FREE Ham Radio General License Questions and Answers


What results in the periodic variation of HF propagation conditions in a 26- to 28-day cycle?

Correct! Wrong!

The 26- to 28-day cycle of HF propagation conditions is caused by the spinning of the Sun's surface layers around its axis.

What is an electronic keyer used for?

Correct! Wrong!

The automatic creation of dots and dashes for CW operation is the function of an electronic keyer.

What does the "QRN" in the Q signal mean?

Correct! Wrong!

The Q signal "QRN" is used as a question and stands for "noise from natural sources."

Which of the following represents a method of making contact with a gateway station for a digital messaging system?

Correct! Wrong!

Simply transmit a connect message on the station's designated frequency to make contact with a gateway station for the digital messaging system.

The QRP operation is what?

Correct! Wrong!

Low power transmitting is known as QRP operation. Many people favor this style of operation because it calls for extraordinary accuracy and skill. QRP denotes a transmitter output power of no more than 5 watts for Morse code and no more than 10 watts for voice transmission. Most QRP communication takes place on HF and in Morse code.

What is the maximum distance on Earth's surface that can typically be traversed in one hop while using the E region?

Correct! Wrong!

The maximum distance that may often be traversed in one hop using the E area is 1,200 miles along the surface of the Earth. The portion of the ionosphere between 90 and 150 kilometers above the surface of the Earth is referred to as the E area or Kennelly-Heaviside layer. This layer has the ability to reflect medium-frequency radio signals, especially at night when the solar wind is pulling the ionosphere farther from the Earth. The time of year and the amount of sunspot activity also have an impact on how far the E layer can send messages.

NVIS (near vertical incidence skywave) propagation – what is it?

Correct! Wrong!

Short-range MF or HF propagation at steep elevation angles is known as near vertical incidence skywave (NVIS) propagation.
