The amateur radio\narea is what I will be discussing today.</p>\n<p>Many terms within amateur radio find their origins from the days of\ntelegraph, when operators would use Morse code to send messages across\ngreat distances using wires strung from pole to pole. The telegraph\n&#x201C;key&#x201D; (or code key) was basically a momentary contact switch which would\nclose an electrical connection when pressed. Pressing the key down for a\nshort period of time would send a short pulse down the line, which is\nreferred to as a &#x201C;dit&#x201D; (Sometimes the term &#x201C;dot&#x201D; is used). This may be\nwritten using the period &#x201C;.&#x201D; symbol. Holding the key down for a bit\nlonger would send a longer pulse down the line, called a &#x201C;dash&#x201D;\n(Sometimes the term &#x201C;dah&#x201D; is used) and it may be written using the\nhyphen &#x201C;-&#x201D; symbol.</p>\n<p>Telegraph operators became a close knit community, even though they\nwere geographically separated. Often one operator could identify another\noperator by subtleties in the style or personality of how they sent\ntheir messages. This was known as the operator&#x2019;s &#x201C;fist&#x201D; and today we\nwould describe it as a &#x201C;behavioral biometric&#x201D;. As the community of\ntelegraph operators moved around or were replaced, new &#x201C;fists&#x201D; would be\nidentified, as new personalities of code sending were tapped out on the\ntelegraph keys.</p>\n<p>When an operator passed away, it was a loss to the community, and a\nloss of someone who might have been befriended remotely by other\noperators. The term of respect created for this situation was &#x201C;Silent\nKey&#x201D; sent as the abbreviation &#x201C;SK&#x201D; ( &#x2026; -.- ). It meant that the\nparticular operator would never send code again. His telegraph key would\nbe silent.</p>\n<p>This tradition has been carried on among amateur radio operators or\n&#x201C;Hams&#x201D;. This is also a close knit community of people. While some still\nuse Morse code to communicate (Referred to as &#x201C;CW&#x201D; for continuous wave),\nthere are many other forms in use, including voice and digital modes.\nBut regardless of how we communicated with them, when we lose one of our\nown, we still say they are SK. Silent key. No longer able to\ntransmit.</p>\n<p>Organizations like the American Radio Relay League (ARRL) and QRZ.com\ntry to update their records when a Ham passes away. There are also\ndatabases like silentkeyhq.com which keep records and memories of\ndeceased operators.</p>\n<p>So, it is with great sadness that I have been updating the records\nfor my close friend and mentor KV4YD. Thank you for your friendship and\nsupport, and for sharing your wisdom over the years.

This practice may occur among people who desire to\nlose weight, gain muscle mass, or maintain a healthy lifestyle. Advance\npreparation can serve to standardize food portions. Meals preparation\nare fully cooked. Meals may be prepared in small containers such as\nTupperware, and are sometimes labeled and dated to remain\norganized.<br />\n</li>\n</ul></li>\n<li><strong>Source:</strong> <a\nhref=\"https://en.wikipedia.org/wiki/Onion\">Onions</a><br />\n\n<ul>\n<li>Freshly cut onions often cause a stinging sensation in the eyes of\npeople nearby, and often uncontrollable tears. This is caused by the\nrelease of a volatile liquid, syn-propanethial-S-oxide and its aerosol,\nwhich stimulates nerves in the eye. This gas is produced by a chain of\nreactions which serve as a defence mechanism: chopping an onion causes\ndamage to cells which releases enzymes called alliinases. These break\ndown amino acid sulfoxides and generate sulfenic acids. A specific\nsulfenic acid, 1-propenesulfenic acid, is rapidly acted on by a second\nenzyme, the lacrimatory factor synthase (LFS), producing the\nsyn-propanethial-S-oxide. This gas diffuses through the air and soon\nreaches the eyes, where it activates sensory neurons. Lacrimal glands\nproduce tears to dilute and flush out the irritant.<br />\n</li>\n<li>Cooking onions and sweet onions are better stored at room\ntemperature, optimally in a single layer, in large mesh bags in a dry,\ncool, dark, well-ventilated location. In this environment, cooking\nonions have a shelf life of three to four weeks and sweet onions one to\ntwo weeks. Cooking onions will absorb odours from apples and pears.\nAlso, they draw moisture from vegetables with which they are stored\nwhich may cause them to decay.<br />\n</li>\n<li>Sweet onions have a greater water and sugar content than cooking\nonions. This makes them sweeter and milder tasting, but reduces their\nshelf life. Sweet onions can be stored refrigerated; they have a shelf\nlife of around 1 month. Irrespective of type, any cut pieces of onion\nare best tightly wrapped, stored away from other produce, and used\nwithin two to three days.<br />\n</li>\n</ul></li>\n<li><strong>Source:</strong> <a\nhref=\"https://www.momswhothink.com/what-are-dump-dinners-and-which-recipes-are-easiest/\">What\nAre Dump Dinners, And Which Recipes Are Easiest?</a><br />\n</li>\n<li><strong>Source:</strong> <a\nhref=\"https://www.tasteofhome.com/collection/slow-cooker-dump-dinners/\">55\nDump Dinners for Your Slow Cooker</a><br />\n</li>\n<li><strong>Source:</strong> <a\nhref=\"https://www.pinterest.com/\">Pinterest</a><br />\n</li>\n<li><strong>Source:</strong> <a\nhref=\"https://www.amazon.com/mug-warmer/s?k=mug+and+warmer\">Mug\nwarmers.</a><br />\n</li>\n</ul>\n<p>This work is licensed under a <a\nhref=\"https://creativecommons.org/licenses/by-sa/4.0/\"\ntitle=\"CC-BY-SA 4.0 International\">Creative Commons\nAttribution-ShareAlike 4.0 International License</a>.</p>\n',391,0,0,'CC-BY-SA','Bumble Bee, Meal Prep',0,0,1);
