## Overview

规划与校验业余无线电发射。按 IARU 区域找频段边界(如 R1 的 40 米为 7.0–7.2,R2/R3 为 7.0–7.3),显示模式分段、FT8 频率、边带,并按美国/中国执照等级校验权限与功率。中国 B类 HF 限 15W(2024 新规),2米为 144–146。数据来源:IARU/ARRL/CRAC。

## Inputs

- **Frequency (MHz)** (number): e.g. 14.074
- **IARU Region** (select)
- **Country / License Rules** (select)
- **US License Class** (select)
- **China License Class** (select)
- **Antenna Unit** (select)

## When to use

- Check whether a planned transmit frequency falls inside the selected IARU region band.
- Verify US or China license-class privileges before operating on a frequency.
- Plan FT8, SSB, or antenna settings for a specific amateur radio frequency.

## How it works

- Enter a transmit frequency in MHz, such as 14.074 or 7.153.
- Select an IARU region and, if needed, a country and license class.
- The tool identifies the band edges, mode segments, FT8 frequency, sideband, and dipole length.
- Choose feet or meters for the dipole-length result and review the privilege or power check.

## Use cases

- Amateur operators can validate a frequency before transmitting within the selected regional band plan.
- FT8 operators can compare an entered frequency with the listed FT8 dial frequency and review the related band details.
- Radio clubs and instructors can demonstrate how region, license class, mode, sideband, and antenna length relate to a frequency.

## Frequently asked questions

### What frequency units does the tool use?

Enter the transmit frequency in MHz, with precision supported to 0.001 MHz.

### Which IARU regions are supported?

The tool supports Region 1 for Europe, Africa, and the Middle East; Region 2 for the Americas; and Region 3 for Asia and the Pacific.

### Can it check license privileges?

Yes. It checks selected US FCC or China license classes. You can also choose Other to skip the privilege check.

### Does it show the expected sideband?

Yes. The result includes the sideband associated with the detected frequency and mode segment.

### What antenna measurement units are available?

Dipole length can be displayed in feet using 468/f or in meters using 142.5/f.
