At the 1 watt setting, who knows?

For the sake of discussions, let's say on a clear day from my VHF
antenna, which is approximately 14' above the waterline, a 25 watt
transmission reaches someone 12 miles away with a similar antenna height.

Is there a way to figure how far a 1 watt setting will reach with the
same equipment?


Don't know how to calculate that...but in our VHF course we were advised
to use the 1 watt when in a small harbour or at an anchorage. The idea
was that 25 watt was overkill in this situation and would add to the
clutter for people a fair distance away.

Crap clutter Don where in the Harbor, as many wats as you want. Harry
your 1 watt is good for boats that are around you and probably not much
more, the 25 will almost get you to Washington and the Bush minions.
