Gang,
FYI, I had build a L/C meter appeared in "Electronics Now" last year
(or may be 1995?). It uses a 16C61 PIC chip and an LCD display. It boasts
self-calibration and an accuracy of 2%. I decided to build one from scratch
(accodring to ham's spirit, etched my own circuit board, programmed my own
PIC chip, etc. Not to metion, build my own programmer for the PIC chip). It
works FB just like the author said in the article. For you homebrewer out
there, this is a must for identifying/making your inductors and capacitors.
The author did offer for sale the meter in kit form and the price is
reasonable. He even put the source and HEX file on EN's ftp site. I
downloaded the files and found that they are for the two-line type of LCD so
I modified it to work for my one-line by 16 LCD and it works ok. In
addition, I replaced the 16C61 with a 16C84 (EEPROMtype for easy
prototying). I would be willing to help if anyone is interested in such a
project.
I had been reading QRP-L in digest form lately as I was busy moving
and still don't have an antenna up, so no rf activities for me.
Later and 73's
