Hello Daniele, It can be easily done, using the "3 dB method".This method does load the LC circuit very lightly, so the measured Q is close to the unloaded Q. For a further read, I suggest W7ZOI's article here: http://w7zoi.net/2faces/twofaces.html This is also an interesting read: http://w7zoi.net/coilq.pdf 73, Roelof, pa0rdt |
