Anytone At5555n Ii Service Menu Updated

Depending on your specific firmware revision, utilize one of the following methods.

Q: Why is the old "MENU + POWER" trick not working? A: The updated firmware (V2.0+) disabled that backdoor to prevent hamfisted adjustments. You must use the BAND+INFO method described above.

Q: Will resetting the radio (Factory Reset) reset the service menu? A: No. A standard factory reset (FUNC+INFO on power up) only resets user settings (channel memories, mic gain, RF power). The service menu parameters are stored in a protected EEPROM sector and remain untouched. You must manually revert changes.

Q: I bricked my radio by adjusting P-01. Help? A: If the VCO unlocks, you will hear clicking. Turn the radio off. Open the case and look for the two VCO trimmer caps (TC1/TC2). If you didn't touch those, re-enter the service menu blindly (you may need a strong signal in the room to hear beeps) and set P-01 back to 2.5.

The AnyTone AT-5555N II is a high-performance 10-meter radio, but many of its most critical calibration settings—like power output and modulation—are tucked away in a hidden Service Menu. Because there is no factory "reset" for this specific menu, users must exercise extreme caution when making adjustments. How to Access the Hidden Service Menu

Accessing the service mode requires a specific sequence of button presses during the power-on cycle.

Preparation: Ensure the radio is connected to a dummy load or an antenna to prevent damage.

Initial Combo: With the radio OFF, press and hold both the [MENU] and [MODE] buttons. Power On: While holding those buttons, turn the radio on.

Secondary Sequence: Once the radio powers up, release the initial buttons and immediately press the following top-row buttons in order: [DW], [RB], [NB], [SCAN], [MEM], and [EMG].

Entry Confirmation: If successful, the display should show "FM" (representing the factory menu) or a numerical setting. Navigating and Saving Settings

Scrolling: Use the Channel Selector knob to cycle through different menu items (ranging from 1 to over 50).

Viewing Values: To see the current value of a setting, press the PTT (Push-To-Talk) button on the microphone. Do not trust random YouTube videos or forum

Changing Values: To modify a value, hold the PTT while rotating the Channel Selector. Saving: Turn the radio off to save your changes.

CRITICAL WARNING: Always WRITE DOWN every original value before changing it. There is no software reset for these specific alignment values; if you change them without a backup, you cannot easily restore factory calibration. Key Service Menu Items and Fixes

While the radio lacks official documentation for every item, community testing has identified several critical settings for the AT-5555N II: Description #16 AM High Power Adjusts the peak dead key for AM high power mode. #17 AM Low Power

Adjusts the low power dead key (often set to 2 watts for amp driving). #19 & #20 Modulation Some users set these to "0" to improve AM modulation swing. #52 (RFG) RF Gain Fix

Used to resolve "S5-S7 noise" issues. Increasing this value (e.g., from 86 to 105) can quiet a noisy receiver. Frequency Expansion (Export Mode)

If you are looking to unlock the full 11-meter and 12-meter bands (25.615 to 30.105 MHz), follow this separate procedure: Turn the radio OFF. Hold [FUNC] and [EMG] and turn the radio ON. Rotate the channel knob to select "BAND 2". Long-press [FUNC] until the display shows "rEND". Power cycle the radio.

To enter the hidden service menu, follow this specific power-on sequence: Turn off the radio.

Press and hold the FUNC button while turning the power back on.

Release FUNC and quickly press the following buttons in sequence: RB → NB → DW.

The display will change to show alignment codes. You can then use the MODE switch to access settings for specific modes (AM, FM, USB, LSB) and the FUNC button to scroll through individual parameters. Service Menu Parameter Guide

While official documentation is sparse, enthusiast testing has identified several key alignment settings within this menu:

bfC: Adjusts the frequency of the 10.24MHz BFO (Beat Frequency Oscillator). This is a critical adjustment for ensuring the radio is centered on frequency in SSB modes.

fr0, fr4, fr5, fr9: These correspond to voltage limit settings for fine-tuning at specific frequency increments (.00, .04, .05, and .09). They control the varicaps to ensure smooth frequency steps.

loC: Controls the local oscillator offset. Experts suggest adjusting lo first to get as close to the target frequency as possible before using bf for final tiny tweaks.

Modulation (IC9): In newer versions or related "Plus" models, navigating to the IC9 setting allows you to increase modulation levels (often defaulted to 31) up to 63 for stronger transmit audio. Standard User Menu vs. Service Menu

For daily operation, you should use the standard Background Function Menu rather than the service menu to avoid accidentally de-aligning the radio. Enter User Menu: Long-press MENU for 2 seconds.

Common Settings: You can adjust Squelch (SQ) levels from 1-36, toggle ECHO functions, or set SWR Protection.

Frequency Expansion: The radio can be expanded via software to cover 25.615–30.105MHz. Shopping Options for the AT-5555N II
