Question

What is the wide band receive coverage of the Yaesu FT-70DR?

a) 100 kHz to 1 MHz
b) 1 MHz to 30 MHz
c) 30 MHz to 470 MHz
d) 470 MHz to 800 MHz

Answer 1

The Yaesu FT-70DR has a wideband receive coverage from 30 MHz to 470 MHz, encompassing VHF and lower UHF ranges.

Step-by-step explanation:

The wideband receive coverage of the Yaesu FT-70DR is c) 30 MHz to 470 MHz. This range includes both the Very High Frequency (VHF) and the lower portion of the Ultra-High Frequency (UHF) spectra, which are commonly used for various communication services, including amateur radio, commercial radio, and public service broadcasts.

The AM radio frequency range of 540 to 1600 kHz corresponds to wavelengths ranging from about 555.6 meters to 187.5 meters. As for FM radio, whose frequency range is 88.0 to 108 MHz, the wavelength range is approximately from 3.41 meters to 2.78 meters, based on the relationship between frequency and wavelength that wavelength is the speed of light divided by frequency.
