I'm just learning how to make RUclips videos and on Bitchute. My mentor talks fast on telephonically and I forget how. Obviously that's what the whole thing depends on! I'll try again, Mike!
Radios have always seemed to be a mystery when looking at them. My switching supply that died is the same. Yet, I am an electronics technologist. I focused on digital technology instead. I'd love to know what equipment you have and use to repair, measure, and re align radios, especially for SSB. (And now FM since they added it officially to CB.)
How I could find a way to get in touch with MIKES RADIO service 2 cobra 2000 GTL, radios of mine, .. there all together, i use one , the other one the frequency counter to flexing . I would both to be serviced and be set up as from factory, hope both has not been ( over) modified . Thanks for re-breathing life vintage radios, Thanks again,, hope to hear from you.
Mike don't cut your income by half just to make the course, We'll learn in good time. I've already learned quite a bit just by watching the videos you currently put out. Thank you for these videos.
A man once said to an upcoming CB tech.... "its much easier to fix radio's if they are completely dead" , so the new Tech went to his bench and promptly reverse polarized all his incoming repairs ......... boom boom
Mike: Super video!! I also have an RCA Co-Pilot 14T302 SSB, but mine works!! I'd really love to see a video on you working on this radio! I can't wait for the electronics course too!! I'm counting the days, brother!! Your humble subscriber, Norman in Montreal.
Strange ... in Russia CB radio is almost dead , nobody needs it . All use GSM phones and mobile apps to communicate. Friends are perplexed when they see in my room a lot of radio.
I realize this is an old post but I have to say its similar here, I'm a ham and people wonder why radio when you have cell phone. My answer is what will you do if the power goes out? Even as a ham I talk with my friends on a moble CB mon, tue and fri. while watching sports.
Maybe I should change my name to something it has something to do with my name being difficult to pronounce. Maybe I should change it to something like Michael Cardell?
Should probably be fine. There are minor differences in input transductance, input capacitance and gate source voltage but they are so minor I doubt you would notice much in circuit performance difference.
yes I can see how picking up bundles of parts chests and parts radios on ebay makes a lot of sense if you are going to be working on a lot of radios. I just restore old radios so i buy bundles at time myself for parts. Thanks for showing these.
Mike, A pry bar is a necessity ! I work on electronics and HAM radio (even the odd CB rig) and I ended up making myself a small set of these pry-bars out of a set of cheap screw drivers. I have re-capped and cleaned up an old President Madison AM-SSB rig last month. Lovely old radios these are... brings you back to those crazy 80s', doesn't it? Cheers Paddy
LM-300, I haven't seen one of those in 20+ years. I used to work for a cb shop and the owner was always trying to push one on me. He said something about it having a cherry bomb or something in it. I had no clue what he was talking about. I am guessing it was a higher power final. Another radio he bragged about and always tried to get me to buy was the Telestat ssb-140.
Wauuu is a powerfull CB radio (tram second radio), I am not shure but have PLL02A several mods , chasis is similar to midland 79-892 , remember old times with DX contacts, great !!!!!!!!
Kennynva T. Was a mechanic for a long time. Very familiar with what your talking about. I have a couple different ones. I even have one that is kind of like pliers, just work the opposite direction. Squeeze the handles together and the jaws separate. The jaws are basically thin tool steel with a v notch in the end.
I want to ask you a question..off subject...if you break a core to the small transformers, do you flip the core over and it work as new...or replace it entirely? I have a am radio(broadcast band) and broke the core, because of the wax in it..I just want to know if it hurts the alignment in any way...the core was for the oscillating coil.
Kennynva T. In most cases it works just fine. It will effect the Q of the coil because the permeability of the core has changed but usually not enough to be noticeable. Just flip it over and realign that transformer/coil.
Another interesting video as usual, Mike, one question, when you get a radio in and its dirty and grungy, what do you use to clean it.. water, alcohol, acetone... pressure washer.. lol... thanks
+Joe Lees/N3JJL One of Texas Refinery Corp's products. Big Red for most stuff because it's PH neutral and is NSF certified. A few tablespoons full in a spray bottle mixed with distilled water usually gets the job done. For more stubborn grime their TBC concentrate is my next step up. They make from mild PH neutral cleaners to caustic cleaners that will dissolve aluminum. Honestly though, unless it is a real goopy mess just a spray can of ZEP foaming glass cleaner usually does the job.
What I love is eBay sellers selling a used CB for a premium price with no returns, as is condition, in tested. It is basically a gamble with those listings. If it works, cool but I paid a premium for no guarantee and if it doesn't work then your out of all your money for a paper weight. No thank you, if you can't test it or give a return policy then don't expect me to pay retail for your product. What is really stupid is there are idiots throwing away their money buying this stuff anyway.
I have a few ssb radios that I would like to move to 40 meters or other frequencies. Any recommendations on what to change to move the frequency there? One of them is a radio shack TRC 449. I understand I will need to change input and output filtering. Ken
+Kenneth Watson Nothings impossible but that would require redesigning the entire radio. All the RX and TX circuits are tuned circuits in the 11 meter band. They can usually cover 10 and 12 meter but trying to get into the 7MHz range would never work. Also have to think about harmonics. You would need a radio that doesn't have oscillator or mixing frequency harmonics in that band either or you will hear nothing but birdie frequencies.
Yes schematics and service info comes too short on modern radios,dont know who started all this nonsense in CB radio Industry,a lot of engineers can provide feedback to manufactures with bugs,problems and improvements they can address ,thus improving product quality.Its a no brainier! Plus fault finding product,save electronic waste,plus mfrs can still make money on spare parts,service info special tools etc from a official place.When I advise or look at a new radios now,that is the No1 item ,can I get information and schematics,if not for me Mike. Rob 73's
i find all this very interesting i got a royce from a dead family member that is a lot older then me thing is all analog the channel dial is like the old tv's lol i don't want to just plug it in any recommendations on what i should do?
+eddy apple First check the fuse and make sure it is the correct size and the condition of the power cord. Pull the cover and see if it looks original or if it has had a lot of questionable work done to it. Is there anything burned up in it, bare wires, etc... If everything looks OK give it a try.
well looking it over and i gotta say its beautiful all discrete components the one thing thats bugging me and i wanted to ask someone who knows about these things it shouldnt have a 250 volt fuse in it right? it says 13.6 volts on it so that was prolly a dumb question but im trying to learn bit by bit from your videos. it's a royce model I-600B from 1975
Sometimes a junker can be a gem in the rough. I bought an SSB/AM rig years ago with no speaker. Put in a speaker and it worked but had problems with its modulation as well as strong signals causing distortion. Replaced the audio amp and now it works quite good. I now have two Cobra 132's, one of them fresh out of the shop alignment, the other obviously needs serious work inside before I even think of powering it up. Man I love this hobby!
Hi Mike I am new subscriber to your RUclips channel I have a cobra 138 i was wondering you charge to recap and do a alignment and check over to make sure it works as it should let me know thanks
Thank you some of those old knob are really stuck on,also how do you remove the little spanner ring type nuts on the potentiometer. I would like to change those to regular nut type - but do not know what size nuts those old Teaberry radios use,and if a socket will work in the holes.
William Colvin hello from down under in OZ. Find a piece of copper, or stainless or steel tube that comes close to O.D. Of the nut, then file or grind it so it fits the slots in the nut . To get one of first if you don't have one loose try a pair of needle nose pliers, an old set you may have to grind the tips to fit the slots. If it's just a one off job the pliers will do, but if you plan on doing them regularly then the tube is the way to go.
The pliers deal does not work well - not enough room and damages the threads which are already oxidized from age and moisture in the storage area it was in.
+Harb's Elecronics Lab I have to be approaching a thousand working transceivers, receivers, transmitters, stereos and amplifiers with4 or 5 times that in parts chassis.

Watching and learning!

Mike would ytou have an old Uniden Pro650e face? I need one. Assuming you're not doing something different now with life.

@@mikesradiorepair thank you Mike I appreciate you I am a huge fan keep up the good work
Excellent video as usual Mike . You cannot beat parts radios for projects. 73s.
Give you a tip on making covers look good again I used that black spray dip it's rubberized when it dries dries quick 3 simcoach make it look good

Top video Mike, I especially liked the Lafayette. I'm looking forward to more on that I think that's one of the most interesting radios I've seen.
Exellent video. Just picked up a Uniden PC244 without covers any idea of what donor radio's would be compatible?
Had a tram diamond 60 in the late 70 early 80 i think.Damn what good radio.Wish i still had it.
Any progress on a repair video for these three.. Thanks.
Please list your digicom 100 on eBay soon...Thanks Mike !

Hello I have a HAM 2 with Cybernet board and the VCO is broken, in Germany I can not find a spare part :-( where do you get something like that?
Spectrum communications in England makes replacement VCO's. www.spectrumcomms.co.uk/CB_Kits.htm
DO U SALE ANY OF THESES AND IF SO HOW,WHEN AND WHERE. AND 4 HOW MUCH.
Hi Mike I am new subscriber to your RUclips channel I have a cobra 138 i was wondering you charge to recap and do a alignment and check over to make sure it works as it should let me know thanks
Improperly wired /broken connections in the supplied mics might lead to false conclusions. Maybe test the mics before testing the radios...
that tool in your hand lol crooked use it to open cars windows with it mike
Do you ever use that brake spoon to remove stuck knobs?
+William Colvin
I usually use cannon plug pliers for that. They have non marring jaws which help prevent damage to the knob.
Thank you some of those old knob are really stuck on,also how do you remove the little spanner ring type nuts on the potentiometer. I would like to change those to regular nut type - but do not know what size nuts those old Teaberry radios use,and if a socket will work in the holes.
