1) Promulgate regulations

2) Impose license conditions

3) Ensure International and Regional co-operation

4) All of the above

2) The purpose of using three wires in the power cord from the mains power plug into your amateur radio equipment is to:

1) make it inconvenient to use

2) Prevent the radio chassis from becoming live in the case of an internal short to that chassis

3) Prevent the plug from being reversed in the wall socket

4) Prevent short circuits

3) If 120 v is measured across a 470-ohm resistor, approximately how much Current is flowing through the Resistor?

1) 56,4 A

2) 5,64 A

3) 3,92 A

4) 0,255 A

4) The resistance value of 1200 Ω can be expressed as :

1) 12 kΩ

2) 1,2 kΩ

3) 1,2MΩ

4) 0,12 MΩ

5) Define a Simplex transmission,

1) Where an operator transmits and receives on the same frequency.

2) Where an operator transmits on one frequency and Receives on another frequency.

3) Where transmit and receive frequencies are separated by an Offset.

6) What could happen to your transceiver if you replace a blown 5 amp AC line fuse with a 30 amp fuse?

1) A 50 amp fuse would better protect your transceiver from using too much current

2) The transceiver would run cooler

3) The transceiver could use more current the 5 amps and a fire may occur
