The letter "A" indicates simplex use of the ship station transmit side of an international
duplex channel, and that operations are different than international operations on that
channel. "A" channels are generally only used in the USA, and use is normally not
recognized or allowed outside the USA.
The letter "B" indicates simplex use of the coast station transmit side of an international
duplex channel. The USA does not currently use "B" channels for simplex communications
in this band.
