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).

Frequencies just above CB (27.5–28.0 MHz) are allocated to government, aeronautical, and emergency communications. Accidentally transmitting there could disrupt critical services.

Note: Specific diode placements vary wildly by PCB revision. Midland changed components over the years. One user’s working mod may brick another’s radio.

The Midland 75822 uses a common PLL chip, often an or similar. This chip has several "binary code" input pins. By changing which of these pins receive voltage (high or low), you change the channel number.

Near the PLL chip, you should see a small grid of diodes or empty solder pads labeled something like "CH1, CH2, CH4, CH8" – these are binary weighting pins (1, 2, 4, 8). There may also be a "Band A/B" pad.

Frequencies dropping below 26.965 MHz (down into the 26 MHz range).

The 75822 supports (RP15–RP22). Many users mistakenly think they need a mod to access repeaters. Instead, simply:

: Opening the unit and soldering will immediately void your manufacturer warranty.

The mod typically increases the channel count from 40 to 120. Some users claim even higher counts (up to 400 channels), though 120 is the most common standard for this specific unit. Hardware Method: For many versions, the modification involves bridging specific pads

If you need more than 40 CB channels, you have three legal, high-performance options:

This mod targets the or equivalent chip (often an LC7137 or D8581 in Midland units). We will be manipulating the "binary" inputs to the PLL.

To modify the radio, operators must open the housing to expose the main logic board. Near the central microprocessor, there is a cluster of small configuration pads or surface-mount resistors (often referred to as jumpers).

By focusing on high-quality external antennas and proper power supplies, the Midland 75-822 remains a top-tier choice for portable and mobile CB communication without the risks associated with internal hardware tampering. Share public link
