First, I purchased the kit. Then, I found this video. The kit is super easy to understand (except the microchip function) and to assemble. Great soldering practice for beginners. But the result is just WOW. The quality of the sound is amazing. Thanks for the video instruction (especially the SMD one)!
Pin 4 of the iC is FM in. It connects to the earphone socket. The earphone lead is therefore acting as the FM antenna. Experimentation with a separate FM antenna wire somewhere along the path between pin 4 and the earphone socket might be successful.
@@gabrielcayari4745 Look for a datasheet for PHILIPS TDA7088T radio ic or CD9088CB radio ic which I believe are similar to the ic in HX3208 kit. It appears that pin 11 of the ic is related to the FM input signal. I would poke around in that area. HX3208 kit does not have a dedicated FM antenna so the assumption is that the earphone lead acts as an antenna. This is usual in simple, small radios of this type. (This is guesswork as I have no qualification in radio engineering having merely played with many kits).
@@kyrengorkianllo do you know how does the circuit operates? I have one here but I'm just started learning dunno the operation of each components, if its okay to you can you explained to me the circuit operation, where are the pre-amp, modulating, etc. Thanks so much in advanced. I'll send my gmail or whatsapp if its okay
Hi BRUXXUS - Unfortunately in history I can't answer you. You're right xD - strange, gifts have always come to me lately, there were a couple of orders last year in which there was nothing.. I wouldn't know what it could depend on :)
I've received the kit but without earphones. Nevertheless with my Sennheiser HD-470 or with my Apple wired earphones the sound is clear with good stereo image and incredibly balanced bass response. As in all these kind of receivers that use the phones cable as an antenna the reception is somewhat sensitive to the position. But for the price, who cares?
Hello Carlos, it's true it's cheap.. but I'm sorry you haven't been provided with headphones, as it should be! Have you tried to contact ICStation support?
Hello, it was a great video, but I just want to ask if it's possible to directly connect the crystal oscillator either to pin 11 or pin 9 of the IC because when I tried to desolder it, the small copper part came along to the lead that I desoldered, which is one of the holes where the crystal oscillator should be placed. So I just want to ask if it's going to work if I just connect it to pin 11 or pin 9? Thank u!
Hey dude, thanks for the great walkthrough. Mine is powering on, volume controls work, and I can flick between stations, but all I'm hearing is white noise. I think it might be the antenna?
It might, from what you say it's like there's no radio signal. However, double-check the soldering of all components, especially the SMD one, where it's easy to go wrong :)
Hi, the link is in the first lines of the video description, it go directly to the KIT page on ICStation. I just checked now and it works. Let me know if you have any problems!
The main chip uses I2C to get instruction. I donot understand how this circuit is providing I2C instructions without a proper microcontroller. Please help me understand this.
Hi, because that chip is a "SINGLE-CHIP BROADCAST FM RADIO TUNER" - opendevices.ru/wp-content/uploads/2015/10/RDA5807FP.pdf therefore it is an IC designed to act as a radio tuner
@@Stefano91ste well...that is what I thought...perhaps soon I will try to do some experiments about it...any way...thank you for the sharing...🤗🤗🤗👍👍👍🙏🙏🙏

hello I set up an auto scan radio kit hx 3208 I would like to know from which part of the radio I can pull a wire to install an antenna

Nice circuit
Thank you 😎😎😎
Now the "how to solder SMD" video makes a lot more sense. :P
hahaha =)

hi can you please tell me the value of the capacitor 103 and 223 are they in picofarad or nanofarads?
Hack this radio module to tune the stations to run in loop, picking up supposed voices of spirits, make a spirit-box 📻👻😁
Interesting idea :D
Same thing I was looking at doing
Thenks very much.
@2:22That crystal oscillator should have been a few millimeters over to the left. 🤔😆😂👍🏻

Please provide a correct link to purchase the circuit

@@Stefano91ste yes but which frequency to tune and other instructions should be sent via sclk and sdk pins via i2c protocol.
Good idea
Thank you!
Hello, I'm thinking of building the kit. How is the sound quality overall? Either with the supplied phones or other? Thank you
Excellent n my opinion with good stereo separation.
The quality is very high, I was amazed since the circuit does not have an antenna!.. or rather, it uses the headphone wire as an antenna.
Stefano,
hai pensato di stampare una scatola in 3D?
- Si, ma ultimamente ho poco tempo libero.. quindi la realizzerò più avanti!
- Yes, but lately I have little free time.. so I'll make it later!
What if we wanna connect this receiver to the antenna?
Hi, the headphone cable acts as an antenna
@@Stefano91ste what if we want to use a real antenna ( aluminium pipes for example )
It might improve reception in some situations, but to connect that antenna, the PCB would need to be redesigned
@@Stefano91ste well...that is what I thought...perhaps soon I will try to do some experiments about it...any way...thank you for the sharing...🤗🤗🤗👍👍👍🙏🙏🙏
When moving the old channel found radio waves😢
5:43 CRB 😆👍🏻I got punished by Ggle for that.
haha :) not at the moment, probably with about 3 seconds he can't analyze the video
@@Stefano91ste Apparently not even for one second or you will get punished. I dont know how you get away ...
Is it easy to solder?
Yes is easy, in my video you can see all the solder
@@Stefano91ste ☺
