F(50,50), F(50,10) FM,TV Propagation Curves Graphs
F(50,90) Digital TV Curves Graphs
FM to TV Channel 6 Interference Ratios Graphs
In response to numerous requests, we provide below new graphical implementations of the
FM and TV propagation curves graphs contained in Sections 73.333 and 73.699 of the
FCC's rules. F(50,90) digital television service graphs are also provided
although these are not in the FCC's rules. Lastly, we provide the Figure 1 and 2 graphs
from Section 73.599, containing the interference ratio curves from
FM noncommercial educational stations to TV Channel 6 stations.
These graphs have been generated in three formats, PDF, PostScript, and as PNG images.
PDF graphs should be retrieved where the image must be resized from the default
11 inch by 17 inch graph size, for example when printing to standard 8½" by 11" paper. PDF files
are also the quickest to download. PNG files should be used where the graph is to
be viewed on the Internet, in the same manner (within an <IMG > tag) as .jpg or .gif
images. The PostScript version is made available for those users with
PostScript-capable printers, and is best printed at the 11" x 17" size. The
PostScript version may be viewed using GhostScript and GhostView, or other
PostScript viewer. Each graph is also provided the three options for the
graphed curves color (black, red, and blue).
The Audio Division maintains an on-line F(50,50), F(50,10), and F(50,90) propagation
curves calculator at http://www.fcc.gov/mb/audio/bickel/curves.html.
