Copper Catch

Concerning the earthquake predictions using AM radio reception comparisons, try this thought on for size: The friction or stress underground creates a static charge. Similar to rubbing a sweater and touching a doorknob. This static charge when spread over a large area could induce a very slight electromagnetic field, like listening to lightning crackly over the radio when an electrical storm is near. Only so slight as to be nigh impossible to measure. This natural charge could influence the reception by altering the radio waves as they pass through the atmosphere. Aircraft with modern navigation and computer systems have HERF protection through shielded wires and numerous grounds attached to the wire bundles passing through the structure, as even the slightest stray field can dramatically alter data as it is passed from computer to computer.

My suggestion is to try this:

• Fabricate a grounding wire approx., 2 feet long, of single strand copper. Take a 18 inch piece of copper pipe and drive it into the ground with a provision for attaching one end of the ground wire securely to it.
• Find a metal contact place somewhere on the radio frame (possibly at the negative pole of your battery cluster) where you can secure the other end of the ground. do not attach this ground to the antenna!
• When the reception anomaly is suspected, hook up this arrangement and see if a difference is found between the 2 configurations.
• If there is a difference, it could be measured with a device called a "megger", short for megometer. These are available at any well supplied electronic supply shop.
• Drive a ground pole into the earth and stretch an un-shielded wire from it to a point several feet away, say, suspended from a tree limb. the wire should have 10 loops like this---------O---------- wound into it at the middle. Like an extension cord hanked with both ends dangling. The megger is passed through the center of the loops and around the outside radius when taking a reading.
• These loops multiply the actual reading into something the instrument can detect. just take the reading and divide by 10 to get the actual.

This sometimes works when looking for stray EMF around high tension lines. I agree it's off-the cuff, but it costs almost nothing but time and may yield some surprises. Let me know what ya'll think.
