Question: WLYN is a station is licensed to the largest city in what county?
Context: WSYY-FM (94.9 FM) is a radio station broadcasting for approximately 18¼ hours per day, 7 days a week (from 4:55AM through 11:10PM ET) under the slogan, ""Radio With An Attitude"".  Playing a mix of oldies/classic hits, adult contemporary, rock music, and some country crossovers, the station broadcasts an Adult Hits/Full-Service format for approximately 16 hours per day, from 6:00AM through 10:00PM ET (reserving the first and, also, the final hour of their broadcast day to "When Radio Was").  "The Mountain 94.9" carries local high school sports in season.  "The Mountain 94.9" had also carried the complete schedule of Red Sox Baseball (from 1997 through 2015, prior to becoming a Former Affiliate in 2016, which was when Millinocket's affiliation with the Red Sox Baseball would ultimately be transferred over to co-owned WSYY-AM, thus concluding the frequent interruptions to the music on "The Mountain 94.9" during Baseball season).  The station currently features programming from CBS Radio and carries CBS Radio News at the top of every hour (and has been an affiliate of that network for many decades).  Licensed to Millinocket, Maine, United States, the station's broadcast signal serves the Central Penobscot County, Eastern Piscataquis County, and Southern Aroostook County Maine areas, and the station is licensed to serve the town of Millinocket, Maine, the very town where its studios/offices and tower site are located.  The station is currently owned by Katahdin Communications, Inc.  WSYY-FM originally went on the air in 1978 on 97.7 FM as WKTR, upgrading to its current facilities in 1984 on 94.9.  Prior to their "The Mountain 94.9" branding, WSYY-FM used to be referred to as "North Country 95", airing a full-time Country Music format.  The current format, branding, and slogan was probably adopted around March 1, 2004, when Katahdin Communications, Inc. assumed control of WSYY-FM & WSYY-AM from Katahdin Timberlands, LLC (as a result of the radio station facing increasing land disputes), initially as a short term lease agreement but the transfer of ownership ultimately became permanent.  Those same land disputes would eventually lead to a loss of WSYY-FM's 23,500 watt transmitter location (featuring an antenna HAAT of 211 meters); as a result, WSYY-FM may have been operating under a Special Temporary Authority License (a 12,000 watt facility with an antenna HAAT of 68 meters via Hammond Ridge on Lake Road, about two miles from Millinocket Municipal Airport), ever since as long ago as late 2007, pending a planned permanent move to a 22,000 watt facility with an antenna HAAT of 198.4 meters (from just off Nicatou Road in Medway, well east of WSYY-FM's old or current transmitter tower location).  On November 23th, 2016, the CP for this proposed move was modified to a 45,000 watt facility with an antenna HAAT of 146.7 meters, the first time this proposed move has ever received official approval from the FCC.  WSYY-FM is one of the two Maine affiliates—apart from WLOB—of When Radio Was (7 days a week from 5:00AM through 6:00AM ET and also from 10:00PM through 11:00PM ET), is one of the two Maine affiliates (WWMJ) of The Acoustic Storm (Saturdays from 9:00AM through 12:00PM ET), is Maine's only affiliate of the Crook & Chase syndicated Country Music countdown programming (Sunday afternoons from 2:00PM through 6:00PM ET), and is an affiliate of the Blues Deluxe radio show.  WSYY-FM/WSYY-AM are unusual in that while these stations are authorized to broadcast 24 hours a day, the stations both have sign-offs every day (WSYY-AM signing off at sun-down, broadcasting only on Weekends (but not between Monday-through-Friday) and WSYY-FM broadcasting for approximately 18¼ hours per day, 7 days a week, WSYY-FM's broadcast day concluding with the 11:00PM ET Top-of-the-Hour CBS Radio newscast and then a Nightly Sign-Off Announcement and then an instrumentation of the American national anthem, followed by Dead Air amidst a Transmitter Power-Down, not Signing Back Onto The Air until 4:55AM ET).  In Old Town and also Bangor (and continuing southward and/or southwestward), the station has strong FM co-channel interference with Portland-market WHOM (which transmits from atop Mount Washington in New Hampshire, the tallest peak in the Northeast and had for a long time claimed on its website that it has the largest coverage area of any FM station in the United States, its signal spanning five states: NH, ME, VT, MA, NY and also parts of Southern Quebec Province, Canada), this matter being especially problematic before dawn or after dusk.  In favorable atmospheric conditions, a very weak signal of WHOM can be DX-ed in Millinocket during overnight hours (when WSYY-FM is off-the-air). Waterbury (nicknamed "The Brass City") ( ) is a city in the U.S. state of Connecticut on the Naugatuck River, 33 miles (45 minutes) southwest of Hartford and 77 miles (90 minutes) northeast of New York City.

Founded around 1838 after the merging of two communities, Old Anvil and New York Station, the latter a station on a stagecoach line.  The rail came through in the 1850s and later, the "New" was dropped from York Station in 1861.  With the discovery that another community in Alabama bore that name, the "Station" was dropped and York was formally incorporated on April 6, 1881.  At the 2010 census the population was 2,538, down from 2,854.  From 1920-1980, it was the largest town in the county.

Licensed to Jefferson City, Missouri, United States, the station serves the Columbia, Missouri area.  The station is currently owned by Cumulus Media and features programing from ABC Radio and Westwood One.  KLIK also operates a local news operation with sister station KFRU (1400 AM in Columbia, Missouri).  From 1954 until September 8, 1999, KLIK was located at 950 AM, transmitting with a daytime power of 5000 watts and a nighttime power of 500 watts (directional) from a four tower array about 3.2 miles south of Jefferson City.  Early owners of KLIK broadcast a varied format of news and talk programs including music programs of middle of the road, top 40, adult contemporary and country music as 95 KLIK.  For many years, KLIK and KJFF as the two largest regional radio stations (the most powerful AM and FM station in the region) dominated radio listenership in cumulative market share in the Columbia-Jeff City Market of Central Missouri.  In the 1970s and early 1980s KLIK was known as the Live 95 as its broadcasts were all programmed by live deejays, talk hosts and newscasters rather than by a satellite or automation system.  KLIK once operated with an FM sister station in the 1970s and 1980s known was KJFF 106.9 FM a 100,000 watt semi-automated easy listening music station with a large regional coverage signal.  In the early 1980s KLIK and KJFF-FM together were sold by the local Jefferson City operators to a regional group broadcaster, and newspaper publisher, Brill Media.  In about 1982, KJFF-FM 106.9 FM became an adult contemporary music station, initially with a satellite delivered music format, and easy listening music was phased out along with the KJFF call letters which were replaced by the new FM call signs of KTXY.  KLIK 950 AM transitioned over from AC/Contemporary music at about the same time to a 24-hour-a-day live country/western format known as 95 Country.  KLIK carried a variety of programming and a mostly country music format until the late 1990s. Rome is the largest city in and the county seat of Floyd County, Georgia, United States.

Situated on the Atlantic Ocean, approximately 10 mi north of downtown Boston, Lynn is part of Greater Boston's urban inner core.  An early colonial settlement and industrial center, Lynn was long colloquially referred to as the "City of Sin," owing to its historic reputation for crime and vice.  Today, however, the city is known for its large international population, historic architecture, downtown cultural district, loft-style apartments, and public parks and open spaces, which include the oceanfront Lynn Shore Reservation; the 2,200-acre, Frederick Law Olmsted-designed Lynn Woods Reservation; and the High Rock Tower Reservation.  The city also is home to the southernmost portion of the Essex Coastal Scenic Byway, Lynn Heritage State Park, and the National Register-listed Diamond Historic District. WSTU (1450 AM) is a radio station broadcasting a talk radio format.  Licensed to Stuart, Florida, United States, the station is currently owned by Treasure Coast Broadcasters, Inc.  WSTU went on the air in December 1954.  Les Combs was the original owner.  In 1969 the station was sold to Harvey L Glascock, whose family owned the station until 1997 when it was sold to American Radio.  After a brief ownership by a Broward County businessman, it was sold to Barry Grant Marsh and David Pomerance.  Marsh had been Operations Manager of WSTU for many years under the Glasscock family.  The station was purchased by Treasure Coast Broadcasters in 2001.  When WSTU went on the air, Stuart went from the biggest city on Florida's east coast without its own radio station to the smallest city on Florida's east coast with its own radio station.  WSTU had a strong local news commitment from the very first, and continues that to this day under News Director Tom Teter, who has been with the station since 1980.  Teter has won many awards for news excellence from UPI and AP including Best Newscast in Florida and Best Spot News Reporting.  From the earliest days the Martin County community viewed the station as more of a public utility than a privately owned radio station.  WSTU was also one of the first radio stations in Florida to broadcast high school sports on a regular basis and continues to broadcast high school football, basketball and baseball.  Hamp Elliot did the play-by-play for many years followed by Teter who handled the play-by-play for more than 20 years.  Rick McGuire now does much of the play-by-play.
