Just like we all have our favorite Super Bowl food, we Hams have our favorite bands. The band to chose may be secondary to your favorite, but the key question to ask is “what band or bands will my license allow me to operate on?” From your first day of your licensing process you will learn this. Secondly you need to know what equipment covers what bands. Just cause you have a base station doesn’t mean it will cover HF as well as VHF. We’ll discuss equipment later on in these lessons.
Band Restrictions Besides what band you can use, you also need to take into considerations of any band restrictions based on your license. For example, here in the US all hams can use 10m, however Technicians are limited on how much of the band they can use, along with being restricted to only SSB phone and RTTY. So again the higher level the license the more privileges you get. Not to mention the ITU has split the world into 3 separate regions, each with it’s own band plan. The good news is most of these overlap with each other, so you can communicate around the world as long as you use a frequency that’s acceptable for that region and yours.
Popular Bands So what are some of the most popular bands? The following will show the more common bands and when to use them. Just make sure your license allows you that band and check the restrictions.

* It should be noted that band conditions vary for many reasons and thus all of these bands can at times take on the characteristics of others. We will discuss this in the section titled Propagation later on.
HF Bands For those that want to try for that long distance or overseas contact the HF bands are for you. They offer propagation sometime during the day, night or season, allowing one in Japan to talk to England, or the US to talk to Australia. No matter what time of day it is there’s usually a band available for the DX. During sun cycles and solar flares different bands can be used for communication , this will be detailed later on in the lessons.
