It is important to note that the Federal Communications Commission (FCC) and similar international bodies strictly regulate the frequencies and power levels allowed for Citizen Band (CB) radio. Operating on frequencies outside the standard 40-channel range or exceeding authorized power limits is illegal and can interfere with critical communications, including emergency and military services.
Unlike older classic CBs (Uniden, Cobra 148, etc.), the Midland 75-822 uses a microcontroller that integrates the channel selector and PLL control. Many have an internal EEPROM that locks the channel steps. Simply adding diodes may have no effect. midland 75822 channel mod
None of these require soldering on a fragile PLL. It is important to note that the Federal
Operating a radio that has been modified to transmit outside of its type-accepted frequency range is a violation of federal law in many countries. This can lead to heavy fines and the seizure of equipment. Optimizing Performance Within Legal Limits Many have an internal EEPROM that locks the channel steps
: After reassembly, the radio should power up on "6L" or allow scrolling past channel 1 down into the "Low" (L) band and past channel 40 up into the "High" (H) band. Advanced Operational Features
While not encrypted, these additional frequencies are less frequented by casual users, offering a degree of "quiet" for groups. Peak Tuning:
