Anytone At5555n Ii Service Menu Work [upd]

Correct minor frequency drifts in Single Sideband (SSB) mode by adjusting the reference oscillator value.

Immediately press the remaining front-panel buttons in sequence, starting from and moving right toward EMG (DW, RB, NB, SCAN, MEM, EMG).

The service menu is a hidden software interface built into the radio's microprocessor. Unlike the standard user menu—which controls basic operational settings like key tones, screen color, and scan lists—the service menu directly alters the hardware calibration.

A: The service menu is for calibration, not for changing the fundamental band coverage. Attempting to use it for such purposes is generally not possible and could violate radio regulations.

is an exceptionally popular 10-meter amateur transceiver, widely favored for its robust output, advanced digital noise reduction (NRC), and flexible configuration . However, straight from the factory, the radio may not always achieve peak performance. Variations in factory calibrations, ambient temperatures, and integration with external linear amplifiers often require operators to dive deeper than standard user menus allow.
