One of the most anticipated "new" aspects is experimental multicore support. On older versions, decoding 15 seconds of FT8 used a single CPU thread. In version 2.2.160, you can enable Settings > Advanced > Multi-threaded Decode. On an 8-core processor, users report decode times dropping from 0.8s to as low as 0.2s, allowing near-instantaneous feedback during fast-paced operating.
In the ever-evolving world of amateur radio digital modes, software updates are the lifeblood of performance, reliability, and user experience. For operators who rely on FT8, FT4, and other QSO-centric modes, the name JT-DX has become synonymous with stability and advanced features tailored for the DXer and contester.
With the release of version 2.2.160—often searched as "JTDX 22160 new" —the development team has delivered what many are calling a significant leap forward. This article breaks down everything you need to know about this latest iteration: what’s new, why it matters, how to install it, and how it compares to WSJT-X. jtdx 22160 new
JTDX allows you to filter the Band Activity list.
From release notes and community discussions (sources: JTDX user groups, GitHub mirrors, and QRZ forums): One of the most anticipated "new" aspects is
| Feature | Description | |---------|-------------| | Improved FT8 decoding | Enhanced decoding algorithm for very low SNR (–22 dB or lower). Better handling of long-path and auroral flutter. | | Multi-stream decoding | Allows decoding of up to 4 FT8 signals simultaneously on the same frequency slot, reducing missed QSOs in crowded bands. | | Frequency calibration aid | Built-in tool to measure and adjust TX frequency offset using received FT8 signals from known reference stations. | | HamQTH / QRZ lookup integration | More reliable auto-fill of call, name, and grid. | | Waterfall improvements | Smoother scrolling, adjustable contrast, and separate color mapping for weak vs. strong signals. | | Logging enhancements | Direct ADIF export with custom fields; improved LOTW and eQSL flagging. | | Auto-sequencing flexibility | User can now interrupt and restart auto-sequences without resetting the whole QSO. | | Band-hopping support | Experimental feature to automatically move to another band if no decodes for a set period. |
The number 22160 refers to a specific software version – likely JTDX v2.2.160 (sometimes written as 2.2.160 or 22160).
In JTDX versioning: The number 22160 refers to a specific software
This version was released around late 2023–early 2024, depending on development cycles. It is not the latest as of mid-2026, but remains widely used because of stability and specific features.
This is where JTDX 22160 shines compared to stock WSJT-X.
JTDX (JTDecode X) is a fork of WSJT-X. Version 22160 likely refers to a build based on WSJT-X v2.2.1 or v2.1.0 logic but optimized for the specific needs of serious DX hunters.
RR73 rather than R-xx. It is a combined acknowledgment and 73. If the other station sees RR73, they know the QSO is complete.
