سؤال 89

What procedure may be used by Volunteer Monitors to localize a station whose continuous carrier is holding a repeater on in their area?

  1. Compare vertical and horizontal signal strengths on the input frequency
  2. Compare beam headings on the repeater input from their home locations with that of other Volunteer Monitorsپاسخ درست
  3. Compare signal strengths between the input and output of the repeater
  4. All these choices are correct

توضیح

A carrier that holds a repeater open is reaching the repeater's input, so monitors listen on the input frequency and take beam headings on it from several separated locations. Plotting and intersecting those bearings fixes the transmitter; the repeater output tells you nothing about where the offender is.
