The Service Menu contains parameters essential for the functionality of the Phase Locked Loop (PLL) and the RF Power Amplifier. The exact numbering may vary by firmware version, but the functions remain consistent.

Final notes and best practices

Change the transceiver mode to the target band (e.g., AM or FM) via the switch. Adjusts the Peak Envelope Power for single sideband

: Changing values in the service menu without proper test equipment (like a frequency counter or signal generator) can significantly degrade the radio's performance or cause it to operate off-frequency.

The service menu of the AnyTone AT-5555N II is divided into several sub-menus, each containing a range of adjustable parameters. These parameters can include settings for transmitter power, frequency deviation, squelch sensitivity, and more. It is crucial for users to exercise caution when making changes in the service menu, as incorrect settings can potentially render the radio inoperable or cause it to malfunction.

While the service menu covers many settings, some hardware adjustments still require physical access to the radio's circuit board. This includes components like VRs (variable resistors) for functions such as ASQ (Automatic Squelch) and SSB power. This level of adjustment is for advanced users only.

Stabilizes phase-locked loop (PLL) tracking across different bands.

Controls the percentage of AM modulation. Setting this too high causes clipping and distorted audio.
