Love the diy videos. You are truly contributing to keeping the hobby alive. It’s fun to talk and sound good. But it’s more fun to sound good when I modded it myself. Plz keep showing troubleshooting how toos and mod how toos.
Nice job, I have no receive or trans, PA works. The Cobra 29 Chrome I have has different pcb board that the one your working on. My pcb board has a date of 1-2007 and manufactured in China.
I just bought this exact CB from a pilot. Needless to say I'm not getting anything positive on my radio checks. I calibrated the SWR/ antenna using the radios meter. Maybe that's my first issue. Magnet Mount Wilson lil wil is all I can use on this van.
I peak out my RX chain to a 1Kz injected signal monitored on a scope.Old Skool..maybe someday Ill get one of those super nice universal testers Most every radio I see on my bench has at least one or more detuned RX/TX transformers new from factory.Bad QC anymore!!!
Yea your right about the qc..definitely worth it to go through them and do the proper alignment. I think most new radios bought just get the mod turned up and pushed out the door to save on time. Most people don't understand how long it really takes to do real tune and alignment, I'm sure you can relate. Thanks for stopping by..73
Good day I just picked up a 1985 Cobra 90 LTD meter shows 9 watt dead key external meter shows 2 watts I can t find anything on the net but how to make it louder. Which leads to my main problem keys up but produces no audio out through the meter or on pa. any advise would be great there are no shops that work on radios here.
I have a Cobra 25 WX ST with no modulation and no PA. Do you think that I have the same issue? When I key up, the power needle moves to the left instead to the right and cannot do a cal for my antenna. Also, when I plug in a PA speaker and switch to PA on the CB, I can hear CB chatter like I plugged the speaker into the ext speaker jack and tried speaking and I can barely hear my voice with the dynamike turned all the way up. Do you think there are multiple problems or the same issue that's in your video? How do I send it to you for repair, and what are your rates? Thanks!
Hey I have the same radio. How it has stop transmitting, receiving, and no sound is coming from it. How much does it cost to fix these things. How I send it to you?
Sinad being done by ear? Now that is funny. Yes, like you said you definitely need the proper test gear to get accurate readings in order to verify specifications.
I'm seeing it happen more and more. It goes like this "ok let's check the signal to noise on this reciever, wow that's really good!" No sinad meter in sight..sigh 🙄
What about weak modulation? my volume is up, calibrated but not tuned. Every driver says that they barely hear me and i can't figure it out. It's a stock CB and Mic from Mack Anthem
I have a cobra 29ltd chrome and does not transmit or receive, also when pressing on mic its not putting out power, would replacing those capacitors fix it if so where can I buy them???
Could you tell me what equipment i need to work on cb radio's' ? I have a watt meter,fq counter,vtm. I work on cb radio's it takes a long time to repair some by doing the hard way. Thank you for the Information I just subscribed today !!
@@TheRadioGarage Thank you i had one a long time ago you do good work i subscribe to your channel . I fixed the cobra 29 i check all the volted i found the problem was a bad mic wire on the on output mic gain ...
@@TheRadioGarage It wasn't easy I spend a half day checking voters you help me by your video's & then i found it . I thought everything was right but it had me fooled I've have been repairing since the 80's sometimes the simple things are hard to fix it is not always easy. some new radio's are high tech now days...
@@TheRadioGarage I'm just getting back in radio repair biz after a 20 year plus hiatis .... Wow a lot of things have changed , any chance to get new info from you ????

Where are u getting your scmaticts from great videos
Hey do you install nitro rings behind the knobs? I run at night a lot and it would just be neat to have lol
I’ve got a galaxy 259 the modulation comes and goes any recommended checks?
Brutha ,U make it look EZ , nice job,,,, sent Email to ya.. 73 !!
Thanks, I will have to go through my emails. Sometimes I miss one. 73s

Do you have a website or Facebook page? Looking for more information on what you do and prices of your services.
Where do you go to get your schematics

So did those bad Caps take out the audio chip and transistor or were both of those ok in the end?
The audio chip was actually still ok. Shorted cap was the issue. The caps they use in these newer 29's are very cheap low quality products.
What about weak modulation? my volume is up, calibrated but not tuned. Every driver says that they barely hear me and i can't figure it out. It's a stock CB and Mic from Mack Anthem
You have a coupling capacitor somewhere in the audio circuit chain that is probably going bad.
I have a cobra 29ltd chrome and does not transmit or receive, also when pressing on mic its not putting out power, would replacing those capacitors fix it if so where can I buy them???
Could be a capacitor but could also be numerous other things causing the issue.

Is the xtra bass from the mic or a mod in the radio ??
I opened up the frequency response in the mic plus I made changes in the radio as well. Mostly though the changes in radio are more noticeable.

My radio will not transmit
I have a cobra 29 chrome with no transmit or receive could you help please
I have 2 now that do the same thing.
Check your PLL voltages make sure they are correct.
@@rickyh4796 If you have a FC you can also check for 10.240 at pin 4 of IC3.Could just be a broken solder on the xtal.
@@577buttfan what is a fc?
