I have been reading about Tesla and dipole senders. A dipole sender is like a long pole with sends out a signal at both ends. Tesla sometimes grounded his radio dipole senders so that one sending dipole was a ground. Likewise, he grounded his radio receivers. I live in the mountains and get terrible radio reception. All I want is decent AM reception. My understanding is that an AM receiver does not depend so much on an antenna as FM. In an effort to improve AM reception, I have attempted to ground the receiver. But all the radios I have are "modern" and have no ground provisions built into to them and have a plastic case. A tech-type suggested using a car radio, grounding it, and buying a transformer to convert AC into the appropriate wattage of DC for the radio. An auto radio uses the car's metal frame as a ground so this fits right in with my concept. Question: Would doing the above improve my AM reception?
