47 C.F.R. § 80.753
The requirements for reception by a marine VHF shipboard receiver are satisfied if the field strength from the coast station, calculated in accordance with § 80.771 is at least + 17 dBu above one microvolt.
These field strengths, voltages and powers at the receiver input are equivalent—
−132 dBW (decibels referred to 1 watt).
1.8 microvolts across 50 ohms.
+ 17 dBu (decibels referred to 1 microvolt per meter).
7 microvolts per meter.
