Medium Wave AM radio has its faults, but one that should have been fixed by now is the polar directivity of the signal which can discourage listeners needlessly.
Here's an example. This shelving unit here in the kitchen was custom built for this location... up top is a Panasonic table radio neatly set against the east wall. Some stations come in well, but others would require twisting the radio at a sloppy looking angle so the loop antenna in the back is favoring the north-east.
I happen to know how to swivel, turn and angle radios for best reception, but most people are unaware of it or are opposed to having their radio out of place.
We've got to start immediately to design antenna systems that will fill in the nulls and make AM radio optimize no matter which way the radio is pointing.
Engineers have gotten lazy after decades of success and now we stand to lose the AM legacy as stations disappear because radios are facing the wrong way!
No more slacking!
