A walkthrough of the exploration, discovery and repair of the faulty Power Tune application supplied by TIDRADIO for the TD-H3 radio.
To perform this fix follow these steps. This will only work if you're using the same version of the app as me. The one I downloaded was in the "unlocked" download package.
Install some kind of hex editor, I recommend HxD.
Open the hex editor (You may need to run it as administrator)
In the hex editor. open the file "H3µçµ÷.exe" located in the install folder for the Power Tune app.
(Don't be a plank like me and try to open it whilst it's running)
Navigate to offset 0x4853 (hexadecimal)
At this location you should see this sequence:
(If you don't then it's probably a different version to the one I was using)
A3 44 D3 45 00
Replace this sequence with 90's so it reads
90 90 90 90 90
Save the file. Done!

Work of genius. I've been programming for years but never heard of Cheat Engine - looks like it could be really useful in my day job. Thanks so much!
Brilliant demo!!
Super interesting.. A kernel sniffer. Great low level OS skills. Not many know this stuff these days. Well done.
I like this very nice expose of how software works and how to engineer it. may I say `Its a Joe 90 solution'I am also fascinated by the thought of power tuning and what that means.
A lot of "patches" are Joe 90's due to 0x90 being the op-code for NOP. which gets used a lot in such things. From what I can gather, this is just an app to set the power levels of low, mid and high on the different bands. Although the mid level doesn't see to be available on the H3.
@@nicsure Oh fairly basic then I am still waiting for HT to be made with a sd card slot for various applications if they can put one in a £13.00 commercial receiver ie. rektevis FM AM SW one (I love them) shouldn't be too difficult to do it to a HT.
Using a repeater I went 40 miles yesterday and it was flawless. TD-H3 and H8 are the best.
I think if you just set the com port to less than 10 in device manager and in the software it will work. Most of those older programs I’ve used with radios don’t work when the port number is higher.
It’s the power levels it works on my h8 just enter the highest number it will accept on high and you can maximize your output wattage
hello, I have a problem. I have a CRT Micron v2 radio. I need some firmware for this radio. please help
You did not say what version of the app you are using.
Good work
Nice DEMO 👌
Nice job
any new news how do you configure it?
You’re very very good at this! Could you create a custom encryption feature for this radio?
Not sure exactly what you mean. Are you referring to encryption/decryption of audio being transmitted, similar to the "Scramble" feature, but with custom options?
Is there a way to get a Bluetooth headset to connect for speaker and mic functions?
I don't think so, I believe the bluetooth is only for serial data. It's also a little sketchy with regard to reliability. I doubt the code for handling audio would fit in the firmware space, if there's even the ADC circuitry in the radio to convert it and I'm not sure the CPU would be be fast enough either.
What's a Power Tuning Application, though?
It lets you set the high and low power output on the specified bands. 0 being lowest and 255 being highest. The centre column is for mid power level that isn't implemented on the H3 so can be ignored, probably because they reused the H8 software for the H3. There's also the calibration of the VHF and UHF by nudging the offset up or down by steps of 100Hz.
@@nicsure Thank you. So a fairly advanced program that requires you to own some measuring equipment
@@NicksStuff Power meter and frequency counter at minimum, yes.
Can you rename the column headings using hex editor as well? The column names should be "Low power" "Mid power" and "High Power". Actually, the "Mid power" one isn't even applicable to H3 so it can be ignored.
Sure. github.com/nicsure/TD-H3-Engineering/blob/main/pwrtuneheaderfix.jpg
@@nicsure Thanks. Every time I try to save the file with HxD, after modifying it, Windows Defender flags it as a trojan and deletes the file. Don't know how to get around this.
@@pmusic6414 Have you got it installed in the Program Files folder? That might have something to do with it, Windows can get touchy about stuff modifying stuff in there. You could try copying the exe out to another folder, such as the Desktop, modify it there, then copy it back. As a drastic measure you can flag the program's folder in Defender as excluded.
@@nicsure I'm working with a copy of it on my desktop.
@@pmusic6414 I'll upload a zip of the one I modified to Github. See if it causes the same detection. github.com/nicsure/TD-H3-Engineering/blob/main/H3PwrTuneHeaderFix.zip
try entering 11882
When I try to extract the power app I get a virus alert! Anyone else getting that?
Yeah, it's a false positive. But just to stop me looking like some kind of cyber criminal I'm going to have to remove the zip. People will have to hex edit it themselves.
Can you plz send me the zip if that’s fine
The zip is on the GitHub. github.com/nicsure/TD-H3-Engineering/blob/main/H3%C2%B5%C3%A7%C2%B5%C3%B7.zip
It still won’t work for me
Nice work thanks loads M0FXB
