking at the scan, I have to go back and get another part. There is a CB / AM/FM radio interface that will switch the speakers over when the CB unmutes. That could have some applications with another project I have....


I appreciate everyone's help!!!

[High_order1]

Ok, now here's something you moto guys can help with. I was searching by the patent numbers in the box, when I found this:


Motorola Service Manual, Aug. 1980 Entitled "1980 Ford Remote CB Radio 80-2"

Apparently a guy named Richard T. Skill was the brains behind this project.

AND

I learned Ford Aeronutronics did a lot of defense spook tech, including hovercraft....

Anybody have some antique moto manuals?

-Shawn

[KitN1MCC]

my friends 1978 jeep cherokee

rest here http://s32.photobucket.com/albums/d20/kitn1mcc/benty/

[High_order1]

That's cool. I found the patent for that case, guess they were afraid of copycats or something.....


-Shawn

[Max-trac]

Here is the Ford Aeronutronic 4011 Black Mocat CB;

[High_order1]

well..... it works....





I'll have to use an amplified speaker, and I am still waiting on a schematic to align it, but at least it works......


-Shawn

[KitN1MCC]

i like the ford shadow color


the mocat is a good radio and works great my friend has an ssb base at home

[kf4sqb]

Well, Shawn, were we right on the wire colors?

[High_order1]

mostly. Everwho said the case is the ground gets a banana. Single wire to the rear is B+. Front yellow with black is ACC SENSE. The two we talked about is audio out, but on an 8 ohm speaker, it's quiet so I am thinking line out. Remaining wire is a trigger for the radio system, when it pulls hot it preempts the AM/FM and ports CB audio through the system.

I am still hoping for that manual, but I definately appreciate all the help!!


-Shawn

[kf4sqb]

Hmm, interesting. I was wondering if maybe the audio output was to tie into the stereo and use it's speakers. Well, I'm glad you managed to get it all right, and didn't fry anything!
