62nd Jamboree on the Air

0

JOTA-JOTI is the largest Scouting event in the world with over 1.3 million Scouts participating across 150+ countries. Scouts and Guides across the world connect with each other during JOTA-JOTI using the airwaves and the internet.

JOTA is a spectacular opportunity to introduce Scouts to amateur radio. For many, this will be their first exposure to the world of ham radio. Some will go on to become hams, enjoying the hobby for a lifetime. A few will even find the basis of a career in science and technology.

The event has been held the third weekend of October since 1957.

The next Jota will be 18-20 October 2019

Why is there a JOTA-JOTI ?

JOTA-JOTI Purpose

Jamboree on the Air – Jamboree on the Internet (JOTA-JOTI) is a fun and exciting annual experience for all young people in Scouting using the widest range of technology communication channels to educate, promote cultural awareness, develop tolerance, as well as enhance sharing, collaboration and teamwork, along with building a sense of belonging to the worldwide Scout Movement. It is a “travel-free” Jamboree that takes place wherever you are in the world.

JOTA-JOTI Description

Jamboree on the Air – Jamboree on the Internet promotes a Scout’s sense of belonging to the worldwide Scout Movement and builds cultural awareness, develops tolerance, advocates sharing and collaboration as well as demonstrates teamwork.

It provides exciting opportunities for young people to explore technology and to develop technical skills including fostering innovation and creativity through communicating with other Scouts. A wide range of activities using communication technology are the chief methods of attaining these goals.

JOTA-JOTI strives for a meaningful engagement of as many young people from as many parts of the world as possible annually on the third weekend in October. This weekend is also an occasion to celebrate Scouting and to generate positive energy to support the development of the Scout Movement.

The event seeks to promote quality Scouting in a manner faithful to the purpose, principles and method of Scouting and consistent with the needs and aspirations of young people in today’s world.

The JOTA-JOTI programme shall be a reflection of the Promise, Law, Principles and Method of Scouting, as defined by the WOSM Constitution, and shall also reflect the most up-to-date policies and initiatives of WOSM relating to youth programme for all ages.

JOTA Operating Rules

  • All radio operators must operate their station strictly in accordance with FCC regulations.
  • Stations should try to contact each other by calling “CQ Jamboree” or “CQ JOTA” or by answering other stations sending this call.
  • Any authorized amateur radio frequency may be used. It is suggested that the frequencies listed below be used, at least for a starting point. Once contact is established, you can move to another frequency to leave the calling frequency open for others.
  • Any amateur mode of operation can be used such, as CW, SSB, PSK, SSTV, FM, and satellite. The more modes in operation, the more exciting the event will be for the Scouts.
  • JOTA is not a contest. The idea is to contact other Scout stations and allow as many Scouts as possible to talk to other Scouts and learn about who they are and what they are doing. You might think about counting the Scouts on both sides of the QSO rather than the number of QSOs!

JOTA Suggested Frequencies

  • All frequencies are shown as megahertz.
  • Primary HF recommendations are for General Class licensees. Technicians may take advantage of 10 m and VHF/UHF for voice communications.
  • After contact is made on Calling Channel or frequency, move to another channel or frequency for QSO.
  • Experiment with modes prior to JOTA or Radio Scouting demo. ‘Murphy’s Law’ prevails!
  • Use web search tools to find lots of helpful information about any of the modes commonly used for JOTA and Radio Scouting.
  • WOSM (World Organization of the Scouting Movement) calling frequencies are shown to indicate center of international activity.

D-STAR

REF033A has been allocated as a full-time JOTA/Radio Scouting D-STAR Reflector. After contact is established, stations should disconnect from REF033A and connect to one or other repeater or migrate to an unused Reflector.

SIMPLEX Channels: 145.670*, 145.640, 145.610, 438.010. * 145.670 and 438.010 are commonly used as the National D-STAR Simplex Channels and should be used only as Calling Channels for JOTA. Always listen first to avoid interfering with another QSO.

DMR

All wide area talkgroups are permitted for use for JOTA for establishing contacts. After contact is established, stations should utilize as few resources as possible. For international, national, and regional QSO’s, stations should move their transmissions to one of the DMR-MARC UA talkgroups or to the DCI TAC-310 talkgroup.

For intrastate contacts, stations may use their area’s statewide talkgroup (if applicable). The use of your repeater’s local talkgroup (if applicable) is always permitted.

SIMPLEX Channels: 441.0000*, 446.5000, 446.0750, 433.4500, 145.7900*, 145.5100. All simplex frequencies operate on time-slot 1 and use color code 1. (*are commonly used as the National DMR Simplex Channels and should be used only as Calling Channels for JOTA. Always listen first to avoid interfering with another QSO.)

FT8 Frequencies

FT8 “Franke-Taylor design, 8-FSK modulation” is an Amateur Radio Digital Mode that belongs to the family of weak-signals communication protocols, developed and promoted by K1JT Joe Taylor.

The FT8 protocol is implemented in several application programs including the popular weak signals software WSJT-X , JTDX and the Chat FT8-based software JS8Call that implement a different modulation and can be found in different ft8 frequencies

FT8 should be used in the following amateur radio frequencies:

Major Enhancements to the SOTABEAMS WOLFWAVE Advanced Audio Processor

The WOLFWAVE Advanced Audio Processor offers a huge range of facilities to improve radio reception in difficult and noisy situations. The latest firmware release for this innovative product adds new functionality for SSB and CW users as well as those with hearing difficulties.

Binaural Mode

The new binaural mode goes well beyond the simple “binaural” implementations in many transceivers (which is generally just a delay or phase shift) to deliver a truly immersive “sound field” for the CW operator. Using an artificial head model, different tones appear to come from different directions, giving a whole new way for signals to be differentiated. Three separate modes are available to experiment with, each being fully adjustable.

SSB users had requested notch filtering for interference such as ADSL carriers. SOTABEAM has implemented 10 notches with bandwidths as low at 100 Hz and very sharp edges.

Wolfwaves Spectrum Display

The notches are shown on the WOLFWAVES spectrum display making them easy to adjust for optimum performance.

Users with age-related hearing loss are already catered for with a sophisticated system that just requires them to enter their age and sex to benefit from a median hearing loss correction.

New with this firmware release is a left/right balance facility to help people with asymmetric hearing loss.

The new firmware is available for all users to download at: www.wolfwave.co.uk/firmware

How To Get An Amateur Radio License

Amateur radio (or Ham Radio) is an exciting hobby. Almost everyone knows a family friend or relative who is an Amateur Radio operator. If you speak with them about the hobby they may start using strange words such as Antennas, bands, propagation, standing-wave ratio. Don’t be frightened! You don’t have to have a Ph.D in physics to enjoy the fascinating world of Ham Radio, but you need at least to get your license.

Age or disability is not a barrier to obtaining a license. Many disabled have found Amateur Radio to be a great way to “travel” to exotic places all over the World without leaving their home. Children, even as young as five years old, have successfully become Ham Radio operators!

By international treaty, the amateur service for ham radio in every country is a licensed service. Examinations and licensing types and policies in each country are regulated by the local regulatory authority. (FCC in the US, Ofcom in the UK, Industry Canada, ACMA in Australia etc.)

In this article we will not cover all aspects involved in getting a license in every country, since each national Agency or Ministry administer licensing procedures and polices in different way,  if you are interested in further details we recommend you to  contact your local Amateur Radio Society to obtain  complete information.

Amateur licensing

Amateur radio licenses schemas vary from country to country. In some cases there are several grade of certification, which you can upgrade by passing additional examinations, in other countries there is just one license type and also one exam type only.

Licenses are subject to expiration, in some cases yearly in some other every five or ten years, and need to be re validated, usually without requiring any additional examination.

Licenses are often subject to periodical issue/renew, and are subject to fees.

Exam Preparation

Several local Amateur Radio Associations publish study guides and even organize classes, where you can study and practice for the examinations along to other candidates.
Since examination are different from country to country, you should study using books and publications related to your country examination plans.

There are even several online websites offering exam practice tests, and lots of web sites offering past exam question pools, but as said before you should need to refer to your country Exam program, and the best way is to keep in touch with Ham Radio Clubs near you.

In several countries exams usually consists of several multiple-choice questions about  Electronics, Communication Procedure, international rules

Morse Code requirements

In most of the countries worldwide, morse code is no more a requirement to get an amateur radio ticket. But this is not true everywhere.

Morse code proficiency is in some countries still a requirement for some classes of license. At this time, some countries like India, Pakistan, Mexico or in example IARP countries, still requires CW proficiency especially for HF operations. Like for exam preparations, Amateur Radio Clubs organize classes where is possible to learn morse code.

Ham Radio Licensing in the US

There are three classes of Amateur Radio licenses: Technician, General, and Amateur Extra. The entry-level license, Technician, is relatively easy to obtain. This license allows the holder to use a wide range of radio frequencies — everything above 50 MHz. This includes the popular “2-meter” band, satellites, microwave, packet radio, and much more. It is no longer necessary to pass a Morse code test to obtain a license! Removing this barrier, although controversial at the time it was enacted, has allowed the hobby to grow substantially in recent years. Advanced license classes, however, still require demonstration of Morse code proficiency.

The Amateur Radio licensing process is very straightforward. Applicants must pass a multiple-choice written test demonstrating an understanding of FCC rules and competency in basic radio theory. The question pool is widely available on the Internet and is part of most commercial study guides. The test is administered by other Amateur Radio volunteers (called Volunteer Examiners or “VE’s”). Many clubs hold these tests in convenient locations on a monthly basis.

Several commercial study guides are available to help you pass the 35-question written test. One of the best is “Now You’re Talking!” published by the Amateur Radio Relay League (ARRL). The ARRL is the national association for Amateur Radio and most “Hams” are members. The ARRL also publishes a popular pocket guide called the “ARRL Repeater Directory” which lists by geographic area all public Amateur Radio repeaters (machines that retransmit low power signals over a wide area). “Now You’re Talking!” contains the entire test question pool (with answers) and can help you quickly identify your areas of weakness. It usually takes just a few hours of study to prepare for the Technician license exam.

After you pass the written test, the Volunteer Examiners will assist you in mailing your license application to the Federal Communications Commission (FCC) for processing. Few weeks later you will receive your license in the mail with your new call sign. Most Hams find that passing the test and receiving their license is just the beginning — most learning happens after you become licensed!
