GenesisRadio G11 SDR: A CONTEST WINNING Transceiver!

با سلام

طرح يا كيت ديگري از راديوهاي نرم افزاري باقيمتي مناسب(299دلاراستراليا) و برد نيمساخته (قطعات ريز نصب شده اند) كاربرد كامل و توان ايده آل (10وات) تقديم مي گردد

افرادي كه مجوز راديو اماتوري دارند و پروانه ايستگاه هم دارند خودشان مي توانند اين راديو را سفارش داده وارد نمايند يا از شركت هاي مجاز داخلي سفارش دهند

Building and operating your own equipment is still the ultimate goal of amateur radio, and Genesis is exactly that: Fun to build, fun to operate! There are so many things you can do with your Genesis: from regular 2-way Morse contacts, phone, digital modes like PSK to RTTY or WSPR - Truly, the list of activities for which you can use your G11 is practically endless! If you're into QRP, DXCC chasing or serious contesting, the G11 will deliver unparalleled performance you won't find in much more expensive analog radios. Do not underestimate G11 based on its low price - This CONTEST WINNING radio is a serious performer that will give you many hours of on-air enjoyment!

The G11 is a "hybrid kit": for your convenience, all the difficult to solder SMT components (over 600 of them!) are factory pre-assembled. Your task is to assemble 50-60 large trough-hole components and to wound a bunch of toroids. The entire assembly takes 8 hours. Order your kit now! Price: AUD$299 plus delivery.

Band coverage: based on your filter selection, the G11 can be configured to operate as a 10W+ SDR transceiver on up to 5 selected HF bands. Alternatively it can be set as dedicated LF SDR transceiver for either 137 KHz or 500 KHz or as a wide band LF receiver. For details and specification see links below.

SDR يا راديوهاي نرم افزاري

با سلام و آرزوي سلامتي دوستان

مطالبي چند راجع به اين راديو ها ديدم كه برايم خيلي جالب و قابل تامل بود

قيمت مناسب

كيفيت ايده آل

پهناي وسيع باند

قابليت رويت اطراف فركانس كاري

امكان ضبط مكالمات و امواج

نمايش پهنه امواج (شنيدن كي بود مانند ديدن)

انتخاب انواع مدولاسيون با هر كيفيت

كار چند باند همزمان

.....

اين مطالب مرا بر آن داشت چند ايستگاه و شركت و طرح در اين زمينه معرفي و مطرح نمايم

Software Defined Radio

سلام

مطلبي خواندم از راديو هاي نرم افزاري كه همانطور كه از اسمشان پيداست بجاي المانهاي معمولي راديو و خازن متغيير و بوبين و اي اف و ....

از نرم افزار استفاده مي كنند

درواقع اين راديوها مثل نوسانساز ها و برنامه هاي صوتي كامپيوتري فركانس واقعي نيستند و اطلاعات هستند كه در ابتدا و انتها تبديل به انالوگ شده و قابل بهره برداري مي شوند

اين طرح راديوي نرم افزاري است كه از طريق كابل يواس بي به كامپيوتر متصل شده و از طريق انتن به فضاي بيرون وصل ميشود

بعد از نصب نرم افزار شما راديوئي از 10مگا تا 6گيگا هرتز با تمام كارائيها منجمله انواع مدولاسيون و فيلتر هاي مختلف اي اف و گيرنده پهن باند با پوشش 20مگاهرتز خواهيد داشت

انتن استاندارد اين راديو تلسكوپي و مدل ANT500 مي باشد
