100.7 WMMS heard in Cincinnati - Tuesday, August 14, 2007

It's called "troposcatter" and pretty common in the summer, especially when there's a temperature inversion. The signals are reflected by the troposphere and generally will come back to earth 100-250 miles away fromt he transmitter. Here in Cleveland, we've been getting the Detroit FM's pretty regularly.
 
Things I got in between Steubenville in Eastern Oh and Dayton.
When in the Zanesville area, I pickedup Q99 out of Roanoke, VA. Yikes!
The best one happened when I got past Columbus when I picked up KissFM out of Lexington, KY and then WNOX out of Knocksville TN!
 
Rob... Didn't mean to insult your intellegence, bro. From your post you sounded a bit surprised. In addition to tropo-scatter or tropo-ducting as it's sometimes called, FM signals also sometimes get transported by sporadic-e. This is a true skywave, where the signal bounces off the e-layer of the ionosphere, but is somewhat rare in FM and TV frequencies, whereas at lower frequencies this phenomenon occurs daily (or in the case of AM, nightly). I'd be interested to hear from some of you out there if you've experienced this phenomenon where FM signals may be heard 500 to over 1000 miles from the tower site. Here in Cleveland, I've logged reception from Moultrie, Ga. (900 mi.), Rapid City, SD (1200 mi.), and Gillette, Wy. (1350 mi.).
 
Clevland is the farthest i got except of a station out of Indiana that was like 4hr 32 min away from me. I would get more if i could have my antenna outside but my condo development wont let me put my outdoor antena on the roof. i got it as high as i could get it in my room where my stereo is.
 
I wish we could get WMMS here in Pittsburgh, unfortunately we have a Star 100.7 that would wipe out any hopes of picking them up even with a tropo or sporadic-e opening. Being a ham operator I know what these occurrences are, but never really attributed them to FM broadcast bands, I guess because the signals don't bounce like on AM radio. You guys have posted some very interesting reports for FM DX. Being this is the low point of the sunspot cycle I didn't really expect to hear much about tropo or E openings.
