What it means on the air: Digital modes often require reduced power because their high average duty cycle heats transmitter finals and antenna components more continuously than normal SSB voice.
Why operators use it
A clean 30-watt data signal can outperform a distorted 100-watt signal, especially in narrow weak-signal modes where decoding gain is already substantial.
Where the contact goes wrong
Using speech compression, heavy ALC, or maximum audio drive spreads energy outside the intended waveform and increases heat without producing a proportional communication gain.
A cleaner operating method
Disable speech processing, set a clean audio level, begin with modest RF power, use only what closes the path, and respect every component’s data-mode power and time rating.
Operating boundary
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.
