The 2.2.160 update focuses on audio flexibility, hardware compatibility, and rigorous operator attendance requirements:
TCI Audio Enhancements: In 2.2.160-rc8, developers added the ability to select a 12000 sampling rate and new integer formats (two-byte for 16-bit builds, three-byte for 32-bit builds) instead of the standard four-byte float format.
Shared Hamlib Libraries: Recent builds (such as rc8) utilize shared Hamlib libraries. This allows users on Windows and Linux to apply Hamlib patches by simply replacing a .dll file (like libhamlib-4.dll) without needing to rebuild the entire JTDX application.
Operator Attendance Check: A notable behavioral change in versions like rc7 is a "five-call limit." If an operator does not interact with the program, JTDX may automatically turn off or enter a standby mode after five calls to ensure the operator remains present at the station.
Superfox Mode Support: Version 2.2.160 (specifically rc7 and later) includes support for the Superfox mode for Hounds, a feature critical for modern DXpedition tracking. Release and Availability Status
The distribution of 2.2.160 has been unconventional compared to the stable 2.2.159 release:
Closed Beta Testing: Many early 2.2.160 release candidates (such as rc7) were initially distributed to closed groups of beta testers rather than the general public.
Public Release Delays: There has been public controversy and conflicting information regarding the release schedule. While some SourceForge listings show 2.2.160 files as of 2024–2026, original developer statements in 2023 indicated a halt on public releases due to the ongoing conflict in Ukraine.
Derivative Versions: Due to the slow official release cycle, many users have migrated to JTDX_improved, which implements similar features—like enhanced Dark Mode and band hopping—while maintaining a more frequent update schedule. Version History Summary Notable Change 2.2.160-rc3/4
Introduced "Fake It" setting visibility changes and bug fixes for 32-bit builds. 2.2.160-rc7
Added Superfox support and the 5-call operator attendance timeout. 2.2.160-rc8
Added 12000 sampling rate for TCI and shared Hamlib library support. JTDX v2.2.160
The history of JTDX v2.2.160 is marked by a significant period of delay and community controversy tied to the geopolitical conflict in Ukraine.
While JTDX is a popular piece of amateur radio software used for digital modes like FT8, the release of this specific version became a point of contention among users. Key Developments Release Context jtdx 22160 upd
: JTDX v2.2.160 followed a long period without public updates. Discussion within the community suggested that the developers intended to halt public releases until specific geopolitical conditions were met—specifically, some interpretations of public statements indicated that no new releases would occur until the Russian military presence in Ukraine ended. Community Debate
: The developer's stance led to heated debates on public forums like the JTDX FreeForums
. Some users misinterpreted early statements as a sign of support for a particular side, while others argued that amateur radio and its software development should remain apolitical. The "Story" of the Update
: The narrative surrounding this version is less about technical features and more about the intersection of global events and software maintenance. The release eventually moved forward as a way to provide the community with necessary bug fixes and performance improvements after the extended hiatus. for this version or how to install it on your operating system? JTDX v2.2.160
Users of the previous 2.2.159 build reported that automatically spotting stations to a local DX Cluster via UDP would sometimes duplicate spots. The jtdx 22160 upd resolves this by adding a debounce timer to the UDP spot generator.
Q: Is jtdx 22160 upd compatible with JTDX on Linux (Ubuntu/Debian)?
A: Yes. Binaries are available via flatpak or manual build from source. The command line update process would be: git pull from the source directory, then mkdir build && cd build && cmake .. && make -j$(nproc).
Q: Can I still run WSJT-X alongside jtdx 22160 upd? A: Yes, but not at the same time using the same radio. You can install them in different directories. Do not share the same logbook file between both apps.
Q: Does this update support Super Fox mode for the upcoming DXpedition?
A: Yes. Version 2.2.160 includes the full Super Fox (SF) decoder. Ensure "Enable Super Fox mode" is checked in Settings > Advanced.
Enhanced FT8 Decoding
The core decoding engine has received tweaks that improve sensitivity in noisy band conditions. Users are reporting slightly deeper decodes (down to -24 dB or better) without a noticeable increase in false positives.
Improved Waterfall & Audio Handling
Latency issues when switching bands or audio devices have been reduced. The waterfall rendering is smoother, especially on mid-range hardware, making it easier to spot faint signals.
Rig Control Stability
CAT control via Hamlib has been updated, resolving intermittent dropouts reported with certain Icom and Yaesu transceivers in previous builds.
Better Contest Logging Integration
ADIF export now includes more consistent support for contest-specific fields (e.g., STX_STRING, SRX_STRING), simplifying uploads to Logbook of The World and major contest robots.
Minor UI Polish
The Band Hopping and Auto Seq functions are more intuitive, with clearer tooltips and status indicators. JTDX is a software tool often used by
Absolutely.
If you are serious about FT8 contesting, chasing DXCC on the low bands, or simply want the most responsive digital mode client available, the jtdx 22160 upd is mandatory. It fixes the nagging UDP and CPU bugs of the previous spring builds while introducing no major breaking changes.
The update process is straightforward if you follow the backup and clean install method. While some users have reported minor audio device resets, the trade-off is a dramatically more stable decoding engine and better CAT control.

The JTDX v2.2.160 update represents a significant leap for the popular ham radio digital mode software, primarily known for its high-performance FT8 and FT4 decoding. While versions prior to this release were considered stable, the 2.2.160 series (including various Release Candidates like rc7 and rc10) introduces critical compatibility updates for modern DXing. Key Features and Improvements
SuperFox Mode Support: One of the most vital additions in the 2.2.160 update is the SuperFox mode decoder. This allows JTDX users to participate in high-volume DXpeditions that utilize the newer WSJT-X SuperFox protocol, ensuring you don't miss out on rare entities using this high-efficiency mode.
Updated Hamlib Integration: The update includes significant changes to the Hamlib Transceiver code. Version 2.2.160-rc10, for instance, uses Hamlib 5, which improves rig control stability and expands support for newer transceivers.
Enhanced Grid Validation: The software now better validates the last grid from sources when the size is the same, reducing erroneous entries in your logs.
Database Updates: The internal ALLCALL7.TXT database has been refreshed (as of mid-2024 in earlier RCs), providing more accurate callsign and name lookups during decoding.
UI and Language Refinements: Users will notice updated translations and minor GUI fixes, such as resolving buffer overflows on very large screens. Important Operational Notes
DXpedition Messages: In the latest builds, DXpedition special messages are not supported in autologging mode. If you enable "Auto Log," the DXpedition message options will be automatically blocked to prevent configuration conflicts.
Installation Strategy: On Windows and Linux, recent builds utilize shared Hamlib libraries. This allows users to apply Hamlib patches or update the libhamlib-4.dll file independently without needing a full JTDX rebuild. uses Hamlib 5
Experimental "Improved" Versions: For those looking for further UI tweaks (like the "Band Hopping" button or AL-style layouts), community-maintained versions like JTDX Improved by DG2YCB build upon these official updates. Download and Availability
Official releases and Release Candidates are typically distributed through community hubs like the JTDX SourceForge page or dedicated ham radio forums. Be sure to use the password "jtdx" if downloading protected zip archives from developer-supported threads.
Pro-tip: If you are chasing a specific DXpedition, ensure you are running at least rc10 build 3 to benefit from the latest autoselection fixes for special DX messages.
