This SDR was designed from some of my experiments so far, from various sources with improvements here and there so that I can get maximum results.

LO using Si5351A which is controlled by Arduino Nano produces a frequency that is wide enough Max 160Mhz, of course allows us to make Exciter up to 10M band. LO = work freq x 4.
My BPF takes from the us5ncj design using an already-built Inductor, so it is practical without the need to roll.
Parts of TX, RX, and RF Preamp are not much different from the SDR series in general such as Avala, Mchf, tulip and others. Only, I choose which is easy, simple, and the results are maximum.
RF Power Amplifier is intentionally not in this Kit, you can combine it with any RF Power. And the output of this Exciter is quite small at 10-50mW. In practice, you can use the former RF PA FT-80C, FT-180A or the other.

  • 7 Tips On How To Make Your PCB Entries Stand Out 1.Choose the appropriate color of soldermask and silkscreen for your PCB project. 2.In addition to the PCB images generated by our website, you can upload more photos of the project. 3.The more detailed project’s description is, the better judges and other makers understand it. FYI, it is a good idea to insert a video, currently our platform supports “YouTube” and “Vimeo”. 4.Open for Gerber download and BOM download. 5.Frequently share your entries to your social media and some open source forums, allowing more people to vote your entry, like it, download the Gerber file and also place orders for your work. 6.After uploading your entry, please constantly pay attention to its page. There will be other makers asking questions about your PCB project, and timely responses and multiple interactions will be additional points. 7.We also encourage you to upload more entries about Assistive Technology (AT) by supporting a special award, “AT Maker Prize”. Hope that more makers could contribute to the promotion of Assistive Technology.
