Amateur Radio is seen by many as the hobby of gray haired old men listening to scratchy noises. There is so much more to the hobby.
WSPR is one of the more exotic combinations of PC and HF radio. Low power signals containing a radio callsign and location are transmitted at random on known frequencies around the world. Other stations with PC connected to their radio receivers monitor these frequencies and the results are plotted on the screen. Results are also automatically uploaded to the Internet for others to view and study.
This is real STEM activity. How far have the signals traveled? Why do they change? How can we hear more stations? Lots of activities and thoughts can spin off!
You can be part of this experiment with a moderate cost Short Wave Receiver, a PC, some free software and a simple home made interface. You can leave it running in silence over night or when doing other things. You will be amazed at the signals that you can decode.
Could this be an interesting JOTA related activity? Yes, signals can be received with out having to hold a radio licence. All can be done with out any gray hairs or scratchy noises in the house to annoy others too.
Contact the Radio and Electronics team for more. information.
Enjoy – Philip VK3JNI.
Have you ever wanted to listen to Short Wave Radio but you don’t have the equipment? Tecsun, an Australian company in NSW have made available a Software Defined Radio (SDR) on the internet. The receiver is located in Gosford NSW. Yes you can enjoy all the real fades and other noises we associate with HF Radio.
You can tune it to the desired HF Frequency and Mode (e.g. select frequency 4835 MHz, select the mode AM and you may hear the new Australian Short Wave station Ozy Radio, currently reporting an power output is 500w and the location is confirmed as Razorback near Camden approx 45 km southwest of Sydney.)
You can also listen to the amateur, marine and explore other interesting data on the HF bands too using the SDR.

HF and Shortwave bands can be full of strange voices and noises. Some good fun can be had by experimenting with radio and PC , Mac or Android devices to try to decode the data within some of the noises we hear.
One company who has released some interesting apps is Black Cat Systems.
Visit http://blackcatsystems.com/ to view their catalogue.
While our license conditions may restrict our foundation operators from transmitting digital signals, everyone can receive and try to decode the data signals we hear on air.
Have fun… Philip – VK3JNI
Just a reminder that we need to collect information over the weekend to compile your reports. Can you remind your JOTA JOTI stations to capture numbers over the weekend? The following would be great:
Number of Scouts
- Scout sections involved
- Number of Visitors (non-Scouts)
- Number of JOTA JOTI Stations
- Number of Amateur Radio Operators
- Number of Contacts/QSOs
- States Contacted
- Countries Contacted
Also it would be interesting to get a better picture of JOTI, eg how many stations ran JOTI, were there any stand alone JOTI stations. What apps were used over the weekend etc.
Any stories or photo’s/video would be great as well.
I will confirm the deadline for reports early next week however it would be great to get these done ASAP while the event is still fresh.
Have a great JOTA JOTI.

The 2016 JOTA-JOTI reports has been published – over 1 million participants across 156 countries and 33,000+ locations.
Read all the details including individual country reports by downloading the World JOTA-JOTI 2016 Report FINAL
This is a big report so it may take some time to download. One quote from the report…
“This was our first JOTA-JOTI experience and I think the Scouts had more fun than expected. We really enjoyed chatting with all of the different groups around the world. Uniforms, badges, and awards were a common topic. One thing we learned is that it is very common for people in other countries to speak multiple languages. All of our conversations were in English, and for most contacts English was not their first language. Another fun thing our Scouts learned is that other Scouting organizations have co-ed groups. Our longest chat was with a remote group in Australia who were 4.5 hours away from the nearest McDonald’s. They were sad to see us go as we had run out of time at the end of our event.” – Boy Scouts of America

Can you believe it? Cub Scouts are turning 100 in 2016. As part of the celebrations, many Cub Scouts will be taking part in JOTA / JOTI this year.
CUB 100 call sign extension. If you are operating Amateur Radio with Cub Scouts present, you are invited to add the suffix CUBS 100 after your callsign. This will signal that your station has Cub Scouts present and keen to say hello.
Murray VK3MJT will be encouraging a number of radio clubs to operate as a drop in centre for Cub Scouts over the JOTA / JOTI weekend.
In Murray’s words, if I had a Cub pack with me, the extended call sign I would be using would be VK3MJT-CUBS100. By using and by listening for the extended call sign you know that Cubs are there on the air.
Please don’t forget to register your Cub Pack’s involvement in JOTA / JOTI you can order your JOTA/JOTI 2016 badges here too.
A special CUB callsign has been applied for and this will be on air from nominated location through the year including JOTA weekend. More information to come.

has produced a new PR video for JOTA/JOTI 2016. Well done!
The gauntlet is down let’s see what we can do for scouts.
