Please select the appropriate version for your operating system. Note: It is recommended to uninstall previous versions before installing this update to ensure a clean configuration.
The jump to v2.2.160 isn't just a minor bug fix; it includes several critical improvements:
Before installing the updated version, back up your configuration. In JTDX, go to File > Open log directory. Copy the JTDX.ini file and your ALL.TXT log. This preserves your station call, grid, and radio settings.

If you're looking to put together an interesting feature for JTDX 22160 or any similar software, here are some ideas that might enhance its functionality or user experience:
For the uninitiated, JTDX is a specialized fork of the original WSJT-X software by Dr. Joe Taylor, K1JT. While WSJT-X is the "standard," JTDX has become the go-to client for competitive DXers because of its superior decoding sensitivity. It often decodes signals that are 1-2 dB weaker than what WSJT-X can see, making it the secret weapon for working stations buried in QRM or QSB.
To truly leverage what 22160 offers:
When putting together a new feature:
Incorporating new features into existing software like JTDX requires a good understanding of the software's current capabilities, user needs, and possibly programming skills. If you're not directly involved in the development, engaging with the development community or forums related to JTDX might be a good way to propose and discuss new features.
JTDX v2.2.160 Update: SuperFox Mode & Enhanced Hamlib Support
The latest release candidate for JTDX, version 2.2.160-rc7, is now available for digital mode enthusiasts. This update focuses on compatibility with modern protocols and improved transceiver control stability. Key Features in v2.2.160
SuperFox Mode: Includes a decoder for the new WSJT-X SuperFox mode, essential for following current DXpedition protocols.
Decoupled Hamlib: This version uses shared Hamlib libraries, allowing users to update libhamlib-4.dll on Windows or the standalone package on Linux without needing to reinstall JTDX entirely.
AutoAGC Improvements: Reworked mathematics for autoAGC, including SNR and noise value tracking for every interval, providing better performance via TCI and supported Hamlib radios.
Database Updates: Includes the ALLCALL7.TXT update (as of late 2024) and optimized GRID square/US State databases. jtdx 22160 download updated
UI Tweaks: Displays time offset directly on the Sync button and offers new tooltips for Tx, Sync, and AGCc buttons. Download and Installation
Official stable releases are typically hosted on the JTDX SourceForge page. However, as v2.2.160 is currently a Release Candidate (RC), it may be found in subdirectories or distributed through community groups:
Windows (64-bit/32-bit): Look for jtdx-2.2.160-rc7 installers on SourceForge or the JTDX FreeForums.
JTDX Improved: For a modified GUI with extra features like band hopping and better highlighting, check JTDX Improved on SourceForge.
Note for Linux users: You must install the standalone Hamlib package before installing JTDX v2.2.160 to ensure the shared libraries function correctly.

The release of JTDX v2.2.160 (specifically the General Availability "GA" and late Release Candidate "RC" versions) represents a critical milestone in the evolution of digital mode software for amateur radio. As a highly specialized fork of WSJT-X, JTDX (JT modes for DXing) has carved out a niche by prioritizing decoding efficiency and sensitivity in the most challenging high-frequency (HF) band conditions. Technical Evolution and Key Features Please select the appropriate version for your operating
JTDX 2.2.160 introduced several significant updates designed to streamline the operator experience and improve performance on overcrowded bands like 20m FT8:
SuperFox Mode Integration: One of the most vital additions in the rc7 build was the WSJT-X SuperFox mode decoder, allowing JTDX users to participate in modern high-traffic DXpedition environments.
Hamlib Decoupling: On Windows and Linux, the software transitioned to using shared Hamlib libraries (.dll or standalone packages). This allows operators to apply critical Hamlib patches for new transceivers—such as the FLEX-8000 series—without needing a full JTDX rebuild.
Enhanced FT8 Decoding: The update implemented candidate list thinning for slower CPUs and DT weighting, which improved overall decoding efficiency. It also removed the "fast/medium/deep" options, defaulting the decoder to its most powerful "deep" mode.
Automation and Safety: JTDX continues to excel in "Wait to Call" features and automatic TX halting. For instance, it can turn off transmission if the target station responds to someone else, preventing unnecessary "ether spamming". Community Impact and Availability
The development of version 2.2.160 has been marked by both technical progress and external geopolitical influences. For a period, official public releases were halted due to the developer's stance on international issues, leading some users to rely on beta distributions or community-led forks.
Despite these hurdles, JTDX remains a preferred tool for many because it consistently decodes more signals in crowded bands than its predecessor. For those seeking additional UI customizations or specialized features not in the standard build, JTDX Improved offers an alternative version based on the same core logic. Summary of Major Build Changes (v2.2.160-rc7) Improvement Detail Decoder Added SuperFox mode support and updated FT8 thinning logic. Databases Updated ALLCALL7.TXT and US State/GRID square databases.

For crowded bands (e.g., 40m FT8), use Settings → Audio → Passband from 200–3000 Hz. This rejects out-of-band interference.
