Hi, I'm thinking about building an automatic tuning controller for my magloop. It could search for a current max, but this can be a challenging task.
It's probably easier to look for a capacitor position where the phase between voltage and current crosses the 0, with reasonable deadband for stability. This is probably easier to find than a current max. What I'm looking for is a working example, since my experience is not enough to design the whole from scratch. I found already some commercial devices: http://wimo.de/magnetische-loop-antennen_d.html http://q-mac.ru/en/qmac_mx9027.html Joe K3JLS is working on MLC, too (was www.k3jls.com/mlc.html, should be put live when Joe's project is ready) A nice newsgroup conversation on the same subject: http://newsgroups.derkeiler.com/Archive/Rec/rec.radio.amateur.antenna/2005-10/msg00268.html Does anybody here use an automatic, phase detector based magloop tuner? 73!
