- Scanner frequencies for Formula 3 racing. Because F3 travels all over the world, you should verify whether scanners are legal in that country before bringing one to a race.
Team Radios
The vast majority of Formula 3 teams and officials (FIA and FOM) use a single TETRA digital trunked radio system for communications. This is provided by Riedel Communications. This provides up to 32 voice channels operating on x8 25khz wide frequency pairs each with 4 individual slots. Riedel supply Motorola MTP850 portable radios and Riedel MAX headsets to the teams. This system does not use encryption.
Since 2020, the Williams F1 Team switched from Riedel to a Kenwood NXDN Nexedge digital radio system supplied by MRTC Ltd. For 2021, McLaren F1 have also moved to this MRTC system. MRTC supply UHF Kenwood NX3320 portable radios. This system uses the NXDN9600 protocol. This system does not use encryption.
Team Frequencies
The Riedel TETRA system operates in the 420-430MHz range in 12.5kHz steps for the TETRA Base (downlink) repeaters. The subscriber (uplink) frequencies are in the 410-420MHz range, -10MHz below the Base frequency. The TETRA MCC is 262 and MNC is 0007. The system does not use any TEA encryption. The frequency allocations vary between races. The list below shows typical allocations for the 2021 and 2020 season.
The MRTC Nexedge system operates in the 450-470MHz range in 12.5kHz steps. The frequency allocations vary between races. The list below shows typical allocations for the 2021 season.| TETRA Channel | DOWNLINK FREQUENCY (MHz) | UPLINK FREQUENCY (MHz) |
