DVS-M17 is a powerful tool that connects you directly to the M17 digital voice reflector network without the need for servers, accounts, or gateways. It uses the open-source digital voice protocol, which was built by hams for hams, utilizing the efficient Codec 2 vocoder. When you use DVS-M17, your Android phone or tablet transforms into a full M17 client that communicates using the UDP reflector protocol.

With DVS-M17, you can listen anywhere. The app allows you to browse over 100 reflectors from its built-in host list, which is updated from the DVRef directory. You can even enter listen-only mode, so there's no need to provide a callsign; just choose a reflector and listen to the conversations happening on the network. The Live Last Heard dashboard shows you who is currently talking on the reflector network, allowing you to easily engage with users. You can also enjoy multi-reflector scanning. This means you can monitor several reflectors at once through a single decoder, making it simple to jump in when something catches your ear.

When it’s time to join the conversation, DVS-M17 offers reliable push-to-talk functionality. You can link to any reflector module from A to Z with your callsign. Simply press and hold to talk, and you will see a live audio level meter to help you gauge your audio. The app features a half-duplex mode that mutes incoming audio while you're transmitting, similar to a traditional radio experience. If you prefer, you can pair a Bluetooth PTT microphone, like the Inrico-style speaker mics such as the PTT-Z01 or B01, allowing you to key the radio even with the screen off.

DVS-M17 helps you know who you are talking to with its live caller screen, displaying the transmitting station's callsign, name, and location via the RadioID database. You can also view a photo from QRZ.com. The app keeps track of your communications through call log tracking, recording every received and transmitted contact. Plus, a link quality indicator monitors real-time packet loss, helping you ensure good communication.

Built specifically for Android, DVS-M17 includes a user-friendly Jetpack Compose interface with dark theme support, making it easy to use on devices running Android 8.0 and later. The app works seamlessly over both Wi-Fi and mobile data, and it can keep receiving audio in the background while you use other apps. You can even open a reflector directly from a link thanks to its deep link integration.

Keep in mind that an amateur radio licence is required to transmit on a reflector, as your audio will reach the airwaves. However, listening and direct peer-to-peer calls over Wi-Fi do not require a licence. DVS-M17 can verify your licence against QRZ.com, RadioID.net, or AllStarLink, and it never stores your password for added security.

DVS-M17 operates under an open protocol, details of which can be found at the M17 project website. The app makes use of the open-source Codec 2, which is bundled under the LGPL-2.1 licence. Importantly, DVS-M17 collects no personal data and contains no advertising or tracking.

Whether you’re interested in M17 hotspot operation, handheld radio usage, or simply want to explore open-source digital voice, DVS-M17 is the easiest way to connect to the M17 network. Enjoy hassle-free communication without the complications of servers or tracking, and experience the world of digital voice with DVS-M17.
