WSTU: 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.

The station was originally operated by Northwood businessman, Marlin Hanson as an oldies radio station with an effective radiated power of 3,000 watts, then 6,000 watts.  Hanson built the station because he bought the tower from the local cable company after they abandoned it and decided a radio station would be a good use for the empty tower.  It was sold to Dave Nolander who also owned KATE radio in Albert Lea, MN.  It was operated as an oldies station featuring music of the 50's and 60's from a studio located in Northwood and satellite programming during the evening hours.  The station was sold to Three Eagles Communications and the power increased to 25,000 watts.

WSYY-FM: 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).

WGMF: WGMF is an AM radio station licensed to the city of Tunkhannock, Pennsylvania and is part of the Scranton/Wilkes-Barre radio market.  It broadcasts on a frequency of 1460 kHz with 5,000 watts daytime, and 1,000 watts nighttime power with a directional signal.  WZMF is an AM radio station licensed to the city of Nanticoke, Pennsylvania and is part of the Scranton/Wilkes-Barre radio market.  It broadcasts on a frequency of 730 kHz with 1,000 Watts daytime, and 12 Watts nighttime power.  The WGMF-WZMF studio is located on Wilmar Drive in Tunkhannock, Pennsylvania with phone number 570-836-4200.  WGMF formerly simulcast the adult contemporary format aired by its sister station, WCOZ, now KZ104, in neighboring Sullivan County, but now airs a classic hits format.  The station identifies itself primarily by its translators at 104.3 and 104.5 MHz, hence the name "Gem 104".

WHAD: WHAD (90.7 FM) is a non-commercial radio station licensed to the western Waukesha County community of Delafield, Wisconsin and serving the Milwaukee metropolitan area, transmitting from south of Delafield.  Part of Wisconsin Public Radio (WPR), it airs WPR's "Ideas Network", consisting of news and talk programming.  Like the Milwaukee area's other NPR station, WUWM (licensed to Milwaukee proper), the station airs BBC World Service in the overnight hours.  WHAD maintains a local news staff and cut-ins outside of the main WPR network, and the station's facilities, located on the seventh floor of 310 W. Wisconsin Avenue in Milwaukee (by coincidence, also hosting the studios of commercial sports radio station WAUK), originate some programming for the network, including Kathleen Dunn's afternoon program until her retirement in the summer of 2017.  WHAD has its own 414 studio line for Milwaukee callers to call into locally originated programs.  Because of the lack of a sister station providing WPR's News and Classical Network to Milwaukee, WHAD provides the HD2 Classical Network via HD Radio to the market via their HD2 subchannel, which only differs from the News and Classical Network in having a full-classical format overlaying NPR and APM news programming exclusive to WUWM in the market; it became the market's only classical music station over the air in 2007 after WFMR abandoned the format commercially.

WTMJ (AM): WTMJ is an AM radio station in Milwaukee, Wisconsin broadcasting at 620 kHz and at 94.5 FM HD-2.  The station was the flagship radio station of the Journal Broadcast Group until April 2015, when it came under its current ownership of the E.W. Scripps Company.  JBG also owned the Milwaukee Journal Sentinel, WTMJ-TV and sister radio station WKTI, along with other media assets across the U.S. (WTMJ remains owned with WTMJ-TV and WKTI, with the "Journal Sentinel" owned by the Journal Media Group spin-off until their April 2016 merger with Gannett).  WTMJ maintains studio facilities located on Capitol Drive in Milwaukee (this Art Deco facility is known as "Radio City" in tribute to the New York complex of the same name), and its transmitter is located in Union Grove.
