Overlanding and off-road groups find immense utility in moving communication off the public channels to secure a dedicated, clear channel for trail spotting and logistics without constant interruption.
The most common modification for this radio was popularized by the "Midland 75-820 120-channel mod," which applies to the 75-822 due to their identical PCB layout, unlocking three distinct 40-channel banks: Standard (the standard 40 CB channels), Low (40 channels below the standard range), and High (40 channels above the standard range). This results in coverage from approximately 26.515 MHz to 27.855 MHz. More extensive modifications can enable up to 400 channels across ten bands, covering from 25.615 MHz to 30.105 MHz. midland 75822 channel mod
Even if the frequency range is expanded, the Midland 75-822 remains an AM-only transceiver. Most communications on expanded "freeband" frequencies utilize Single Sideband (SSB) modulation. Without internal SSB hardware or a clarifier knob, the modified radio would still be unable to effectively communicate with many operators in those expanded bands.
