Hook up the radio to a frequency counter via a dummy load. Transmit a carrier on a known frequency (e.g., 27.005 MHz or 28.000 MHz) in CW or FM mode. Adjust the service menu reference value until the frequency counter reads exactly true. 2. TX Power Output Alignments (AM / FM / SSB)
Recent firmware updates (post-2023) have changed how users access and navigate this hidden diagnostic suite. Welcome to the guide for the AnyTone AT5555N II Service Menu .
Typically set for roughly 12 to 15 watts of carrier power, leaving adequate headroom for audio modulation swing. 3. FM Power Calibration (FM-PWR) Menu Label: FM-P or FPW Purpose: Sets the continuous power output for the FM mode.
Turn the radio ON while holding them. As soon as it powers up, release them and quickly press the other buttons in a line from DW all the way down to EMG . anytone at5555n ii service menu updated
The updated AT-5555N II firmware breaks down the service menu into distinct functional categories. While AnyTone occasionally updates the register layout, the core tuning categories remain consistent. 1. Transmitter Power Calibration (TX Power)
Adjusts the depth of the AM voice modulation. Setting this too high results in clipped, distorted audio; setting it too low yields quiet transmission.
The main menu structure may be affected, as new user menu items can be added, shifting the numbering of existing ones. However, the core service menu remains intact. Hook up the radio to a frequency counter via a dummy load
Press and hold both the FUNC (Function) key and the PUSH (Channel selector encoder) knob simultaneously.
