Basic Info

Question 1

Frequency Allocation

Answer 1

HF - 3 to 30MHz
VHF - 30 to 300MHz
UHF - 300 to 3000MHz

Question 2

Explain primary and secondary allocation

Answer 2

We have to share frequencies
Either primary or secondary
Primary = ok to broadcast (but check first by listening)
Secondary = sharing with others, careful don’t interfere

Question 3

What is the foundation frequency allocation?

Answer 3

144-146MHz

Question 4

Explain: Frequency & Wavelength

Answer 4

Distance of a wave measured from peak to peak is known as a wavelength

As frequency rises the wavelength is reduced

As frequency goes from low to high, wavelength goes from long to short

Question 5

What are the modes?

Answer 5

Modes = the types of data that can be sent.

Voice
Morse (CW)
Data
SSTV (slow scan television)

Question 6

What are the modulations?

Answer 6

The modulations:

FM (frequency modulation)
AM (amplitude modulation)
SSB (single sideband)
