FCC Technician Exam Question Of The Day (T1B07)

Q) What amateur band are you using if you are transmitting on 223.50 MHz?

A) 1.25 meter band

NJ2X Note:
You can memorize this answer.  Alternatively, you can learn and apply the underling theory which will help you beyond the test.  The relationship between a radio signal's frequency and its wavelength is described by the following formula:

wavelength in meters = 300 / frequency in MHz

In the example above, wavelength = 1.34m = 300 / 223.50Mhz.  On the test, the closest answer to the calculated wavelength is the 1.25m band.
