Everything a node does.
Nothing a node costs.
QSO One is a complete amateur radio client for AllStarLink and EchoLink. Here's what's inside.
Full AllStarLink support, two connection modes.
QSO One connects to the AllStarLink network using the full IAX2 protocol — the same protocol used by physical nodes. Choose how you connect based on your registration status.
- Node Mode — connect using your registered AllStarLink node number and credentials
- WT Mode (Web Transceiver) — connect as a guest without a registered node
- Automatic HamVOIP server detection for optimal routing
- Four-step connection cascade that finds the right path every time
- Full DTMF support for controlling nodes and repeaters
- Directory of 39,000+ AllStarLink nodes with search and favorites

EchoLink that works everywhere.
Many EchoLink clients fail on cellular or behind CGNAT. QSO One includes automatic proxy fallback, so you stay connected even when direct UDP is blocked.
- EchoLink Direct — standard UDP connection for home and office networks
- EchoLink Proxy — automatic fallback when direct connection fails
- Works on cellular, CGNAT, and restricted networks where others fail
- Directory of 6,500+ EchoLink stations and repeaters
- Full DTMF support
- Requires a valid amateur radio license and EchoLink registration (free)

Stays connected. Even when your phone doesn't.
Most radio apps drop their connection the moment you switch apps or lock your screen. QSO One keeps the session alive with a persistent foreground service — designed for real-world mobile use.
- Persistent foreground service keeps your session alive on Android
- Stay connected while switching apps, taking calls, or locking screen
- Optimized for cellular networks with reconnect logic on network switches
- Low battery impact — connection maintained without excessive wake locks
- iOS support coming soon
