Tower hunter (cont'd)

[Dan Strassberg]

The info comes from Bob Carpenter's AMSTNS, a program you can download for
free. Just Google "AMSTNS download" (without the quotation marks). AMSTNS is
a DOS application that runs fine in a DOS window under Windows. AMSTNS in
turn gets the info from the FCC's CDBS database. CDBS data is available at
the AM Query page at www.fcc.gov, but I find AM Query much less convenient
to use than AMSTNS.
