Hi Stefan, Indeed - but for an existing design, the through-hole parts are favoured (just flip the JFET around if the pinout is Gate-Source-Drain instead of Drain-Source-Gate as for J310 vs BF245). I
Hello Wolf, Thanks for keeping your system available. It is one of the few available VLF RX stations that provide a stream, very important, together with Pauls work to make use of it. I want to provi
