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.
