Hi,I hope this is the right section to ask this question. I recently bought a model 307 radio for my 1960 Dodge. I believe this is the Astrophonic model as it has the solid black face and illuminated push buttons. It also has the plug for the optional record player. It has 1960 knobs and doesn’t say “Astrophonic” as the later versions did. The person I bought it from told me it came from his dads 1960 polara.

I can’t seem to find any info on the model 307 radio when I search online. Can someone here give me some info on my radio? Thanks in advance for any info.

From allpar:

"Dodge radios were transistor based for longevity. The new Astrophonic offered was almost five times more powerful than the standard radio, and it had an extended range and better fidelity. It had three transistors and a rear-seat speaker, along with illuminated push-button controls. The new Dodge Music Master radio also had push-button controls."

Hi,Thanks,it’s identical in every way to the mopar model 302 radio shown in the link you attached,mine says model 307 on it though,which is what caused the confusion looking it up. Nothing is shown under that number.

I will take pictures this weekend of it.

There is no Mopar 307. There is a 302 and a 305 listed for 1960 Dodge.

That’s what I thought too. It’s exactly the same radio as shown under Mopar 302 in 56d500boys reply,yet it is stamped MoPar model 307. I searched online and could never find anything on it so I figured I’d ask here. Any chance it could be Canadian? I’m not sure if they used different part numbers or not. I’ll try and get some pictures this weekend.

This one is actually a 1963 Dodge 880 radio. The all Transistor models didn't hit the market until the 1963 models. Otherwise they look identical to 1960-61 Polara radios. This info. comes from Rick Hirsch who has done extensive research on Mopar transistor radios.

Both the Mopar model 302 and Mopar model 305 were "exactly" the same radio, which were both made for the 1960 Dodge models. Both of these radio models were Transistor-Powered  or Transistorized, which its circuitry contained (3) low-voltage space charge vacuum tubes and (3) power transistors. The Mopar model 302 was made by Motorola and the Mopar model 305 was made by Bendix.

It was not until 1963, that Chrysler's Dodge Division had started to use an all-transistor car radio model, which was called "Astrophonic All-Transistor" and it was labeled on its radio glass dial.

Finally I have "attached" radio manuals for Mopar models 302 and 305.

I hope that the above info will help you.

I noticed the Motorola radio has the audio amp transistors visible mounted on the top of the front bezel, the Bendix one does not.

You are correct Norm, with the fact that Motorola had mounted their (2) Audio Output (push-pull) power transistors on the top of the radio. Bendix had mounted their (2) Audio Output (push-pull) power transistors on the side of their radio model.

When I was referring to the fact that the Motorola and Bendix radio models are "exact" same radio, I did not mean it literally. I was referring to the fact that both Mopar model 302 and Mopar model 305 have used the same front cabinet face plate, tuning/volume knobs, and push button designs. And, both of the Mopar models had also used the same "transistorized" circuitry design, which both had used (3) low-voltage space charge vacuum tubes and (3) transistors.

Also, there are some other "minor" differences between the two radio Mopar models in its circuitry design. For example, each one of these two Mopar radio models had used slightly different low-voltage space charge vacuum tubes and transistors complement numbers. And there were also some other "minor" differences in each of their schematic designs, but overall both of these two Mopar radios that were made for the 1960 Dodge models, looks the same and also basically worked electronically the same.

Chrysler Corporation had used several different radio manufacturers for supplying all of its car radios. In 1960, the main radio suppliers were Motorola, Bendix, and Philips (Canadian models) for its Dodge Division. All of these radio companies would make the same car radio models, but each radio manufacturer would use different Mopar model numbers.

I have "attached" a photo of a 1960 Dodge "transistorized" Mopar model 302-Motorola and also I have "attached" a photo of a 1963 Dodge AstroPhonic All-Transistor  Mopar model 350 -Bendix. Note: Both of these radio photos were taken from my archive's reference files, but I do not own them.

Finally, "thanks" Norm for your comments and also for sharing the photo of your Mopar model 334 -Bendix AstroPhonic All-Transistor, which is for a 1964 Dodge model.

At least there is enough difference to be able to tell the manufacturer. Makes a difference when servicing them for sure. I liked the Motorola booklet that shows the the model 102. It only has one output transistor, so must have been single ended output instead of push-pull. I wonder how much cheaper it was to buy that kit? I also see the Bendix kit had noise suppressors included. On my 64, my dad had the radio repaired in the 70's, and installed a new speaker. The radio was gone when I got the car back, (I think when I was a kid I stole it for another use ), and the speaker cone had disappeared completely!

I had found the factory 1960 Dodge Service Manual and it only list (4) Mopar transistorized "hybrid" car radio models for that year, which I have also uploaded its page and there is NO  Mopar model 307. Hopefully, "Suddenlyits1960!" will reply back to this thread and post some photos of his radio ?

Sorry Rick for the delayed reply. I’ve been extremely busy and had forgotten all about this post and haven’t logged in here until yesterday. I made time this morning to take some photos of the 1960 Dodge Astrophonic radio and as you can see what I stated is correct,it IS indeed a MoPar model 307,which isn’t supposed to exist,but does. The person I got it from told me it came out of a 60 Polara. Hope someone can shed some light on this unusual model.

Edit-I have attached photos below but can’t figure out how to add the pictures show they show up automatically in the thread. You have to click on them to view them. Can a fellow Forward Looker tell me how that’s done or post them here for me so they show up without having to be clicked on? Thanks

Based on the service docs shown above, it appears to be a Motorola unit, as the amplifier transistors are mounted on the top of the face bezel.

Hi,you’re right I believe it is a Motorola unit. The transistors have the Motorola logo on them too and they are mounted on top of the radio. I’m glad I was finally able to get around to taking the photos since everyone kept saying there was no such thing.

I am curious,does anyone know the reason why the 305 model was made by Bendix,and the 102 & 302 (and 307) were made by Motorola? Why not just have Motorola make all four models?
It will be interesting to hear “electricalengineer”’s take on the radio that’s not supposed to exist. I wonder what,if anything (besides the model number) differentiates it from the 302.

Can anyone here recommend someone to recone the original mopar speaker? I know you can buy modern replacements but it would be neat to use the original speaker.

Since this Astrophonic radio also has a plug for the optional RCA record player,has anyone here ever made a plug so they could play another music source such as an iPod or MP3 player through it,or would that even work?

Hello Suddenlyits1960!

                 "Sorry" for the delayed reply. As you could tell by my post counts, that I do not spend a lot of time on the Forward Look website, for I am very busy with all my research projects and seem to have very little time available for anything else. But, there are many other knowledable members that are regularly on this site and should be able to also help you. 

I also want to "thank you" for uploading your photos of your Dodge Astrophonic Mopar 307 radio, for I have never seen one before, and which you had also said that it came from another 1960 Dodge Polara. To be honest with you, I had never doubted that you actually had a Mopar 307 model car radio. But, I was a little baffled when you said that it was from a 1960 Dodge Polara and also when I had checked my 1960 Dodge service manual that only listed the "Music Master" Mopar models (102, 106) and "Astrophonic" Mopar models (302, 305), which are all transistorized-hybid car radios.

Unfortuantely, I do not have the 1961 Dodge service manual, which I think that it was only a supplement to the original 1960 service manual, so I could not check further. But, what really threw my off, was the fact that you had originally mentioned in your opening statement that your Mopar 307 model also had 1960 radio knobs. This is the main reason why I actually want to see your Mopar 307 radio model, for the Dodge radio knobs for the 1959 and also 1961 models do not look anything like the 1960 Dodge radio model knobs and the also for fact that my 1960 Dodge service manual did not list your Mopar 307 radio model in it. Then, when you had finally uploaded your photos of your Mopar 307 radio model and I saw that indeed it did have the 1960 radio knobs as you had originally stated, then I was really thrown for a loop !

I finally had called a couple of friends of mine, who were former Motorola electrical engineers, and one of them was able to do the research and find a "one page" Motorola document that was dated 11/60 and it had showed the "mysterious" Mopar model 307, which stated that it was used for the 1961 Dodge car models. Also, in this Motorola document it stated that all of its electronic circuitry was "similar," with only a few minor part changes, to the 1960 Mopar models 302 and that you should use this schematic when servicing it. In another words, there was no separate schematic avialable from Motorola for the Mopar 307 radio model. One other important statement that was also made in this Motorola document, was that it had mentioned that the Mopar 307 had used "different" radio knobs than the 1960 Motorola Mopar model 302.

I also had my friend email me several close-up photos of the different sections of the Motorola one page document, which I have also "attached," for his scanner was not working. He had also mailed me the document and I should receive it in a few days, which I could also uploaded this document if you still need it.

I have also "attached" the engineering electronic schematic for the 1960 Motorola Mopar 302 Astrophonic radio model, which is very "similar" for the 1961 Motorola Mopar 307 Astrophonic radio model. After a close examination of this schematic, I had discovered that the Mopar model 302 actually uses (4) minature 12v (low-voltage) space charge vacuum tubes and (3) transistors in its circuitry. I had originally stated above, that the 1960 Bendix Mopar model 305 and 1960 Motorola Mopar model 302 models had used the "same" transistorized circuitry designs, where I should of said "similar" transistorized circuitry designs. The Bendix Mopar model 305 had used one dual combination low-voltage space charge vacuum tube for its RF/Converter stages and the Motorola Mopar model 302 had used two separate low-voltage space tubes for its RF and Converter stages.

Finally, I also believe that you got this radio from someone's father, who used to own a 1960 Dodge Polara. But, I believe that somewhere along the 60 years, the radio has been changed to a 1961 radio model, for probably its original radio was broken, and the previous owner or dealership had replaced it with the Mopar 307 and also just used his original 1960 radio knobs since both radio models looks exactly the same from the outside ? 

Maybe, Dave (56D500boy) or someone else might even have the 1961 Dodge service manual and could see if your Mopar 307 radio model is also listed in it ?

Lastly, I hope that all the above information is helpful to you and I also want to thank everyone who has participated in this thread so far.

Rick

Who? What? Where?

I didn't do it!!! The sun was in my eyes!!!

To quote Sargent Schultz from Hogan's Heros, "I know nothing. I see nothing".

That said, Troxels have a 61 Dodge Owner's Manual and eBay has a 61 Dodge Service Manual:

"Thanks" Dave (56D500boy) for your suggestions. Dave is definitely a very resourceful guy, especially when you need any Dodge car materials.

However, I am not sure that the 1961 Canadian Dodge Service Manual will have the 1961 Motorola Mopar model 307 car radio in it ? The reason is that Motorola and most other U.S. car radio manufacturers would manufacture an "Export" car radio, which will have a different Mopar model number, for its other (not U.S.) retail markets. Also, Chrysler of Canada had used Philips Electronics to manufacture a lot of its radios for its new car models and they will also use a different model number for its radios.

I think that maybe your suggestion of the 1961 Dodge owners manual is a better choice and it might also show the different radios. along its Mopar model numbers also ?

I also had found on ebay the U.S. version of the 1961 Dodge Service Manual supplement and it will probably have the information for the 1961 Astrophonic (Motorola Mopar 307) car radio. Maybe Dave (56D500boy) or someone else might have this particular supplement manual ?

(BTW, I like your Hogan's Heroes humor) !!!

Finally, I forgot to reply back to Suddenlyits1960! question on why can't Motorola manufacture all the car radio models for the 1960 Dodge car models, instead of having Bendix manufacture some of them. The answer is that Motorola can, but Chrysler Corporation will not let this happen. The reason is that most car manufacturers will always have at least (2) different outside suppliers to manufacture their specialized equipment for all their new car models. And the reason for this, is to insure that there will be no delays due to part shortages or work stoppages from any strikes that might occur.

Thanks again for the member's replies and all the information given-Rick

Sorry it took me a bit to reply... Wow! Thank you so much Rick,“electricalengineer” for your exhaustive research on this 307 radio.So it’s really a 1961 Dodge radio then? Now I feel kind of let down because I can’t put it in my 60 Dodge as it’s “not correct” lol! Glad I was able to share something unusual here,Thanks for all the effort you put into researching this for me. I am curious,what did the original face and knobs look like? When you get the photos from your Motorola friend can you post them here? Any chance a late production 1960 Polara could have had this radio factory installed?

Thanks again to “56d500boy” for helping me out by posting the photos here. This is a great site.

The "face" was the same for many years,,, even my 64 is very close to yours, except it has "astrophonic all transistor" in gold on the plexi face.

I have the 1961 supplemental factory service manual and will check to see if it contains any info on radios. If yes will post a photo of that section. In general the 61 FSM focuses on the differences between the body / drivetrain and doesn’t contain a lot of detail. In fact it will reference the 1960 FSM for in depth detail / instructions.

The outer chrome bezel with the “Dodge” name is the same for all 1960 - 64 Dodge models.
The 63-64 models referenced are Custom 880.

What changes is the radio and faceplate. Also some 63-64 Custom 880’s use two black “L” shaped pieces that mount to side of radio. Basically so it matches the radio face. Where’s the 60-61 models have a silver plate behind the clear faceplate.

Hello Suddenlyits1960!

      Basically, for each car model year, they will use a different radio model number, and therefore the 1961 Motorola Mopar 307 "Astrophonic" 5 1/2 watt car radio model would not be used for a late production 1960 Dodge Polara car model. However, the Dodge Dealership could of replaced the 1960 Motorola Mopar 302 "Astrophonic" car radio at the end of the year 1960, due to it being defective, with the newer version 1961 Motorola Mopar 307 car radio model.

Also, both Mopar models 302 and 307 looks exactly the same from the outside, except for its volume and tuning knobs. And the inside circuitry is also almost identical, and that is why the Motorola document for the Mopar 307 had stated to refer to the 1960 Mopar car radio model 302 schematic for servicing. 

For the 1961 Dodge Polara car model year, there were (2) "Astrophonic" car radio models used, which were the Bendix Mopar model 306 and the Motorola Mopar model 307. 

Finally, I have "attached" a photo that I had in my archive research files, which is a Chrysler Corporation factory photo and it shows the interior dashboard of a 1961 Dodge Polara car model with its "Astrophonic" car radio. You will also notice in this photo, that the radio knobs will "match" the car's other dashboard switch knobs, which are for headlights, wipers, interior-map light, and cigar lighter. 

Thanks again for all of the member's contributions and I hope that all of the above information is useful to you.

Rick

Here is the section from the 1961 Dodge FSM supplement for accessories. This is the ONLY page in the entire manual that references radios.

The one paragraph in section "Group 1 - Accessories"
Note that it states all radios are the SAME as the 1960 models.

That factory photo posted by electricalengineer showing the 1961 dash is interesting for a few reasons.
It's definitely an early version. If you look closely it has the cutouts and matching chrome trim for light pods that mount behind the dash and illuminate the switches.
This option was only available on the 1960 Dodge Polara and 1960 Desoto models. To the best of my knowledge it was NEVER offered on a 1961 Dodge model.

This is not uncommon for the factory photos to show an option, trim package, molding etc that wasn't offered since many times the photos were mock ups of the cars pre-production

Hello Space Trukin Wagon and thanks for your upload of your 1961 Dodge supplement manual-page 5. However, you had made the following statement that is quoted and highlighted above in "red lettering " and when I looked at your manual's page 5, I do not see anywhere on the page saying what you had stated above ?

Are you saying that the 1960 Dodge Polara cars that had used the "Astrophonic" Bendix Mopar model 305 and Motorola Mopar model 302 car radios, which are shown and listed in the 1960 Dodge Service Manual, uses the "same" radio and Mopar model numbers 302 and 305 for the 1961 Dodge Polara car models ?

Thanks Rick

Hello Suddenlyits1960!

                I have attached the Motorola Mopar radio model 307 document that I finally got from my friend and I also had attached the Bendix Mopar radio model 306 schematic, which both of these "Astrophonic " car radio models were for used the 1961 Dodge and Polara car models,  both of them had also used the Transistorized - Hybrid (low-voltage space charge vacuum tubes and transistors) circuitry.

These two new 1961 Dodge "Astrophonic" car radio models have superseded the 1960 Dodge "Astrophonic " car radio models Motorola Mopar model 302 and Bendix Mopar model 305. 

Finally, I hope that all of the above information has been helpful to you and I also want to thank everyone for their information and contributions towards this very interesting thread. -Rick

Agree, a lot of good information on the radio options for 1960 & 1961 Dodge models.

I went back and double checked both the 1960 FSM and the 1961 FSM the ONLY difference between the 2 in reference to radios is the line mentioning the “radio wiring diagram”. That “radio wiring diagram” is included in the 1961 Dodge supplemental FSM. Specifically it’s a wiring diagram that references a model 306 radio. There are no references to model 307 radio.

Hope this additional info is helpful.
