    An elderly gentleman who owned a Motorola dealership taught me the in's and out's of car radio repair during the mid-70's. He explained that they were forced to limit standard inductors to output circuits, RF (ignition interference) chokes, and tuning slugs. AM Auto radio IF circuits demanded "minimal length windings" because multi-frequency shielding was very difficult to incorporate into the transformer design, and that IF transformers almost always processed ignition noise better than the RF Oscillator/Detector feeds. Grounding of the IF can was a critical aspect of signal noise rejection, especially before resistive ignition wiring became available in the very late 1960's.
    I also remember antenna trimming as being extremely critical way back when...
    Hope this helps.

      Thing was, for some reason FORD engines in the early days put out one hell of a lot of ignition signal, you could see them on the television when they drove into our farm yard, but only the FORDS other vehicles seemed to have solved that problem. I thought perhaps the same was involved in the build of radios to put inside such a static producing rig. I can still remember the lines and the pop pop pop on the speaker when FORDS pulled in to visit. When they just drove by some would be strong enough to interfere but not strong enough to be that annoying. Since there were only 3 farms on our old country road there was not a lot of through traffic to be had.

    The reason for car radios having an RF stage and the 262khz IF is simple. A car radio must be able to operate in between cities where it may be subject to interference from stations close to each other on the dial. Normally the FCC assigns stations so that in an urban area no two strong stations are next to each other on the dial. However in fringe areas all bets are off. A car radio MUST be sensitive as well as selective, it must be able to operate far from any cities and strong stations. That's why the RF stage, to pull in the distant stations. And that's why the 262khz IF, greater selectivity due to the higher Q possible with LF IF coils. Actually, I'd have expected them to have TWO IF stages at 262khz as well, but that might have made them TOO selective unless the IF coils were critically coupled and you'd need a TV like sweep generator to align them.

    • @KennethScharf
      @KennethScharf 8 ปีที่แล้ว +16

      +shango066 Forgot to mention that with that 262khz IF they NEEDED an RF stage to have sufficient image rejection on the high end of the dial. Early BCB superhets ALL had an RF stage and an IF of around 175Khz. During the depression they eliminated the RF stage to lower the cost, and raised the IF to 455Khz (about as high as it could go) to keep image rejection good. But auto radio design called for a different compromise in design.

    Hi Shango. It Amazes me how people from other countries who have came here to live, care more about the goings on of our messed up government then most Americans do. You asked me once if I were a patriot, if loving this Country and hoping for something better than the lairs we call politicians these days makes me one than yes I am one. Great job on the radio repair.

      Hi Shango.
      No Nothing special about me. I am a nobody like 99% of the population .Never been rich,and I am not naive enough to think I can change the past or future. Things are the way they are and it's our own fault for not standing up for whats right. I have a Daughter and grand children, It's them I worry about. Though I know I can't do a damn thing about it. Not alone at any rate. You have no Ideal how many times I wished I didn't care like most. But yes you said you looked at my channel and wondered if I were a patriot, I guess due to my uploads and shares plus the many favorites I had.. I would like to see what this and other countries Could be. A fool yes, but no not a patriot if thats what one is as you stated.. Thank you for the reply. Take care.

      ***** America is *much* bigger than any politician, and will survive, the elected-and-appointed kooks who control its government. Things in America today aren't perfect by a long shot, that's for sure. But I will say that life in general is *a lot* better today than when it was, say, in 1967. This is from someone commenting here who was alive back then, perhaps others on this thread were around back then and remember those days, also. Think about all the advances in medicine, food production, automobile safety. Longer life expectancies, too! At the supermarket, adjusted for inflation, food in general, and produce in particular, is considerably cheaper now than it was then.

    I live in Mexico my 1964 beetle has a saphire radio it works with 6 vcd and a wire resistor to convert 12vcd to 6vcd, I made a complete restore and cleaning all the circuit plate and lubricate the tuning parts, the radio works and looks great.

    YEAH... So there it is!😁👍 The radio that brought to my ears FOR THE VERY FIRST TIME (Different Drum - The Stone Poneys). 1967 (on Linda G's) Volkswagen Beetle radio. (Her last name is "a color" that you get when you mix "Black" and "White" together. She was washing it in her driveway with the windows DOWN of course). I heard the Radio Station Jingle, THEN they "SEGGED" straight into it (with no talking over it) Excellent! ... WKNR... "Keener 13- Detroit"! I was 7 years old then. And, that song's been my constant companion ever since! (I looked in the Beetle, and YEP that was the radio)! I KNOW.. I BORED YOU, SORRY! :36

    The RF stage was ahead of the converter stage to maximize the radio's sensitivity so it could pull in stations in the most fringe conditions.
    Bendix was a major supplier of radios to Ford (prior to their acquisition of Philco) and Chrysler as well as Volkwagen. GM made their own radios at their Delco division in Kokomo, IN.
    If you think AM music stations are bad in your area, here in Central CT, in the daytime, there isn't a single AM that can be picked up that has music.All boring talk; conservative, liberal, news, foreign language
    . The only stations that have music are the Canadians that come in at night.

    If I'm not mistaken prior to 1967 the beetles I had were 6 volt?

    I used to ride out to Ft. AP Hill with a buddy in his VW Bug, they were quite the car. I went to buy one used once, but there seemed to be a lot of oil leaking from the engine after our little test drive, so I bought an Opel instead. Loved my Opel Manta, she was a great car, but not the same as a bug. As far as AM Radio, I grew up listening to it, as we still have no FM here although before the pandemic there was talk of a new FM station starting here, that would be our first FM station ever. I have simply converted to Internet radio using a little ESP32 hooked to a converter, then through an amp to a couple small stereo speakers. I can program in about 70 stations before I screw up the preferences file and have to start over. Sounds great, and I have it all running off 4 slab batteries I recovered from my old Macbook Pro after spilling coffee into the unit while camping in the Mohave Deseret outside Oatman Arizona.

    Nice Job on that. VW's are simple yet weird. I remember having to diagnose a no headlight problem on a '70s VW. Took me forever to figure out that they were on a fuse, not a breaker. Of course I had to order the fuse because nobody stocked those pointy ceramic things. I had to laugh out loud at AM 1230 👍 Sounded EXACTLY like the radio I remember... I hated it so much then, but miss it now. Brought back memories. Heck, even the DJ reminded me of my biology professor :D

  • @andrewagner9212
    @andrewagner9212 4 ปีที่แล้ว

    The RF amp is required because a wire antenna is used, not a ferrite rod. The IF is 262.5 for better selectivity and the output single for simplicity and no shortage of power, as you said.

    "Kiss You All Over" by: "Exile" was released in late summer 1978.
    Actually, "Exile" began their career around that time, as a "Soft Rock" band, and the song crossed over somewhat, onto the Country Charts!
    A few years later, of course; when "Exile" nearly went defunct as a "Soft Rock" band, they decided to "go Country" which gave them a whole new, successful, career!!!

  • @davewm9589
    @davewm9589 10 ปีที่แล้ว +1

    I think the RFstage may help with limiting radiation of RF signals from the LO. Cars close to each other with converters close to antennas might be a problem. A good test would be take a RF amp radio and put it close to another, then try the same with a non RF amp radio.

  • @algrabenbauer
    @algrabenbauer 8 ปีที่แล้ว

    I think that there is more voltage gain in the lower freq IF stages than in 455 or 10.7 mhz used for FM. The other comments are right about the use of an RF amp for sensitivity. However I think the reason for the lower IF frequency is so they can use lower frequency for the local osc . The lower freq of IF - the lower the beat freq osc has to be. This makes it much easier to match up to using all slug tuned tuning coils. They were also easy to make the mechanical memory possible. Try tuning a variable capacitor radio in a bouncy car and keep it tuned. Also with the lower IF freq some of the higher audio freq are lost giving a cleaner sound while the engine is running.

      Build yourself a little internet radio, you can get stations from, well nearly everywhere by programming your preferences file. I have mine set for many great US Stations as well as German, Swiss, Netherlands, and one from Russia for that Marshall type music. Lots of them play old time radio programming with plenty of old Suspense, Lone Ranger, Have Gun Will Travel, the Great Gildersleve, Fibber McGee and Molly, that sort. Sure brings back the memories. One even plays recordings from Armed Forces Radio from Vietnam, I listened to AFVN for 13 months solid when I was in Nam on my little portable radio, man does that bring back memories.

    About the 262.5 IF. I had an instructor comment about that once, and I don't remember exactly his thoughts. I want to say it had something to do with making the IF transformers more rugged. Different gauge wire perhaps. That's all I can come up with right now.

    I built an 'ESR' meter, which uses an AC signal to measure up to 100 ohms, and has a list of values that indicate OK for a set of electrolytic capacitors and their respective working voltages, but the ultimate comparison is that of a new one, with that of the old.. By simply bridging with an electrolytic only a fraction of the desired capacitance (just 47uF, over where a 1000uF should be) with such great effect, was the turning point in diagnosis.. Perhaps the radio should have more 'air cooling', as in the engine.. ..especially with a 'class A' audio output..

  • @OlegKostoglatov
    @OlegKostoglatov 10 ปีที่แล้ว

    I think that the purpose of an RF amp in a car radio was noise rejection, I've noticed the same feature in a lot of tube car radios as well, it certainly helps with noise rejection in a house radio, and in the case of a tuned RF amp stage it also makes it more selective. As for the 262 KC IF frequency, with also means a 262 local oscillator frequency, I can't say what that would do for interference or noise reduction, it would make the set more selective however. In terms of tube based car radios some used a 262 Kc IF, but I've run into others that used a 455-456-460 Kc IF as well. Also most tube car radios seem to use a push-pull output stage, usually 6K6s or 6AQ5s, I'm not sure if they were class A or class B amps however. A lot of car radios use permeable slug tuning, though some used tuned capacitors, almost every pocket transistors radio I've seen used a tuning cap. With a slug tuned set all that the have to do is add another coil, with a capacitor tuned set they need a third section in the tuning capacitor, and a coil, so that may explain why they added an extra IF amp stage and transformer.

    You are correct about why the Circuit differences between Pocket Radios (& House Radios vs Auto Sets: high interference rejection. Noise from Auto Generators & the Ignition primary & secondaries. . an Ocean of interference under the Hood & Signal variations while driving under Bridges & etc.
    You are correct for the most part; The Media Corporations that buy up AM Radio Stations kill off the good Music formats & substitute God awful endless "Info-mercials" & pointless Gab sessions.

    Perhaps one of the reasons for the single-ended output stage is so that the return wire from the speaker could be connected to the chassis of the car and use the car's ground as the speaker ground. (and cheap out on a piece of wire...)

    The only place where music on AM radio works is in the rural areas of the country, where FM can't travel very far. Believe me, when you're plowing the fields in the spring, the most annoying thing is when you get down in a low spot in the field, the FM will go out before the AM does.

Of course this was back in the mid 1960's I am sure things are different now, my Uncle had machinery dating back to the 40's and early 50's on his farm, nothing modern, his pickup was a 49 Ford.

    I am trying to troubleshoot a Philco Ford AM only radio out of a 1967 Ford Mustang On the side of the radio its marked 7TPZ . It powers up and has audio but its squeal with static like
    its going into oscillation. With a 5 foot piece of wire I could get a local radio station weak not clear. If I connect it to my outside wire antenna the station drops out as though the radio was overloaded. I have been searching for the schematic but so far no luck. I checked the only 3 transistors with a meter in the diode mode and they look good. There is a germanium diode that measures good too. I certainly would appreciate anyone offering a schematic. I might be able to fix this. There is one large round capacitor. It looks like a multi-capacitor. I noticed
    its corroded on the top. Could use help with a schematic. Thanks

    Why is it always a problem with the capacitors?

    • @rodolfogomez382

      Due to their construction all capacitors are degraded on time, specially old paper-waxed and electrolytic capacitors, but also resistors and transistors are degraded; if you restore a radio you should check all them.

      It's probably not always capacitors. Electrolytics, maybe. Other times it's tubes, diodes, transistors, resistors, etc.

    Would you happen to know of a place that repairs radios that you trust? Maybe even yourself? Please advise.

      I'm looking at a Zenith TransOceanic from the late 1940's, and I'm in the St. Louis area. I'm willing to ship it, but I'm also willing to try a local place too. I'm willing to drive 50 miles to drop it off IF you know of someone you trust in the St. Louis area (but what are the chances of that?).

      You are going to end up spending hundreds of dollars on something you will only really be able to use on the broadcast band. Shortwave is diminishing fast, there are fewer and fewer stations every year. If you ship it to me its going to cost you a minimum of 200 for the shipping and repairs.

    what is the small #4 on the dial?

      represents 540 kHz, low end of the dial.

    How odd there is a classical music station on AM. How do the classical snobs tolerate that?
