Radio interference is a common problem for both radio operators and your neighbours. Sometimes it is caused by the radio operator. Sometimes it is caused by your neighbour. In either case the problem needs to be fixed. Once you understand the different types of interference it is usually fairly easy to identify the cause and implement a fix.
This section of the course has a technical focus and there are a number of new terms. If you go through the material slowly and systematically, underlining the terms, and writing the definitions on a sheet of paper, you will remember the material when you review the questions in the question bank.
The Question Bank
About 5% of the exam questions will be from section B-008 in the question bank. There are about 50 questions to review. They are found in the following sections:
Interference and Suppression - 008 8-1 front-end overload, cross-modulation 8-2 audio rectification, bypass capacitors, ferrites 8-3 intermodulation, spurious, key-clicks 8-4 harmonics, splatter, transmitter adjustments 8-5 use of filters: low-pass, high-pass, band-pass, band-reject
The Study Guide
Chapter 15 in the Study Guide covers the material in 11 pages. It should take about an hour to read through this. After reading the material try all the questions in Section B-008 of the question bank. Keep track of the questions you got wrong and go back and review Chapter 15 again.
Your instructor will demonstrate some devices used to eliminate or reduce radio interference.
