VHF-UHF EMI Source Tracking Experiments

Electromagnetic interference source tracking experiments are described using hand-held directional antennas and various detectors at 144 MHz and 432 MHz. The collapsible antennas may be scaled to other VHF-UHF frequencies. All equipment is portable and low cost, and includes commercial VHF-UHF hand-held transceivers, the nanoVNA, and tinySA.
