Fw: MetroWest signal strengths (from V-soft Web site)

These pretty much bear out my own experience when I lived in the 
western edge of Wellesley from 1986-96, and when I go down there to 
visit relatives.  In the daytime, WRKO is OK, WEEI comes in like 
gangbusters, WBZ is also OK

At night, WRKO disappeared into the weeds (which was a pain in the 
butt when the Celtics were first on the station and they were doing 
their historic run of championship seasons in the late 80s), while 
WEEI is still quite listenable.

I looked up WEEI's day and night strength up here in Nashua on the 
V-soft site. It claims 1.67 mV/m daytime, 1.47 mV/m nighttime.  If 
they're so close, why does WEEI disappear so badly at night?

As for using nonproportional fonts, can't you tell Outlook Distress 
to use Courier New?  That's a fine non-proportional font on the 
Windows side.
