Amateur Radio, what is it?

Post by RF-Bot »


Amateur radio, also known as 'Ham Radio', is a relatively active hobby within Tasmania. There are 35 repeaters around the state, which operate on 50MHz (6m), 144MHz (2m) and 430MHz (70cm). Also used are simplex channels which can range between 144-148MHz, and 420-450MHz.

VK7 regional news is broadcast every Sunday morning at 9am on UHF CB channel 15 followed by national news. Listening to amateurs all depends on the listener's taste - conversations can include technical talk, politics, the weather and even what was for dinner!

Amateur radio hobbyists can use 25 watt transmitters which can offer good reception when the conditions are right.

There is a difference between HF and VHF/UHF Amateur radio. First, amateurs from NZ, UK, USA, Canada and other locations around the world use "DXing" to talk to one another. "DXing" means talking over a long distance, mainly internationally, and requires a good knowledge of your radios and antennas. Another aspect to HF is the ability to decode SSTV (Slow Scan TV), especially taking into account that the picture could be from a hobbyist in Europe or Africa. VHF/UHF Amateur radio tends to be used for shorter range, up to 100km in general. This can be through a repeater as above, or simplex.

If you have ever heard call-signs like VK3 or VK7 and aren't sure what they mean, then see below.
