Radio Survivor

To some it may seem like I’ve been beating a dead horse over the TV channel 6 on FM issue, but I can’t help but be fascinated with TV broadcasters taking such pains to be on what so many observers say is the dying medium of radio.

In my second missive on the channel 6 radio phenomenon back in June I took note of Schenectady New York’s WRGB-TV. That station’s director of engineering made clear his intention to keep WRGB’s analog audio signal going even after the digital transition.

Now some ten weeks after the June 12 analog shutoff WRGB’s little experiment has come to an end. According to a brief statement posted to the station’s website dated August 24, general manager Robert Furlong acknowledges that this digital TV station has no authorization from the FCC to continue an analog broadcast on the FM dial, and announces the FM broadcast has been turned off, “effective immediately.”

I’ve not turned up any additional explanation for killing it so suddenly. My guess is that the station got a pretty firm message from the FCC reminding them that the license to broadcast an analog signal of any kind expired on June 12. I can’t see how WRGB continuing its 87.7 FM broadcast can be seen as anything but unlicensed operation, which would earn any other unlicensed broadcaster an FCC nastygram, at the very least.

Furlong also says that the station management “reviewing our options,” though I can’t really imagine what those options might be. They could petition the FCC to let them resume the analog broadcast, but that’s a very long longshot. Or perhaps they could reach an arrangement for simulcast with a desperate local radio station. Yet that option quickly gets complex, since I’m certain all of WRGB’s network affiliation and syndication agreements are for TV broadcast only. Adding a real radio simulcast would likely require renegotiating all of those contracts.

The appearance of analog TV’s channel 6 on the far left end of the FM dial was not designed in. Rather it was a happy accident which provided some listeners with an extra channel of programming and some other broadcasters an opportunity to sneak onto the FM dial. Like many such accidents, it might have been good while it lasted, but the sun seems to be setting for channel 6 on FM.

Following up on last week’s post about LPTV stations on channel 6 effectively turning into radio broadcasters I’ve been researching the topic a bit more. Turns out that full-power TV stations had the option to stay on channel 6 in their transition to digital, as I learned from this April article in TV Technology. Although their channel space still bumps up against the low end of the FM dial, the don’t retain their analog audio, and so are no longer heard on the radio.

Interestingly, Fred Lass, the director of engineering for Schenectady, NY’s WRGB-TV, tells TV Technology that he’s considering methods for continuing to have an analog FM audio broadcast alongside the station’s digital signal:

“We have a plan to continue operating on 87.7 after we go digital,” he said. “We think that it’s possible to operate with a vertically polarized analog FM audio carrier when we go back to ch. 6 for DTV. That signal will be horizontally polarized, of course, and there should be enough cross pol isolation to make it work.”

Lass admits that he really hasn’t tried this yet, but thinks it should work.

It never occurred to me that DTV stations would be permitted to continue broadcasting an analog FM audio signal, and I wonder if this is something that would require permission from the FCC.

A couple of weeks ago I was scanning the FM band as I made my short commute from my far-north Chicago neighborhood to WNUR in Evanston for a station meeting. At the bottom end of the dial I encountered a fading station playing a steady stream of smooth jazz with no DJ. I’d never heard the station before and I pretty much know every noncommercial station on the north side of Chicago and north shore ‘burbs. My first assumption was that it was a pirate station, perhaps run by a disaffected smooth jazz fan in protest of the recent loss of format stalwart WNUA.

WLFM 87.7FM & Channel 6

Still listening to the station on the way home I heard commercials, but still no station ID, leaving me more confused. Listening a bit longer at home gave no more clues, so the internet I did search. I quickly learned that the station at 87.7 FM is not a radio station, but actually TV channel 6, WLFM-LP. And I was right that the broadcast was a direct reaction to the shuttering of WNUA.

You see, analog TV channel 6 bumps right up against the bottom of the FM radio dial. TV sound is also frequency modulated, just like radio, so the sound for channel 6 can be heard at the very bottom of the dial. But, you might be thinking, “didn’t analog TV go away on June 12? Wouldn’t that kill WLFM?” Well, if you’re talking about a full-power station on channel 6, you’d be right. But WLFM is a low-power TV station (LPTV) and the digital changeover didn’t happen for LPTV.
