Tony The diameter of the wire has absolutely NO importance. Excepted that you won't be able to wind your core if the wire is too thick. The final inductance do not depend of the wire diameter (or its influence is far less important than variations of the permeability of the ferrite itself). So, you only need a wire "approaching" the theorical 33 SWG.
If you have some time to spend on this very interesting "detail", try to wind say.... 10 turns on a core with a 3/10th wire , then 10 turns with a 5/10th wire (with the same spacing) and compare the resulting inductances. After that, make the same measure with 11 turns. You will see that the supplemental turn has more influence on your inductance than the gauge of your wire. If you do the test with different cores of the very same reference, you will also see that dispersions of characteristics of the "AL" factor of the ferrite is sometime very important between different cores. For this reason, it is sometime more useful to verify the final inductance with a RLC meter.. My 2 cents Marc, f6itu A good working kernel doesn't allow a program crash unless it says please Traduction : Da Power Fantudjû, RuleZ Tartiflette
