Anytone At5555n Ii Service Menu Work 2021 Jun 2026

Lower the value until your meter registers exactly with the radio's physical power knob turned all the way down.

These values regulate the drive levels for the final amplifier stage. They are typically split by mode: : Sets the maximum carrier output.

Press and hold the FUNC button or turn the radio off and back on to commit the new settings to the permanent memory. Critical Warnings Before Making Adjustments

If the clarifier doesn't move smoothly, check the service menu steps for the clarification adjustments. anytone at5555n ii service menu work

Create a spreadsheet or notebook of your baseline values. If a setting makes the radio perform worse, you need a reliable way to get back to "factory standard."

Sets the maximum width of the FM signal (typically limited to 2.5 kHz for narrow or 5.0 kHz for wide FM).

You can tweak how wide the signal swings in FM mode. Turning this up slightly can help you punch through heavy QRM (interference), but pushing it too high will cause over-modulation and splatter onto adjacent frequencies. Lower the value until your meter registers exactly

These settings dictate the fine-tuning limits of the radio's synthesizer. The radio fine-tunes itself by adjusting the voltage across a set of varicaps, which affects the capacitance and alters the frequency of the oscillator.

If Single Sideband (USB/LSB) signals sound distorted or require you to ride the clarifier constantly, your BFO values need calibration:

Adjusts the power output specifically for USB and LSB modes. 2. Modulation Adjustments Press and hold the FUNC button or turn

While specific numbers may vary slightly by firmware version, common adjustments identified by users include: AM High Power

Factory settings are unique to each individual radio because they are calibrated during production.

Adjusts how the Clarifier (RIT/XIT) operates. 4. Noise Blanker (NB) and Squelch

💡 Most people only need it to slightly lower dead key power for an amplifier, or to fix slightly off-frequency SSB transmit. If the radio is working fine – don’t touch it. Seriously.
