Radio Monitoring

This section contains links to resources related to monitoring radio of all bandwidths. If you know about a resource you would like added here, please contact us.

Software-Defined Radio Receiver

Link: www.websdr.org

A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet.

University of Twente: Wide-band WebSDR

Link: websdr.ewi.utwente.nl:8901

On this page you can listen to and control a short-wave receiver located at the amateur radio club ETGD at the University of Twente. In contrast to other web-controlled receivers, this receiver can be tuned by multiple users simultaneously, thanks to the use of Software-Defined Radio.

Antenna Search

Existing Towers: Registered and Non-Registered structures where antennas are placed. Towers may be used for various services including Cellular, Paging, Microwave and others.

Future Towers: Newly filed (or pending) applications to construct new towers. Application info includes location coordinates and detailed ownership data.

Antennas: The actual emitters of radio signals. Antennas can be placed on towers (multiple) or can be installed stand alone on top of existing buildings. Stand alone antennas are small (well below 200 ft). You may also check multiple antennas to determine which cell phone carriers are located on a particular tower.
