I'm only about 9 blocks from the ESB, mlr, and have the reverse reception--only CBS (UHF 56)) reliably and Fox/UP (44.1, 44.2) intermittently. The erratic remapping of Fox to 5.1 and UPN apparently not remapping correctly is the topic of a recent thread--at least something similar to that.
CBS, according to a post a while back, is transmitting at much higher power levels than Fox/UPN. You may be able to pick up CBS from a reflection, which can come in at almost any angle. While building walls are generally well shielded, sometimes moving antennas to different areas of the room can make a big difference in reception. I'm using the book-size Silver Sensor antenna because it has narrow reception pattern, rejecting numerous multipath (reflecting) signals that often throw off H/DTV reception in Manhattan. It's not necessarily better than different models in other NYC areas.
If you happen to have Time Warner cable, you could pick up WCBS-DT with a direct cable connection to your DTC-100, using an antenna, not cable, terminal and tuning to channel 46 (not 56). This is TWC's 8-VSB version of CBS (just like over the air, but a different channel). Also, if you call TWC's special HDTV number (212 598 7363, or perhaps 598 7312 these days) you can get on the list for a HDTV cable converter. These 2000HDs (currently) give you HDTV HBO, CBS, Showtime, and NBC on cable channels 701-704. Rumors suggest Fox (EDTV or 480p only), ABC, and PBS may soon be added at 705, 707, and 713.
Don't have a DBS viewing angle at all (southeast), but if you do (see DBS forum) there are several good HDTV sources via satellite, including HDNet (DirecTV), with programming not available on other sources. Also, there are apparently techniques for getting network HDTV signals from Canadian DBS sources, although it may require giving a false address. There has been some discussion of this method here
, which you could uncover with a search, and it may have been outlined on AVS forums, too. -- John
