You were fortunate it was only the 5 volt regulator that went open circuit. I was expecting more problems. I see you put a reasonable amount of heat-sink compound on the MOSFET driver IC. Overall a very good restoration... WELL DONE!!! 10/10

[@leonardocristiano7139]

Tôi thích sự phục hồi này, tất nhiên video chỉ nhằm phục hồi thiết bị chứ không phải hiệu chuẩn, mục đích của video đã thành công, cảm ơn bạn rất nhiều.

[@amjadali566]

I love it!!! :) the way he check the voltage regulator with AVO meter, Paint the heat-sink, wash the plastic components and PCB with paint thinner and crank the *walkie-talkie* (VHF Marine) without antenna or dummy load.......... That is superb......... I love a pro job.....

[@TheTheo58]

He did a fine job troubleshooting, after the clean up locating the faulty voltage regulator where there was still no power. Since the power was present at the terminals the fault was further within. Not having an antenna or dummy load connected to the SO-239 connector, when he keyed the mic was a no no.

Appreciate your nicw try..

[@dreamstudiopy6228]

You not conect an vhf antena and not test the output power, that maybe its wrong.... Its a bad idea press the talk butom with out an antena....

[@TheTheo58]

Output power is tested with a watt meter either a stand alone or a combined SWR/RFpower meter with a dummy load on the antenna end. An antenna is needed when testing for SWR when the transceiver is keyed up. In any case not have an independence load connected to the output, can either damage or destroy the final output stage.

I loved this restoration, of course the video has the purpose only in resusceing the equipment and not in calibration, the purpose of the video was successful, thank you very much.

[@leosedf]

Try not to press the PTT when where is no load (antenna) connected, even though it has a vswr resistant module on the output, icom's are notorious for burning output amps.

[@kenzpenz]

Very interesting, I among hundreds of other viewers didn't know that, thanks. Sounded good though, hope Mr E understands this. Enjoyed watching the video, but didn't have a clue what he was doing ;-) .

[@leosedf]

@@kenzpenz All transmitters (of any kind) require a 50Ω load on the output or you usually damage the output transistor. In this case it has an integrated module (it's a tiny ceramic board with a few transistors inside, it's on the back covered by a black plastic) which has higher resistance to burning compared to a simple transistor. However all that power get's consumed in heat form and usually burns even the module or drops it's performance. Most modern ones now have some protection like motorola's but it's more expensive. The bad thing is that those modules are also expensive and many of them hard to find these days.

[@JD-hu9sg]

Ugh here we go again with the don’t press send without an antenna comments

[@glloq75]

Your job is well done but by grace use a real soldering iron, the one that is much too strong for cms component, you will all burn. In addition, you should never use an empty radio, you need a connected antenna, do not forget the SWR that can kill the components of your radio.

[@arielheredia8275]

I think that painting a dissipative surface is a bad idea, since it creates a layer that does not allow the transmission of heat

[@mikebauman7562]

That was not paint, it was heat transfer goo.

[@soupwizard]

@@mikebauman7562 I'd have left the metal behind the thermal paste bare for better heat transfer, and also left bare the contact points on the frame where the board screws into the frame.

[@du1987de]

@@soupwizard What is your reasoning for not using a thermal paste? You wouldn't leave a CPU chip in a PC bare, surefire way to fry the die.

[@talos86]

@@mikebauman7562 then check the video at 7:00. He PAINTED the metal housing and the heat dissipating fins with silver paint. CB radios can be really hot during use, thats why they have those big fins at the back.

[@soupwizard]

@@du1987de Oh no, I'd leave the *paint* off where the the IC joins the heatsink and use thermal paste, just because the paint acts as a bit of insulation. Not much insulation, so it's not a big deal if the paint is there.

You can’t turn it on without an antenna, unless there is some kind of protection there, you can only check for an equivalent load of 50 ohms. There is an assembly at the exit, if it burns, it costs half the cost of this walkie-talkie.

Вот вообще как смотрю видео про эти реставрации электроники, будь то рация, радиоприемник, усилитель, телевизор, смартфон или вентилятор, везде происходит просто косметический ремонт корпуса и чистка от грязи или ржавчины и покраска из баллончика. И нигде не видел собственно ремонта электронной части. . Странно, что эти вещи попадаются всегда исправными. Или же неисправными- тогда их просто не включают. И да, рацию без антенны не включают. Что он там пытался поймать без антенны?

[@andreyl1368]

Я думаю что именно рация . Никогда не заработает после такого ремонта в принципе.... Филтра надо менять То что он помыл это все красота для глаз а не для схемы. Экран не распаял и не глянул что там творится... Да и многое так не моют.. только если поменять половину деталей теперь. и заново все настроить. А шипеть она могла и не исправной.

[@Elfnetdesigns]

he can't use it anyways, when he opened it up he violated any government issued certifications for use on a marine vessel or maritime frequencies. radio is useless in a practical sense now. Not even ham radio operators are allowed to work on non ham equipment that will be used in a non ham band

[@eldermartins3220]

I love this old technology restoration.

[@user-nd3lx1zg9t]

Old technology? That's an up to date marine VHF transceiver. If it was crystalized or had vacuum tubes, then I would concur.

[@UglaAPMMEsplanaden]

• How come he power supplies the unit before checking the fuse first? • What type of solvent is he using to clean the printed circuits with? • Voltage regulators cannot be completely checked like a transistor. They are ICs not single transistors. Besides he already knew that the unit didn’t work initially. Why did he not check the regulator beforehand? • He is testing the Transmitter without antenna or dummy load!!!! The RF hybrid output stage (big black brick in the front of the printed circuit: SC - 1302), usually burns out doing that (max Standing Waves Ratio), and then there is no repair worth the effort. • He tests with his finger for overheated components as the unit does not come alive after sampling. But didn’t he see before dissembling the the that the fuse was OK?. A melted semiconductor would be obvious with a broken fuse. Unless open circuit off cause.

[@shareef010]

Ugla APMMEsplanaden1111 I doubt how he could do that without antenna and how he could connect that part although it’s not the same old one

You need to use a dummy load behind an RF power meter.. Dont transmit without a 50 ohm load on it or you can ruin the final transistors.

[@74Amighista]

Fantastic.

You need a 50 ohm dummy load on the antenna during the PTT or you will wipe out the finals. Your 5V reg needs a heat sink.

[@Subgunman]

Probably let the magic smoke out of the PA. those things can be quite expensive. when one works on ANY 2 way device you need to have a dummy load attached to the radio. first to protect the PA "brick" and second to prevent any stray RF from being transmitted with out identification. It would be nice to explain what you washed the plastics in as well as what solvent you used for cleaning the circuit boards. Also an explanation as to what type of contamination was found (fresh water Lakes and rivers or Salt water) 35 years expeirience working with Commercial, Maritime and Aviation electronics. Seen it all, tried repairing amature mistakes sometimes with success other times not.

Good way to devalidate any government certifications to legally use that radio on a marine vessel.. non professionally trained and certified people are not allowed to repair radios like this, not even ham radio operators You should also never: 1 - Transmit without a dummy load or proper tunes antenna 2. Transmit without a proper license to do so. Antenna or not. In this case a ham radio license is not good enough to transmit on commercial or marine band frequencies either
