SDR-SLC Client

A native macOS application that turns your Mac into the control head and display for a software-defined radio. Built in Swift and SwiftUI, no browser, no cross-platform wrapper.

What it does

• Live spectrum and waterfall, with zoom from a full-span view down to a few kHz.
• Multiple receiver slices : work several signals at once, each with its own frequency, mode, filter and S-meter.
• All the modes : LSB, USB, AM, FM, CW, and the digital modes DIGU / DIGL.
• Digital voice : D-STAR, YSF and DMR.
• Transmit : full transmit control, with mic gain, compression and repeater shift.
• HF and VHF/UHF : one client, any supported backend.
• Finds your radio automatically : devices are discovered on your network via Bonjour, so you usually just pick your radio from a list.
