Why operators use it
Average heating and current can be far higher than conversational SSB even when peak output is the same. Radios, tuners, transformers, batteries, and antennas can each impose a different limit.
Where the contact goes wrong
Judging stress only from the front-panel power setting ignores transmit duration, waveform, cooling, mismatch, and ambient temperature.
A cleaner operating method
Calculate the actual transmit pattern, follow the lowest applicable continuous/data rating, reduce power, keep airflow clear, monitor temperature and supply voltage, and pause before thermal protection intervenes.
Use current software and radio documentation, published band plans, applicable licensing rules, and the lowest power that closes the path. A decode, map position, or automated exchange does not by itself prove end-to-end communication.
