• Abstract:
  VHF transceiver tests described in this report were performed at the Volpe National Transportation Systems Center under Federal Aviation Administration (FAA) sponsorship. Laboratory tests were performed on ten different panel-mount type, General Aviation (G/A) class VHF communication transceivers, and two remote-mounted Air Carrier class VHF transceivers. The goal was to measure all radio frequency (RF) emissions from the transceiver antenna port and its case that fall in the Global Positioning System (GPS) Ll band (1575.420±1.023 MHz). These tests were performed to address reported and potential problems involving VHF transceivers interfering with GPS receivers on-board aircraft, particularly in the G/A class.
