SmartStreamer4 v0.1.20b is now available.

Extract the zip and run SmartStreamer4.exe. The Setup Guide on the Help tab walks you through the rest.

New in this release is support for digital modes, including the ability to configure and launch multiple instances of WSJT/X (one instance per slice).

• A new Launch tab is the app's home: connect to the radio, then start CW Mode (the CW Skimmer experience, unchanged) or Digital Mode.
• The streamer provisions each instance automatically: DAX RX audio device, SmartSDR CAT TCP port, unique UDP reporting port, and your call/grid are written into a per-slice profile. Your engine settings (window layout, band, FT8/FT4 choice) are preserved across launches.
• Per-slice Start/Stop on the Digital tab. Stop closes the engine gracefully so it saves its settings. A soft notice warns when a slice is not USB/DIGU (still launchable).
• Live-validated with two concurrent WSJT-X instances on SmartSDR 4.2.20 / DAXv2, including CAT, audio, and UDP port isolation per slice.

What it does:

• CW Mode: streams DAX-IQ audio into CW Skimmer (one instance per slice), keeps each instance synced to your panadapter and slice frequency as you tune and band-change, and publishes the decoded spots back onto your SmartSDR panadapter.
• Digital Mode (new in this release): sets up and launches WSJT-X, JTDX-Improved, or WSJT-Z, one instance per slice, several slices at once. The app writes each instance's configuration for you (DAX RX audio device, SmartSDR CAT TCP port, unique UDP reporting port,
  your call and grid), so you skip the per-instance setup dance entirely. Your engine settings (window layout, band, FT8/FT4) are preserved across launches. Works with the current DAXv2 architecture in SmartSDR 4.2.x.

Also in v0.1.20b: more reliable radio/station disconnect handling, multi-station fixes (shared DAX-IQ channels, Maestro station names), and a fully rewritten in-app Setup Guide with screenshots covering both modes, including step-by-step instructions for
creating the SmartSDR CAT TCP ports that Digital Mode uses.

Requirements: Windows 10/11, SmartSDR 4.x (extensively tested on 4.2.20)

CW Mode needs CW Skimmer; Digital Mode needs WSJT-X, JTDX, or WSJT-Z installed.
