Introduction to Amateur Radio |
Amateur Radio or HAM radio is a
world wide hobby. It's a hobby that is more so designed for those that are
really into radio communications, those that are really interested in it. To
operate on HAM radio bands you need a license, and there are different classes
of licenses. In Australia for example, you can't operate on any of the bands
below 28MHz (10m band) until you have passed exams in sending/receiving Morse
code at 5 words per minute.
HAM Radio has several bands throughout the Radio Spectrum. They have several HF
slots, 2 VHF, 1 UHF, and more SHF allocations. For instance, the 144MHz to
148MHz band is called the '2m' band. This is because the approximate wavelength
at those frequencies is 2m.
Band | Frequencies |
160m | 1.8 1.875MHz |
80m | 3.5 to 3.7 & 3.794 to 3.8MHz |
40m | 7 to 7.3MHz |
30m | 10.1 to 10.150MHz |
20m | 14 to 14.350MHz |
17m | 18.068 to 18.168MHz |
15m | 21 to 21.450MHz |
12m | 24.890 to 24.990MHz |
10m | 28 to 29.7MHz |
6m | 50 to 54MHz |
2m | 144 to 148MHz |
70cm | 420 to 450MHz |
23cm | 1240 to 1300MHz |
On HAM radio you are allowed to operate using a variety of modes. These include
Packet Radio, SSTV, RTTY, FAX and others. Through the use of amateur radio you
can make world wide contacts at several different points within the radio
spectrum. There are clubs you can join, swap meets to go to, and other events
all related to the use of amateur radio.
