thought was a definitive audit of the available FM stations in my area.\u00a0 Then, just the other day I happened to tune down below 88.1 (FM Channel 201).\u00a0 At 87.7 MHz I came across some delightful Latin music in clear stereo and proceeded to park the tuning knob there for a listen.\u00a0 At first, I thought I might simply have some intermodulation from a strong local station, but the stereo signal was much too clear.\u00a0 So, I resorted to the internet to determine what was going on.\u00a0 Turns out, according to their website, I was listening to <i>DC 88.7FM<\/i> in Fairfax, Virginia \u2013 no call letters, just \u201cDC 88.7FM.\u201d<\/p>\n<p>Further investigation indicated that the station is officially WDCN-LD a low-power operator, but you won&#8217;t find it listed on the FCC FM Query site.\u00a0 That\u2019s because it is something of a legacy station, a carryover from analog TV days when the audio for Channel 6 was broadcast with the carrier centered on 87.75 MHz, within the range of most FM receivers.\u00a0 Having discovered this, I retuned the radio slightly to 87.75 MHz and found the signal strength peaked.\u00a0 Wikipedia describes the history of WDCN-LD at <a href=\"https:\/\/en.wikipedia.org\/wiki\/WDCN-LD\" target=\"_blank\" rel=\"noopener\">https:\/\/en.wikipedia.org\/wiki\/WDCN-LD<\/a>.<\/p>\n<p><a

100vw, 1200px\" \/><\/a><\/p>\n<p>Of further interest is the history of so-called \u201cChannel 6 FM radio stations.\u201d\u00a0 The evolution of present-day stations is long and involved.\u00a0 Over several years, the FCC formed committees, requested comments, held hearings, wrote reports, published proposals, rendered rulings, and ultimately granted waivers.\u00a0 For the full story, see <a href=\"https:\/\/en.wikipedia.org\/wiki\/Channel_6_radio_stations_in_the_United_States\" target=\"_blank\" rel=\"noopener\">https:\/\/en.wikipedia.org\/wiki\/Channel_6_radio_stations_in_the_United_States<\/a>.\u00a0 What resulted are legacy stations dating back to analog TV days which continue to operate <i>sans<\/i> video as <i>de facto<\/i> FM stations.\u00a0 For all practical purposes, we have a modest extension of the FM band.\u00a0 There are, in fact, 14 such stations currently spread across the lower 48 states.\u00a0 It is unlikely that the circumstances which created these stations will ever result in more stations being added.\u00a0 As of July 20, 2023, an FCC report and order restricted these stations to those already licensed and current licenses untransferable.<\/p>\n<p>Do you live near a Channel 6 FM radio station?<\/p>\n<p>Just to complete the picture, there is also officially an FM Channel 200 at 87.9 MHz, which was established in 1978, but to my knowledge is not used.\u00a0 Does anyone have any information on FM Channel 200?<\/p>\n<p>As an historical aside, the present-day FM band, 88 to 108 MHz, is located directly between analog TV Channels 6 and 7.\u00a0 In 1958, to foster FM use, Regency Electronics, Inc. marketed a converter, Model RC-103, in a handsome Bakelite case, which could be attached between the antenna (generally \u201crabbit ears\u201d) and the TV set.\u00a0 The converter contained a single transistor and was powered by three AA batteries.\u00a0 By tuning the TV to Channel 6, turning on the <i>TeleVerter<\/i> to FM, and rotating its dial, one effectively detuned the Channel 6 audio frequency upward, and could listen to the entire FM band.\u00a0 As this converter was manufactured prior to the advent of stereo broadcasting, the sound was in mono, and fidelity was limited to the audio quality of the TV.\u00a0 My dad bought one of these.\u00a0 It was connected to our Arvin 12\u201d, B\/W tabletop TV, and it served as our first FM radio for a few years.\u00a0 There were only a few stations at that time, mostly classical as I recall.\u00a0 Thus \u201cFM\u201d came to stand for \u201cfine music.\u201d<\/p>\n<div id=\"attachment_61041\" style=\"width: 553px\" class=\"wp-caption aligncenter\"><a
