On which of the following HF frequencies can automatically controlled amateur propagation beacons be found?
Anywhere in the Technician portion of 10 meters
Anywhere, if they are registered with the FCC
In a specific portion of each of the HF Technician bands
On ten meters, between 28.200 MHz and 28.300 MHz✓Ճիշտ պատասխան
Բացատրություն
Only a narrow slice of 10 meters is available for beacons running under automatic control, so beacons are not scattered across the Technician bands and no FCC registration changes that. Note the frequency segment is fixed by rule, not by band plan.
