... Huh? Yes, he is well into RF and construction techniques will be different. But while there are advantages to air-coil cores, their use in recievers went out with hollow state detectors. I think that Coilcraft, API-Delavan, Pulse, etc. would be surprised to hear them. Although I'd grant you that you don't typically find many air coils in mass-market consumer electronics anymore, they're still used all over the place in industrial and military design... where I work we buy tens of thousands of the things every year for radio receivers! Plenty of articles appearing in QEX and on-line also use air-core coils, since it's a pretty fast and you can, of course, get whatever value you want with no "minimum purchase" quantities. ---Joel Kolstad |
