Here is a Motorola CM-510 CB radio i just restored. It came from Motorola with a dark gray color. I put on a light gray.

Very cool!

I had a couple of the later Mocats in the late 70's, but that CM 510 is classic Motorola

Thanx for sharing

Up until I seen those pix, I thought the Mocats was the only CB's that Moto made.

Yeah, I had the black Mocat antenna on my black/white Torino...it was pretty slick. Don't have the antenna anymore, but I have 3 yellowing Mocat radios in the garage.

Oh, back in the day.....

Wyandotte, I did not know either.

alvine, they are in good shape..thanx for sharing

Motorola made there own power supply so you could use your radio for a base or mobile. This one i have is new in the box.

alvine · #11 (**permalink**) 07-31-2009, 6:35 AM

They also made there own mobile antennas. This one i have is new.

I have one of these!

I also have two Mocat 2020's, which are much more sensitive than the 4020 as half of the guts are missing in the 40 channel units. My 2020's now do 40 channels!

Those were very good rdios. The "Extender" noise blanker is the same used in the commercial two-way Motorola low band radios. It really takes the pulse noise out and lets you hear weaks signals. Two 2020's at 4 watts can go the distance.

Now you guys have me wanting to pull mine out too....the Mocats, that is (2020, 4000, 4022)!

Did you have the problem of the white yellowing, especially the mic? Is there anything that can be done abouit that?

Yes, I did. Even my Motorola Micor professional two-way stuff turned tan.

Motorola plastics improved in the early 80's with a non-yellowing formula, but that period was shortlived when they started to make cheaper parts (mics wihout a spring strain relief and metal /\/\ logo badge). Those were the best years (long gone). And the days of making radios with matching style mics, speakers, and control heads went out the door around the same time. The Mitrek was the last and the best for plasics, looks, and great radio design. Today it's a black box with a dingy underware colored mic...and a /\/\ that rubs off if you clean the mic one time.

No Way! you guys altered the faceplates and added in the Motorola logo! I never knew Motorola made a CB radio, What were the years it was manufactured and Where can I get my hands on one?

Hello Max Traxker:

Yes Motorola did make some really fine CB radios back in the day. I bought three of the mobile System 500 and a System 550 AM & SSB CB radios. Around 1972 to 1977, ballpark. I have seen the Motorola CB radios on E-Bay at times.

The great thing about the Motorola CB radios was the fantastic receiver they had, it had a kind of slow AGC and the IF was well filtered. The receiver had a special noise/pulse canceling circuit that allowed you to drive down the freeway with almost no noise. Allowing longer range contacts.

The Bad thing was the microphones they used, it was a dynamic type mic, that had many windings around a magnet, that the too fine of wire would break leaving the radio useless for transmitting. By slightly modifying a Commercial Motorola Mic, (which looked great!) changing the mic cord and transistor buffer type pre-amp circuit in the mic, and your back on the air. With a "tricked out" Motorola Commercial Mic.

Thats why I have a old Motrack without a mic.

I have modified several new looking Commercial Motorola Mic's for CB, Ham, and other radios. You usually can find them on e-bay or a swap meet, like the TRW swap meet in Los Angles. It does take some time to add in the up/down switches and other controls but well worth the time when your done.

I do not know if i posted a picture of my CM-540 or not. I just love this radio. I like the way it scans all 40 channels like a police scanner. I was told that the CM-540 is a very rare radio. I do not know if this is true or not. I was also told that the CM-540 was the very last Motorola CB radio that they made. Can anyone tell me anything about this. I would like to know as much as i can on the Motorola CB radios. Here is a picture of mine. Like i said i do not no if i posted a picture of it or not. So please do not get upset if i have posted it already. Thanks and have a great day.
