TetraSpot
TETRA base station (hotspot)
A homebrew TETRA base station that fits on a desk. The first amateur project in the world to bring a home TETRA base station to full functionality.
What it does
- Group and individual calls like on a real network
- Messaging and terminal locations on a map
- Internet access and browsable pages straight on the radio
- Bridges your radios into the nationwide TetraPoland network
- Runs on a single small computer
A TETRA base station normally means a rack of equipment and a budget no radio amateur has. TetraSpot brings it down to one small computer on a desk — and one that behaves like a real network: terminals see it, register to it and talk through it exactly as they would through professional infrastructure.
What it does
- Broadcasts as a valid TETRA network — terminals find it and register
- Group and individual calls, including simultaneous two-way
- Floor control for half-duplex conversations
- Individual and group text messages, with store-and-forward delivery
- Terminal location — live positions on a map
- Internet on the radio — data transfer over the TETRA network
- Browsable pages right on the radio's display: station status, call log and messages
- Two carriers at once — more simultaneous calls and a separate channel for data
- Radio and station positions reach APRS maps
- Optional authentication with a list of permitted terminals
- Over-the-air rekeying
- Dynamic talkgroup assignment
- Telephone gateway — calls to and from the phone network
- Cellular gateway — a text message from a phone reaches the radio and back
- Reading and writing radio settings straight from the panel — no vendor software needed
- An echo service to test your own radio single-handed: you speak and hear yourself back
- Browser management panel: live view, call logs and configuration
- A ready-made memory-card image — the station arrives set up for your callsign and frequencies
- Updates arrive on their own and are digitally signed — a forged one is rejected
In development
- Support for several base stations at once
- A faster data channel — several timeslots at once
- Retransmission of lost fragments
