Here is just one of the many question-answers that we have on our Marine Electronics FAQ page.
Q: I’ve been looking at a new VHF radio and noticed that the transmitter specifications say 25/1 watt power. Why are there two power ratings, and are all radios the same?
A: All fixed mount (non-portable) marine VHF radios have high and low power modes of 25 and 1 watt. FCC regulations limit the maximum transmit power to 25 watts and restrict transmit power to 1 watt on certain channels.
