Technical Narrative This Technical Narrative and attached exhibits were prepared on behalf of North Georgia Radio
Group, L.P. (“NGRG”), licensee of FM Translator W252CR, Facility ID No. 139684, Dalton,
Georgia. NGRG herein is filing a minor modification application to increase the antenna height
above ground level. No other changes are being proposed.
The proposed W252CR facility would operate on Channel 252D (98.3 MHz) with 250 watts
directional with the transmit antenna located at 67 meters height above ground level and 99.6
meters HAAT. An exhibit demonstrates that the proposed W252CR FCC F(50,50) 60 dBu
contour is contained within a 25 mile radius of primary station WDAL(AM). Therefore, it is
believed that this application is in compliance with Section 74.1201(g) of the Commission’s
rules.
A channel study is included as an Exhibit. It assumes a Class A 6 kW facility operating on
channel 252 and is provided to FCC staff as a convenience to help identify potential contour
overlap issues. Exhibits are provided demonstrating Section 74.1204 contour protection to Co-
channel full power FM stations WKEA-FM CH252C3, Scottsboro, Al and WMTY-FM
CH252A, Sweetwater, TN, third adjacent full power FM stations WNGH-FM, CH255C3,
Chatsworth, GA and WSB-FM CH253C0, Atlanta, GA, first adjacent full power FM station
WLND CH251A, Signal Mountain, TN, first adjacent FM translator W253BO CH 253D,
Collegedale, GA and third adjacent FM translator W250BK, Chatsworth, GA.
Because there is no change in the transmit location there is no exhibit demonstrating compliance
with FCC Section 74.1233(a) “Common Overlap”. A study has been undertaken to show the
proposed facility is in compliance with the Commission’s radio frequency emission limits and is

Human Exposure to Radiofrequency Electromagnetic Field &
Section 106 Compliance (Environmental)
A study has been made to determine whether this proposal is in compliance with 47 C.F.R. 1.1307 of the Commission’s rules and with OET Bulletin #65, dated August 1997, regarding human exposure to radio frequency radiation in the vicinity of broadcast towers. North Georgia Radio Group, L.P. (“NGRG”), licensee of FM Translator W252CR, Facility ID No. 139684, Dalton, Georgia. W252CR will simulcast co-owned AM primary station WDAL, 1430 kHz, Facility ID No. 54518, licensed to Dalton, GA. The W252CR transmit location is a tower 71.3 meters in overall height and is located at 34° 49' 42" N ~ 84° 53' 41" W (NAD 83). The tower is registered with the Antenna Registration Structure "ASR" number 1032618. The proposed antenna is a Nicom Model BKG77 two bay circular polarized directional antenna with a center of radiation of 67 meters AGL. W252CR will operate on Channel 252D, 98.3 MHz, with 250 watts ERP directional at 99.6 meters HAAT. The use of existing transmitting locations has been characterized as being environmentally preferable by the Commission, according to Note 1 of § 1.1306 of the FCC Rules. Because the proposed new facility proposes to operate from an existing tower and no modifications are being made to the tower, it is believed to be exempt from a Section 106 review by the SHPO/THPO.
The proposed operation was evaluated for human exposure to RF energy using the procedures outlined in the Commission’s OET Bulletin Number 65. The Nicom antenna is included in the recently revised OET FM Model Program under Type 2, Opposed “V” dipole. Using the Type 2 antenna selection, the maximum calculated signal density near the tower at two meters above ground level attributable to the proposed facility is 1.088 µW/cm at 66.6 meters, which is 0.544 percent of the general population/uncontrolled maximum permitted exposure limit. This is well below the five percent threshold limit described in 1.1307(b) regarding sites with multiple emitters, which excludes applicant from responsibility for taking any corrective action in areas where the proposal’s contribution is less than five percent. The applicant will see that signs are posted in the vicinity of the tower, warning of potential radio frequency hazards at the site. The applicant will cooperate with other users of the tower to reduce power of the facility, or discontinue operation, as necessary to limit human exposure to levels less than specified by the Federal Communications Commission should anyone be required to climb the tower for maintenance or inspection.
