Ever watch the Stranger Things series on Netflix? It also features some excellent electronics technology that was at its prime back in the 80s and is still kicking today. In one scene, three boys are sitting around their very first ham radio with their science teacher in tow.
Amateur radioalso known as ham radiois the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosportcontestingand emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;"  either direct monetary or other similar reward and to differentiate it from commercial broadcastingpublic safety such as police and fireor professional two-way radio services such as maritime, aviation, taxis, etc. The amateur radio service amateur service and amateur-satellite service is established by the International Telecommunication Union ITU through the Radio Regulations.

Their support includes long distance communication DXingthe introduction and promotion of amateur radio in developing nations and encouraging youth participation in amateur radio.
During the period when spread spectrum was just coming into use for ham radio, SSS Online's founder, Randy Roberts, was very involved in creating design ideas. The original diagrams and the first piece of text were posted on the site on April 13, The second piece was posted November 6, No changes have been made to the content of this page since that time; all revisions are to format and advertising.
Designed for the commercial, government, amateur radio and short-wave listener communities, this software provides a powerful interface for all SDR users. There are total of five projects that are needed for the new revision. The station broadcasts on a network of 15 FM frequencies and 2 shortwave transmitters across Southern China from studios in Nanning, Guangxi province.

Even though I owned a ham rig — a comparatively cheap amateur shortwave radio transceiver sold, back in the day, by Lafayette Electronics — I never earned the requisite ham license. Among other things, I repeatedly failed to master Morse Codeand was so embarrassed that I decided to fake it. Short for Quebec Sign Language, these cards employed the Q radio broadcasting language to confirm receiving a transmission.
Not all of the pins or wires are used. It always seems that there is always a cable coming loose, causing the whole mess not to work. The finish, attachment, and other details of the badge must also be selected. See more ideas about Electronics projects, Diy electronics and Electrical Engineering.
The NARC group invited us to their March meeting where we shared our presentation with the nice group of folks in the Club. I wanted to post an overview of what we shared as well as a link to the full presentation so that our readers can have a look at the material and hopefully benefit from the information that we have assembled. I have also used this post as an opportunity to create an index to all of the articles on this Blog related to the design, construction and performance of our station.
Homebrew is an amateur radio slang term for home-built, noncommercial radio equipment. Some items can be home-brewed at similar or lower cost than purchased equivalents. In the early years of amateur radio, long before factory-built gear was easily available, hams built their own transmitting and receiving equipment, known as homebrewing. Homebrewing was often encouraged by amateur radio publications.
