I made a smale supprint with only the sx48 on. You can find de pin numbering in img2. That print I can plug on the main print (img1). This way I can swap sx48 without much soldingwork. One thing I'm not shure off. Thier are several pins gnd and vdd on the sx48 ship. (see ex pin 1,7,21,35 for vdd) I made for all the connection to my power supplie. Same for gnd. Is that necassery??? Is that casing the problem?? I don't know. Can you give mee a look at the schematic and give me your findings/remaks .... Thanks in advance.
