Do you have a question about the Yaesu FC-902 and is the answer not in the manual?
Capacitive adjustment of coupling between transmitter and impedance. Adjusted for minimum SWR.
Selects inductance for matching. DIRECT position bypasses circuitry.
Calibrates the SWR meter for accurate readings by adjusting meter deflection.
Adjusts coupling between antenna feedline and impedance presented by the BAND switch inductor.
Selects one of three coax-fed antennas or a single wire antenna for matching.
Selects meter sensitivity for power and calibrates SWR measurement.
Reads output power on three scales: 25W, 250W, and 500W.
Provides accurate SWR measurement when calibrated for adjusting controls.
Three female UHF-type connectors for coaxial feedlines or dummy loads.
Threaded terminal for single-wire antennas like the "Windom" type.
Connects to good earth ground for stray currents and RF reduction.
UHF receptacle for connection between FC-902 and transmitter/transceiver.
Emphasizes not exceeding maximum time limits during tune-up, especially at full power.
Shack matching doesn't affect losses on the coaxial line to the antenna.
FC-902 ensures 50 ohm load for protection against high SWR.
Suggests recording TUNE/LOAD positions for specific antennas for quick reference.
