Low Power FM (LPFM) Channel Finder Results INCLUDES second-adjacent channel spacings Thu Oct 17 09:31:37 2013 INCLUDES intermediate frequency (I.F.) spacings Input options: Latitude, Longitude: 33° 26' 2", 88 29' 54" Google Map: 5.6 km radius (approximate 60 dBu service contour coverage) PASSED. LPFM spacing requirements are met to all stations and applications on one or more channels: Channels Available for LPFM LP100 Stations [Channels 201 to 300, corresponding to 88.1 to 107.9 MHz] Channel 238 ---- 95.5 MHz Channel 243 ---- 96.5 MHz Channel 244 ---- 96.7 MHz Channel 246 ---- 97.1 MHz Channel 247 ---- 97.3 MHz Channel 271 ---- 102.1 MHz Channel 272 ---- 102.3 MHz Channel 273 ---- 102.5 MHz Channel 279 ---- 103.7 MHz Channel 294 ---- 106.7 MHz This analysis does not determine whether an LPFM station at this location and channel might receive interference within its 60 dBu LPFM service contour from FM broadcast stations already operating or authorized in the band from fully spaced locations. LPFM stations must accept all such interference. Because the FM database constantly changes, there is no guarantee that channels represented as "available" will be technically acceptable at the time of application filing. Available Channels Interference Analysis This section considers the acceptable LPFM-use channels listed above, and determines which of these channels will be less likely to suffer interference from existing or authorized stations. This analysis only considers spacing, and assumes that the interfering stations are operating with the reference facilities for the FM station's class. While helpful, the results shown below should not take the place of a thorough analysis of all options by a broadcast consulting engineer. If interference is possible, the following table will contain: o Call Sign of the interfering station o Channel of that station o Channel relationships: Same channel OR First-adjacent channel OR Second-adjacent channel o Actual separation (in km) o Minimum Separation for no interference within the 60 dBu contour (based on reference facilities and flat terrain) Channel 238 Channel 271 Channel 243 WMJJ 243 Same channel (cochannel) 150.5 km actual 193.0 km for no interference Channel 244 WCKK 244 Same channel (cochannel) 103.5 km actual 143.0 km for no interference Channel 246 WOKK 246 Same channel (cochannel) 124.2 km actual 178.0 km for no interference Channel 247 WWMS 248 First-adjacent channel 101.7 km actual 111.0 km for no interference Channel 272 NEW 272 Same channel (cochannel) 84.1 km actual 92.0 km for no interference NEW 272 Same channel (cochannel) 89.3 km actual 92.0 km for no interference Channel 273 WDXB 273 Same channel (cochannel) 150.5 km actual 178.0 km for no interference Channel 279 WQEN 279 Same channel (cochannel) 150.5 km actual 178.0 km for no interference Channel 294 WWZD-FM 294 Same channel (cochannel) 122.4 km actual 143.0 km for no interference A simple test for potential interference is to tune a radio to the channel or frequency under consideration, while at the proposed transmitter site. If a station can be heard, you should expect that coverage from an LPFM station may be diminished. Interference to the LPFM station could occur at some future date should the listed FM station increase its facilities to the maximums permitted for the station's class. AM Stations Within 3.2 km Use this button to check for AM stations within 3.2 km [2 miles] of the coordinates specified above. If a nondirectional AM station appears within 0.8 km of these coordinates, or a directional AM station appears within 3.2 km, the LPFM applicant is responsible for measures to protect the AM station from changes in its operation caused by the LPFM antenna-supporting tower structure. See 47 CFR 73.1692. LPFM applicants should be aware that remediation may be costly if it becomes necessary to mitigate the impact on the AM station. 'No records found' indicates that the coordinates are not within 3.2 km of an AM station. Airports Within 8 km (5 Miles) The tool below allows you to check for airports within 8 km of the proposed station's coordinates. If you get a FAIL message, or if your proposed tower or supporting structure will be greater than 200 feet (61 meters) at ANY location, then you MUST obtain clearance from the FAA using FAA Form 7460-1, and the FAA-approved structure must be registered with the FCC via the Antenna Structure Registration (ASR) system. The FAA's Form 7460-1 and FCC antenna structure regioistration both require coordinates in the NAD83 coordinate system. To convert from NAD27 coordinates (used for broadcast station analyses) to NAD83 coordinates, you may use the National Geodetic Survey's conversion program at: http://www.ngs.noaa.gov/cgi-bin/nadcon.prl. Once you have obtained the converted coordinates, copy them down and enter them into the FCC's Wireless Telecommunications Bureau's TOWAIR Query If the proposed structure does not pass the TOWAIR test, you will need to request FAA clearance and register the antenna structure with the FCC once clearance is obtained from the FAA.
