- Опубліковано 8 лип 2024
- We had a viewer ask about what microprocessor was in the TD-H8. So we opened one up to look inside.
This is what we found:
RF Transistors: HTL7G06S011P - 100-600Mhz 11Watt 7.2 Amp
2904 Op Amp
AT 1846S Radio on a Chip
HK 24C64 I2C EEPROM
TDA2822G Audio Amp
TLSR8261 Bluetooth BLE SoC
BEKEN BK1080 - 65-108Mhz FM Receiver
TA3782F Microprocessor (Let us know if you know what this is!)

Excellent video! Keep'em coming! Also like the organization of your video summary!
Thank you for the comment. I'll do my best! 73s
Excellent tear down! great video!
Thank you!! Very happy to have you here. Thanks for watching and dropping a comment! 73s
Very interesting type of video. Please keep them coming.
You got it! Thanks for watching!!
Well done, thank you!
Thank you too! :)
Teardown videos are very useful. Thx.
Thank you, glad you like them too. :)
Thanks!

I went back and rewatched your video of the tear down on the Baofeng UV-17; UV-17R; UV-21Pro; Radiodity GC5 and I noticed the speaker and front buttons from your previous video were all connected with a ribbon cable, BUT this Tidradio used a 2 conductor wire soldered directly to the main board for connecting the speaker ??? What a pain for reassembly !
I would much rather buy a brand that used ribbon cable for its connections even if the price was significantly higher. Thanks for doing the teardown. It’s nice to be able to see the differences of the various brands on the inside
Thanks for the comment. Yes it is interesting to see how they vary. Some have nice plug-in connectors and some are soldered to the board.
I much prefer wires over ribbon cables. Easy to repair and tend to be more robust. Typically adds no extra pain during re assembly. Shouldn't be disassembling unless you have the adequate tools anyways.
These cheap radio manufacturers count pennies with recurring costs. (BOM & labor). Repairability doesn’t even enter into the equation. Everything is about driving the cost down and getting the reliability to perform past the warranty period.

The TA3782F is an integrated circuit (IC) manufactured by Toshiba Semiconductor. It is specifically described as an AM/FM 1CHIP TUNER SYSTEM IC
Interesting! Where did you find this information? I tried searching again, and can't find this online anywhere. :( The only site that I can find a mention of it is a Russian site in a radtel radio.
Interesting what it looks like inside.I have a green version of this radio.Its a great radio.Only problem I have,is,its not water resistant.Oh well.Maybe it will happen one day.Got great reports from this radio.Great video!
Thank you for watching! I agree water proof/resistance would be great!
Great info thank you!! When will the new TD-H8 Plus, or whatever they call the upgrade, be available?
Not sure yet, I haven’t heard anything from them. Thanks for watching!! 73s
Just one question, are there quick mods for the device because the key combination doesn't really work in Open, the part is still in the old state 🥴
As far as I could find, the TA3782 is a McKinney steel half mortis hinge with bearings - "Half Mort/Hvy Wt/Brg/5K 1 TA3782 Steel". Though I will hinge a bet that is it a proprietary FPGA of sorts.
LOL! Yes, the HINGE, why didn't I see that! :) Thank you for watching and commenting!! 73s
@@KC4NWK Thank you, I enjoy your vids.
I'm not 100% but the controller seems to be a variant of the AT32F421C8T7 or similar, maybe even just rebadged. Investigation in ongoing.
Thank you, keep us posted!!! I'm about ready to post a video on the TD-H3 insides... and it has the same CPU. I know people were wondering about custom firmware for these radios like the Quansheng UV-K5(6)! The TD-H3 has the same radio chip as the Quansheng, but with a mystery microprocessor, the hacking becomes a little more difficult. Thank you for watching and commenting! 73s
@@KC4NWK Upon further digging I think I'm totally wrong. I couldn't get anything to make sense given the firmware image for the H3 when assuming it was an ARM Cortex core. The core that seems to produce the best and more consistent disassembly is the Intel 8051 MCU architecture.
@@nicsure That STM32 is an Arm Cortex M4 part - I honestly can't see them using an MCU like that as a controller in a low cost device like this, especially since all it has to do is run the keypad and display and send a few commands over I2C. Using some 805x derivative seems a lot more plausible. Finding out which one could be a challenge though - there are a huge number of 805x core MCUs on the Chinese market with a wide range of different features and capabilities, and most of them don't even have an English datasheet available.
@@TrimeshSZ It's an 8051 variant.
Ah damm it. CPU is probably one of baofeng clones mystery ones. THX for teardown.
Yeah I was hoping for something a little more main stream as well. We'll have to see what is inside the TD-H3 when I get one. 73s
It would have been nice to find a well documented microprocessor: possibly then, the firmware could have been modified (just like with the UV K5). 😢
Exactly, I'm not sure the AT 1846S is as versatile as the BK4819, but some tweaks might have been possible! Thanks for watching and commenting! 73s
BTW, thanks for the teardown! I'm always concerned about breaking the brittle LCD display, which I am sure is either hard to find or impossible to replace without special tools... I'm glad you took that risk for me / us. 73's from F4LBH
Might see if I can desolder it and put in my programmer and see if it can auto detect the chip
Searched chip can't find datasheet asked chatgpt it says its a Toshiba PLL frequency synthesizer ic I'm talking about the ta3782f looks like chip is tqfp48 I'll have to wait on socket adapter to zif
If you do, please be sure to come back and let us know what you find! Thanks!
So I wonder if this can handle custom firmware.
Cool
;-)
How would they go about reducing spurious emissions? Are there better components that would be used? Or better insulating materials? I am curious what they changed to meet the standards
That's a great question. It is possible to use better components, or even changing certain values of components in the filtering circuits. I haven't looked side by side at the boards, but there is also possibilities of board revisions to include more filtering.
Another brilliant video!!!! Just out of interest, could you please strip down Baofeng Uv18 promax GPS 10Watt version when you can, please?
Thank you so much. If I get my hands on one we can do that. Thanks for watching and commenting! 73s
@@KC4NWK pleasure as always! Excellent videos you produce!
Dream Radio
Thanks for commenting! The newer TD-H8 radios that are clean are nice radios for the price.
@@KC4NWK They Sure Are, But Still Unreachable For Many .
What are you using for a microscope?
The microscope that I use is an AmScope SM-4TPZ link: amzn.to/3TJlCTB or amzn.to/49Q1fcR This is the camera that I'm currently using on the scope: amzn.to/3Tqm47H 73s!
Please comment on the long bow on the wall.
Ricky from IBM K4VMS
:) That is a Mathews Heritage longbow. This was during the time that Mathews Archery owned Sky Archery (originally Earl Hoyt's company) and was making traditional bows. The one you see is signed by Matt McPherson. There is a Mathews Heritage Eagle recurve on the other wall (also signed) out of frame in the video. Thank you for commenting!! 73
Out of all the radios I have, the TD-H8 has the worst fm broadcast receiver. Broadcast channels I receive on all other radios are nothing but noise on the TD-h8. Unfortunate because I like everything else about the radio, but the poor 65-108mhz reception kills it for me. Seeing the beken chip that is to blame was interesting.
This just goes to show how different people will value different things. When I hear that the rx is deaf there, I think that is a good thing because it should reduce intermod from those strong signals.
Great video! Professional quality, and a really cool look into the radio. 73 de KN4EDG
Thank you very much! It is fun to see what is inside some of these handheld radios. I've got a couple more coming up! Appreciate the view and comment! 73s
