Thank you for your answers Indeed I found tons of information about this achievement. I also saw the Gerber files of the PCB, I will integrate them in kicad to see. However, I did not find any Kicad schematic files. if you have one, if you can make it available. After actually the simplest is to buy one, but I like the manual construction.
Right now I¡¯m just gathering information. (e.g., purchase modules and retrieve components, purchase components, etc.) Basically the nano was enough for me, but I don¡¯t know if we can add a tracker) It¡¯s for radio, so 50MHZ max I will also look at the mentioned sites (ex VK3PE) Funny thing is, I¡¯m not an Ham radio man, but I¡¯ve always been into electronics.?It will occupy the long winter night You see some post on the ISO Group Ubitx I¡¯ve redesigned a complete Ubitx with Kicad and more options
