All other channels are Regional channels. If the expanded band is regional (these are local, I thought...) then there is 52. Expanded band stations are Class B, for now, although I wouldn't put it past some country to try to notify one of theirs as a Class A. Again, the 60 clears are total for North & South America, or am I mistaken? Total for this ITU region. There is at least one Class I station (either Class I-A or Class I-B) on every clear channel, and all such clears are clearly identified in the NARBA and Rio treaties as to power and antenna efficiency (although for some Mexicans, the antenna efficiency may be bogus). Where would this listing be located on the web? The FCC AM site. List all stations on any clear channel (by specifying no call letters and restricting the frequency range to any one specific clear channel) and observe the class letter. "A" is Class A, "B" is Class B, etcetera. On a clear channel, you should find only As, Bs and Ds. Central American stations will show up, too, and some of these are notified as described, but many are not. My assumption is if the FCC database has no class letter, then the United States has not "accepted" the station's notification, or the class is indeterminate. It is common for any change to be submitted to Canada and Mexico for acceptance, particularly in border areas, and vice versa. This is one reason why almost all of L.A.'s FM's are operating way above Part 73 power ... because they started out that way, and when it came time to formalize those existing operations, Mexico was requested to accept those operations, which Mexico did, thereby "grandfathering" those stations with very high (most) or even super power (KPFK). |
