The height is the issue, here.
At 5kw, the signal would not be picketting as much at authorized height. At 262ft., yeah, the multipath is evident making the signal appear worse than it really is.
Remember, Empire signals are only 6kw.
Correct. Look at it this way:
To maintain a protected 70dbu contour at a chosen distance, power must be reduced by the square of the height increase.
For example, a C2 with 50kw at just under 500 feet would be reduced in power to 12½kw at a kilofoot and about 3kw at 2 kilofeet. Apples are not oranges, however. For most points within the line of site, the 50kw station will penetrate buildings better and sound stronger on inadequate receivers. More importantly though, the higher station will sound cleaner with less bouncing around. This is why stations always go for the highest perch in the centers of their markets, not to mention savings in equipment and the power bills.
Unfortunately, band openings discriminate harshly in favor of the higher powered stations. WQCS will get into WDNA's area much worse than the opposite and I expect WUFT (superior height and power) to hurt WSMR more on cold nights than the opposite.
