The JTDX v2.2.160 update (specifically the rc7 release candidate) is a significant beta release for the amateur radio digital mode software, primarily focused on supporting new operating modes and improving hardware integration. Key Features and Changes
The most critical addition in version 2.2.160 is the integration of high-demand features from the core WSJT-X codebase:
SuperFox Mode Support: This version adds a decoder for the WSJT-X SuperFox mode, allowing users to work major DXpeditions that utilize this high-efficiency multi-stream protocol.
Hamlib Integration: The update incorporates changes to the Hamlib Transceiver code from WSJT-X. In version 2.2.160-rc7, the software uses shared Hamlib libraries (libhamlib-4.dll on Windows), which allows users to apply library patches or updates without needing to rebuild the entire JTDX application.
Database Updates: The internal callsign database (ALLCALL7.TXT) was updated to the July 2024 version to improve decoding accuracy and station identification. Performance Tuning:
FT8 Decoder: Includes enhancements for decoding efficiency on overcrowded bands.
Resource Management: Some users report that while rc7 has lower CPU load, it may have slightly lower sensitivity compared to previous release candidates like rc3. Availability and Installation
JTDX 2.2.160 is currently distributed as a Release Candidate (RC) and is not yet a stable "General Availability" release. Проблемы с JTDX - Форум QRZ.RU jtdx 22160 upd
Here’s a solid write-up about JTDX version 2.2.160 update:
Do not skip this. Go to Windows Settings > Apps > Installed Apps. Find "JT-DX" and uninstall it. This removes the old executable but typically leaves your user data intact (though we backed it up just in case).
Symptoms: Reports of "Splatter" or "A9" (bad audio) on PSKreporter.
Solution: The update resets the "TX Attenuation" slider in Settings > Audio to 0 dB. Go back and set it to 10-15 dB depending on your interface. Aim for the ALC meter on your radio to show zero movement.
In Settings > Advanced, change the decoding depth from "Normal" to "Deep." Set "Number of decode passes" to 2. This will cause the software to re-scan the audio buffer after the first decode, often pulling out signals at -24 dB that were initially missed.
The JTDX 22160 UPD build occupies a sweet spot for specific operators.
Rating: ★★★★☆ (4/5) – Still a powerhouse for DX hunting, despite being an older codebase.
JTDX 2.2.160 (often referred to as version ) is a major update to the software—a popular, feature-rich fork of The JTDX v2
designed for amateur radio digital modes like FT8, FT4, and JT65. This update has been primarily available as a series of release candidates (RCs), with 2.2.160-rc7
being one of the most widely discussed versions for its performance enhancements and refined user interface. Key Features and Updates in JTDX 2.2.160
The 2.2.160 update focuses on improving the decoding of weak signals in crowded band conditions and streamlining the operator's workflow. Improved Decoding Performance:
Users have noted that JTDX often provides more decodes on modes like FT8 and WSPR compared to standard WSJT-X, particularly in high-noise environments. Optional RX Frequency Messages:
A new functionality allows users to "show messages with my call in RX frequency window." This can be toggled via the
tab and is enabled by default to help operators track their own interactions more easily. Refined QSO Logging: Manual Sequencing Timer:
For manual operations, a new timer cleans up the DX Call and DX Grid windows immediately after a QSO is logged. Improved Time Accuracy: Step 2: Uninstall the Previous Version Do not skip this
The recognition accuracy for "QSO time on/time off" has been improved, and data exchange has been updated to reflect these changes. Smart Sequencing Logic:
The software now better handles non-standard message sequences. For example, if a "CQ" or "grid reply" is answered with a "ROGER+REPORT," JTDX will automatically trigger the appropriate response message. Hamlib Integration: Newer versions like may require an updated
library to ensure proper rig control, especially for newer radios like the Flex 8000 series. The "JTDX Improved" Variant Parallel to the standard release, JTDX Improved
offers alternative GUI layouts, including widescreen and "AL" (alternative layout) versions. It features False Decodes Reduction (FDR)
and additional highlighting for CQ and 73/RR73 messages, making it a favorite for DXers who prefer a more customized visual experience. Community Tools and Extensions To further automate operations, many hams use the JTDX-Helper , a macro-based extension that adds "intelligent" features:
Automatically switches between "CQ" and "S/P" (Search and Pounce) modes. Automatic Frequency Search: Finds free frequencies in CQ mode to avoid interference. DX Chasing:
Can be programmed to prioritize "Wanted" prefixes or DXCC entities. Which software is preferred, JTDX or WSJT X, and why?
JTDX (JT modes for DXing) focuses on maximizing decoding sensitivity and efficiency in both overcrowded and clear band conditions. The v2.2.160 build continues this tradition by integrating several key enhancements: JTDX Improved download | SourceForge.net
