Ham Radio General Class Practice Test

Which of the following applies in the event of interference between a coordinated repeater and an uncoordinated repeater?

1. The licensee of the non-coordinated repeater has primary responsibility to resolve the interference

2. The licensee of the coordinated repeater has primary responsibility to resolve the interference

3. Both repeater licensees share equal responsibility to resolve the interference

4. The frequency coordinator bears primary responsibility to resolve the interference

The correct answer is: The licensee of the non-coordinated repeater has primary responsibility to resolve the interference

The scenario described involves a coordinated repeater, which operates on frequencies designated by a frequency coordination organization, and an uncoordinated repeater that does not have such designation. In cases of interference, the licensee of the non-coordinated repeater holds primary responsibility for resolving that interference. This is due to the principle that coordinated repeaters are operated under established guidelines and are expected to follow protocols that minimize interference with other coordinated users. In contrast, uncoordinated repeaters do not adhere to these protocols, which can lead to interference that disrupts the operations of the coordinated system. Therefore, it falls upon the operator of the uncoordinated repeater to address the issue and mitigate interference to comply with the expectations of good amateur radio practice. This division of responsibility helps maintain order and allows for effective use of the shared spectrum, ensuring that coordinated repeaters can operate efficiently without disruption from those that haven’t gone through the proper channels for frequency coordination.
