Bickel, Audio Services Division, Mass Media Bureau, Federal Communications Commission (FCC) VERY VERY EXTENSIVE. For more information see Audio Services Division: AM & FM Radio Broadcasting or the Federal Communications Commission (FCC) Some examples from over "10" Calculators include FM Channel to Frequency Field Strength: dBu to/from mV/m Transmission Line Efficiency Electrical Degrees to/from Meters ONLINE BROADCAST ENGINEERING RELATED CALCULATORS - A.D. Kass VERY EXTENSIVE. For more information see Allen's Engineering Home Page Some examples from over "10" Calculators include AM Common Point/Antenna Current Calculator AM Transmiter Harmonics Calculator Standing Wave Ratio Calculator RPU/STL Frequency Tolerance Calculator COORDINATES FOR CALCULATORS SEE NAVIGATION CALCULATORS: DISTANCE & LOCATION AN EXAMPLE DISTANCE AND AZIMUTHS BETWEEN 2 SETS OF COORDINATES CALCULATOR - D. Bickel, Audio Services Division, Mass Media Bureau, Federal Communications Commission (FCC) VERY EXTENSIVE. "This program will calculate the distance and azimuth (referenced to True North) between two sets of coordinates on the earth. " Choose Method of Calculating Distance: "Distance per Sections 73.208 (FM) and 73.611 (TV)" or 'Distance per the Great Circle Method (AM)". For more information see Radio Tools or the Audio Services Division CUMULATIVE LEAKAGE INDEX CUMULATIVE LEAKAGE INDEX (CLI) CALCULATOR - C.E. Harrington, Engineering and Technical Services Division, Cable Services Bureau, Federal Communications Commission (FCC) "This special calculator has been designed to calculate the Cumulative Leakage Index(CLI)." For more information see Engineering Division; Media Bureau or the Federal Communications Commission (FCC) DBN/DBW CONVERSION DBM/DBW CALCULATOR (JAVA APPLET) - Besser Associates "...Using dB notation simplifies power calculations in communications systems. For example, if the measured power at the input of an amplifier is 5dBm and the gain of the amplifier is 20dB, then the measured..." For more information see Applets or Besser Associates FCC INTERACTIVE DATABASES FCC INTERACTIVE DATABASES - Federal Communications Commission (FCC) Major FCC Interactive Databases include Tools & Databases FCC ID Equipment Authorization Database AMQ AM Radio Database FMQ FM Radio Database Video Division Databases TVQ TV Database FM AND NTSC TV PROPAGATION CURVES FM AND NTSC TV PROPAGATION CURVES CALCULATIONS - D. Bickel, Audio Services Division, Mass Media Bureau, Federal Communications Commission (FCC) VERY VERY EXTENSIVE. "This program uses the FM or NTSC (analog) television propagation curves to compute distances to contours or a field strength at a given distance. (Digital television uses a different set of curves and is not included here.)" For more information see Radio Tools or the Audio Services Division FM BROADCAST CHANNEL TO FM FREQUENCY CONVERSIONS ETC. FM BROADCAST CHANNEL TO FM FREQUENCY CONVERSIONS & FM BROADCAST FREQUENCY TO FM CHANNEL NUMBER - D. Bickel, Audio Services Division, Mass Media Bureau, Federal Communications Commission (FCC) VERY EXTENSIVE. For more information see Radio Tools or the Audio Services Division SUNRISE/SUNSET CALCULATOR FOR AM STATIONS SUNRISE/SUNSET CALCULATOR FOR AM STATIONS IN THE U.S. - D. Bickel, Audio Services Division, Mass Media Bureau, Federal Communications Commission (FCC) "These values are important to those AM stations who must reduce power, cease operations, or change to directional operation during the nighttime hours, as well as the stations protected by the changed operation."
