To ensure the reference oscillator is accurate.
If a radio appears to be off-frequency or the power output is inconsistent, it should be checked using professional tools, including: To monitor modulation quality and ensure no spurious
The AnyTone AT-5555N II is a powerful, high-performance 10-meter radio that has gained massive popularity among hobbyists for its high output and flexibility. While the standard settings menu covers most day-to-day needs, many advanced users look for the "Service Menu" (or Hidden Menu) to fine-tune the radio's hardware performance, such as power output levels and modulation depth. Understanding the Service Menu
Adjusting power output levels or modulation depth beyond factory specifications can cause the final power transistors to overheat and fail. To ensure the reference oscillator is accurate
Instead of accessing the service menu, most users can optimize their AnyTone AT-5555N II experience through standard operations:
