  The first wireless hack
Posted by: News Man - 11-22-2017, 03:45 AM - Forum: Amateur News - No Replies

In this video Tom Scott describes the first ever wireless hack carried out by Nevil Maskelyne in 1903

No, it wasn't called "hacking" back then: it was called "scientific hooliganism". Let's talk about Marconi, Nevil Maskelyne, and a demonstration that didn't go as planned.

The Deccan Herald reports:

Amateur operators with high frequency radios will provide communications support to EC officials in areas with negligible or zero mobile telephone network. In a letter to Ambarish Nag Biswas VU2JFA, secretary of West Bengal Radio Club (Amateur), the poll panel has asked for support during the six-phase polls in Bengal, starting from April 4.

  DX Engineering Supports the EP2A Iran DXpedition
Posted by: News Man - 11-21-2017, 12:07 AM - Forum: Amateur News - No Replies

DX Engineering provided the EP2A Iran DXpedition team with a Hi-Z Antennas Triangular Array System as they attempt to activate the country under callsign EP2A and make contact with as many other Hams from around the world as possible. Iran is seldom activated, so this is an excellent opportunity for operators pursuing the prestigious DXCC award to grab a rare contact.

  ARRL Tells FCC to Restore Balance of Modes on 80 and 75 Meters
Posted by: News Man - 11-19-2017, 07:20 PM - Forum: Amateur News - No Replies

In comments filed on March 23 on its Petition for Rule Making (RM 11759) seeking changes to 80 and 75 meters, the ARRL has told the FCC that its primary objective is to “rebalance” the bands by correcting a 10-year old FCC error.

“ARRL’s proposal is not fairly viewed as a proposal to take anything away from anyone,” the League’s comments assured. “It is more properly viewed as the effectuation of a fair, equitable, and efficient ‘band plan’ looking forward for the foreseeable future that balances everyone’s needs, and which remedies a plainly unfair plan, imprudently created in the 2006 Report and Order in WT Docket 04-140.”

  555 Plasma Speaker
Posted by: News Man - 11-16-2017, 08:57 PM - Forum: Amateur News - No Replies

The 555 can do anything. OK, that’s become a bit of a trope in our community, but there is quite a lot of truth behind it: this little timer chip is an astonishingly versatile component.

[Alexander Lang] has added another achievement to the 555’s repertoire, he’s used one in the creation of a plasma speaker. Working at Hackspace Manchester, he’s used the 555 as a pulse-width modulator that drives a flyback transformer through a MOSFET, which feeds a spark gap mounted in a lasercut enclosure. The results maybe aren’t yet hi-fi, but it works, and is very audible.

  Comedian, Actor, TV Writer and Personality Garry Shandling, ex-KD6OY, SK
Posted by: News Man - 11-16-2017, 12:22 PM - Forum: Amateur News - No Replies

Comedian, actor, and TV personality Garry Shandling, ex-KD6OY, died March 24 after suffering an apparent heart attack in Los Angeles. He was 66. Shandling became a ham as a teenager in the 1960s, long before he entered show business.

“When I was 13 I had a ham radio set (true!), so I could sit in my room and talk to people the world-over. Geeky? Or just ahead of my time!!?” Shandling had tweeted in May 2011.

  The signal and the noise (Florida)
Posted by: News Man - 11-15-2017, 10:14 PM - Forum: Amateur News - No Replies

Bill Preen scanned for other HAM radio operators on his digital setup.

“I think I got one from Switzerland,” he said.

Preen is a member of the Suwannee Amateur Radio Club, a group of about 30 HAM radio operators based out of a club house off of North U.S. Highway 129.

SARC has existed for about eight years, Preen said. The club was founded by John Beaver, of local trucking company Beaver Bulk, Inc.
