Re: WCAP/WTRY (was: WSRO/let's be civil.../community radio...)

As far as I know, WTRY (AM) has been required to use the same strength and
pattern from the same towers forever. (Or at least for many years.) Directional
nights 5kw from 3 towers, 5kw non-directional days. My recollection is that the
night pattern is weaker to the east, though I'm not 100% sure of that. The
towers are in the Town of Niskayuna, Schenectady County, NY -- barely inside the
eastern town line, just off Route 7.

At least to a local listener, there's been no recent change in night strength
audible to the naked ear, including in the eastern end of the market area,
though I know that can be quite deceiving. :)
