Peter VK3ZPF has shared this interesting blog… Thanks Peter.
Hi, my name is James Stevens and my passion is Amateur Radio. I’m a newly licensed ham (since 2013) but have progressed through the licensing scheme in less than a year to get my advanced callsign M0JCQ.
Here is my blog entry Top 10 Reasons to Take Ham Radio Portable...

Many Venturers, Rovers and Leaders around the world combine a little bush walking with Amateur Radio. Here is another good reason to take your light weight radio gear, Summits on the Air (SOTA)
Quite a few Scouting Radio Operators are getting involved in SOTA. Two active Scouting Radio Operators are Kevin, VK3KAB and Peter VK3ZPF.
Here is the link to Peter Fraser’s (VK3ZPF) Blog
Thanks to Peter and Kevin, for providing good information, ideas and many useful links including a good guide to getting started.
What is a Amateur Radio Contest ?
Contests are a popular aspect of the amateur radio scene. Contesting gives you an opportunity to practice and develop your operating techniques, and to see how well your station is performing.
Purpose of Amateur Radio Contests?
Radio Contests have one objective, to get many stations on air and to increase the opportunities for making contacts.
Who takes part in contests?
Contesting is popular both around Australia and worldwide. Though out the year, mostly on weekends, there are a number of local, Australian and international contests. The contests are operated under known rules and suit the various interests of most amateurs.
There are contests for the HF bands, for the VHF-UHF bands, and for all bands. Some contests are designed for restricted power and are ideal for Australian foundation operators. In addition to voice mode, some contests have special sections for modes including CW and other popular digital modes. Most contests have different sections for individual amateurs and multi-operator or club stations.
Where can you find out more information? One good source is the WIA contest pages
If you have not had a go at contesting, talk to other members of the team. They can recommend ideal set up, PC logging software (e.g VKCL) and suggest portable operating sites.
Enjoy, have fun and remember it does not really matter who wins 😉 Philip – VK3JNI
Many new operators find that they start operating their new Christmas or Birthday present over the Christmas Holiday. The new antenna gets installed and we start calling CQ… Don’t forget that a brief message on Twitter including #SRESU or #CQ and including your Callsign, Frequency and time of operation will help people to find you.

Did you know that the ocean racing yachts have to carry several pieces of radio equipment including both VHF and HF Radios? Depending on your location, most of our Amateur Radio Equipment is capable of receiving either VHF or HF position reports directly from each yacht taking part.
All boats shall be capable of transmitting/receiving, as a minimum, on the following frequencies:-
VHF – International Marine Channels 16, 72, 73, 80 and 81
HF/SSB – 4483kHz and 6516kHz (Remember all HF transmissions are Upper Side Band)
This is in addition to sat phones and other tracking devices.
All Yachts are required to maintain a 24 hour listening watch for the duration of their race on VHF Channel 16.
The Sailing Instructions will require that boats report by radio when they are in the vicinity of Green Cape and make a declaration confirming their time of passing as well as the following:
- The HF radio is fully operational
- Liferaft(s) are on board
- Engine and batteries are operational
- Boat and crew are in a satisfactory condition to continue
- The skipper has comprehensively considered the most current weather forecast and
- the boat and crew are fully prepared for the conditions forecast.
Regular radio scheduled contacts must be made by all boats. The motor vessel “JBW” will be the Radio Relay Vessel. “JBW” will conduct radio skeds for position reports and listening schedules and monitor the race frequencies. If required, Hobart Race Control will conduct the sked. Hobart Race Control is based at Tascoast Radio at The Royal Yacht Club of Tasmania. “JBW” will maintain a continuous listening watch on the following frequencies throughout the race:
- 0700 – 2000 hours on 6516 kHz
- 2000 – 0700 hours on 4483 KHz
- VHF Channel 16.
Daily position reports will be conducted as follows:-
- 1905 hours on 26 December 2015 on 6516kHz
- 0005 on 27 December 2015 and on each subsequent day on 4483kHz
- 0735 and 1705 hours on each subsequent day on 6516kHz
A weather report may be issued at this time.
The position report routine will be as follows:
(a) “JBW” will commence transmission on 6516/4483kHz (as appropriate) two minutes prior to the sked time with a long tuning call and contact Hobart Race Control. All boats shall tune their radios during this period and not during the schedule.
(b) Each boat when called shall make a position report on 6516/4483kHz (as appropriate) as follows: its Latitude and Longitude in DEGREES and WHOLE MINUTES (not decimals) as at 1900 on 26 December 2015 and at 0000, 0730, and 1700 as appropriate, on subsequent days (not at the time of reporting). If the position is copied, the boat name and its position will be repeated and the next boat called without a break in transmission.

Enjoy your Christmas and holidays.

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.
Looking for J-Code information? see http://jotajoti.info/j-code/
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
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
Hi all, I know you have been hanging out to register your 2015 JOTA /JOTI stations. Registrations are now open an registration forms should now work. Please let me know if you find a bug. – Philip VK3JNI
Hello all stations,
Living with acronyms is an unavoidable fact of life in the 21st Century! Consider the following example:
ACMA has informed OMC which is operated by AMC, an institute of UTAS, that MROCP and MROVCP are now re-named to reflect ITU terminology and align the naming of Australian certificates with the common world practice. (credit to Sam from OMC).
In a nutshell, the Office of Maritime Communications (OMC) will henceforth issue Marine Radio Certificates under the following new names:
1. Short Range Operator Certificate of Proficiency – SROCP (to replace the current MROVCP)
2. Long Range Operator Certificate of Proficiency – LROCP (to replace the current MROCP)
The new terminology will better reflect the nature and limitations of these internationally recognised certificates and their equivalency with overseas certificates.
Since the existing MROCP and MROVCP (certificates) have no expiry dates, their holders have no obligation to replace them. Nominal fee applies if a replacement is required.
