Plain-language answer: Duty cycle is the proportion of time a transmitter or component carries power during a stated interval.
Why operators care
Long transmissions and constant-envelope modes can create much more average heating than intermittent voice even when peak power is identical.
Set it up correctly
Use the manufacturer’s time interval and mode rating, include ambient temperature and ventilation, and reduce power or transmit time when the system heats excessively.
The common mistake
Comparing only peak watts while ignoring how long the transmitter stays keyed.
Operating boundary
Current regulations, service documentation, satellite status, software versions, and the complete station’s continuous-duty limits control. Online reports are observations, not guaranteed link performance.
