商品描述

Do you want to be able to receive satellite images using nothing but your computer, an old TV antenna, and a $20 USB stick? Now you can. At last, the technology exists to turn your computer into a super radio receiver, capable of tuning in to FM, shortwave, amateur ham, and even satellite frequencies, around the world and above it. Listen to police, fire, and aircraft signals, both in the clear and encoded. And with the book's advanced antenna design, there's no limit to the signals you can receive.

Combine your desktop or laptop computer with easy-to-find, Software Defined Radio (SDR) equipment, and tune in a wide range of signals in no time at all. Then, go one step further by converting a Raspberry Pi into your own dedicated SDR device.

SDR USB dongles are usually designed to receive and decode high-definition digital television broadcasts, but the rising popularity of SDR has led to several of these devices being specifically made for - and marketed to - the software radio crowd. With step-by-step instructions, you'll have no problem getting everything up and running on both Windows and Linux.

The antenna is the final piece in the SDR puzzle: Which antenna do you use? What shape do you need? How big does it have to be? And where do you point it? Get all the answers you need and learn what's possible when it comes to picking out or building an antenna. And if you're not particularly handy, don't worry. You can use an old-school set of rabbit ear antennas without too much modification.

Discover the fun of this growing hobby and then open your ears to the hidden signals that surround you.

What You Need:

You will need a relatively recent computer or laptop, running either Windows or Ubuntu Linux. You can also use a Raspberry Pi. All of the software necessary is free and open-source, and the book describes in detail where to get it and how to install it, depending on your operating system.

商品描述(中文翻譯)

你想使用電腦、一個舊電視天線和一個價值20美元的USB插頭來接收衛星圖像嗎?現在你可以了。終於有了這項技術,可以將你的電腦變成一個超級無線電接收器,能夠收聽全球和地球上方的FM、短波、業餘無線電甚至衛星頻率。聽警察、消防和飛機信號,無論是明碼還是編碼。而且憑藉本書的先進天線設計,你可以接收到無限的信號。

將你的桌面或筆記型電腦與易於找到的軟體定義無線電(SDR)設備結合起來,立即調諧各種信號。然後,再進一步將樹莓派轉換為你自己的專用SDR設備。

SDR USB插頭通常設計用於接收和解碼高清數字電視廣播,但SDR的日益普及導致有幾款設備專門為軟體無線電愛好者製造和推廣。通過逐步指導,你將毫無問題地在Windows和Linux上運行一切。

天線是SDR拼圖的最後一塊:你要使用哪種天線?需要什麼形狀?有多大?應該指向哪裡?獲得你所需的所有答案,並了解在選擇或建造天線時的可能性。如果你不太擅長手工,也不用擔心。你可以使用一套老式的兔耳天線,不需要太多修改。

發現這個越來越受歡迎的嗜好的樂趣,然後打開你的耳朵,聆聽你周圍的隱藏信號。

你需要一台相對較新的運行Windows或Ubuntu Linux的電腦或筆記型電腦。你也可以使用樹莓派。所有必要的軟體都是免費且開源的,本書詳細描述了在不同操作系統上獲取和安裝軟體的方法。
