Try Something Exotic!

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.

SDR – Try it out

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.

Enjoy!

Cool HF Radio Apps from the Black Cat

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.

Amateur Radio

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

New emergency Marine radio service

With warmer weather many scouts and their families are heading out on the water in boats.

Marine safety in Victorian coastal waters has received a major boost with the launch of Marine Radio Victoria, the new marine distress and emergency monitoring service.

Marine Radio Victoria (MRV) monitors and records radio traffic on VHF and HF emergency radio channels 24 hours a day, 365 days of the year.

Post JOTA / JOTI Reporting

Reporting

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.
