I have just completed several homebrew chokes, the question is what is
the most effective way to use a dip meter to check these chokes for
resonance. I have tried several coupling methods, but the dips change
depending on how you couple the dip meter to the choke. I seem to get
very sharp 30>200mhz dips, but the <30 mhz seem weak. I am using 2 turn
coupling on the end of the choke, there is a 5" lead between the
coupling turns and the choke base. I noitice that if i direct couple the
dip meter to the base of the choke the dips change freq. Maybe its just
my pathetic Jap Dip meter. Any suggestions would be appreciated.
