For more technically inclined users, the CP140 and its CPS offer deeper capabilities. The Global Tuner software allows for precise calibration of the radio's transmitter and receiver. Moreover, some enthusiasts have found that by modifying the Codeplug with a HEX editor, they can unlock frequencies outside the factory-set amateur bands, though this requires significant expertise.
