FCC Technician Exam Question Of The Day (T1B05)

Q) Which 70 cm frequency is authorized to a Technician Class license holder operating in ITU Region 2?

A) 443.350 MHz

NJ2X Note:
Remember there is an inverse relationship between frequency and wavelength.

Wavelength (meters) = 300 / frequency (Mhz)

For this question:
  • Wavelength (meters) = 300 / 443.350 = 0.676 meters
  • A wavelength of 0.676 m (67.6 cm)  is close to the wavelength to 70 cm (or 0.700 m).
