      There is nothing special about the  AADE. The circuit is identical to the scores of PIC and Lm311   based kits

       When it comes to very low inductances for RF, all the LM311 and PIC based L meters are not that accurate. For C , may be another story !

      Chris, AADE makes a LC meter that is very accurate.  I think that Neil 's
      name for AADE is almost all digital electronics (?)
