RUSHFPV Max Solo X-Band 4.9GHz 2.5W
The Max Solo X-Band 4.9GHz 2.5W steps through 25 / 500 / 1000 / 2500 mW, which is 14 / 27 / 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: 1 band of 8 channels, 4990–5200 MHz, 4 power levels, IRC Tramp. CLI commands and JSON file.

saveSource: https://drive.google.com/file/d/10kHFTK1MQJHF28mgbOxkeXWN_hDbtNM0/view — Copied from the maker's Betaflight file MAX_SOLO_X-BAND_4.9G_VTX.json in the RushFPV VTX Table Drive folder linked from rushfpv.net's Download Center. Power values are milliwatts, the steps the module's own label prints; the file names no control protocol; IRC Tramp is the maker's own spec sheet ('EXTERNAL CONTROL: IRC Tramp' / 'Protocol IRC Tramp', read 2026-10-20, burst 229). One band of eight channels 4990-5200 MHz in 30 MHz steps; ladder 25/500/1000/2500. The case label prints no power steps, so the file is the only maker source for them.
Transmitting is only legal on the frequencies and power your country allows; see VTX frequency bands.

Where this data comes from
The 4.9 GHz X-Band version of the Max Solo. Its case label reads 'CVBS A/V Transmitter, 7-36V DC-IN / 5V 500mA DC-OUT', MMCX, SH1.0 six-pin, and a separate AUD / 5V / GND microphone header; RushFPV's dimension drawing gives 40 x 24 x 10 mm. The 2.5 W is the manufacturer's own model name. Output above the lowest step is licensed spectrum in most countries; the module's own label carries that reminder. frequency_range, channels, power_levels_mw and weight_g are RushFPV's own 'MAX SOLO VTX [X-BAND] User Manual' (the listing's description image 4.9g_max_solo.jpg, 2031x4535), Specification block: 'CHANNEL: 8CH X-BAND 4990-5020-5050-5080-5110-5140-5170-5200', 'POWER LEVEL: PIT-25mW-500mW-1000mW-2500mW', 'INPUT: DC 7-36V (6S LiPo)', 'ANTENNA CONNECTOR: MMCX 50Ω', 'EXTERNAL CONTROL: IRC Tramp', 'SIZE: H 40mm* W 24mm* D 10.5mm', 'WEIGHT:15g (With out cable)'; its VTX TABLE screenshot matches the stored Betaflight file cell for cell.
