J-Code – Common Language for JOTA / JOTI

J-Code

J-Codes ( or J Code ) are designed to enable very basic communication between Scouts that do not share a common language.  By ‘talking’ in J-Codes individuals are able to ask and answer questions without either person being any to speak any of the language of the other.

Follow this link below and you will find some sheets to download, print and share in time to help your members ‘talk’ in multiple languages during JOTA-JOTI.

Software Defined Radio using a cheap USB stick

Marine vessel locatons see:

Wondering how they track these vessels, it is done via AIS receivers located around the coast.  Vessels carry a AIS transmitter connected to a GPS and regularly transmit their locaton.

If you would like to try to build a little AIS receiver and you are located around the coast, read on.

SDR AIS Decoding using a cheap USB DVB-T Stick

Hi all, here is a little project for the tech savvy Venturer, Rover or Leader.  This project will be of particular interest if you live near the coast. You can use a DVB-T STICK to build a low cost AIS Receiver. Full credit and thanks goes to the team from MarineTraffic.com …  For more detail see: http://tinyurl.com/oo4r594

If you have not played with the AIS display provided by MarineTraffic.com this may be something new for your JOTA / JOTI station.

During the warmer months I run a smart phone app that puts me on the MarineTraffic.com map when on my little boat..  You may even spot our real yacht SwingShift around the bays or lakes. Enjoy! – Philip VK3JNI

 

 

 

Looking for a portable HF Receiver plus more?

You would love a portable HF receiver! You are on a budget and your wish list includes PLL, AM, FM, SSB, MW, SW and a clock but you thought you where only dreaming?

JOTA is coming up in October and I frequently get asked to recommend a portable radio receiver that could let scouts of all ages tune around and listen in to JOTA stations without the complications of having an unsupervised transmitter sitting in the campsite or station. Check this out… AM, FM and Single Sideband with good coverage range, this portable receiver may meet the needs of new amateur operators, leaders and scouts alike. Includes rechargeable battery… all for under $350, sounds like a good deal. Note, I have no commercial interest in this company, other than buying one myself… It works great!  http://tecsunradios.com.au/sto…/product/tecsun-pl880-radio/…

Need Air Band as well… consider http://tecsunradios.com.au/…/tecsun-pl660-radio-vhf-air-ba…/ This one is smaller and under $200.

Please note, we have no commercial affiliation with this company. – Philip VK3JNI

 

ScoutLink Chat

Interested in trying ScoutLink Chat but unsure of how to do it?

Instructions for getting online with ScoutLink Chat can be found at scoutlink.net

One of the many safety features of IRC chat is protection against clone attacks, this is done by limiting the number of connections from a single IP address.  The default is 20.

If you think your network will have  more that 20 clients connecting to IRC chat, let us know, giving the public IP address of your network, and your limit can be quickly raised.

You can do this by hopping onto the Scoutink chat and seeking out Coppertop, Strike or Jabiru

Enjoy.

JOTA / JOTI 2013

With the JOTA / JOTI weekend of the 19-20 OCTOBER 2013 just around the corner, here is a quick list of resources that may help you with running of your JOTA / JOTI Base.

IRLP – www.irlp.net

IRLP (Internet Repeater Linking Project) allows the linking of repeaters worldwide over the internet. It’s a great way to get some quick contacts when the bands are dead on HF or you’ve exhausted your local contacts.

IRLP is much like using a telephone, on the repeater that is IRLP enabled, after checking that you are accessing one of the IRLP Nodes or Repeaters, we use the DTMF keypad on your VHF / UHF amateur radio to transmit while dialling the 4 digit IRLP Node number. A list of IRLP Nodes can be found here.

Remember, with IRLP, you will need to leave 2 seconds between pushing the button and speaking and use the word over so that the part at the other end know you’re throwing it back to them.  Leave at least 3 seconds between overs to allow the system to reset.

To disconnect from an IRLP node key “73” on your DTMF keypad.  Please remember to close down the nodes during JOTA as others may be wishing to use them.

Echolink – www.echolink.org

Whilst it’s probably a little late to be registering for Echolink on JOTA Weekend, again, it’s another great solution when the bands are quiet. Echolink is a “Computer Radio” program that allows you to speak to other amateurs using a computer and microphone.

You can connect a one-to-one QSO or, using an Echolink Reflector such as SCOUTSAU you can speak to many people just like a UHF/VHF repeater.

Echolink is also connected to Repeaters worldwide, again, remember to leave 2 seconds between keying up and speaking for the best results.

Please remember to set up your Echolink computer and internet connection and test it before JOTA to avoid disappointment.

HF – Call Frequencies List

During JOTA there is are Australian and Worldwide call frequencies so that it makes it easier for you to establish a QSO. Remember to use your manners and QSY off the call frequency once you’ve established your QSO.

VHF / UHF

There’s plenty of repeaters throughout the State and all over the country. Repeaters are a great way to establish local contacts between JOTA Locations. Remember, don’t hog the device, make a few QSO’s then leave the frequency for someone else to part take.

Radio Safety

Whilst it’s great fun to part take in JOTA, it’s a timely reminder to be safe. It’s no fun falling off the roof setting up your station, coming off a ladder, getting hit in the head trying to put up your long wire or zapped with your power supply or radio.  Close your station down and move scouts and guides away from radio or other communications gear if electrical storms are near by.

Safety is absolutely paramount. Ensure your equipment is up to scratch, keep your shack neat and tidy and think safe.

A safe JOTA is a fun JOTA!

JOTI – www.scoutlink.net

JOTI is a great way for people to connect during JOTA. Using IRC Chat kids and adults can converse sharing stories and their JOTA / JOTI experience.

Whilst it’s great fun to do JOTI, it’s also important to remember to WATCH – Child Safety is very important and Stranger Danger is an important topic to raise with the kids. If they don’t feel safe, it’s time to tell a leader. If they don’t like the questions they’re being asked, it’s time to tell a leader. Whilst every effort is taken to keep the IRC channels “kid friendly” it’s not always possible.

Facebook / Twitter

Facebook & Twitter (Social Media) are great ways to connect during JOTA / JOTI. If you’re twitter, make sure you use the hash tag #jota, #joti, #hamradio and #amateurradio. It will make it easier for other Twitter users to follow the conversation.

The final final

With all that said, have yourself a wonderful JOTA / JOTI. I look forward to seeing plenty of photos and reports!
