GMDSS. FCC Test 60 – Online Maritime Tests

Which would indicate a malfunction in a 2182 kHz radiotelephone system?

Dramatic decrease in noise level observed during night and early morning hours.
No discernable traffic has been heard on the 2182 kHz during the radiotelephone silent periods.
Failure to contact another station 60 miles distant during daytime operation.
The visual indication of power to the antenna fluctuates while testing the radiotelephone alarm signal generator into an artificial antenna.

What would be an indication of a malfunction on a GMDSS station with a 24 VDC battery system?

None of the above.
After testing the station on battery power, a voltmeter reading of 30 volts for brief period followed by a steady 26 volt reading.
A constant 30 volt reading on the GMDSS console voltmeter.
After testing the station on battery power, the ammeter reading indicates a high rate of charge that then declines.

There are no signals or static heard in the receiver of the SSB Transceiver, although a loud noise is heard if the volume control is advanced all the way up, what is a possible cause?

The antenna or feedline has been damaged.
The antenna switch has been transferred to the test position.
Any of these.
A defective receiver.

Which would be an indication of proper operation of a SSB transmitter rated at 60 watt PEP output?

In SSB (J3E) voice mode, with the transmitter keyed but without speaking into the microphone, power output is indicated.
In Sitor communications, the power meter can be seen fluctuating regularly from zero to the 60 watt relative output reading.
A steady indication of transmitted energy on an RF Power meter with no fluctuations when speaking into the microphone.
In SSB (J3E) mode, speaking into the microphone causes power meter to fluctuate slightly around the 60 watt reading.

How often does a coast radio station that regularly broadcasts traffic lists transmit the list?

As often as is deemed necessary to effect delivery.
Once per 24-hour period.
Only on an as-needed basis.
No less often than every four hours.

Which of the following conditions would be a symptom of malfunction in a 2182 kHz radiotelephone system which must be reported to an onboard or at-sea maintainer under GMDSS?

No indication of power output when speaking into the microphone.
Failure to contact a shore station 600 nautical miles distant during daytime operation.
When testing a radiotelephone alarm on 2182 kHz into an artificial antenna, the distress frequency watch receiver becomes unmuted, an improper testing procedure.
Much higher noise level observed during daytime operation.

What message charges are incurred when sending a ship?s business message through a public correspondence station?

Ship station (SS), coast (CC), and land line (LL) charges.
Ship station (SS) and coast (CC) charges.
Coast (CC) and land line (LL) charges.
Ship station (SS) and land line (LL) charges.

What is an accounting authority?

An agency responsible for establishing tariff rates for commercial communications.
An agency responsible for verifying the accuracy of a shipping company's financial records.
An agency responsible for settling a vessel's financial accounts for chargeable communications.
An agency responsible for collecting payments on behalf of a vessel.

Which would indicate proper operation of a SSB transmitter rated at 60 Watt PEP output in J3E mode?

In SITOR communications, the power meter can be seen fluctuating regularly from zero to the 60 watt relative output reading.
In SSB (J3E) mode, speaking into the microphone causes the power meter to fluctuate well above the 60 watt reading.
A steady indication of transmitted energy on an RF power meter with no fluctuations when speaking into the microphone.
In SSB (J3E) voice mode, with the transmitter keyed but without speaking into the microphone, no power output is indicated.

What are the primary components of a formal message or cable sent from a vessel to a coast radio station for delivery?

Service instructions, address, text, and signature.
Date/time group, address, text, and signature.
Preamble, service instructions, address, text, and signature.
Preamble, address, text, and signature.
