I really can not understand how anyone can afford to repair one of these CB radios. If it takes 3 or 4 hours to repair these things that is equal to ($75.00/hr.) $225.00 - $300.00 in shop labor time + parts. I guess there must be quite a bit of doing it for "fun" otherwise it is not going to be sustainable as a business model. Perhaps one could get by with a $25.00-$30.00/hr rate in some parts of the country, still $75.00-$120.00 seems like a bad idea to spend on something that could be replaced for $50.00!
These radios cost more than $50 dollars. You can't get an older Galaxy like the 95T2 95T or 93T for under $300 used and that is if you are lucky. Strykers cost $400. new and vintage ones that are not made any more tend to hold their value and if someone is fond of that radio then they get it fixed.
Hi Mike, I’ve been watching long enough to hear you talk about the glue and show examples of it but this was really a great video in my opinion. It really showed the mess this glue cause in just the one small board and how conductive it can be. Thanks a lot for such in-depth explanation of the problem. It sure helps to identify the possible root of a issue.
Mike, How much would a repair like this cost a customer? I would just buy a new radio like a President McKinley. Sounds like they want everyone to do that.
Great channel Mike, that's my name as well lol. I like your laymans term but yet in depth videos. Im learning the tech hobby, and honestly I love strykers. I worked on my 655HP, does well on the meters and a lil showcase of audio at the end of the video. Super clean audio. Please check it out and throw me some pointers if need be sir, criticism is always welcome. 73's
Seems so, it is to make it break later on. I have replaced a couple of the crystals my self. I m not a tech but I can replace caps and obvious parts that need replaced. When you find old radios that dont have hardly any glue they are still working pretty good and then they only need new caps.
Most electronics are designed to have a shelf life. I have a tube radio from 1931 and 1946. One has original tubes and I've recapped and charged the power cords. Most of my radio from the 80's and 90's take so much work to keep running. SMD caps are the worse
I think they did not know how the glue would behave after many years of exposing to fumes, heath, cold, current flow etc. A friend gave me a box of logic ICs. They were stick in anti static black foam. (probably over 20 years old) Some of the foam started to fall apart. The IC's in that foam turned out to be transformed into smd versions (the pins where gone, even from goldplated ICs) The same for the foam in probe and cal kit boxes from brands like HP and Tek. It falls apart and damages the probes. This was not planned. I repair measurement and calibration gear (and some industrial stuff), I have seen 1 case of "roasted" glue in a cnc contoller but I have not measured it before I removed it. It was used to fixate some caps. Nowadays they use the white rubbery stuff (called selastic ? )
You may be onto something..At first Ithought well they used that to hold the parts in process. But clearly the red epoxy under the chips is there for reflow, and yes it can be a real challenge to pop the IC's loose from that Stuff.. So yes why is that conductive glue there !?
Would Isopropanol dissolve the nasty corrosive glue if so would it be a good idea to soak the board in Isopropanol to remove the glue?, make stupid glue illegal to use in electronics?
Isopropanol just bounces off that stuff. About the only thing that will dissolve it is acetone. The problem with acetone is it dissolves any plastic it may come in contact with and there's lot's of plastic in electronics. Used cautiously in small areas it's fine, that's what I do in some cases.
Yup. The old sayings "D.O.A.", "S.N.A.F.U.", "F.U.B.A.R.", "P.O.S.", and other likewise acronyms? Devices like those are what I refer to as "E.F.B.E.R.", which would stand for "Engineered to Fail Beyond Economic Repair."
Hi Mike, 10 minutes in and I see what mean by conspiracy. No need for any of that "glue" on the mpu board. Have you seen any of that "glue" in amateur equipment? 73 WB3BJU
I actually have been making good money off people trying to remove glue on their own.......they usually break legs of components etc and then have to send them in for repair or short legs together with all the pushing and shoving ........the glue on those chips was obviously put on there to create issues......with the chips already glued on there for wave soldering why would more glue be needed after the legs were soldered into the board as well......very very sus

I have a stryker 440 great transmit intermentint well in and out recieve what you thinks went out shorted out

I am with you Mike. They put that crap on those I.C.'s knowing they were already glued down!
I had no idea about the conductive brown glue!
Love this channel. Looking for a good side band i can pick up at pawnshop or flea market

The glue is likely an effort by the manufacturer, to hide the chip identifiers, my best guess !
Although your planned obsolescence is a good one ?

I have repaired so so many radios and hifi with this fucking glue.
It's like the black plague but for electronics. What's really sad is they still use this crap.

Did you say B or D was the CB channel? It sounded like you said B.
D

10 cents worth of glue can often lead to buying a new radio instead of repairing it so they can make more money
Holy cow that is fast! That must be some wicked stuff to kill the radio that quickly! I am thinking China has uped it's game in a bad way! LOL....
