      Look what I found ! If what they claim is correct, both the price and performance from small rf coils is the ideal

      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 !
      End Quote.

      as I wound each toroid for my Ensemble RX II, I measured each one and found the measured inductance to be within 1-2% of what the build plans said they should be. I doubt that was a coincidence.

      I also measured most all of the capacitors and found them equally within tollerance.

      Why would you say the pic/comparator based meters are inaccurate??

      What kind of accuracy do you believe one needs to build a radio reciever?

      For me... the $27 (delivered) I spent on my ebay LCR meter (see other recent thread) is one little piece of test equipment I am VERY pleased with.

      The re-assurance that I had not made an error while winding the toroids was well worth it. It made building the kit more enjoyable. And now I can be more certain when I dig through my junk box I can test/verify that old capicator or inductor.

      I regularly work with test equipment at work that cost 20,000 to 40,000 dollars, But for the Radio hobbiest I think the pic based LCR meters are actually VERY adequate.

      just my .02
