App will not open
Restart the device, confirm Android 7.0 or later, verify adequate local storage, and reinstall only from the publisher's authorized distribution.
Troubleshooting
Support and local controls
Signal Bench has no account, cloud service, remote support session, or server copy of your progress.
Progress looks different
Reviewed-card markers and the preset-practice stage live only in app-private preferences on this device. A reset, storage clear, or reinstall removes them.
Reset local state
Open Reset and delete from the Workbench or Privacy Center. This clears local reviewed-card and practice-stage preferences; there is no server copy to delete.
No signal or hardware connection
Expected: the app cannot transmit, receive, scan, tune, discover, or control radio equipment and requests no Bluetooth, microphone, location, or Internet permission.
Rules or safety question
Use the Source Drawer, current FCC/eCFR material, exact equipment manuals, site requirements, and a qualified person. Do not rely on an offline card for consequential work.
Accessibility
Use Android text-size and display settings as needed. Website motion can be reduced with the operating system's Reduce Motion preference.
Privacy correspondence
Mail correspondence to Heard County Radio Club Inc., PO Box 115, Franklin, GA 30217-0115, United States. Include “Signal Bench” so the request can be routed appropriately. Do not send passwords, callsigns, health details, incident reports, or other sensitive records.
Urgent help
This support page is not monitored as an emergency service. Signal Bench cannot contact responders. In an urgent situation, leave danger when possible and use established local emergency services.
