AURSINC MMDVM Duplex Hotspot Radio Stationa – for stable, high-performance amateur radio digital voice communication!
Built with the Raspberry Pi Zero 2W, this upgraded duplex model delivers faster data processing, lag-free WiFi connectivity, and unmatched operational stability, outperforming single-band alternatives.
Designed for both beginners and seasoned hams, setup is a breeze. We’ve pre-loaded the Pi-Star software on the included TF card, so you can skip tedious downloads and get started in minutes.
Dual-band support : it covers UHF (433-900MHz) and VHF (144-146MHz) bands, including key frequencies like 144-148MHz, 420-475MHz, and 842-950MHz, with the 430-440MHz amateur band optimized for the best signal quality. The upgraded duplex design simplifies configuration too—TX and RX offsets are default 0, eliminating complex parameter adjustments.
Versatility: This hotspot works seamlessly with 6 major digital voice protocols (C4FM, YSF, NXDN, D-STAR, P25, DMR), adapting to your specific communication needs. Whether you’re communicating locally or linking to global networks, it’s got you covered. Please note it’s not compatible with Baofeng UV/BF series radios.
The WiFi connection is tailored for reliability: just ensure you’re on a 2.4GHz network (WPA password required), power on, and wait 2 minutes for auto-connection—then access the intuitive web configuration page at pi-star/admin/configure.php to customize settings.
Onboard LED indicators let you quickly check transmit/receive status, PTT activation, and operating mode at a glance. The pre-loaded firmware supports one-click software upgrades, and the dual Pi-Star control modes (Duplex/Simple) let you switch based on your skill level.
Upgrade the firmware: Press and hold the BOOT button to power on the device. Or press and hold the BOOT button at any time, then press the RST button briefly and release it. When the SVC light goes off, the device enters the upgrade mode (Access path: pi-star / Expert / SSH Access; Username: pi-star; Password: radpberry). You can execute the upgrade command directly without setting jumpers. (Execute in the Pi-star terminal): sudo pistar-mmdvmhshatflash hs_dual_hat.
Quality you can trust: every unit undergoes comprehensive testing, featuring a 32-bit ARM processor and reliable RF performance. To verify signal transmission/reception, visit m7spi.co. uk/mmdvmcal/ for testing tools. If you encounter network connection issues or have any questions, our support team is ready to assist—your satisfaction is our top priority.
