SMR1 Multiple Band Scanning Receiver for Law Enforcement and Surveillance

The SMR1 multiple band scanning receiver is a useful tool for detecting frequency band usage. The SMR1 receiver scans up to 3 frequency bands (one at a time) in 1 MHz steps and reports the frequency and level via a serial output.

The SMR1 offers many useful features such as user configurable Offset/Correction Factor, Reporting Threshold, Start/Stop Sub-Bands, and Single or Continuous Sweeps.

SMR1 receivers are ideal for law enforcement, surveillance, and other applications needing a useful tool to detect frequency band usage in a given area.
