The Midland 75-822 is designed for specific thermal and electrical parameters. Attempting to bridge internal components or modify the circuitry can lead to:
Skips over factory-blocked frequencies to give you a continuous spectrum. How the Modification is Performed
It is important to note that not every 75-822 is modifiable. Like many popular devices, the 75-822 has had multiple production runs. Users on CB forums have noted that , with the typical jumper mod no longer functioning. This is likely due to Midland updating the firmware or hardware to prevent tampering. While alternative methods may exist for newer models, they are far less common and often unverified.
The 75822 supports (RP15–RP22). Many users mistakenly think they need a mod to access repeaters. Instead, simply:
In the United States, CB radios are governed by the Federal Communications Commission (FCC) under Part 95 rules. These rules ensure that the airwaves remain organized and accessible for everyone. midland 75822 channel mod
| | Legal Solution | |----------|--------------------| | More CB-style channels | Get a 10-meter amateur radio (requires Ham license) | | Short-range, license-free | MURS (151–154 MHz) or FRS/GMRS (462–467 MHz) | | Long-range HF voice | Amateur Radio license (Technician or General class) | | Just more CB channels | Most modern CBs already cover 40 channels – that's all you get legally |
Frequencies just above CB (27.5–28.0 MHz) are allocated to government, aeronautical, and emergency communications. Accidentally transmitting there could disrupt critical services.
So, why would someone want to perform a channel mod on their Midland 75822? Here are some benefits:
The true value of this mod is the access to new spectrum. The standard CB band (Mid) covers from . The mod adds 40 channels below and 40 channels above this range, providing access to a total of 120 channels. The Midland 75-822 is designed for specific thermal
Connecting the unit to a high-quality, properly tuned external vehicle antenna can drastically increase range compared to the handheld "rubber duck" antenna.
However, it's essential to consider the following:
a popular internal modification allows users to expand its capabilities to 120 channels Unlocking the 120-Channel "Uppers and Lowers" Mod The modification opens up the
Depending on the board version, bridging a specific set of open pads with a solder blob or removing a specific zero-ohm resistor/diode tells the microprocessor to boot up in multi-band mode. Like many popular devices, the 75-822 has had
Some users modify this radio intending to use it on the 10-meter Amateur band (28 MHz). However, the PLL (Phase Locked Loop) in the 75-822 usually does not tune that high. The modification typically only opens up the "CB Band" guard bands (26-27 MHz), not the 10-meter ham band.
This modification unlocks two additional bands of 40 channels each, flanking the standard CB frequencies.
For those interested in exploring more frequencies and higher power levels, obtaining an Amateur Radio (Ham) license is a great path forward, as it grants legal access to a wider range of the radio spectrum.
The Midland 75-822 is strictly an AM (Amplitude Modulation) and NOAA weather alert radio. Unlocking extra frequencies does not magically give you FM or Single Sideband (SSB) capabilities. Because most international "freebanders" use SSB (USB/LSB) or FM on high/low channels, you will still only be able to communicate with operators using standard AM modulation on those frequencies.
