Raspberry Pi for HAM Radio – Projets radio. Introduction Since 2012, the Raspberry Pi nano computer has become an increasingly important part of the DIY and « maker » community.
The increase in power of the Raspberry Pi over the years offers very interesting possibilities for radio amateurs. Indeed, it allows not to permanently monopolize a PC in the decoding of frames with software like WSJT-X, FLDIGI, etc…, without forgetting the possibility to control the Raspberry Pi remotely and thus to be able to work outside the radio shack as I can sometimes do on my couch. Moreover, this nano computer is now widely used in any Hotspot (DMR or D-STAR). Ham Radio Videos. Hamuniverse Ham Radio Videos and Ham Radio Video Links!

US National Lighthouse-Lightship Weekend (NLLW) – Amateur Radio Lighthouse Society.
Celebrating National Lighthouse Day Coinciding with the US National Lighthouse Day, the US National Lighthouse-Lightship Weekend (NLLW) is an annual lighthouse operating and activation opportunity celebrating the anniversary of the establishment of the United States federal lighthouse service.
This is a day to celebrate lighthouses, lightships and the commitment and service of those who tended America’s lights for generations. Dates National Lighthouse Day is unofficially August 7th each year. Files – Contest University© – Dayton Ohio. QRP ARCI - QRP Kits, Bits and Supplies. QRP ARCI - Awards. The QRP Amateur Radio Club International 'Elmer Award' may be submitted by any QRPARCI member for someone who has helped them along their amateur radio journey.
Traditionally Elmers were probably defined as someone, usually an older ham, who provided a helping hand and guidance for someone, usually younger, entering the ham radio community. In today's fast paced, ever changing world of technology, communication advances, and the advancing age of many hams the Elmer can be viewed from a different perspective. Grounding and Bonding for the Amateur. Size of Grounding Conductors On page 3.11, the statement "The ground conductor must be at least as large as the current-carrying conductors...
" is a good guideline but the actual wording of NEC Article 250.122 is that "the ground conductor can not be required to be larger than the current-carrying conductors. " (Other ground conductor sizing rules are also given for situations unlikely to apply to amateur stations.) This is a good example where the book must simplify the NEC rule in order to be understandable and useful to the individual ham. If your station wiring is in any way unusual, unorthodox, or combined with other non-ham equipment, you should consult with a licensed electrician.

Connections explores an Alternative View of Change (the subtitle of the series) that rejects the conventional linear and teleological view of historical progress. Burke contends that one cannot consider the development of any particular piece of the modern world in isolation. Rather, the entire gestalt of the modern world is the result of a web of interconnected events, each one consisting of a person or group acting for reasons of their own (e.g., profit, curiosity, religious) motivations with no concept of the final, modern result of what either their or their contemporaries' actions finally led to.
The interplay of the results of these isolated events is what drives history and innovation, and is also the main focus of the series and its sequels. Connections (1978) 1. Home Page.
