```Megacycles is the old term for Megahertz. Same same. A megacycle is one million cycles per second. As frequency goes up wavelength goes down. Cycles or hertz is the number of events per second, while wavelength is the length of one wave of electrical energy at a given frequency in free space. For example, the forty meter (wavelength) amateur band is 7 Mhz. The twenty meter band is 14 Mhz. The wavelength numbers are only approximations.

The conversion from frequency to wavelength is: 300 divided by the frequency in Mhz equals the wavelength in meters.

300/7 = 42.86 meters     300/14 = 21.43 meters.

For the examples you gave,  50 Mhz (or megacycles) is 6 meters, 165 Mhz is 1.81 meters.

Hope that helps.

Im fairly new at this so here goes a question , What do mc (megacycles)
relate to in terms of Frequency and Bands? Ie... 50-165mc is what freq.?
and how do you get there ?Phil KI6LEA
