Doh! This had never occurred to me for some reason. At 270 watts, in a
city as RF noisy as Washington D.C., I can't imagine that they'd have a
huge listenship at night in the first place - so the financials probably
don't make sense to maintain the C-Quam at night.

A 5 watt nighttime station on AM 74 in Cambridge, Mass. does cover Boston
and Cambridge quite well..

Why is Washington DC so RF noisy?

markets that *barely* cover their C.O. at night. And turning down all
those pip-squeak stations at night *just* might lower the noise floor
for everybody else...

Correct. It might. However these stations are under the impression that
they have listeners even during the daytime - period.
