Yes, i know that now. i just couldn't believe you'd use more vias than
needed, esp. when it is so obvious. The ground planes explain that.
About the LC meter, it is that one with the morse code, i actually looked
at that before i bought the benchtop RLC meter. But i decided the morse
code is way too awkward for me. A LED display will sure make it a lot
better. Well, too late now for me, the meter is bought. It also does
parasitic parameters and is very accurate, so it was still a good buy.
