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


Sometimes 1 watt will get you 10 miles. It depends a LOT on the condition
of your antenna system and the other guy's corroded up old piece of crap
with the rotten coax, seized connectors, all full of rain/seawater in the
bilge hooked up, eventually after those 3 kinks where he screwed the
wallboard in too hard, to that corroded up old Standard he moved over from
his center console fishing boat.

Because his radio system hasn't been properly maintained or tested in
years, and he's too naive to know any better or care, better leave it on 25
watts and hope he hears you through the noise of his buzzing inverter and
those loose, corroded connections in the 12V breaker panel that never got
cleaned, either.

Assume the worst, run the power, then after you've gotten him to respond,
switch power levels to 1W and see if he still responds or starts telling
you you're noisy. Of course, this all assumes he can hear you over
Smiley's Marina and Raw Bar running 25 watts from Smiley's 70' tower over
the office talking to the boat on his gas dock that's so close he can read
the date on the DNR license tag, jamming boat radios for 40 miles in all
directions....(sigh)
