Welcome to any visiting Guides, parents, guardians and friends
This evening we will do our best to put on a little demonstration of Amateur Radio, and rather than print out a sheet of information containing images and links etc. I thought I'd save the paper and drop an article on our website, so hopefully you'll find us.
Here is a simplified image, showing a range of frequencies, how frequency relates to the types of Electromagnetic Radiation, and some of the uses we have for them. As you can see, most communication technologies use frequencies at the lower end of the range. Click the image below for more information.
Below you can see a world map, showing where signals from our club callsign G3ZMS landed during a brief test session on the day of the demonstration.
You can view reports from any callsign at any time by visiting the PSKreporter website here: https://www.pskreporter.info/pskmap.html and entering the callsign.
Reports do only stay on that site for 24 hours though, so don't hang around!
KiwiSDR - online radio, but not as you know it!
Visit our Homepage, scroll to the bottom and click the WebSDR banner. The bookmarks at the top of the WebSDR display hint at what you can expect to find at individual frequencies. Right at the very top, you can see the various bands - including the amateur bands in blue.
Try zooming in and out, clicking on a particular signal on the waterfall and then try out the various modes to see what you can hear, like USB, LSB, AM, FM and CW. You can also adjust the little coloured 'hat' near the top, to make it fit the width of the signal and to get the best results.
A lot of signals will be data and not speech. To investigate those, you'll have to do a little research, or ask us to come back and do another talk!
In the meantime, thanks for visiting our website, and we hope you enjoyed the demonstration.
