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!

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.

@nicsure 2 ай бұрын

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.

You’re very very good at this! Could you create a custom encryption feature for this radio?

@nicsure Ай бұрын

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?

@nicsure 2 ай бұрын

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.

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

any new news how do you configure it?

What's a Power Tuning Application, though?

@nicsure Ай бұрын

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.

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.

@@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.

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.
