RUSHFPV 1.3/3.3GHz Dual-Band 2.5W
Of the 13 other 3.1-4.0 GHz analog video transmitters in our database, 1 has a lower maximum power than the 1.3/3.3GHz Dual-Band 2.5W (2500 mW, 34 dBm), 1 the same and 11 a higher one; the class median is 4000 mW. The 1.3/3.3GHz Dual-Band 2.5W steps through 25 / 200 / 1000 / 2500 mW, which is 14 / 23 / 30 / 34 dBm: the top level is 20 dB above the lowest, about 10.0x the free-space range on the same antennas.
RUSHFPV's own Betaflight VTX table is on this page: 4 bands of 8 channels, 1080–3470 MHz, 4 power levels. CLI commands and JSON file.

Power values are milliwatts, the steps the module's own label prints; the file names no control protocol. Bands as the file names them: BAND-A and BAND-B are the 3.3 GHz bands (3330-3470 and 3170-3310 MHz), BAND-E and BAND-F the 1.3 GHz ones (1080-1360 and 1200-1340 MHz). The file gives those four bands the letters A, B, A, B, which Betaflight cannot load; the letters stored are the ones the band names print (A, B, E, F). Ladder matches the label's PIT/25/200/1000/2500 mW; labels in the file are PA1-PA4.

Where this data comes from
Two SMA ports on one module: port B is 1G3, port A is 3G3, and the four bands (1G3A, 1G3B, 3G3A, 3G3B) are split two to each port, eight channels each. Label: power steps PIT / 25 / 200 / 1000 / 2500 mW, 7-30 V. RushFPV also sells a 4 W version of this module under the same product page; it has no label photograph of its own, so it is not published as a separate page and the 4 W figure is not written into this one. Output above the lowest step is licensed spectrum in most countries; the module's own label carries that reminder. Channels is 32 since 2026-10-17: four bands of eight, as RushFPV's own Betaflight table for this module holds them (bands A, B, E and F, eight frequencies each), which matches the four bands (1G3A, 1G3B, 3G3A, 3G3B) this note describes. RushFPV does not print 32 anywhere; the 8 this page showed until then was one band's count
