Aligns the master reference crystal oscillator (TCXO/VCO) to ensure the radio transmits and receives on the exact center frequency.

The BFO is essential for Single Sideband (SSB) operation. It allows the radio to reinsert the suppressed carrier required to demodulate USB and LSB signals. Proper alignment ensures that the audio heard is natural and that the transmission is centered on the correct frequency. 2.

The AnyTone AT-5555N II service menu is a powerful diagnostic and calibration tool, not a toy for "free power." When used with proper test equipment (frequency counter, watt meter, dummy load), it can resurrect a radio that has drifted off frequency or fix low modulation. anytone at-5555n ii service menu

If you own an , you already know it’s one of the most feature-packed 10-meter/12-meter radios on the market. But did you know there’s a hidden "Service Menu" that lets you fine-tune everything from transmit power to meter calibration?

Note: Navigation is typically handled by rotating the knob, and changes are saved by pressing the FUNC or PUSH knob. Key Service Menu Parameters Explained

To see the current numerical value of a setting, press the PTT (key the mic) . Anytone at-5555n II (version 2) | Page 39

can be interfaced with compatible programming software. This allows for easier organization of memory channels, Roger Beep settings, and display preferences through a visual interface on a computer. This method is generally safer for users as it typically restricts access to the critical internal alignment data found in the service menu. ANYTONE 5555n First Impression Learning

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

Ensure your SWR (Standing Wave Ratio) is as low as possible to protect the final transistors. Proper alignment ensures that the audio heard is

: To clear all settings and return to defaults, hold FUNC and SCAN while turning the radio on.

To access the factory service (hidden) menu on the Anytone AT-5555N II, you must perform a specific button sequence during startup. This menu is used for internal hardware calibrations and should be used with extreme caution. Access Procedure : Ensure the radio is powered OFF.

Use the alignment menu to tweak modulation parameters up to maximum safe limits (typically up to 63 on standard firmware variants).

An accurate, calibrated meter (like a Bird 43 or a high-quality Daiwa/Dosy meter) to verify true RMS and PEP power output.
