Two way radio audio feeds

Online scanner feeds for many locations are available from Broadcastify, and can be listened to directly using a web browser. These feeds are also available through a variety of iPhone and Android apps, such as Scanner911. Some agencies are also making feeds available through walkie talkie apps such as Zello. Bloomington area feeds are available on Zello - particularly BTN FIRE/EMS has feeds of fire and EMS dispatch and fireground channels, and BTN HOTCALL has mutual aid hotcalls from police and other agencies.

Incident paging

There are a variety of services available that have volunteers that send out pages (to email or by text message) for incidents in a particular geographic area. Whether or not you get a page for an incident can be sporadic based on whether the incident is picked up by a volunteer. The main paging services are IPN Paging, USEmergAlerts, AlertPage, and 1st Responder Wireless News. IPN alerts are put out (delayed) on Broadcastify county pages (see e.g. Monroe County).
