Re: Harmonics and Relay Replacement

 

Hi Jim, or Raj, or ¡­.
?
I have trouble with reproducibility on lower numbers with my recently purchased LC200.
?
Butt when I see people that know what they are doing having good results, I'm inclined to ask whether there is anything special, or for that matter, just how are you measuring the lower value inductances, figuring based on past experience that I may not have yet acquired the "knack."
?
Thanks, Scott ka9p
?

Hi Raj,
Funny, I have a DE-5000, LC-100A (real cheap one from eBay) and the AADE
and they all agree within less than 1 percent. You might have a bad
crystal oscillator on the uP in your AADE? Or maybe I just got lucky as
I was given my AADE by a friend, several years ago. Not sure where he
got it.

The biggest surprise is how accurate the very inexpensive LC-100A has
been. I think I paid $9.95 USD with free shipping for it.

Jim, W0EB
