macOS companion

The desk for
radio hunters.

CW Sweep is the macOS companion to Carrier Wave — a wide-screen workspace for spot hunting, contesting, and CAT-controlled operating, synced live with your iPhone log over iCloud.

Release notes

Universal binary — Apple Silicon & Intel · macOS 14 Sonoma or later

Built for big screens.

What you can’t do on a phone.

Spots

Live spot pipeline

RBN, POTA, SOTA, WWFF, and DX cluster spots merged, deduped, and enriched with distance and bearing.

Bandscope

Wide-band waterfall

Drive an SCU-LAN10 or KiwiSDR with synchronized VFO marker and click-to-tune integration.

CAT

USB & BLE radio control

Native CI-V, Kenwood, and Elecraft protocols over serial. Bluetooth keying via the CW Bridge.

Logger

Keyboard-first logging

Vim-mode bindings, command palette, and parsed entry that matches the way contesters actually type.

Sync

Same log as your phone

SwiftData over iCloud — QSOs entered on the desk show up in the field, and vice versa.

Updates

Stays current automatically

Sparkle-powered in-app updates — new builds arrive the day they’re notarized.
