Most videos tell us the frequency used in bands, which band is for CD, so forth, but I have found no video explaining how to choose one band over another depending on what the operator needs to do. I would love that video.

All radio waves travel at the speed of light, so they all travel the same distance in one second. Now visualize that as it travels that distance, a high frequency wave is cycling many times, and a low frequency wave is cycling fewer times. So the higher frequency has a shorter wavelength; that's how it can pack more cycles into its trip. Frequency and wavelength are two different but forever linked ways of looking at the same radio signal. Bands are the chunks of frequency spectrum that the authorities have designated for different uses. And because frequency and wavelength are always linked, we can define those bands in either way. The "2-meter band" includes a range of frequencies (144 MHz to 148 MHz in the US) that all have wavelengths around 2 meters.

Your post was much more helpful than the video - thank you! But I'm studying for my tech test, and I'd really like to understand the ins and outs of carrier frequency and band edge. Can't seem to find an actual explanation, only things like this spouting chart info.

@@jeanneathon Thank you. I'm studying for my tech license, too, so I'm right with you on trying to get my head around everything. The Craig Buck guide is helpful, but it might be smart to get the ARRA manual, too. Good luck with your process!

Because most Hams are not teachers, it took me month to figure out the relationship between bands and frequencies. Bands are simply groups or sections of frequencies up and down the MHz spectrum. In other words, the FM radio in your car is just one band of frequencies that radio is allowed to play with. As you change channels on your radio, you are moving up or down through that band or group of frequencies. The same is true for AM radio or CB radio. They all are sections of frequencies. Well, Ham radio is no different, EXCEPT ham is allowed to use frequencies on multiple sections or "bands" which are not contiguous (not right next to each other). Most cheaper hand held radios only can access 2 or at most 3 bands, while the more expensive models access many, many bands. I hope that is helpful to someone.

I'm studying for my Technician Ham radio operator license and I'm really having trouble understands Bands & all that . Because I wanna make sure that I'm staying in the proper bands & frequencies that Technicians are allowed to operate in until I eventually go for my General license. I've been looking at the Baofeng Uv-5R HT for my first radio , but now I'm actually looking into the ICOM IC-705 instead because it seems to be a much more capable radio Especially as I start to learn more & begin experimenting with frequencies , bands , DMR & stuff as I'm learning about them

It's all related to the speed of light, or the speed at which electrons can move: 300,000km/s. Hence: 30m band : 300,000,000m/s / 30m = 10,000,000 (cycles) / s = 10MHz. So the 40m band is located around 7.5 MHz (40 x 7.5 = 300), and the 60m band is located around 5 MHz (60 x 5 = 300).

hi, I always get confused when I am told 'all bands above 30mhz' ? So what would be considered below 30mhz ? and Above 30mhz?
