E2C07

What is the Cabrillo format?

  1. A standard for organizing information in contest log files

E2C08

Why are received spread-spectrum signals resistant to interference?

  1. Signals not using the spectrum-spreading algorithm are suppressed in the receiver

How does the spread-spectrum technique of frequency hopping (FH) work?

  1. The frequency of the transmitted signal is changed very rapidly according to a particular sequence also used by the receiving station

E2C10

Why might a phone DX station state that he is listening on another frequency?

  1. A. Because the DX station may be transmitting on a frequency that is prohibited to some responding stations
