Question: K25NK-D is a low-power television station in a city who as of 2015 has a metropolitan area population of what?
Context: WLPD-CD is a Class A low-power television station in Plano, Illinois, United States, broadcasting locally on channel 30 as an affiliate of Youtoo TV.  Founded June 30, 1988 as W30AL, the station is owned by Nelson Enterprises, Inc.  It holds a construction permit to build a low-power companion digital tv station on channel 18. WVFW-LD (channel 34) is a Spanish language low-power television station in Miami, Florida which is owned by Liberman Broadcasting and serves as an owned and operated station of the Estrella TV network.  Despite its owned status however, because it operates as a low-power station, Estrella TV also affiliates in Miami with the second subchannel of Sunbeam Television's Fox affiliate, WSVN (channel 7) to provide full-market coverage to South Florida. KNIK-LP is a low-power commercial television station in Anchorage, Alaska, broadcasting on VHF channel 6, taking advantage of that station's audio signal on 87.75 MHz FM.  The station is one of very few low-power television stations that operate predominantly as a radio station by way of the fact that many FM radio receivers can tune in a VHF channel 6 television audio carrier at 87.75 MHz.  This technique is made more potent due to a formerly unforeseen interpretation of deregulatory language in FCC low-power television station regulations: WDCN-LP is a low-power television station in the Washington, DC area, broadcasting locally on channel 6.  Currently broadcasting in Spanish, it was slated to adopt a dance music format under a lease agreement with Mega Media, a company which operates a similar station on channel 6 in New York City, WNYZ-LP.  Like WNYZ, WDCN was intended to be branded as "Pulse 87" and was slated to begin broadcasting in June 2009, but financial problems at Mega Media forced those cancellations.  87.75 MHz FM is the center frequency of channel 6's audio signal, which can be received on most FM radios and thus makes a music format viable.  WDCN LP is currently managed by Media One Communications, Inc. since August, 2009.  WDCN-LP is the flagship Spanish-language radio station for broadcasts of D.C. United soccer games.  It currently simulcasts on co-owned WOWZ-LP, another low-power channel 6 station, licensed to Salisbury, Maryland and serving the Ocean City-Salisbury area.

Five years later, the station was purchased by Block Communications of Toledo. W07BN-D (""TV-7"") is a locally owned Low-Power Digital television station licensed in Bruce, Mississippi.
