1-B-08: Operating Procedures-1
1-8B1:
What is the best way for a radio operator to minimize or prevent interference to other stations?
Determine that a frequency is not in use by monitoring the frequency before transmitting.
By using an omni-directional antenna pointed away from other stations.
Reducing power to a level that will not affect other on-frequency communications.
By changing frequency when notified that a radiocommunication causes interference.
1-8B2:
Under what circumstances may a coast station using telephony transmit a general call to a group of vessels?
When announcing or preceding the transmission of Distress, Urgency, Safety or other important messages.
Under no circumstances.
When the vessels are located in international waters beyond 12 miles.
When identical traffic is destined for multiple mobile stations within range.
1-8B3:
Who determines when a ship station may transmit routine traffic destined for a coast or government station in the maritime mobile service?
Ship stations must comply with instructions given by the coast or government station.
Shipboard radio officers may transmit traffic when it will not interfere with ongoing radiocommunications.
The order and time of transmission and permissible type of message traffic is decided by the licensed on-duty operator.
The precedence of conventional radiocommunications is determined by FCC and international regulation.
1-8B4:
What is required of a ship station which has established initial contact with another station on 2182 kHz or Ch-16?
The stations must change to an authorized working frequency for the transmission of messages.
The stations must check the radio channel for Distress, Urgency and Safety calls at least once every ten minutes.
Radiated power must be minimized so as not to interfere with other stations needing to use the channel.
To expedite safety communications, the vessels must observe radio silence for two out of every fifteen minutes.
1-8B5:
How does a coast station notify a ship that it has a message for the ship?
The coast station may transmit, at intervals, lists of call signs in alphabetical order for which they have traffic.
By making a directed transmission on 2182 kHz or 156.800 MHz.
The coast station changes to the vessel’s known working frequency.
By establishing communications using the eight-digit maritime mobile service identification.
1-8B6:
What is the priority of communications?
Distress, Urgency and Safety.
Safety, Distress, Urgency and radio direction-finding.
Distress, Safety, radio direction-finding, search and rescue.
