Where this data comes from

Happymodel's product post prints the block: Output power: 25~200mw switchable, Frequency: 40CH, Input voltage: 3.3V 5.5V, Current consumption: 300mA(type), Antenna: RG178 antenna U.FL interface, Frequency: 5.8GHz 5bands 40 channels, With Raceband, Smartaudio ready, Weight: 2g without antenna. input_voltage is that line read as the range it prints without a separator. power_levels_mw is off the one-page manual, which labels the board's three power test points 25MW, 100MW and 200MW and prints the 5-band 40-channel table (Band1 5865-5725, Band5/Raceband 5658-5917 MHz). The same manual carries a warning worth repeating: 'In the Smartaudio control menu, the vtx power is actually 200mw when it shows 500mw and it's actually 100mw when it shows 200mw' - this radio's own on-screen menu prints power steps it does not have, so an OSD photograph is not a source for this column. Discontinued; Happymodel names the OVX306 as the replacement.
