Wow, this is an awful article! It should at least have a reference to why 608-614 MHz is essential for radio astronomy (I have read about this several times, but all were 20 or more years ago). It is not very well written, either. If I knew more about the content, I would fix it.
Also, references to "Channel 37" that refer to a different band of frequencies are irrelevant, and should be relegated to a footnote. The current article confuses readers into wondering about interference from Trinidad with radio astronomy, and then at the end says, Well, there's really no interference because the frequencies are different. This is just bad writing, probably an artifact of the article being edited by several people, some of whom did not understand the problem.
I'm confused. I just went to channel 37 on my TV and it was Spike TV. But this article says no station uses channel 37.

- I could be mistaken, but channel 37 is not allowed to be used for over-the-air broadcasts. Cable TV is not likely regulated in the same way, since it is not over the air....teddy (talk) 18:24, 22 November 2007 (UTC)
- Cable television converters do not use the same frequencies; their channels 14-22 occupy a midband (120-174 MHz) position directly below channel 7 while 23+ represent a superband (directly after VHF channel 13) position starting at 214MHz. The real OTA UHF channel 14 starts at 470MHz and the other UHF stations above this frequency, contiguously, on 6MHz spacings. Only channels 2-13 are at the same frequency as cable channels and as the similarly-numbered over-the-air counterparts. --18.104.22.168 (talk) 12:09, 18 May 2008 (UTC)
Ultimately a table needs to be created that shows (using 500kHz slices) the global TV allocations around 605-615MHz to show how the North American (System-M) channel 37 could be interfered with. The TV Audio subcarriers (including NICAM) are becoming less important as time goes by due to the conversion to HDTV. Primary emphasis should be on the DTV carrier frequency, as it is essentally identical to the analog video carrier frequency. —Preceding unsigned comment added by Beland (talk • contribs) 17:38, 10 January 2008 (UTC)
