winding sheilded coils
 

Could someone help me to determine how many turns I would need to make
0.68uh and 0.2uh coils, I am totally lost with math so if some kind person
could just give me the number of turns,that would be great the coils in
question are the size that you see in most portable radios
thanks Mark

It depends on the frequency (you need to make sure that the correct core
is used), the core and the size.
