Thanks Len. I've been there and done that many times but not recently. So I just went again and checked it out as a result of your advise. Very interesting result, too.
Despite the fact that WNYW 5.1 is broadcasting at considerably higher power than WWOR 9.1 (MY9), it's considerably further down on the list. It comes in at -9.2 for me whereas MY9 is 8 places above it at -4.1
For comparison's sake, WNET 13.1 is 8 places above MY9 at +3.2. WLVT 39.1 is actually 2 places below WNET at +2.5, and that's a very strong station for me, even when I'm pointed toward Philly and not really toward Bethlehem. WNET is not a strong station for me at all. I'm on the edge of good reception for them and really can't get them without rather serious issues. It's watchable, but just barely.
Now, I know that WNYW's higher power might not mean much because they are broadcasting at a higher RF than MY9, and ya have to take both the RF and power into consideration (however that works), but TV Fool does reflect that I should be getting MY9 somewhat better -- maybe even considerably better -- than WNYW 5.1
Which is indeed the case.
So TV Fool does seem to confirm what I'm seeing at my place. I'm on the edge for MY9 but thankfully get it well enough, and I'm also on the bad side of the edge for WNYW 5.1, and thus can't quite pull it in.
For whatever reason.
As I'm writing this, I now see George Molnar's post which seems to have a pretty good explanation as to why I'm seeing what I'm seeing.
