Digital Television Channel Allotment
This page contains data and software that may be used to perform DTV related analysis. The software on this page is provided "as is."
The compressed files "terrain.zip" and "population.zip"
contain data needed to run the tv processor program. The terrain
and population data are the same as previously available.

| The Fortran computer code P27tvIX can be used to predict the percentage of interference that Part 27 base station(s) would cause to existing TV service. This program is a modification of the FLR Fortran program which is used to evaluate allocation options for DTV stations. The modifications include: capability to enter data on Part 27 base stations ( same parameters required as for TV stations ), employing "root sum of squares" addition when more than one Part 27 base station is involved, and use of D/U ratios from CFR 47, Part 27 as the interference metric. The rational behind these modifications is described in WT Docket number 05-7. |

This computer code can be used to predict the percentage of interference that would be caused by an application for a new or modified TV station to existing TV stations operating with facilities as set forth on Appendix B of the Seventh Report and Order in MB Docket No. 87-268. Also, the population and coverage area for proposed modifications to existing stations can be computed and compared to the population and coverage for such stations operating at facilities as specified in Appendix B. This program uses two publicly available software packages for contours plotting and formats conversion: NCAR Graphics package from the National Center for Atmospheric Research for contour plotting, and GhostScript for converting from PostScript to PDF.
