Use and safety guidelines

Last updated October 26, 2026

Signal Lab is an experimental tool operated by TGthms for learning about audio signals, data transmission, Morse and EAS/SAME. These guidelines explain the app’s intended use and important safety limits.

Not an emergency service

Signal Lab is not an emergency alerting service or certified EAS equipment. Do not use it to issue public warnings or make safety-critical or emergency decisions. It is not affiliated with or endorsed by a government agency, broadcaster or standards body. Use official sources for actual emergency information.

Responsible use

You are responsible for your use of the app and for complying with the laws that apply to you. Do not use Signal Lab to mislead or frighten people, cause panic, impersonate an authority, interfere with alert systems, or transmit false or unauthorized alerts.

In the United States, 47 CFR § 11.45 restricts transmission of EAS codes and attention signals, including recordings and simulations, except as permitted by the rules. A test label or educational purpose does not by itself authorize use. Rules may differ elsewhere. Prefer the silent decoder test and keep tones away from broadcasts, livestreams, public-address systems and alert equipment unless use is authorized.

Limits and privacy

Signals can be corrupted, lost, overheard or misunderstood. Checksums and matching headers do not prove who sent a message. Signal Lab does not encrypt or authenticate messages. Review the privacy notice for information about the app and hosting services.

Availability and outside resources

The app and its information are provided for study without a guarantee of accuracy, availability or fitness for emergency use. Features may change or be discontinued. External resources are maintained by their own providers.
