According to FCC rules, who is responsible for ensuring that an amateur radio station complies with RF exposure limits?
Answer: The licensed amateur radio operator controlling the station
The licensee is solely responsible for ensuring their station operates within permissible RF exposure limits.
What does 'time averaging' allow an operator to do when evaluating RF exposure compliance?
Answer: Average high-power transmit periods with low-power or no-transmit periods to remain within MPE limits
Time averaging lets operators mix transmit and non-transmit (or lower-power) intervals so the average exposure stays within the MPE limit over the averaging period.
What is the safest way to discharge a large electrolytic capacitor before working on equipment?
Answer: Remove power and let it discharge through the circuit over several minutes, then verify with a meter
The safe method is to remove power, allow natural discharge through the circuit, and confirm zero voltage with a meter before touching anything.
When is it acceptable to work alone on a tall antenna tower?
Answer: It is never recommended — a ground person should always be present
A ground person is always required to call for help in an emergency, assist with equipment, and maintain a watch.
What precaution should be taken before connecting an antenna to a transceiver that has been stored for several years?
Answer: Inspect all coax connectors, cables, and the antenna itself for corrosion, damage, or water intrusion before operating
Long-stored equipment and cables can develop dangerous faults due to corrosion or degraded insulation that must be inspected before use.
What is the purpose of placing warning signs near a transmitting antenna installation?
Answer: To warn uninformed persons of potential RF exposure so they can maintain safe distance
Warning signs alert people who may be unaware of RF hazards so they can avoid close proximity to a transmitting antenna.
Which condition makes a ladder the most dangerous tool for tower work?
Answer: Leaning the ladder against the tower while a second person climbs the tower independently
Simultaneous ladder and tower climbing can cause vibrations or shifts that destabilize both climbers; only one person should be on a structure at a time.
