Moving from 25W to 50W doubles transmitter power, but it adds only about 3 dB to the outgoing signal, not twice the range. A 65W setting adds about 4.15 dB over 25W and only about 1.14 dB over 50W, so the practical difference depends on the antenna system, terrain, feedline loss, supply voltage, receiver conditions, … Read more
