saveSource: https://docs.speedybee.cn/en/fpv/vtx_vrx/tx800/tx800-vtx-table.html — SpeedyBee's own Betaflight config file, "SpeedyBee-TX800(USA&CE).json", linked on its "TX800 VTX table" page; its description reads "for IRC Tramp (US version)", the protocol the manual sets in Ports. The five bands of eight are the manual's "Frequency Table" (Band A/B/E, Airwave, Race Band) with three slots zeroed - Band E CH4 5645, CH7 5925 and CH8 5945 - which is the US version the file is named for; the manual prints them and notes "Orange is a disabled channel in locked state", so 37 of the 40 slots transmit. The four labels are the manual's button ladder (25/200/400/800 mW) and the file repeats its top level twice (value 600, label "800"); it is stored as published. The label is the OSD text and the value is what Betaflight sends over Tramp, so the "800" label on value 600 is SpeedyBee's own figure.. Transmitting is only legal on the frequencies and power your country allows; see VTX frequency bands.

Where this data comes from
Brand corrected from RunCam to SpeedyBee: the board's own silkscreen reads SpeedyBee TX800, SpeedyBee sells it and hosts its manual, and RunCam is the vendor field of the RaceDayQuads listing the scrape read - a shop's supplier, not the part's manufacturer. The slug still carries the wrong brand because a published URL does not move, and model_set drops the 'SpeedyBee' the title carried: clean_model() strips the brand it was given, so a corrected brand leaves its own name printed twice. Cited against SpeedyBee's own TX800 user manual, which prints: Power in 3.7-5V, Power out 5V, board 28x28mm with the four holes on a 20x20mm pattern, 'Long press 5 seconds to enter POWER mode; each 5-second press switches to 25/200/400/800mW in sequence', and a 5-band 8-channel frequency table (A, B, E, Airwave, Race Band) running 5645-5945 MHz - 40 channels, which is what channels holds. frequency_range keeps the 5.8 GHz class label this column uses for the band. SpeedyBee's knowledge base repeats the four power steps per LED state but heads the band question 'switch between Band1/2/3/4/5/6' - six bands is the TX ULTRA's table, not this radio's, so a brand's FAQ can carry a sibling's figure the way a retail listing can. Discontinued: the TX800 is gone from speedybee.com's catalogue and survives only in the downloads and the knowledge base.
