9. Selecting the
Transmit Power
By law, Marine VHF radios must be able
to transmit at 1 watt power as well as the
radio’s maximum transmit power. The
West Marine VHF200 radio actually has
three transmit powers: 5 watts (HI), 1
watt (MED), and 0.5 watts (LOW).
The general rule is to use the lowest
transmit power that results in clear com-
munications with whomever you are com-
municating. At distances less than a mile,
for example, 0.5 watts may result in clear
and consistent communications, and will
have the benefit of greatly extended bat-
tery life.
Pressing the H/L key will change the
transmit power from 5 watts (HI) to 1
watt (MED) to 0.5 watts (LOW) and back
to 5 watts with each press. The Radio
Status Display will indicate the newly
selected transmit power as follows:
• When High Power is selected, the
bottom of the screen will Radio
