The 75822 supports 8 GMRS repeater channels (RP15–RP22). Many users mistakenly think they need a mod to access repeaters. Instead, simply:
Look for a 16-pin or 18-pin IC near the VCO (Variable Capacitor Oscillator) can. It is usually labeled IC1 or IC2.
The Midland 75-822 is famous for its flexibility (it runs on AA batteries or a vehicle power cord). However, like many standard CB radios, it is locked by the FCC to 40 channels. Enthusiasts often perform "mods" (modifications) to unlock additional frequencies, commonly known as "Extra Channels" or "Expanded Band." midland 75822 channel mod
⚠️ Disclaimer: Modifying your radio to transmit on frequencies outside the standard 40 CB channels may violate FCC regulations (Part 95) in the United States. Transmitting on restricted bands (such as government or amateur radio allocations) can result in significant fines. This guide is for educational and theoretical purposes only.
If you own a Midland 75822 (often part of the "75-822" or similar legacy series), you might have stumbled across old forum posts mentioning a "channel mod" or "expansion." Before you reach for a soldering iron or try to clip a wire, let’s break down what that actually means, whether it’s possible, and—most importantly—why it’s probably a bad idea.

The most common legitimate "mod" is to activate the NOAA Weather Radio channels (162.400–162.550 MHz), which are often hidden by default.
Before fully closing the case, temporarily connect power and an antenna. Using a frequency counter or a second receiver, test a few "new" channels: If you own a Midland 75822 (often part
If you hear nothing or see no frequency change, the mod failed. You may need to reverse the changes.
