Abstract: A mobile device sends to a radio communicatively coupled to the mobile device, an instruction to monitor a frequency band. It is determined that the frequency band is jammed by a jamming source. The mobile device receives, from the radio, signal waveform information corresponding to the frequency band that is received by the radio from a 360 span about the radio. Based on the waveform information a direction of the jamming source is determined. The mobile device presents on a display device information that indicates that the frequency band is being jammed, and a direction of the jamming source with respect to a current location of the radio.
