LCQ-Meter HW version 2.0 bottom view assembled with Electronic Assembly Display and Schurter switches.

 

Sames as above top view.

 

 

LCQ-Meter HW version 1, works fine but some improvements possible.

 

LCQ-Meter Prototype, worked quiet well for non-SMD assembly (there was also a breadboard version, but unfortunately I do not have a picture of it; off course functonality was limited at midium frequencies).

 

LCQ-Meter version 2.0 used to measure high performance magnetic loop; very portable measurement!

 

Inductance and Capacity of magnetic loop; can it be easier to measure?

 

Wow! Q = 523 at 7.2 MHz; there is large influence from the environment; loop turned 90 degrees drops Q down to 300.

 

 

W1JGH built the LCQ-Meter into a Plastibox G from Bud Industries. I wish I would have seen such a nice and affortable enclosure before!

 Here is a nice build from DL9AJ:

 

...happy to post more from other builders!
