That's about my observation about WJIB's night coverage as well.  Once 
you get the big hill (Belmont Hill / Wellington Hill) in your way as 
you head west on Route 2 beyond the big Mormon temple, the signal gets 
a bit choppy.  That would be about 4 or 5 miles from the tower.  Over 
the flatter terrain going south across Cambridge and the Charles, they 
probably get a bit farther into Allston and Brookline.  Despite the 
small area covered, it still reaches a lot of people.

Once in a while you get an "auroral night" when most skip interference 
is eliminated.  Then WJIB's 5 watts covers a bigger "box": that 
bordered by Norwood on the SW, Billerica on the NW, Beverly on the NE, 
and Cohasset on the SE.

A 3 Hz beat note (a.k.a. "subaudible heterodyne") is what Dan is 
observing between CHWO and WJIB.  Certainly that's within legal spec's 
but, yes, it's annoying when you have two similar-strength signals.  
But then, the clash of competing audio would be too.  CHWO and WJIB are 
both good stations for the nostalgic-music fan (on a band where this 
format has reached "few and far between" status).  It's too bad that 
they happen to be on the same channel.

In Arlington Heights, on my SRIII, rotated to maximize the signal 
of WJIB (which happens to about null WKOX, WAMG, and WBIX), WJIB is 
good on maybe 2/3 of nights (actually 2/3 of the time, because a night
that's good for receiving WJIB at, say, 8:00PM.can become pretty awful 
miidnight or vice versa). OTOH, the frequency difference between WJIB 
CHWO, which is usually about 3 Hz (or do I mean 1.5 Hz?--three signal 
per second), is pretty annoying. For me, the frequency difference seems 
have been chosen to maximize the sensation of vertigo.
