Midland 75822 Channel Mod (SECURE)
The channel modification (often called the frequency expansion or "export" mod) unlocks the internal microcontroller's full capacity. Because Midland used a highly adaptable printed circuit board (PCB) layout shared across multiple international versions (such as the 75-820), the physical architecture already supports extra bands.
This post is for educational and informational purposes only regarding radio theory and legal compliance. Modifying radio equipment to operate on unauthorized frequencies is a violation of FCC regulations in the United States and similar laws internationally.
This radio is a classic piece of CB history. Its value is in its original, legal operation. Enjoy it for what it was designed to do: reliable 40-channel AM communication. If you need extended range or more frequencies, get licensed for amateur radio – it’s more fun, fully legal, and opens up far more possibilities than a risky channel mod ever could.
While the mod provides more channels, these bands are often "dead" or have very low traffic unless used for private company communications or specific hobbyist groups. midland 75822 channel mod
The Midland 75822 channel mod is largely a myth for most production runs. The few who claim success likely own an early prototype or a different radio altogether (e.g., the Midland 1001Z, which is more mod-friendly).
The Midland 75822 is typically a 40-channel CB (Citizens Band) radio transceiver from the late 1970s or early 1980s. It operates legally on between 26.965 MHz and 27.405 MHz, with 4 watts of AM power.
To help you get the absolute best performance out of your radio, let me know: Enjoy it for what it was designed to
The most permanent way to access export channels involves configuring the logic board jumpers located behind the main LCD screen display.
How it works: Flip the switch up = +5V (Logical 1). Flip down = Ground (Logical 0). By changing the binary code, you shift the VCO frequency.
When successfully modified, the radio typically expands into an "export" format, unlocking: highly favored by off-roaders
Provides clear visibility of channel settings and signal strength.
Opening the casing or altering the internal circuitry immediately voids the manufacturer’s warranty.
The is one of the most versatile handheld Citizen Band (CB) radios on the market, highly favored by off-roaders, truck drivers, and emergency preparers. While it works perfectly out of the box with the standard 40 legal U.S. CB channels, radio enthusiasts often look to expand its capabilities using the Midland 75-822 channel mod
: This is a critical final step . After changing any jumper settings, you must temporarily bridge the two pads labeled "reset" on the PCB. This forces the radio's microprocessor to recognize the new configuration.
The key to understanding the channel mod lies in the radio's internal hardware. As a "synthesized" radio, the 75-822's channels are generated by a , a digital chip that controls the frequency. This very design makes the expansion possible, as the PLL chip is often capable of generating a much wider range of frequencies than the manufacturer chooses to utilize.
