Using Digital Selective Calling (DSC) Features

What is DSC?

Digital.Selective.Calling.or.DSC.is.a.standard.that.allows.you.to.call.other.
stations using their unique identification code (the Maritime Mobile Service
Identity.or.MMSI.number),.just.like.you.would.call.a.phone.number..To.call.
another.station,.just.enter.that.station's.MMSI.number.and.choose.the.
voice.channel.you.want.to.talk.on..The.radio.uses.channel.70.to.transmit.
your.MMSI.number.to.the.other.station.along.with.the.voice.channel.you.
requested..If.the.other.station.accepts.your.call,.both.radios.automatically.
switch.to.the.requested.voice.channel.so.you.can.talk.to.the.other.station.
DSC.provides.a.system.for.automated.distress.calls..At.the.touch.of.a.
button,.the.radio.can.transmit.your.MMSI.number,.the.nature.of.your.
distress,.and.your.current.position.based.on.data.from.your.GPS.receiver..
The.radio.repeats.the.distress.call.every.few.minutes.until.it.receives.an.
acknowledgement.
The.DSC.standard.dedicates.a.VHF.channel—channel.70—to.digital.
transmissions.only..Since.digital.transmissions.require.less.bandwidth.voice.
transmissions,.channel.70.avoids.the.problems.of.busy.voice.channels.
