Jefferson Standard merged with Pilot Life in 1968 (although it had owned controlling interest since 1945) and became Jefferson-Pilot Corporation. Shortly before the television station went on the air, its call letters were modified from WBT-TV to WBTV. Jefferson Standard had purchased WBT from CBS in 1947. At the time, the Jefferson Standard Life Insurance Company also had a 16.5% interest in the Greensboro News Company, licensee of WFMY-TV, which signed on from Greensboro two months after WBTV. WBTV was originally owned by the Greensboro-based Jefferson Standard Life Insurance Company, owners of WBT (1110 AM), the city's oldest radio station and the first fully licensed station in the South. Veteran Charlotte broadcaster Jim Patterson was the first person seen on the station, and remained employed there until his death in 1986. When it debuted, WBTV was the 13th television station in the United States and the first in the Carolinas it is the oldest television station located between Richmond and Atlanta. The station first signed on the air on July 15, 1949. In addition, WBTV's studios continue to house the operations of its former sister radio stations currently owned by Urban One: WBT-AM/ FM and WLNK, as well as WFNZ, which was previously owned by CBS Radio prior to its acquisition by Beasley Broadcast Group in 2014, followed by Entercom (now known as Audacy) in late 2017 and then Urban One in 2020 under a local marketing agreement. The station's studios are located off Morehead Street, just west of Uptown Charlotte, and its transmitter is located in north-central Gaston County. Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall.WBTV (channel 3) is a television station in Charlotte, North Carolina, United States, affiliated with CBS and owned by Gray Television. Hail is a good reflector of energy and will return very high dBZ values. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate. Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Notice the color on each scale remains the same in both operational modes, only the values change. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). "Reflectivity" is the amount of transmitted power returned to the radar receiver. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
