BTECH Releases Firmware 0.8.0 for GMRS-PRO and UV-PRO, Introducing Bluetooth VOX for Hands-Free Operation

Wednesday, January 29, 2025

ARLINGTON, SD – BTECH is proud to announce the release of Firmware 0.8.0 for its popular GMRS-PRO and UV-PRO radios, delivering groundbreaking enhancements that elevate both convenience and capability for radio enthusiasts and professionals. Chief among these updates is the all-new Bluetooth VOX functionality, allowing operators to seamlessly transmit hands-free with any Bluetooth headset—no special accessory required.

Bluetooth VOX: A Leap Forward in Hands-Free Communication

The hallmark feature of Firmware 0.8.0 is the Bluetooth VOX (Voice-Operated Exchange) integration, which changes how you interact with your radio in the field. By pairing a compatible Bluetooth headset, you can transmit simply by speaking—without pressing the PTT button. Key highlights include:

• Universal Bluetooth Compatibility: Eliminate the need for the dedicated BS-22 accessory. Connect virtually any Bluetooth headset to enjoy hands-free convenience.
• Customizable Audio Routing: Route audio through either the radio’s speaker or the Bluetooth device. This flexibility ensures you can tailor audio settings to your exact environment and preferences.
• Improved Signal Stability: Firmware 0.8.0 enhances overall Bluetooth performance, minimizing dropouts and echo, even when paired with third-party devices.

Whether you’re coordinating a search and rescue operation or simply looking for added convenience on the trail, Bluetooth VOX empowers you to stay focused on the task at hand.

Other Exciting Updates in Firmware 0.8.0

In addition to the marquee Bluetooth VOX functionality, Firmware 0.8.0 brings a suite of improvements and fixes to both the GMRS-PRO and UV-PRO:

Onboard Menu Enhancements

• Audio Relay Access (Store and Forward Repeater): Adjust audio relay settings directly on the radio without using the app.
• VOX Settings: Fine-tune VOX thresholds from the onboard menu, giving you greater control over sensitivity and trigger levels.

NOAA Enhancements 

• Scan Pause Function: NOAA scanning automatically pauses upon detecting a signal, letting you monitor critical weather updates without missing alerts.

• Streamlined ACK Handling: Resolved acknowledgment issues, ensuring smoother SMS-like communications on APRS.
• Automatic Resend: Messages resend automatically if no ACK is received, minimizing data loss in busy environments.
• Enhanced KISS Stability: Improved data transmission reliability and reduced message errors, a boon for digital mode enthusiasts.
