You are forgetting the 90 MHz of spectrum between the top of Ch 6 (88
MHz) and the bottom of Ch 7 (174 MHz). It IS, indeed, a continuous
function, the impulse noise DOES decay gradually with increasing
frequency. There is a similar break between the top of Ch 13 (216 MHz)
and the beginning of the UHF channels (around 500 MHz).
