The k2 rf board shows c4 and t1 quite close together. Even with a magnifying lamp i cannot tell if the one lead of c4 and the clip-in mechanism of t1 are to be soldered together. This is the lead of c4 which goes to ground. What is the story here? Also before i go any further, the "clip-in" mechanisms which hold these on the board are to be soldered arent they? thanking all in advance john
