Introduction
The SKANTI VHF 1000 DSC is the new VHF radio for merchant
vessels, fishing ships and other professional users. The SKANTI
VHF 1000 DSC fulfils the latest requirements for VHF and DSC
(digital selective calling function) Class A, and is thus ideal for safe
communication.
The SKANTI VHF 1000 is a professional VHF and an advanced DSC
unit (Class A) integrated in one compact unit, which is ideal for
vessels with limited space for multi-unit configurations. The integra-
tion of the VHF and the DSC functionality ensures simple and logical
operation of the mandatory VHF and DSC GMDSS equipment.
The ergonomic control unit (CU 1000) with an easily legible graphic
LCD display ensures all-time operation. The back-lit “easy-touch”
keyboard makes operation extremely easy even during night time.
The user-friendliness of the operational software facilitates the use of
the two functions: VHF and DSC, which are integrated into one unit.
The control unit includes a built-in loudspeaker of 4 watt and the
important DSC distress button, which is covered by a hatch for the
prevention of unintentional activation. The ergonomically correct
handset is integrated in the control unit securing a complete VHF/
DSC communication platform.
For easy installation the control unit is mounted on the compact
VHF/DSC transceiver unit which has an output power of 25 watt,
thus being able to reach all VHF stations within 40-50 nautical miles.
The VHF includes a SPARC-bus interface. This advanced interface
enables the VHF 1000 DSC to be remote-controlled from handsets
placed e.g. on the bridge wings.
The distance between the transceiver unit and the handset control
unit may be up to 50 metres in 12V DC installations; in 24V DC
installations the distance may be up to 100 metres. An external
loudspeaker may be connected directly to the handset control unit.

VHF Fundamental Info
The VHF Channel System
The VHF radio telephony system uses a limited number of frequen-
cies called channels. The public system has 57 channels, numbered
CH 1 to 28 and 60 to 88, each of which has a certain purpose:
intership, ship-to-port, or ship-to shore (public). You can have private
channels, too. In US waters, the channels are different. Therefore
you need to set the system to “US” channels there. Other waters like
the Rhine have their own different systems, too.
Four channels have special purposes:
16: To be used for verbal distress calls and for calling “all
stations”
only
. All large ships are obliged to monitor it
constantly. Never to be used for chatting, etc.!
70: The DSC channel, see below.
75-76: Used as Guard Band for distress channel 16.
Verbal VHF Communication
All channels except channel 70 are used for verbal communication.
There are two types of channels, simplex and duplex:
- On a simplex channel, both parties transmit and receive on the
same frequency. Therefore you cannot talk and listen at the
same time. When you have finished talking, say “over”, and
release the handset’s PTT key.
- On a duplex channel, you talk and listen on two different
frequencies. You can therefore speak and listen at the same
time. To save power, release the handset’s PTT key except when
talking.
Note that everybody with a VHF receiver can listen to your conversa-
tion, but it is forbidden to use or pass on what is heard.
DSC Digital Communication
DSC is a digital data transfer system using VHF CH 70. The
transmitter waits until the channel is free and then sends its data,
either to a designated address, or to “all stations” for example for a
DSC distress call. It is mainly used for getting in contact in order to
establish verbal communication.
