TIARA

Tokyo International Amateur Radio Association

7J1YAA / 7J1YAB

Meetings

The next TIARA meeting will be Friday, July 18th (N.B. the third Friday) at the Nakameguro Juku Center.

Agenda

TIARA President Arie Lukkassen, JE1RYS, will make a presentation on electronic circuit simulation with an emphasis on simple RF circuits, Monte Carlo design test verification, bode diagrams and plenty of easy to follow examples. He will show simple circuits which everyone can follow and the focus will be on showing the capabilities of the tool.

His aim is to get you interested in trying out one of those exciting simulator programs and learn and improve your electronic circuit knowledge. It is kind of homebrew without buying or soldering the parts together. Also most software includes virtual Test & Measurement Equipment and the results are very realistic.

These software simulators are not useless toys but are used by all major companies to improve R&D efficiencies (to do more with less), improve time to market and reduce the number of prototype iterations and recently also used at Universities to teach electronics.

If you have time please have a look at this YouTube link. It shows an overview of the TINA tool which we will use during the presentation.

The Tokyo International Amateur Radio Association (TIARA) holds monthly meetings in English usually in Jiyugaoka, Tokyo. Jiyugaoka is just a few minutes from Shibuya on the Tokyu Toyoko Line, or from Oimachi on the Tokyu Oimachi Line. Meetings are held on the third Friday of most months except August (Field Day & Ham Fair) and December (Christmas Party). The meetings are open not only to members, but other English-speaking hams and foreigners residing in or visiting Japan interested in amateur radio.

US Amateur Exams in Tokyo

The ARRL VEC Tokyo VE Team (which is not directly affiliated with TIARA, but which contains some members) conducts examinations for US amateur radio licenses at least twice a year in the Tokyo area.

The next session will be held July 26th at the Takinogawa Higashi-Kumin Center. Information and pre-registration are available from ARRL VEC Tokyo. Start studying now! A US amateur license can be your gateway to getting a Japanese reciprocal license while you are here.

You can also check the ARRL US amateur exam registry for Japan to find other sessions.
