Install the station app on your PC.
HamLink Bridge is the software that sits beside your radio. It tunes a local frequency, hears digital ham signals, and turns them into plain text — then syncs that text to your HamLink inbox.
After download: extract the ZIP, register this PC under Settings → Devices, then run python -m hamlink_bridge setup (or node hamlink-agent.js setup) and paste your Device ID and secret.

Frequency is local — not worldwide
HamLink never hard-codes one global frequency. Each country has its own recommended channel. Set yours in Settings → Regulatory Profile, then Bridge tunes the SDR to that frequency.
