🔀Multi-Radio

What it does

• Eight operating modes, switched with a single button
• Registers on the network, joins talkgroups, transmits and receives voice
• Text messages with delivery reports and position reports on a map
• Driven from a touch front panel, your phone or a browser

Normally every communication system means another radio and another bill. Multi-Radio flips that: one small device covers eight operating modes, and you pick the one you're working in with a single button. Everything needed to log in is entered online — no programming cable, no vendor software, no codeplug procedure.

Modes that work today

• Analog FM — receive and transmit, narrow- and wideband
• TETRA DMO — direct mode and repeater
• TETRA TMO — terminal registered on a network
• DMR — two-way voice, confirmed on air against a commercial handset
• P25 — voice reception and transmission, verified on real off-air traffic
• D-STAR — two-way voice, confirmed on air against a commercial handset
• YSF — full voice path in both transmission modes
• M17 — the open digital standard, receive and transmit

Where it helps

• An affordable terminal where a commercial radio costs too much
• A monitoring and test position while building out a network
• Learning and experimentation — full insight into what's on the air
• Eight systems from one device, without buying eight radios

What it does in TETRA mode

• Network registration with authentication
• Joining talkgroups
• Group and individual calls — setup and release
• Voice reception
• Text messages — sending, receiving and delivery reports
• Statuses and position reports
• A view of network parameters and received signal level

What it does in the digital modes

• DMR: live monitoring — who is transmitting, on which talkgroup and frequency
• DMR: voice transmission straight to air with a PTT button
• DMR: your own ID, talkgroup, Color Code and power set from the app
• P25: voice reception and transmission, with radio and talkgroup identifiers
• P25: automatic monitoring — digital mode switches itself on
• D-STAR: two-way conversation with a commercial radio, with text alongside the voice
• YSF and M17: two-way voice, with your own callsign and group
• An S-meter plus receive and transmit indicators in every mode

Three ways to drive it

The radio doesn't force one interface on you — you drive it whichever way suits the moment. All three show the same state and work together: you can key up from the front panel while speaking through your phone.

• A touch front panel — the physical display that turns this into a radio rather than a computer: PTT, tuning, squelch, encryption and mode switching under your finger, without opening anything
• The panel connects over Bluetooth or by cable — over Bluetooth it needs nothing but power
• An Android app — full control from your phone, Bluetooth as the primary link, network as the fallback
• The app also carries the audio: microphone and speaker, PTT and live monitoring
• A browser panel — the same functions when you're at a computer

In development

• Voice transmission in networked TETRA mode
• Mutual authentication
• Packet data
• Operating in several modes at once
