Just a guess, but they may use 2 different transmitters...one for days, and
one for nights, given the large discrepancy between operating power levels.
Heck, the control circuits of the high-power 50 kW xmtr probably use more
than 270 watts of AC power just running in standby !! In any case, it may
be as simple as the low-power transmitter not being equipped with a C-QUAM
exciter (or it not being in working condition) ..... and judged not to be
worth the $$ it would take to repair/replace/install in the first place.



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.

Which begs the question: why don't these stations just throw in the
towel for the after sunset crowd? Are they really generating enough
revenue with their non-existant nighttime numbers to justify the AC for
the xtmr? I can't count a half dozen stations in the D.C./Baltimore
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...

How do AM stations with sunset flea power price their overnight
inventory? Surely the sales team doesn't price these spots the same as
a daypart spot, right?

WHVO in Hopkinsville KY drops to 24 watts and has a decent signal which
covers about 6 - 8 square miles.

That's providing there's anyone in that tiny area. This may work in a
high-population density city like Boston/Cambridge....

How crowded is Hopkinsville, Kent.?

[ Moderator's note: I have family in Hopkinsville, KY. The area is fairly
well populated... Fort Campbell straddles the city and state lines, with
half of the base sitting in Hopkinsville, and the rest sitting in Clarksville,
Tennessee. The base itself is pretty big. ]
