I've been reading up on radio transmitters and have decided to build one. I'm going for a small simple AM transmitter with maybe a range of a 100ft or so. I'll probably go with a Colpitts design but my question is what kind of inductor do I need? Does it matter? I see dip, color wheel, ferrite, torrid, and special RF inductors. What is the difference? I know some are rated at higher currents and Q values but what would be a reasonable max current to expect going through the inductor in my transmitter? I'd rather not build one myself. Would these be usable **broken link removed** ?
Thanks.
Thanks.
