§  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 § 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.
