Transmitting & law

Transmit only when shielded

Muxwright generates real broadcast signals. Transmit only in a shielded setup: by cable with an attenuator, in an RF shielding box or in a test chamber. Never radiate on broadcast, mobile or other licensed frequencies. Radiating without a licence is illegal in most countries and can disrupt radio services.

Cabled: Pluto → DC block (for satellite) → attenuator(s) → device under test. 20–50 dB attenuation is a good start.
Use antennas only inside a shielding box or test chamber.
Muxwright starts muted, the emergency stop cuts output instantly, and a minimum attenuation can be enforced.
In Germany the TKG applies; radiating without a frequency assignment from the Bundesnetzagentur is not permitted. Check your local regulations.
Codecs and third-party programs: Muxwright ships none. You install FFmpeg (x264/x265), ODR-mmbTools with FDK-AAC, TSDuck and welle-cli yourself during setup from the official sources, each only after you confirm its licence. Private, non-commercial use of patented codecs (H.264, HEVC, AAC) is permitted in Germany under § 11 No. 1 PatG; for commercial use you obtain the patent licences yourself (Via LA, Access Advance, Sisvel). Check the rules in your country.
Licences: Muxwright is MIT-licensed, the FM/RDS part is GPL-3.0 (after PiFmRds, PiFmAdv, MiniRDS and gr-rds). The Pluto firmware is based on Analog Devices plutosdr-fw (GPL-2.0 and others); build instructions, changes and a written source offer come with the package.
Amateur radio: licensed radio amateurs may transmit in the amateur bands, e.g. DATV via QO-100 (uplink 2401.5–2409.5 MHz), with a harmonic filter and following the band plan and transponder rules. The broadcast standards (DAB+, FM, DVB-T/C/S, PAL) stay in the shielded lab even then.
