Personal Privacy Jammers
by Joseph C. Grabowski

When jamming interfered with GPS signals at Newark Airport, a three-month effort determined that low-power, mobile personal-privacy devices were responsible. This article describes how they were found and outlines how the observable parameters of such devices encompass a wide variation in RF spectra and internal modulation.

On the 18th of April, 2012, Radio Amateurs will celebrate the World Amateur Radio Day on the 87th Anniversary of the founding of the International Amateur Radio Union (IARU).

This year's theme for the World Amateur Radio Day is: "Amateur Radio Satellites: Celebrating 50 years in space" in remembrance of the launching of OSCAR 1 on the 12th of December 1961, and OSCAR 2 on the 2nd of June 1962.

Note: OSCAR stands for Orbiting Satellite Carrying Amateur Radio.

Branch 74, The Wellington VHF Group Inc. has been granted use of the special callsign ZL2WARD for World Amateur Radio Day.

ZL2WARD will be active on the National System, and other frequencies, for which a commemorative QSL card will be issued.

Meet at the Tawa Community Centre, Cambridge Street, Tawa, starting at 7:00pm - PLEASE NOTE EARLER TIME

Foxes will be transmitting from start time onwards. The frequencies will be advised on the night and also will be posted on the venue door.

Please cease hunting at 8:30pm, and meet at McDonalds Restaurant, Porirua for a debrief and supper of your choice.

Come along and have some fun!

This is an interview with The Yaesu NA boss, which hints about new modes, radios and repeaters. No specifics, but a "watch this space" type talk.
