MF-HF SSB-SITOR

Question 1

Answer 1

Voltage panel indicator lamps may glow with each syllable.

Question 2

What might contribute to apparent low voltage on marine SSB transmitting?

Answer 2

Blown black negative fuse.

Question 3

What type of wire connects an SSB automatic tuner to an insulated backstay?

Answer 3

GTO-15 high-voltage cable.

Question 4

Which of the following statements concerning SITOR communications is true?

Answer 4

ARQ message transmissions are made in data groups consisting of three-character blocks.

Question 5

The sequence ARQ, FEC, SFEC best corresponds to which of the following sequences?
•One-way communications to a single station, one-way communications to all stations, two-way communications.

•Two way communications, one-way communications to a single station, one-way communications to all stations.

•Two way communications, one- way communications to all stations, one-way communications to a single station.

•One-way communications to all stations, two-way communications, one-way communications to a single station.

Answer 5

Two way communications, one-way communications to all stations, one-way communications to a single statio

Question 6

Which of the following statements concerning SITOR communications is true?
•Communication is established on the working channel and answerbacks are exchanged before FC broadcasts can be received.

•In the ARQ mode each character is transmitted twice.

•Weather broadcasts cannot be made in FEC because sending each character twice would cause the broadcast to be prohibitively long.

•Two-way communication with the coast radio station using FEC is not necessary to be able to receive the broadcasts.

Answer 6

Two-way communication with the coast radio station using FC is not necessary to be able to receive the broadcasts.
