Depending on your computer, you will need to choose the correct build. If you tell me your setup, I can point you to the right one: Are you using Windows (32-bit or 64-bit), Linux, or macOS?

Do you prefer the standard version or the multicast (widely used for JTAlert) version?

Are you running an older PC that might require the "Light" (low CPU) build?

7. Performance tips for v2.2.160

• CPU usage – set Rx decode depth to Fast on low‑end PCs, Deep on modern ones.
• Waterfall speed – 15 fps is enough; higher slows UI.
• Reduce QRM – Check Flatten (noise floor normalization).
• Clock sync – Use Dimension 4 (Windows) or chrony (Linux). JTDX needs ±0.5 sec accuracy.

🕒 If you see “dt” > 0.8 in decode line, your PC clock is drifting – resync.

Standard FT8 QSO (auto‑sequence)

1. Select Mode → FT8
2. Set Tx frequency (e.g., 1000–3000 Hz in waterfall)
3. Click Enable Tx
4. Double‑click a CQ in the Band Activity window
5. JTDX will auto‑reply with:
   • CALL RST → RST CALL → RR73 → 73

1. Enhanced Decoding Depth (The "Deep Decode" Engine)

The most significant change in JTDX 22160 is the optimization of the FT8 deep decoding algorithm.

• What’s new: The software now performs up to 5 decoding passes on the same time slice without increasing CPU lag.
• The result: Users in high-noise urban environments report decoding signals at -28 dB that older versions missed entirely.
• Why it matters: During auroral conditions or low sunspot numbers, those extra 2-3 dB of sensitivity mean the difference between a QSO and a "CQ no reply."

What is JTDX? (A Quick Recap)

Before diving into the specifics of version 2.21.60, it is worth remembering why JTDX exists. Originally forked from WSJT-X (developed by Nobel Laureate Joe Taylor, K1JT), JTDX focuses on high-throughput decoding and low latency.

While WSJT-X is fantastic for casual operation and rovers, JTDX has historically decoded up to 250% more signals in a single cycle during heavy traffic (e.g., the ARRL RTTY Roundup or the FT8 Roundup). The "22160" update refines this philosophy for the modern HF landscape.
