Connect Your Radio
Plug a BTECH or compatible two-way radio into your Android device using a standard K1 audio cable.
VibeRepeater
Radio-to-PTT Bridge for Android
Connect your two-way radios to ZelloWork channels. Bridge existing radio infrastructure with mobile teams anywhere — no extra hardware required beyond your phone and a cable.
How It Works
Join a Channel
VibeRepeater connects to your ZelloWork channel and begins listening for traffic from both sides.
Bridge Audio
Radio transmissions are relayed to ZelloWork users, and ZelloWork audio is transmitted over the radio — automatically.
Features
Bidirectional Audio Bridge
Seamlessly relay audio in both directions between radio and PTT with automatic VOX detection.
Background Operation
Runs as a foreground service — keeps bridging even when the screen is off or you switch apps.
No Special Hardware
Just an Android phone and a K1 audio cable. Turn any compatible radio into a network-connected repeater.
Encrypted Streams
All network audio is encrypted in transit via TLS. Your communications stay private over the internet.
Configurable Audio
Adjust VOX sensitivity, audio gain, and transmission delay to match your radio and environment.
Built-in Debug Logging
One-tap bug reports with full diagnostic logs to help troubleshoot connection or audio issues.
