Open your .bat startup scripts in Notepad. Ensure the paths point exactly to your new folder location. Summary Troubleshooting Checklist Did you download the base 1.101 files first? Did you overwrite the base files with the update files? Are your DLLs 32-bit (x86)?
The first time you run FMPA, it will benchmark your CPU. Do not run other intensive programs during this process. 2. Update to the Latest "Base Files"
Resolution of Connection Failures and Source Unavailability in DSDPlus v271 Download Infrastructure
A: Yes, but the 271 download fix is different. Use winetricks to install vcrun2022 and corefonts . The error 271 on Linux is almost always a missing libusb or permission issue on the raw audio device.
Once you've completed the above steps, attempt to download DSD+ 271 using the verified link. If you're using a download manager, make sure to configure it correctly.
Instead of showing a valid frequency (e.g., 450.025000 ), the display may show 271.000000 or simply 271 . This effectively breaks the frequency tracking, making it impossible to follow trunked radio systems correctly.
To prevent Windows from deleting your files during extraction: Create a new folder named C:\DSDPlus .
Instead of double-clicking the icon, create a .bat (batch) file in the folder. Right-click > New > Text Document. Type DSDPlus -i1 -o1 (adjusting numbers for your specific audio devices) and save it as start.bat . Running the software this way allows you to see error logs if the program crashes. To help you get this running correctly, could you tell me: What specific error message are you seeing?
Assuming a user has obtained a legitimate package, several technical issues can corrupt the download or prevent the software from running. The first culprit is . DSD+ 2.71 is typically distributed as a ZIP or RAR file. If the download is interrupted due to an unstable internet connection, the archive may be incomplete. The fix is simple: verify the file size against the official source and re-download, preferably using a download manager that supports resuming. The second issue is overzealous antivirus software . Because DSD+ interacts directly with system audio drivers and uses DLL injection for SDR dongles (like RTL-SDR), many antivirus engines flag its executables ( dsdplus.exe , fmp24.exe ) as false positives. The fix involves temporarily disabling real-time scanning, downloading the file to an excluded folder (e.g., C:\SDR\DSDplus ), and adding that folder to the antivirus whitelist before extracting.
Instead of using the 1R.bat script, manually run:
A: No. Version 2.271 is strictly "Fast Lane" (paid). The free public version remains at 1.101. If you found a "free 271 download" on a blog, it likely contains malware or the error you are trying to fix.
If receiving checksum or missing DLL errors, download the required base files (e.g., FMP24.exe, DSDPlus.dll) mentioned in the 2.71 release notes and move all of them into your main DSD+ directory.
DSDPlus (Digital Speech Decoder Plus) is a sophisticated Win32 application that reliably decodes multiple types of digital audio formats commonly found on VHF, UHF, and 800 MHz bands. Version 2.71 is an update meant to be applied to an existing installation of DSD+ 1.101 or higher. In fact, the developers explicitly instruct users to copy the DSD+ 2.71 files into an existing DSD+ 1.101 or higher folder.
: Native Windows zip extractors often fail to prompt for the password required for Fast Lane updates. Use 7-Zip or WinRAR to extract the files using your assigned update password. 2. Missing DLL Fixes
To avoid permission issues or file conflicts, do not overwrite old public versions (like 1.101) directly with 2.71 files unless specified in the notes. DSDPlus – Digital Decoder
To help narrow down any remaining configuration issues, tell me: What are you pairing with DSDPlus?
How to Fix DSDPlus v2.271 Download and Setup Issues DSDPlus is the gold standard for decoding digital radio protocols like DMR, P25, and NXDN using cheap RTL-SDR dongles. However, many users tracking down the run into broken links, missing DLL files, or execution errors.
