Overview
Retevis packs APRS text messaging, GNSS positioning and Bluetooth app control into the Ailunce handheld, a dual band radio for the two meter and seventy centimeter bands. A KISS TNC links it to phone apps for messaging when cell service drops, and a waterproof shell handles rain and brief dunks.
Buy it for off-grid messaging and position sharing on hiking trips and events, with programming by app, keypad or CHIRP. The latest APRS and CHIRP features require a firmware upgrade before they appear.
Who it's for
Made for hikers, emergency volunteers and event coordinators who need position tracking and texting where phones fail. Casual users who just want push-to-talk on shared channels will find it complex.
Pros and cons
- APRS text messaging
- Fast GNSS positioning
- Bluetooth app setup
- Dual PTT and dual watch
- Firmware upgrade needed for new features
- Complex for beginners
Performance notes
Positioning speed comes from multi-system satellite reception, which holds a fix among buildings and in valleys. Messaging reach depends on getting to APRS gateways or other radios, so terrain and antenna placement decide coverage. Dual watch monitors two channels without crossover.
