Hi Tony. I'm listening from Northen Virginia, how about you. Yes
there were times when 740 was coming in during the morning rush hour!!!
That's what I love about dxning...it is never constant!!! When my
favorite AM 740
disappeared some other station popped
in...barely audible, but it was there.


Sorry I didn't mention it in my first post, and you evidently missed
my follow-up one: I'm in the SW corner of Michigan. The faint station
you were hearing on that frequency was likely KRMG from Tulsa, OK. On a
good winter night, it clashes annoyingly with CHWO where I am, though
CHWO usually wins. It's no problem past KRMG's night operation time, as
they then drop to 25,000W.



It is not the power drop, it is the fact that KRMG is extremely
directional at night in that direction. 25 kw is huge power, and a change
from 50 kw to 25 kw would hardly be noticed, as it only effects the
station's field strength by 25%.


(Shrug) I can only tell you what I hear at my location during the
winter months. When darkness comes to the Central time zone, overlap from
KRMG falls off sharply here.

And that is because KRMG goes directional at night, sending nearly all the
signal away from you. It is not because they reduce power.
