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.
I did not get multiple com ports opening but I still can't get the program to run. Mine always says COM 3. Multiple COM port issues is the cable not the radio. I'm using a FTDI cable.
Great video @nicsure - as somebody else that likes a bit of low-level fiddling and disassembly you've saved me some time! *Wonderful work sir* - Kudos & subbed. I'd like to link this video from my review of the HD3 that's coming up in a few days if you don't mind, saves me re-treading what's already been covered perfectly :)
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 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.
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?
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.
@@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
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.
I used the usb cable that came with my H3! and it brings in numbers that are different then the ones when I start program. Also it works with Chirp possibly they fixed your problem in my release.
odd.. and i do mean VERY ODD !! i have 4850 00 00 00 90 90 90 90 90 8B 44 84 00 6A 00 68 80 .. but a still non working exe file ??? ... any suggestions anyone ???
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.
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!

what HEX editer you using?
HxD
You did not say what version of the app you are using.
Brilliant demo!!

Thank you. No problem
Using a repeater I went 40 miles yesterday and it was flawless. TD-H3 and H8 are the best.
hello, I have a problem. I have a CRT Micron v2 radio. I need some firmware for this radio. please help
any new news how do you configure it?
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.
Another fantastic video Nic! Thanks
Super interesting.. A kernel sniffer. Great low level OS skills. Not many know this stuff these days. Well done.
What's a Power Tuning Application, though?

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

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

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
try entering 11882
Nice DEMO 👌
Good work
Nice !
Nice job
