Which of the following is true concerning access to frequencies?
Nets have priority
QSOs in progress have priority
Except during emergencies, no amateur station has priority access to any frequency✓Ճիշտ պատասխան
Contest operations should yield to non-contest use of frequencies
Բացատրություն
No amateur frequency is assigned for exclusive use, so nets, contests and contacts already in progress all stand equal and none of them can claim a frequency. The single ranking the rules create is priority for stations providing emergency communications.
