Fishing For Free TV Signals

Par : Doc Searls
5 avril 2024 à 05:48
By expert acclaim, this is the best antenna for receiving hard-to-get over-the-air (OTA) TV signals

I think I will be the last person in Bloomington to try getting free over-the-air TV from what’s left of all the major networks. But that’s just my style, so roll with me while I explain how I’m hoping to do it, with the antenna above, which I’ll need because here is what the Search Map at RabbitEars.info says we might get here:

We live next door right now, and the top station above, WTIU from Indiana University (our PBS affiliate), comes from a tower you can walk to from here. We can get that signal by using a straightened paper clip for an antenna. (You jam the clip into the center hole of the coaxial connector in the back of the TV.) Even a real indoor antenna connected to the same jack gets nothing else, not even the two stations above with “Fair” signal strength.

But this Televes antenna might do the job because we’re on the slope of a hill that faces the Indianapolis stations that carry CBS (WTTV/4 on 27), ABC (WRTV/6 on 25), NBC (WTHR/13 on 13), and Fox (WRDB/41 on 32)*. These range from 27 to 54 miles away, in roughly the same direction. VHF and UHF signals always gain strength when they hit the faces of hills, similar to how surf builds as it approaches a sand bar or a shore. Also, the Televes DAT BOSS antenna gets great reviews:

I was going to put it in our new attic before the drywall goes up. However, the attic space is low and full of close cross-braces. Worse, the antenna is not small and kinda complicated to fit in a space that’s a web of short 2x4s. Dig:

So it will go on a pole in the backyard and feed a coaxial line that will tunnel through conduit under the yard and inside to the new living room.

But I would like to test it first, preferably with a tuner gizmo I can plug into my laptop. I had one of those for years: the Elgato EyeTV Hybrid TV Tuner stick, which looked like a fat thumb drive,with USB-A at one end and a coax connector for an antenna at the other. It was sold in the ’00s and picked up both analog and digital TV (the Digital Transition was happening then), on every North American channel, and came with good software that ran on Macs and operating systems that have long been abandoned. Far as I can tell there are no replacements that run on current hardware or operating system, other than this one sold in Europe. Far as I can tell, it only works on TV bands over there. But I could be wrong. If anybody knows of a gizmo/softward combo I can use, please tell me. My only other option is to buy or find a cheap TV and try that out. Any advice is welcome. Thanks!


*After the digital transition in 2008, and again with the “repack” after 2016, most TV stations moved onto channels other than their original ones, using less spectrum overall. All the TV channels above 36 were auctioned off, first in 2008 and again in 2018. Most buyers were cellular and other short-range wireless carriers, which have been repurposing the old TV spectrum for 5G and other modern uses. The only station in Indianapolis that didn’t move its channel position was WTHR/13. That one is listed in the chart above as one of the “bad” signals for this location. The Televes antenna is designed specifically for “high band” VHF (channels 7-13) and the remaining UHF (14 to 36) TV channels. It also filters out any 5G signals that the antenna might pick up on what used to be the higher UHF channels. By the way, the old “low band” VHF channels (2 to 6) are still in use in some places, but by very few TV stations.  So it’s not worth it for Televes to design an antenna to pick those channels up. Such an antenna would also be a lot bigger and longer because the low-band elements of the antenna would be much longer.

We Need Whole News

local news

Journalism is in trouble because journals are going away. So are broadcasters that do journalism rather than opinionism.*

Basically, they are either drowning in digital muck or adapting to it—and many have. Also in that muck are a zillion new journalists, born native to digital life. Those zillions include everybody with something to say, for example with blogs or podcasts. As Clay Shirky put it in the title of a very relevant book about our topic, Here Comes Everybody.

An odd fact about digital life is that its world is the Internet, which works by eliminating the functional distance between everybody and everything. Think of this habitat as a giant three-dimensional zero: a hollow sphere with an interior that is as close to zero as possible in both distance and cost for everything on it. This is a very weird space that isn’t one, even though we call it one because space works as a metaphor.

Still, we are all embodied creatures operating in a natural world with plenty of distance and lots of costs. This is why we form communities, towns, cities, organizations, institutions, and social networks of people who see and talk to each other in the flesh.

For more than a century, the information center that held a town or a city together was its newspaper. This is no longer the case. The Monroe Country History Center and the Herald-Times (our local paper) explain the situation in an outstanding exhibit at the Center’s museum called Breaking the News:

If you’re reading this on something small, click on it to see the full-size original.

But hey! There are still plenty of journals, journalists, and news sources here in town, including the Herald-Times. That’s some of their logos, gathered at the top of this page. I also listed them in my last post, calling them all, together, wide news. If their work is well-archived we’ll also have what I call deep news in the prior post.

I suggest that the answer to the question asked by that exhibit—where will it go now?— is whole news. That’s what you get when all these media cohere into both a commons and a market.

And, as it happens, we have some resources for creating both.

One is the Ostrom Workshop at Indiana University, where my wife Joyce and I are both visiting scholars. The workshop carries forward the pioneering work of Elinor Ostrom, who won a Nobel Prize in economics for her work on commons of many kinds. If we’re going to make a whole news commons, the Workshop can be hugely helpful. (So can other folks we know, such as Clay Shirky. Note that the subtitle of Here Comes Everybody is The Power of Organizing Without Organizations. Clay will be here to speak in our salon series at IU in December.)

Another is Customer Commons, a nonprofit that Joyce and I started as part of ProjectVRM, which we launched when I started a fellowship at Harvard’s Berkman Klein Center in 2006. Customer Commons (says here) is “a public-facing organization focused on emerging issues at the intersection of empowered individuals and the public good,” while ProjectVRM is a community with hundreds of developers and others working on new business models that start with self-empowered customers. Within both are business model ideas for journalism that have been waiting for the right time and place to try out. (Examples are intentcasting listenlog and emancipay.)

But the first step for us is getting to know the people and organizations on the supply side of news here in Bloomington, where Joyce and have now lived for two years. We know some local journalists already, and would love to know the rest. If I don’t reach you first, email me at doc at searls dot com.

And, as always, everything I’ve written above is subject to corrections and improvements, so I invite those too.


*Put simply, journalism’s mission is to get stories right, while opinionism’s mission is to get and keep an audience. But it’s sometimes hard to tell the difference, because the same labels can apply to both, and even the best journalism rests to some degree on opinions—of experts and eyewitnesses, for example.

You can see how blurry this can get by looking at Nielsen’s ratings for radio stations. Here is a table of Nielsen’s top twenty-five markets, with links to each station with a measurable audience, and labels for each station’s format. As you look at each market, click on the station link to see what’s behind its “News/Talk,” “News,” or “All News” label:

For example, in Dallas-Fort Worth, KERA and WBAP are both “News/Talk.” But KERA’s schedule is built around NPR programs while WBAP’s schedule is built around conservative talkers. Listen to both to draw or re-draw your own conclusions.

News/Talk, however, is at most a very small part of whole news, which is about how no one source of good information owns the whole space, as newspapers used to do. We haven’t yet defined this space, which is why we need to talk about it.

 

 

A look at broadcast history happening

Par : Doc Searls
12 juillet 2023 à 18:09

When I was a kid in the 1950s and early 1960s, AM was the ruling form of radio, and its transmitters were beyond obvious, taking the form of towers hundreds of feet high, sometimes in clusters formed to produce directional signals favoring some directions over others. These were typically landmarks out on the edge of town, or standing oddly on salt bogs or farmland.

From my bedroom in New Jersey, not far across the Hudson from New York City, I could see the red lights on the tops of towers standing in the “Meadowlands” (we called them swamps then) with Manhattan’s skyline beyond.

The towers in the photo above are three of those, tasked with beaming WMCA/570 and WNYC/820 toward New York’s boroughs from a pond of impounded water beside the Hackensack River and the east spur of the New Jersey Turnpike. Built in 1940, these three towers have by now become the most-seen AM radio signal source on Earth. For a while, they were also the most heard. That’s because, in its prime, which ran from 1958 to 1966, WMCA was also the leading top 40 music station in the world’s leading radio market. (WABC, with a signal ten times as strong, ruled the suburbs, with a night signal heard across half the country.)

While these days WNYC is the AM side of New York’s public radio empire (which brings in more money, largely from listeners, than any of the commercial stations in town), it is most famous for Mayor Fiorello LaGuardia’s “Talk to the People” show, which ran in the first half of the 1940s. (Back then WNYC had its own towers standing on what’s now WNYC Transmitter Park, alongside the East River in Brooklyn.)

Prior to the Internet, major media comprised a fewness of sources, in both print and broadcast. That fewness is over now, and the writing of over-the-air broadcasting’s end is being written on the Internet’s walls, perhaps most purposefully by yours truly. Because I’ve shot and shared thousands of photos of transmitters and antennas, knowing that the land under the most vulnerable ones—those on the AM band—tends to be worth more than the signals themselves. Many of these sites have already been sold off, with signals moving to shared towers on other stations’ sites, or just going dark.

Radio itself is also slowly being eaten alive: on the talk side by podcasts and on the music side by streaming services and webcasters. So I publish those photos as historical evidence of what in a few years (decades at most) will be no more. (Sorry, but no amount of lawmaking or regulation will save AM radio. Much as many of us—me included—still love it, neither the tech nor the economics can compete with the Internet, smartphones, the cellular system, and computers.)

So I recently ran a test of a theory: that it is good to have a conversation about all these developments, at least among professionals both active and retired in the broadcast engineering world. What follows is a post I put up for a private group that includes more than a dozen thousand of those.

Some hopefully fun detective work.

First, an ad in the November 14, 1949 issue of Broadcasting, the Youngstown-based company that built (or supplied steel) for countless AM stations in that band’s golden age. The image is of the array of six 400-foot tall self-supporting towers putting out the directional night signal for WFMJ, now WNIO/1390. HT for scanning and publishing that page goes to David Gleason, who gives us the amazing and valuable [https://worldradiohistory.com/](https://worldradiohistory.com/)

Second is a Google StreetView of what I think is the current view of the same site, with the transmitter shack and the six towers replaced. One of those is also a tower in WKBN’s own directional nighttime array. (Also, in the distance is another tower that appears not to participate in either station’s system.)

Third is a Bing Birds Eye (a fixed-wing aircraft) view of the whole site:

And a fourth is the Google view from space of the same.

Of possible relevance is that WNIO and WKBN are non-directional by day, the former from a tower at another site in town. Also that WNIO was a 5kw DA-N from the site for most of its life and is now 9.5kw from the day site and 4.8kw from the night site we see in these images—and that its six towers have six different electrical lengths, ranging from 105.8° to 215.1°, apparently in slightly different positions on the ground. Also that WKBN has been 5kw day and night since the late 1940s.

We can also see from the Truscon ad that the original address of WFMJ was on Poland-Broadmans Road, which I think is now just Broad. (The current shack for WNIO is on East Western Reserve Road, while WKBN’s is at the end of a long driveway off that same road.) One can also see from above something of the entrance off broad and possibly something of the original footprint of the original tower layout.

So, some questions are:

1) Is the first photo from the entrance to the site in the Truscon ad?
2) When did WKBN show up, or was it already at this site?
3) Are the different lengths of towers in the current WNIO array the result of more efficient towers in it, and also why the 4.8kw signal roughly matches the old 5kw footprint on the ground?
4) In 1949, were six towers about the limit of what one could do with a directional array using long math, trig tables, and graph paper, and perhaps a record number for its time?
5) Was Truscon the outfit that pioneered narrow rather than fat towers, and ones with three sides rather than four?

There are other variables, of course. But I just enjoy this kind of detective work, and I’m kinda chumming the waters to bait others who like to do the same. Thanks in advance.

We’ll see who rises to the bait and with what.

[Later…] Old pal Scott Fybush pointed to one of his transmitter visit reports and added this:  “Summary: the current WNIO night site is not the original 1949 six-tower site. That was on what’s now Boardman-Poland Road (US 224) at what’s now the Shops at Boardman Park strip mall. It succumbed to development in the early 1990s, at which point 1390 moved to what’s now its current day tower. The current six-tower night array on Western Reserve Rd. was built in 2003, next to the 1977-vintage WKBN array. WKBN’s original DA was at the WKBN studios at 3930 Sunset, which is still the WKBN-TV facility.”

Given that radio’s content (as we now call it) is gone at the speed of short-term memory (unless it’s recorded, which mostly it isn’t), this kind of reporting may be the only history it has. So, if history matters, this kind of inquiry also matters.


The top photo is one of many I’ve shot on en route to EWR (Newark Liberty International Airport). By the way, these towers were built when one could walk on the land there. One needed boots and a scythe, but it was possible. The water was impounded in the 1990s, I think. Here are some shots from a visit to the site nine years ago.

FM Stations Down on Gibraltar Peak

Par : Doc Searls
12 janvier 2023 à 20:21

[Update: 11:20 AM Wednesday 18 January] Well, I woke this morning to hear all the signals from Gibraltar Peak back on the air. I don’t know if the site is on generator power, or if electric power has been restored. This pop-out from a map symbol on Southern California Edison’s Power Outage Awareness Map suggests the latter:

However, I am listening right now to KZSB/1290 AM’s FM signal on 96.9 from Gibraltar Peak, where the show hosts are detailing many road closures, noting that sections of Gibraltar road are “down the hill,” meaning not there anymore, and unlikely to be fixed soon. I think I also heard them say their FM transmitter is on generator power. Far as I know, they are the only station covering local road closures, buildings damaged, farms and orchards damaged, and related topics, in great detail. It’s old-fashioned local radio at its best. Hats off.

Looking at the power requirements up there, only two stations are high-power ones: KDB/93.7’s transmitter pumps 4.9kW into a stack of five antenna bays that yield an ERP (effective radiated power) of 12.5kW, and KDRW(KCRW)/88.7 uses about 5.9kW to produce 12kW ERP through a stack of four antenna bays. Those are on the poles at the right and left ends of this photo, which I shot after the Jesusita Fire in 2009:

All the other stations’ transmitters require less wattage than a microwave oven. Three only put out ten watts. So, given typical modern transmitter efficiencies, I’m guessing the site probably has a 20kW generator, give or take, requiring about 2.5 gallons of propane per hour. So a 500-gallon propane tank (a typical size) will last about 200 hours. Of course, none of that will matter until the next outage, provided electrical service is actually restored now, or soon.

[Update: 3:34 PM Monday 16 January] Two news stories:

  1. Edhat: Gibraltar Road Damage., by Edhat staff, Januraly 11, 2023 12:30 PM. It’s a collection of revealing Gibraltar Road photos that I wish I had seen earlier. Apologies for that. This is the text of the whole story: “A resident of Gibraltar Road shared the below photos from the recent storm damage. A section of the road appears to be washed out with a Tesla trapped under some debris. The Tesla slide is located approximately a quarter mile past the Rattlesnake Canyon trailhead and the washed road is about a mile past the radio tower before reaching the west fork trailhead.” If “mile past” means going uphill toward East Camino Cielo on the ridge, that means travel was (and is) impeded (at the very least) in both directions from the transmitter sites. The photos are dramatic. Please check them out.
  2. NoozhawkSeveral Radio Stations Still Off the Air After Storm Knocks Out Power to Gibraltar Transmitter Site by Giana Magnoli, by Managing Editor Giana Magnoli, January 16, 2023 | 1:47 pm

From the Noozhawk story:

  • “… they’ve helicoptered up a new battery and 600 gallons of diesel fuel to the site’s backup generator, but they haven’t been able to get it to work.” I believe this is for lack of the expected banjo valve. (See below.)
  • “Southern California Edison, which supplies power to the transmission towers site, first reported an outage for the Gibraltar Road area at 2:34 a.m. Jan. 9, the day of the big storm.” That was Monday. At least some stations would have switched over to generator power then.
  • “Repair crews haven’t been sent to the site yet, according to the SCE Outage Map, but Franklin said he heard there could be new poles installed this week.” That’s John Franklin, who runs the whole Gibraltar Peak site.
  • “KCLU (102.3 FM) went off the air on Wednesday and was still off as of Monday.KCLU (102.3 FM) went off the air on Wednesday and was still off as of Monday. KJEE (92.9 FM) went down for several days but came back on the air on Thursday.” Note: it’s not on now—at least not on the radios I’m using.
  • “Santa Barbara County spokeswoman Kelsey Gerckens Buttitta said there are cell and radio station towers off Gibraltar Road that requires fuel to operate, and Gibraltar Road and East Camino Cielo Road are closed because of slides, debris and slipouts.” Fixing those roads will be very difficult and time-consuming.

The story also lists signals I reported off as of last night. One correction to that: K250BS/97.9, which relays KTMS/990, is on the air. This I presume is because it’s at the KTMS/KTYD site. All the signals from that site (which is up the road from Gibraltar Peak) are still up. I assume that’s either because they are fed electric power separately from Gibraltar Peak, or because they are running on generator power.

[Update: 11:40 AM Monday 16 January] In a private group discussion with broadcast engineers, I am gathering that a stretch of Gibraltar Road close to the Gibraltar Peak site has collapsed. The location is 34°28’05.2″N 119°40’21″W, not far from the road into the transmitter site. This is not the section marked closed by Santa Barbara County on its map here. It is also not an easy fix, because it appears from one photograph I’ve seen (shared on a private group) that the land under the road slid away. It is also not the section where power lines to the site were knocked out. So we’re looking at three separate challenges here:

  1. Restoring electrical service to Gibraltar Peak, and other places served by the same now-broken lines
  2. Repairing Gibraltar Road in at least two places (the one marked on the county map and the one above)
  3. Getting generators fueled and fixed.

On that last issue, I’m told that the site with most of the transmitters can be powered by a generator that awaits what is called a banjo valve. The KDB facility requires propane, and stayed up longer than the others on the peak while its own supply held up.


Gibraltar Peak isn’t the highest landform overlooking Santa Barbara. At 2180 feet, it’s about halfway up the south flank of the Santa Ynez Mountains. But it does provide an excellent vantage for FM stations that want the least obstructed view of the market’s population. That’s why more local signals come from here than from any other site in the region.

Except for now: a time that began with the storm last Tuesday. That’s when power lines feeding the peak were broken by falling rocks that also closed Gibraltar road. Here is a list of signals that have been knocked off the air (and are still off, as of the latest edit, on Sunday, January 15 at 11:15PM):

  • 88.7 KDRW, which has a studio in Santa Barbara, but mostly relays KCRW from Santa Monica
  • 89.5 KSBX, which relays KCBX from San Luis Obispo*
  • 89.9 K210AD, which relays KPCC from Pasadena by way of KJAI from Ojai
  • 90.3 KMRO-FM2, a booster for KMRO in Camarillo
  • 91.5 K218CP, which relays KAWZ from Twin Falls, Idaho
  • 93.7 KDB, which relays KUSC from Los Angeles (down after running on generator power for 5 days)
  • 96.9 K245DD, which relays KZSB/1290 AM in Santa Barbara
  • 97.9 K250BS, which relays KTMS/990 AM in Santa Barbara (and is on a KTMS tower, farther up the slope)
  • 98.7 K254AH, which relays KPFK from Los Angeles
  • 102.3 KK272DT, the FM side of KCLU/1340 in Santa Barbara and KCLU/88.3 in Thousand Oaks

KTMS/990AM, KTYD/99.9FM, and K231CR/94.1, which relays KOSJ/1490AM, are still on the air as of Sunday night at 11:15pm. Those are are a short distance farther up Gibraltar Road. (In the other box in the photo above.)

Here is a guide to substitute signals for some of the stations:

  • KCRW/KDRW can be heard on KCRU/89.1 from Oxnard (actually, Laguna Peak, in Pt. Magu State Park)
  • KDB can be heard on KDSC/91.1 from Thousand Oaks (actually off Sulphur Mountain Road, south of Ojai)
  • KCLU can be heard on 1340 AM from Santa Barbara and 88.3 FM from Thousand Oaks
  • KPCC can be heard on KJAI/89.5 from Ojai (also transmitting from Sulphur Mountai Road)
  • KSBX/KCBX can be heard on 90.9 from Solvang (actually Broadcast Peak)
  • KPFK can be heard on its home signal (biggest in the U.S.) from Mount Wilson in Los Angeles at 90.7
  • KZSB can be heard on 1290 AM from Santa Barbara
  • KMRO can still be heard on its Camarillo main transmitter on 90.3

The two AM signals (marked green in the top list above) are strong in town and most of the FMs are weak but listenable here and there. And all of them can be heard through their live streams online.

Published stories so far, other than this one:

The Independent says the site is a “relay” one. That’s correct in the sense that most of the stations there are satellites of bigger stations elsewhere. But KCLU is local to Santa Barbara (its anchor AM station is here), and the ratings reflect it. I wrote about those ratings a few years ago, in Where Public Radio Rocks. In that post, I noted that public radio is bigger in Santa Barbara than anywhere else in the country.

The most recent ratings (Spring of 2022), in % shares of total listening, are these:

  • KDB/93.9, classical music, relaying KUSC/91.1 from Los Angeles: 7.9%
  • KCLU/102.3 and 1340 in Santa Barbara (studios in Thousand Oaks), public broadcasting: 7.3%
  • KDRW/88.7 in Santa Barbara (main studio in Santa Monica, as KCRW/89.9): 4.6%
  • KPCC/89.9, relaying KJAI/89.5 and KPCC/89.3 in Pasadena: 1.3%
  • KSBX/89.5, relaying KCBX/90.1 from San Luis Obispo: 0.7%

Total: 21.8%.

That means more than a fifth of all radio listening in Santa Barbara is to noncommercial and public radio.

And, of all those stations, only KDB/KUSC and KCLU-AM are on the air right now.

By the way, when I check to see how public broadcasting is doing in other markets, nothing is close. Santa Barbara still kicks ass. I think that’s an interesting story, and I haven’t seen anyone report on it, other than here.


*Turns out KSBX is off the air permanently, after losing a coverage battle with KPBS/89.5 in San Diego. On December 29, they published a story in print and sound titled Why is 89.5 KSBX off the air? The answer is in the atmosphere. They blame tropospheric ducting, which much of the time makes KPBS come in like a local signal. Also, even though KPBS’s transmitter on Soledad Mountain (really more of a hill) above the coast at La Jolla is more than 200 miles away, it does pump out 26,000 watts, while KCBX puts out only 50 watts—and less in some directions. Though the story doesn’t mention it, KJAI, the KPCC relay on 89.5 for Ojai, is audible in Santa Barbara if nothing else is there. So that also didn’t help. By the way, I’m almost certain that the antenna identified as KSBX’s in the story’s photo (which is also one of mine) is actually for KMRO-2. KSBX’s is the one on the left in this photo here.
