saveSource: https://ft.systems/wp-content/uploads/2025/08/FT-VTX-1D2.zip — Copied from 'FT VTX 1D2.json' in the maker's settings download (https://ft.systems/wp-content/uploads/2025/08/FT-VTX-1D2.zip), linked from https://ft.systems/en/video-transmitter-vtx-ft-1-2/ as 'Settings File'. Every frequency matches the frequency table on page 4 of the maker's manual FT_VTX_instruction_1.2_GHz.pdf. The ninth channel, 1258 MHz, is the file's BAND_B CH1; the other seven slots of that band are 0, Betaflight's unused slot. Power values and labels are the file's own: its lowest step is labelled 0 but commanded as 9 mW, as on FT's 4.8-7.2 GHz file.. Transmitting is only legal on the frequencies and power your country allows; see VTX frequency bands.

Where this data comes from
Ukrainian-made transmitter: 9 channels (one band) over 1080-1360 MHz, an aluminium heatsink with a fan, controlled over IRC Tramp. FT Systems quotes measured RF output of 3680-4530 mW across the range rather than one figure, because the amplifier does not deliver the same power at every frequency - the 4000 mW here is the nominal top setting. No weight: the product page says 30 g and the maker's manual 25.85 g for the same 53x28.85x16 mm body, so the two maker sources disagree one against one. Outside the 5.8 GHz band this is not a licence-free link in most countries; check local rules before transmitting. FT prints the connector as 'SMA female'; the column holds one spelling per connector.
