- Mindless soldering of random electronics kits to some classical music. If you're watching this, I'm sure your day couldn't possibly get any more exciting than this...
This kit was from China/eBay. It was $8.45, and shipping was free.
I will probably get another radio kit, only with a digital tuner, in the near future. That will be more useful for FM tx/rx projects than this crappy analog one.

Hakko FX888D Soldering Station: amzn.to/2Wh72CU
Lead free solder: amzn.to/2WdnZOJ
Flux Pen: amzn.to/2Mx49Ju
Panavice junior: amzn.to/2WgNIFT
Good and cheap side cutters: amzn.to/2B1LyRE

Of course I get this video reccomended, 4 hours after I completed this god forsaken Kit...
Man, I started all of this from 0, and it's a whole month going now💀😭😭
In a world where the TV portion is 100% useless... Anyways Shango066 has better videos on building these cheap kits and he explains step by step what to do. It's worth a look at least.
Many thanks for the video. I have just put one together myself and would not have managed it without your video.
so helpful, this kit arrived today, with only chinese instructions, this video will be a real help in assembling it. thanks
Hola. La armé, pero se escucha muy bajo y en FM no capital emisoras. Me podràs ayudar para saber donde puede estar el fallo?
I AM ROCK HARD
I got this kit, and I wish I saw your video instead of another guy's. The problem with my kit is that the resistors and the capacitors have their colors/numbers so worn that I could barely make out what they were. I hope I got them in the right positions.
Great video, just built mine and it's up and working....had to spread the coil to get FM. Your video made things much easier, Tnx Much!
Good video managed to complete, only 5 stations though but great practice kit !!!
Muito bom ; paciência máxima.
I bought a similar radio from online but it is not receiving FM. It would be helpful if you could tell me how to receive FM.
Just go to the doctors he will give you a prescription for fm tablets you total waste of time
Awsome video! KKEP PARTS IN A BREAD BOARD. MUCH EASIER TO MANAGE.
I use a USB microscope. Much easier on the SMD.
hi there,thanks for your video. i really appreciate the effort of uploading it. i watched your video and tried to assemble as my best, when i put batteries in it didn't worked. i am not sure whether i have done correctly or not. could u plz upload slow version of this video where we can see how u measure the capacitors and resistors to insert clearly. thx kindly
Thanks for the video. I yet don't worked with my kit.
We grew up on classical music!
My radio works but I have no signal can you help me please?
How can it work then ?
i enjoyed the music as much as the vidio
I managed the soldering of the 9088 IC more easily than I thought, with the aid of some tweezers and a magnifying glass on a stand. The flux pen is a good idea too.
I have only just made a start with the wiring. I have got a bad head cold at the moment, which does not help concentration in a heated room. The speaker is wafer-thin, literally
I just wish there was some room to fit something that'd have a little better bass.
For a UK price of less than five pounds you can't really complain about the quality of the parts provided.
Nice! Glad to hear you got it sorted out
My FM doesnt receive anything
Parabéns. Foi muito instrutivo. Agora mãos a obra.
By separating the turns of L2 like a bed spring I have managed to get stations.
They are not quite in the right place. I don't know what the effect would be if you did the same with L1.
I would like to sharpen the tuning of the AM side of the radio, if that is actually possible.
Does adjusting the trimmers on the tuning capacitor affect the FM tuning. If 'yes': In what way?
I can't believe that nobody has put up a documented build of one of these kits & the proper adjustment routine.
Yes. I had to go back and forth w/the small coil spacing and the tuning cap trimmer to get FM band spread "kinda" right. AFA the AM trim cap, in my location, had no useful effect (I did not "cheat" and use a RF generator to try and calibrate either AM or FM.) You'd have to fiddle with the ferrite loop stick to correct AM bandspread calibration (the "large" coil would have no effect.) Remember this is a *single* RF stage/tuning design so you don't really get to "sharpen" ANYTHING, strongest local signal wins, period.
The trimmers on the tuning capacitors affect the calibration towards the high end of the tuning dial.
Monolithic radio IC: SMD package.
Amplifier IC: DIP package.
Just assembled this kit but FM doesn't work at all, just hissing. AM works fine. Can anyone tell me what the problem might be?
SIR AISON FROM PH
I find the resistors are usually fine, but I checked the ceramic capacitors used in the FM section. Just in case the values are not right.
Built one myself, going to have to get a flux pen. Thought I'd cooked the SMD chip with my hot air gun. Turns out it was just the speaker soldered to the wrong part as show in a different video. Thanks👍
I failed.
Có sơ đồ có đủ linh kiện thì việc rắp ráp rất đơn giản
how many volts did you apply for testing?
22098 volts
200000 v
then it was your flux pen. In the brief flash we got of it it looked like one of those large whiteboard markers. At first I couldn't tell exactly what it was. You made a neat job of the 9088 IC in any event. I don't want to make a hash of the kit I get.
Still need to adjust the coil cause there was no IF x'former....also the Tuning capacitor adjust it or align it..
Just finished building mine. AM kind of works, FM is completely dead. Not even white noise.
Goood
Hi! I'm new in soldering, so I wonder what is that yellow marker you're drawing with in 5:21? Is it compulsory to use?
It's a flux pen. Not compulsory, but *very* handy.
Boa tarde gostaria de comprar um kit desse onde encontro

How “sensitive” is the receiver? .. is it strong for stations only, or is it a good rx?
Not very sensitive or selective. That requires either a super-heterodyne, super-regenerative, or reflex regenerative receiver. The TA7642 is a basic TRF, which can be modded to become a reflex regenerative receiver if the circuit permits, but is not so with this kit circuit layout, which cannot be modded, and doesn't even have close-tolerance (1% or closer) components required for this type of thing, meaning that it will be a matter of luck if it works at all well, quite apart from the fact that components are jammed up against each other in such a small space instead of being well spread out like in British or American kits, and components being so utterly close to each other is potentially very bad design. It isn't any good at all beyond about 1MHz with this setup, and very unselective even at the lower frequencies if you live in an area within about ten miles of a very high power MW jtransmitter, which is true in my case. FM just gives a hiss unless you live across the road from the FM transmitter, and I don't.
hola acabo de montar la radio pero solo escucho AM. Y fM no recibo. ¿cual puede ser la causa?gracias
Hi. Got this kit, and it was literally smashed. The only thing that survived was the speaker, resistors and IF cans. Oh well, I'm going to order a couple more. should be able to make one good one out of 3.!! LOL..
Why this information ?
The tuning dial theatrics were amusing.
Super ! j'ai construit le même et il fonctionne très bien, et vu le prix !!
What is the alignment procedure?
Someone else who has done one of these radios advocated putting L2 on the print side of the board to make adjustment easier. Something to do with spacing the turns of the coil out a little.
I have done two of these radios & unfortunately I have come to the conclusion that they are a piece of dung. The AM side is particularly bad.
For what you pay it is no surprise. It is a disappointment after the effort of construction.
I have modified this radio to also receive SW band.
Very easy.
How did you do it?
Adding some coils and capacitors... cant explain it in english 👍😊
When you were soldering the FM chip on the circuit board: Was that liquid flux?
All I have is the Bakers rosin flux in a tin. I am wondering if wiping the pads over with a tissue smeared with flux would work.
I think I can get a needle tip for my soldering-iron too.
It seems like the soldering of the CD9088 FM chip is possibly why misigun's radio only works on AM.
I have bought one of these kits and I am wondering about the best & safest way of soldering the 9088 chip in as it is a surface-mount type. I am surprised that the chip does not come in a variant where a socket can be utilised as with the audio IC.
The AM section is simply a TA7642 IC, a clone of the Ferranti ZN414.
+NJPurling If it was an SMD part, it was solder paste. If it wasn't, then it could have been my flux pen to ensure a good clean solder flow. Both are very handy to have.
The SMD stuff isn't too hard to solder. Just make sure you clean the pads with flux or some type (even if you have flux-core solder) Just get a tiny bit of solder on your iron tip, then "tack" solder one corner pin, then you should be able to get a medium amount of solder on the iron tip, then wipe it across the pins on the other side. The solder mask should prevent solder bridges between pins. (if it does bridge, just wipe the iron across the pins again. If that doesn't work, use solder braid to remove excess solder and try again.
listen to an am radio while you solder the 9088. pge has grounded the high voltage. odd megavolt pulses. 24000 volt soldering iron
A Chinese rip off of Panasonic! 😂
Kinda disconcerting. 🙃 Seems like they could get sued. The TM doesn’t quite look right but they try.
does tv station works?
how much,where to buy,etc.
+Ron Thompson Nobody ever reads the video description lol. It was from ebay and it was $8.45 from china.
Thanks
Thanks
No problem
Amazing....
👍👍😋😋😋

I love soldering as well but hate the lead free solder, that sucks.
Lead free is the work of people who don’t solder ! Terrible for electronics
Buy lead free that doesn’t suck
Nice music & video
Qual o preço
I enjoyed your video. Is there some reason you didn't put in the resistors first?
No reason that I can remember
In certain countries it’s against the law to put the resistors in first you moron.
Ótimo um verdadeiro passo a passo
Music ?
Can you tell me the kind of soldering iron you are using? Model and cost if you can...
It is very expensive but it is an excellent soldering iron.

Thanks so much for your prompt replied. It looks good and so perfect for small spaces. BTW, like the background music!!! Keep it coming.. 73, Joe-k4jga
You need a massive plumbers blow torch you moron
Lol
just no
Oí
mine is not working, only AM works
adjust 8t up - check a few parts
cool radio!
Hook up your frequency counter to tune it to 108MHz and that is all that you can do. My kit came with resistors so small that I need a stereoscope to read the colors. This little guy is quite a challenge. Nice job on the SMD chip.

Chinese factory workers have to make five of these per hour, for literally no money and they're grateful for it. That's how much fun soldering is! No wonder they charge 3 times the price for the kit, than the fully assembled product. I love soldering!
Excelente vídeo.
Marcos R obrigado!
Without FI, FM oscillator? Where is the audio transformer for the speaker?
🤔🤔🤔🤔
@12QWASZXQWERTYUIOP
Ok my friend. Thanks a lot for helping.👍👍👏👏
its not charlie chaplin movie , show us number by number , which wire what .
Slower would have been more useful and the music is just annoying
🤔if you don't like the music turn down the volume & slow the TH-cam speed down a tad
Maybe try Tampax when your menstrual starts to flow?....
@@urbbs09 lol
I have finished the radio: FM works, sort of. How do you set the tuning for FM?, so you actually get FM stations about where they should be?
It is tuning something, but no music or talk stations yet. I assume that you have to do something to those little copper coils, but won't do anything until I hear from you.
AM is OK.
The set gave sound, after I switched one speaker wire. A few people have made that mistake.
I wish there was a site with build instructions in English plus alignment advice.
The same adjustment dial is used for both AM and FM. I literally just assembled it and it worked without having to adjust or tune anything
Panasonic ??
No.
