I have noticed that a weak station close or below noise is often much >easier to copy if one walks away from the receiver. ..... I heard my first eme signal by putting my earphones in a large crystal (cut glass) dish and standing back about 5 feet or so. This was a trick that was taught to me by a chap who earned his living copying CW as "piece work" so he had an incentive to listen for stations calling. The most critical need was to keep moving around, physically, until you found the "sweet spot" were you could hear the really really weak signal. I demonstrated this capability some years ago while working with water based ground reflection gain on 2 Meter eme - a visitor told me the "sweet spot" was probably were the two ears were copying best was were there was a phase shift in the audio approaching 90 degrees thus giving what we now know is the extra sensitivity of the I and Q channel reception condition.
