MF/HF transceiver power levels should be set:

Setting MF/HF transceiver power levels to the lowest level necessary for effective communications is essential for several reasons. Firstly, using minimal power reduces the risk of causing interference to other stations and contributes to responsible and efficient use of the radio spectrum. This practice aligns with the concept of "doing more with less," where operators aim to establish reliable communication without overextending their power usage unnecessarily.

Additionally, lower power settings can lead to better battery conservation and enhance the operational life of equipment, especially in portable or emergency situations. It also allows for more effective sharing of frequencies, as higher power levels can result in congestion and limit accessibility for other users.

While maximizing the propagation radius or using the highest power possible might seem beneficial in certain scenarios, they do not align with the principle of minimizing interference and conserving resources. Thus, the most responsible and effective approach is to use just enough power to maintain clear and stable communication.
