I've been experimenting with AM loop antennas, they are directional, and you can "null out" staions by turning the antenna. I have three that are about two feet on each side, and one that is four feet on each side. I use varactors diode to resonate the antenna. I use the antenna to get rid of mid band noise on the AM band. I turn the antenna so it's broad side to east and west.

I've been experimenting with building my own AM receiver, and just found a source for LM3820 chips, which I ordered last night. I need a receiver that is voltage tunable, and covers am, and at least some shortwave. I made one cricuit last weekend using an NE602 as mixer/oscillator, the MC1350 as the IF amp, an FET detector, and an LM386 audio amp. It covered AM, and 49 through 31 meters. That worked on the breadboard, but not when I put it on perf board. Must be my layout technique!

To me, it seems like it's the computer dorks that want, and think AM is a dead format. They want nothing but internet crapola. Everything is going digital because it's a cheap, albeit crappy, way to do almost anything.
