Universal CAT Control

Minimum required hardware

• PC with Windows 10 or later, 64-bit operating system.
• Some radios require an external connection interface (serial cable or USB→serial; for Icom radios, CI-V connection).
• PC sound card (or a simple USB adapter) to record and listen to audio.

Main features

• Free.
• Based on hamlib libraries (GNU LGPL license), supporting many transceivers (Icom, Kenwood, Yaesu, Elecraft and others).
• Multi-radio support: multiple radios configured in separate profiles, with simultaneous connection and immediate selection of the active one.
• Simple interface: frequency and functions via click and mouse wheel.
• Quick Split with ready-to-use offsets (+5/+10/+15 kHz).
• Quick Keys: save the entire radio state (frequency, mode, filter, split, levels, functions) with one click and recall it anytime.
• Custom widgets: create custom buttons and sliders that send raw commands directly to the radio, and place them anywhere.
• Mini widget: compact window always at hand with frequency, mode, band, VFO, split and your chosen controls.
• Memories and banks: scroll, jump, import, rename.
• VFO A/B/C, VFO/MEM, filters, passband, AGC, ATT, PREAMP and all functions supported by the radio.
• S-Meter and dynamic meters (SWR, power, COMP, ALC…) driven by HamLib.
• Plugins and external programs: an installable plugin system extends the program (including Audio Recorder and Web Radio UI).
• Direct frequency setting from external programs.
• PTT management (with partial/total TX counters) and radio commands.
• Built-in Audio Recorder: starts recording when squelch opens and stops when it closes.
• DXLab Commander Server: communicates with other programs such as DXLab Suite, MultiPSK, FLDigi, WSJT-X, N1MM and JT65-HF using the most common protocol.
• Virtual COM (com0com): exposes a virtual COM port to other programs as if it were a real radio (for QARTest, N1MM, fldigi…).
• Web Radio UI: control and listen to your radio from any device's browser (PC, tablet, phone), including transmission, with personal login and low-bandwidth mode for slow connections.
• Automatic updates verified from official sources, with no telemetry or background processes.
