Ham Radio Is Alive and Well

為了解決Ham radio band的問題,作者Drasch, Gary L. 這樣論述:

Ham Radio is Alive and Well, as reviewed in QST Magazine by Rick Lindquist, WW1ME, "is the expanded edition of what you might see under "ham radio" in Wikipedia. As the subtitle suggests, Drasch's compendium offers the largely traditionalist view of a ham radio Rip van Winkle of sorts, who, after be

ing first licensed at age 12, broke away from the hobby for several decades when school, family, and career took precedence, and then, roused by a ham radio friend, dove back in about a decade ago ―as he concedes, not quite where he left off all those years ago. So, Drasch is at once a veteran radio

amateur and a relative newcomer, although his intervening career involved electronics. After establishing that hams "are still doing that," Drasch's narrative incorporates a bit of "then-and-now" comparison and contrast that veteran radio amateurs will be able to relate to. His overarching emphasis

is on conventional HF operation, from DXing and contesting to popular operation modes. One useful resource for newcomers is the one that explains "Ham Radio Speak," defining some of that confounding jargon we OTs (old timers) have been using among ourselves for decades when chatting about the lates

t DXpedition over coffee or, perhaps a couple of 807s (beers). He includes as well a list of abbreviations that one would use on CW or perhaps on some digital modes, and a few Q signals. Black-and-white photographs are sprinkled liberally though out the book's chapters, to illustrate a point or just

to complement the content. Something in Ham Radio is Alive and Well will appeal even to veteran hams, although I'd see the primary readership as newcomers, especially, those whose Amateur Radio arc was interrupted mid-course, but then, like Drasch, got back into Amateur Radio rather late in the gam

e. Gary Drasch acquired his radio amateur Novice license in 1960 at age 12 and his General class license at 13. After graduating from high school, he attended the Milwaukee Area Technical College, and received a diploma in Electronics, Radio, and Television. He continued his education by earning a

two-year certificate in Radio Communications. After graduation, he obtained an FCC commercial First Class Radiotelephone Operator License. It was considered the pinnacle of licenses as it was required to operate and maintain TV/radio broadcast transmitters at the time. His electronics career began

as the owner and operator of a TV, audio, and communications, sales and service business. He closed the business after eighteen years and spent a short stint in the radio pager business before joining the John Fluke Manufacturing Company in 1985 as a Sales Engineer. He retired 24 years later at the

age of 62 and immediately returned to ham radio. He became totally reabsorbed into the hobby and attained his Extra class radio amateur license. DXing, contesting, antenna experimentation, and home-brewing accessories is his passion. Thus far, he has worked 304 countries (entities) and 1335 band slo

ts. He earned the DX Century Club award using mixed, CW, phone, and digital modes. He captured the Worked All Continents award and the Work Antarctica Callsigns Award. He has Worked All States in all three modes and received the Triple Play award. Memberships include the American Radio Relay League,

The Society of Midwest Contesters, and The Greater Milwaukee DX Association. He is also a member and Past President of the Ozaukee Radio Club. Gary and his wife Chris have been married for 45 years and live in Port Washington, Wisconsin. They have two adult children, Jennifer and Andrew.

具有可切換式新型變容器LC壓控振盪器之2.4GHz次取樣鎖相迴路

為了解決Ham radio band的問題,作者李柏翰 這樣論述:

本論文提出一個應用於2.4 GHz ISM band的鎖相迴路設計,內含兩個部份:第一部份為鎖相迴路的其中一個子電路壓控振盪器設計;第二部份為完整的鎖相迴路電路設計,將子電路全部整合起來,以電路的操作電壓均為1.8伏特下去做設計。在第一顆壓控振盪器的部份採用新型的變容器來當作可變電容,並且搭配開關使整體的電容變化增加,所以電容整體的變化可以從0.82 pF到1.66 pF,在量測的部份整體的頻率可調範圍為2.59 GHz到2.15 GHz (18.6%),比較和模擬時的2.792 GHz到2.2 GHz (23.7%)。相位雜訊在最好的部份可以到-121.56 dBc/Hz和模擬時的最好相位

雜訊是差不多的,整體的功耗在量測時為6.89 mW。 第二顆鎖相迴路採用次取樣鎖相迴路設計,包含了兩個迴路:一個為主迴路(core loop)和另一個為頻率鎖住迴路(FLL, frequency locked loop),其中主要迴路採用了次取樣的技術,在採用次取樣的技術有兩大優點:第一優點為相位偵測器和充電泵的雜訊不會隨著除頻器的N上升而雜訊跟著提升N^2倍;第二優點為當頻率鎖上時此時不會提供除頻器的雜訊。本次的參考訊號為37.5 MHz,在直流操作電壓上均為1.8伏特而整體的功耗為8.14 mW,輸出功率為-2.11 dBm,相位雜訊在1 MHz的偏移處為-88.78 dBc/Hz;在1

0 MHz的偏移處的相位雜訊為-120.8 dBc/Hz。
