Reading the papers and watching the news this weekend, one would think that analog television is a relic of the past – something that we can all soon look back at fondly as a quaint childhood memory, never to be seen again.  Yet all the reports fail to mention that for populations that watch their over-the-air television from TV translators or Low Power TV stations, analog television is still very much a reality, and in some places will be for years until the FCC sets a deadline for the digital conversion of these stations. Many of these stations operate in rural areas or serve minority or other specialized audiences, perhaps explaining the lack of coverage in the mainstream media.  But, given all the publicity that has been accorded to the "completion" of the conversion, some of these populations may well have been confused by the process.  We’ve writtenabout this issue and how it could have created confusion in smaller markets which have service by both full-power and low power TV stations, here.

The transition of LPTV to digital raises a number of issues – including the ability of these stations to deliver radio-type programming when operating on Channel 6.  As we’ve written, LPTV stations on Channel 6 have been used to provide radio services, as Channel 6 is immediately adjacent to the FM band and can be picked up on most radio receivers..  However, when the ultimate transition of LPTV to digital is completed, the ability of these stations to provide a radio-type service will probably disappear, as the audio system used by digital television will not be picked up by analog radio receivers.

At last Tuesday’s FCC meeting, the Commission adopted a controversial order, over the objection of two Commissioners, that could limit the processing of some applications for improvements by some full power FM stations, and would restrict translator applications, all in the name of encouraging Low Power FM (LPFM) stations to provide outlets for expression by groups that cannot get access to full-power radio stations (see our summary of that action here).  In recent weeks, two ideas have received some publicity providing an alternative outlet for these prospective local broadcasters – and both provide a simple solution (one more immediate and ad hoc than that other), but both leading to the same result – why not just extend the FM band by using TV channel 6?

The current FM band begins at 88.1 MHz, a channel that is actually immediately adjacent to TV Channel 6.  The FCC has for years restricted operations of noncommercial FM stations (which operate from 88.1 to 91.9 on the FM dial) in areas where there are Channel 6 TV stations in order to prevent the radio stations from creating interference to the reception of the TV stations.  That’s while you will often find fewer noncommercial stations, or ones with weaker coverage, in communities that have TV Channel 6 licensees.  TV stations use an FM transmission system for their audio.  Thus, you will also find that most FM receivers (especially ones without digital tuners) will pick up the audio from TV channel 6 if tuned all the way to the left of the dial.  The short-term solution to expanding the FM band came from one broadcaster who noted that fact.
