Sec. 80.753  Signal strength requirements at the service area contour.

    (a) The requirements for reception by a marine VHF shipboard 
receiver are satisfied if the field strength from the coast station, 
calculated in accordance with Sec. 80.771 is at least +17 dBu above one 
microvolt.
    (b) These field strengths, voltages and powers at the receiver input 
are equivalent:
    (1) -132 dBW (decibels referred to 1 watt).
    (2) 1.8 microvolts across 50 ohms.
    (3) +17 dBu (decibels referred to 1 microvolt per meter).
    (4) 7 microvolts per meter.
