This produces a functional and well packaged SDR. There are two antenna inputs, 100KHz-30MHz and 25MHz-1.7GHz. The unit is powered and operated through a mini USB connector. You are required to dismantle a USB SRD dongle, attach the board in a cutout on the main PCB, solder SMD components, wind your own coils, and solder 24 awg magnet wire to 0.5mm pitch pins. This will require. The directions are a little vague and hard to understand at some points. Read the instructions and make sure you can perform everything required before purchasing.
Please, I would appreciate if you explain to me where is the plate that goes in the middle, where the toroid is connected to the integrated one. The plate is incomplete and it does not help me. What I'm doing to get what I need. I would appreciate answering me, as soon as possible, because I am very angry and I feel cheated. Thank you, I wish you a good day, but tell me what happens with the circuit that I lack.
All capacitors are not marked, three sets off three - roll the dice?
Radio SDR full band. It's not easy to assemble I had to use the microscope for the small toroidal coil. To use this key with SDR sharp software you must use version v1.0.0.1583.Thanks Banggood
this radio software comes like the picture. it is not ready to use. it comes without the instructions and the software (I found the link at Banggood answers).
Nice kit but, toroïdal transformer is extremely hard to solder without proper microscope and solder iron.
It comes in a bag with anything you need to assemble a Very Good software define radio receiver, who covers the majority of radio communication bands! Anything you want to receive from 100KHz to 1700MHz is here. With slim nozzle to the soldering iron, a magnifier glass and some free time to spend, I managed to complete the assembly of the kit in less than one hour. The only difficult part is to solder the transformer to the IC pins, surely take some more time but is doable. I suggest you use flux and after the soldering of the components clean the remaining resin with acetone and a used toothbrush (especially in the around the IC area). I found this Kit an Excellent exercise for beginners who want to learn how to solder SMD’s. Delivery Time was fast and Seller’s service was VERY GOOD!!! So YES! I strongly recommend this product and the seller!
les composants sont emballés dans un sachet anti statique et l'antenne n'a pas été tordue pendant le transport.
O pacote chegou em boas condições. Começou a ser construído imediatamente. Este kit não é definitivamente para iniciantes. A questão fundamental é soldar fios aos pinos 4 e 5 do chip RTL 2832. Você precisará de pelo menos uma boa lâmpada de lupa e mãos seguras. Finalmente, consegui fazer isso. Mas estava no limite. Depois disso, instalei o software SDR. Funciona como um encanto nas frequências UV. Para o HF, você precisará de uma boa antena. Escolhi comprar um MLA-30, que custa o dobro do preço de um SDR...
Ziet er leuk uit alleen jammer dat er geen gebuiksaanwijzing bij zit. Heb hem nog niet in elkaar gezet. De gebruisaanwijzing blijkt bij hun site op internet te staan. Maar gezien de prijs lijkt het mij een leuk en eerlijk product.
