Abstract

We describe the calibration of an inexpensive, reliable system for use in weak-signal detection. The calibration procedure described allows the conversion of signals measured with the communications receiver system-which is based on a standard communications receiver and a personal computer sound card-to-electric field values. This enables the use of the system for system-independent propagation studies. In addition, the system allows detection of signals ont he order of 20-30dB lower than is possible with standard handheld radio. This is of great use to the public safety community.
