Alinco DJ-X11E firmware update tool DJ-X11_ver_2_60E.exe is written with VB6. No need to install, just extract it: msiexec /a DJ-x11_ver_2_60E.msi /qb targetdir=g:\temp\t\djx11\   Detect It Easy strings view shows that there is Motorola S-record data inside .exe I exported extracted strings to file and wrote short Python script for extracting S-record data to file fin = open("G:\\DJ-X11_ver_2_60E.exe.Strings.txt", mode="r", encoding="utf8") fout = open("G:\\DJ-X11_ver_2_60E.exe.txt", mode="w", encoding="utf8") arr = ["S00", "S22", "S20", "S80", "S21"] while True:     line = fin.readline()     if not line:         break     for item in arr:         i = line.find(item)         if i > -1:             fout.write(line[i:])             break fin.close() fout.close() print("done") I asked copilot what is CPU of the Alinco DJ-X11E Answer: ...

Many years ago I wrote a simple SDR# plugin which stores raw RDS hex data in RDS Spy format. I asked Copilot to examine some blocks of raw RDS hex data with prompt: this is RDS data can you decode it?   Copilot asked to verify if it is RDS Spy or Redsea or other format. Copilot decoded raw RDS hex data successfully.    

Visual Studio 2022 dotPeek Alinco EditTool ver.1.00E dotPeek -> Export EditTool.exe to VS solution Form1.cs Form6.cs Change RxModType e.g. to 2 or 3 Modify .csproj file, add line: <LangVersion>12.0</LangVersion> Build and run solution Open the Version form and type e.g. 141421356 on the numpad. ? 

BC125AT_SS.exe can be reverse engineered to Visual Studio solution with dotPeek. It is not necessary to install BC125AT_SS, it can be extracted with msiexec, e.g. msiexec /a setup.msi /qb targetdir=g:\temp\uss\ex Visual Studio 2022 proposes to upgrade the solution to .NET 4.8, it is ok to upgrade it to 4.8. Modify .csproj file, add line: <LangVersion>12.0</LangVersion> otherwise there is err messages: Feature 'primary constructors' is not available in C# 8.0. Please use language version 12.0 or greater #nullable disable is not supported searchserialportform.cs, modify line where str variable is defined, add initilization of str var, string str = "" Many Uniden scanners have quite similar specs (remote protocol, mem organization, modes, etc...). It is possible to change BC125AT_SS to work (to some extent without big mods) with other models by changing the code in where there is a check which model string scanner responds to MDL cmd.   

  https://techcoderadio.blogspot.com/2025/04/bearmock-for-python-3.html Bearmock seems to work better when running in Python 3.14.1 and BC_VUP_V2 with 38400 bps COM speed setting BC125AT scn file decoded with Bearmock: srec_info bc125at-decoded.s19 Format: Motorola S-Record Header: "" Execution Start Address: 00000000 Data:   000000 - 03FFFF BR330T scn file: BC_VUP_V2 showed error: the firmware file is too old for the scanner. After changing the model variable in Bearmock code as UBC3500XLT decoding runs ok. from time import sleep from serial import Serial __MODEL = 'UBC3500XLT' __PORT = 'COM4' __SPEED = 9600 __TIMEOUT = 0  # non-blocking __READ_SLEEP_SECS = 0 __OUT = 'br330t-decoded.s19' ....
