I'm looking to buy some inductors, axial or radial ones. What I need to know is the difference between measured dc current and ac current. Modeled in multisim, the max dc current through the inductor is about 1mA but the max ac current approaches 1A. I know inductors have max current values, so...

I'd like to make it broadcast over commercial AM so that it can be picked up by a home radio. I'm not too concerned about FCC as it won't be broadcasting off my property and it's really only for learning purposes. So about 0.5Mhz to 1.6Mhz. If I understand correctly, I should pick a SRF value...

I'm trying to design a AM transmitter using a colpitts design. I see many different types of inductors available for sale, smt, torrid, dip, ferrite core, iron core, etc... Which one should I buy? I know they have different Q values and max current. What do you think the max current would be for...
