Ham Radio ID Timer

What it does

A compliance tool for Amateur Radio operators to meet FCC Part 97 rules, which require station identification every 10 minutes during communications.

Features & Controls

• Ease of Control: Press the Spacebar or Enter key to instantly start the timer, or reset the clock back to 10:00 after you identify.
• Saved Settings: Your audio alert preferences are automatically saved in your browser.
