Complete Guide to the Anytone AT-5555N II Service Menu: Alignment, Calibration, and Hidden Settings
While the service menu calibrates the hardware parameters , it does not unlock the frequency bands (10/11/12 meters). Band unlocking is still handled via the physical internal PCB jumper pads or by using the official Anytone PC programming software with a USB data cable.
Depending on your specific firmware revision, utilize one of the following methods.
Older versions of the AT5555N (the first generation) had a notoriously simple, albeit limited, service menu. However, with the "N II" revision and subsequent firmware patches (Version 2.0 and higher), AnyTone has expanded the service menu to include: anytone at5555n ii service menu updated

The Anytone AT-5555N II service menu is a powerful tool for frequency expansion and alignment. However, the "Updated" versions of this radio have introduced variability in how these menus are accessed. Users should verify their PCB revision before attempting modifications. For precise alignment, always utilize external test equipment (Wattmeter, Frequency Counter, and Deviation Meter) rather than relying on the radio's internal uncalculated display.

| Menu Item | Parameter | Factory Setting (Example) | What It Does | | :-------------- | :---------------------------------- | :------------------------ | :---------------------------------------------------------------------------------------------------------------------------------------- | | | Phase-Locked Loop Reference | 0 | The master reference frequency for the radio. Do not adjust without advanced test equipment and a frequency counter. | | AM HI PWR | AM High Power | 20 | Controls the maximum AM transmit power output. | | AM LO PWR | AM Low Power | 12 | Controls the AM low-power setting. | | FM HI PWR | FM High Power | 44 | Controls the maximum FM transmit power output. | | FM LO PWR | FM Low Power | 12 | Controls the FM low-power setting. | | SSB HI PWR | SSB High Power | 87 | Adjusts the maximum SSB power output. | | SSB LO PWR | SSB Low Power | 20 | Adjusts the SSB low-power setting. | | FM DEV | FM Deviation | Unknown | Adjusts the FM deviation level. This is a critical setting for FM clarity. Some users wish it were higher from the factory. | | AM TONE / FM TONE / USB TONE / LSB TONE | Mic Audio Tone Shaping | Unknown | These likely adjust the equalization or "tone" of the transmitted audio for each mode, affecting the voice's character. | | RXBPF | Receive Band Pass Filter | Varies | Adjusting this parameter can alter the received audio quality. Some users increase it to reduce a "thin" or "far away" sound. | | ALC | Automatic Level Control | Unknown | Controls the ALC, which prevents over-driving the transmitter. Critical for clean, clear transmissions. |
