If a frequency readout calibrated in megahertz shows a reading of 3.525 MHz, what would it show if it were calibrated in kilohertz?

If a frequency readout calibrated in megahertz shows a reading of 3.525 MHz, what would it show if it were calibrated in kilohertz?

• A. 0.003525 kHz
• B. 35.25 kHz
• C. 3525 kHz
• D. 3,525,000 kHz

Answer: (C)

When converting frequencies between megahertz (MHz) and kilohertz (kHz), it’s essential to remember the relationships between these units. One megahertz is equal to 1,000 kilohertz. Therefore, to convert a frequency from megahertz to kilohertz, you multiply the megahertz value by 1,000. In this case, the given frequency is 3.525 MHz. To convert this to kilohertz, you take: 3.525 MHz * 1,000 = 3,525 kHz. Thus, when calibrated in kilohertz, a frequency of 3.525 MHz displays as 3,525 kHz. This understanding reflects a correct grasp of unit conversion in radio communications, which is crucial for operating ham radio equipment.
