A few months back I wrote a post with a headline in the form of a question: How will WMAL-AM survive losing its transmitter? Here was my best guess at the time:

To stay on the air, WMAL will need to find replacement acreage, somewhere that allows the signals … to cross as much of the Metro area as possible, meaning it will have to be northwest of town. For that Cumulus will need to either buy land out that way, or co-site with some other station already operating there.

The only two stations with transmitters out there are WTEM (“ESPN 980″) and WSPZ, both sports stations (on 980 and 570 respectively) and owned by Red Zebra Broadcasting (in which the main stakeholders are also those of the Washington Redskins)…

Of those, WSPZ’s site looks like it has more room. It’s in Germantown, about 22 miles from downtown Washington, more than twice the distance from downtown Washington as WMAL’s current site. I suspect the signal patterns could be “tightened” to concentrate energy toward Washington, though, and that might help. But ground conductivity — which matters hugely for AM signals — is poor in Maryland and Virginia, which is one reason AM stations there tend to suck in the ratings.

Now comes word that Cumulus plans to use the WSPZ/570 site. Here are the day and night signal applications to the FCC. The day power will be the same as at the current site: 10000 watts. But the night power will be only 2700 watts, rather than the current 5000 watts. As I expected, the signals both day and night are “tightened” to a headlight beam shining toward the District. The day signal is on the left and the night signal on the right. (Source:



WSPZ has similar day and night patterns, at 5000 and 1000 watts, using the same four towers.

Here is how sees WSPZ’s day and night patterns. Since the two stations are close in frequency (which greatly affects propagation: lower on the dial is better), expect WMAL’s coverage to be about the same as WSPZ’s.

I can’t help but notice — since I follow these things — that the FCC has issued construction permits for three low power FM (LPFM) stations in Santa Barbara:

  • KGSB/92.3, with a 100-watt signal radiating from one of KZER-AM/1250’s two towers east of the airport, and licensed to ST. RAPHAEL SCHOOL, 160 St Joseph Street, Santa Barbara, CA 93111-2367
  • KZAA/96.5, with a 100-watt signal radiating from roughly the corner of Calle Cesar Chavez and Montecito Streets, and licensed to LA CASA DE LA RAZA, 601 E. Montecito St., Santa Barbara, CA 93103
  • KVSB/96.9, with a 100-watt signal radiating from a corner of Salinas and Lou Dillon Lane on the east side of town, and licensed to:SOUTH COAST COMMUNITY MEDIA ACCESS CENTER, 329 South Salinas Street, Santa Barbara, CA 93103

That’s a lot for a town this size. I’ll be interested to see how those go. Also the new FM translators for AM stations in the market:

This completes our test of interest by anybody, even those who live in Santa Barbara, in stuff like this.

Thank you for listening.

ice-floes-off-greenland(Cross posted from this at Facebook)

In Snow on the Water I wrote about the ‘low threshold of death” for what media folks call “content” — which always seemed to me like another word for packing material. But its common parlance now.

For example, a couple days ago I heard a guy on WEEI, my fave sports station in Boston, yell “Coming up! Twenty-five straight minutes of content!”

Still, it’s all gone like snow on the water, melting at the speed of short term memory decay. Unless it’s in a podcast. And then, even if it’s saved, it’ll still get flushed or 404’d in the fullness of time.

So I think about content death a lot.

Back around the turn of the millennium, John Perry Barlow said “I didn’t start hearing the word ‘content’ until the container business felt threatened.” Same here. But the container business now looks more like plumbing than freight forwarding. Everything flows. But to where?

My Facebook timeline, standing in the vertical, looks like a core sample of glacier ice, drilled back to 1947, the year I showed up. Memory, while it lasts, is of old stuff which in the physical world would rot, dry, disintegrate, vanish or lithify from the bottom up.

But here we are on the Web, which was designed as a way to share documents, not to save them. It presumed a directory structure, inherited from Unix (e.g. domain.something/folder/folder/file.html). Amazingly, it’s still there. Whatever longevity “content” enjoys on the Web is largely owed to that structure, I believe.

But in practice most of what we pile onto the top of the Web is packed into silos such as Facebook. What happens to everything we put there if Facebook goes away? Bear in mind that Facebook isn’t even yet a decade old. It may be huge, but it’s no more permanent than a sand dune. Nothing on the Web is.

Everything on the Web, silo’d or not, flows outward from its sources like icebergs from glaciers, melting at rates of their own.

The one exception to that rule is the Internet Archive, which catches as much as it can of all that flow. Huge thanks to Brewster Kahle and friends for giving us that.

Anyway, just wanted to share some thoughts on digital mortality this morning.

As you were. Or weren’t. Or will be. Or not.

bob-kauffmanWhen the Los Angeles Clippers open their first game at home this season, I want them to pause and celebrate their original franchise player: Bob Kauffman, the team’s all-star center for its first three seasons, when they were the Buffalo Braves.

In fact, I think the team should retire Bob’s jersey, #44. For the ceremony the team should also bring out his four daughters, all of whom were also basketball stars: Lara and Joannah at Georgia Tech, Carey at Duke and Kate at Clayton State. Bob died on July 27 at age 69.

Bob was an amazing player to watch, a privilege I enjoyed often as fellow student at Guilford College. Guilford was nowhere before Bob arrived and a powerhouse by the time he left. Same went for the Braves.

At 6-8 and 240, Bob was a big guy, but he played bigger. Here’s what Guilford wrote about him a couple days ago:

Kauffman scored 2,570 points on 64 percent field-goal shooting and collected 1,801 rebounds in his 113-game career, all current school standards. He also holds Guilford marks for career scoring average (22.7 ppg.), single-game rebounds (32), single-season rebounds (698, 1967-68), career rebounding average (15.9), career field goals (943), single-season field goal percentage (.712, 1967-68), single-season free throws (273, 1966-67), career free throws (684) and single-season free-throw attempts (344, 1966-67).

Great stats, but none suggest how tough and intimidating Bob was as a player. I remember watching one Braves game against the Celtics on TV, pleased when the announcer said Bob was the only center in the NBA who knew how to play Boston’s Dave Cowens, straight up. Amazingly, I just found an account of what followed, in 30 Things About Dave Cowens:

…he slugged Guilford’s Bob Kauffman, appropriately nicknamed “Horse,” at the foul line, then patiently waited for Kauffman to swing back. Kauffman hit Cowens so hard Cowens finished the game wearing an eye patch.

And yet he was totally generous: a consummate team player. I remember Bob McAdoo’s first game with the Braves, against the Knicks at Madison Square Garden. Bob grabbed an offensive board he could have put right back in; but instead he kicked it out to the rookie, so the kid could get off his first pro shot.

Bob’s pro career started as what today we’d call a lottery pick: he was taken third in the 1968 draft by the Seattle Supersonics (now the Oklahoma City Thunder) behind future Hall-of-Famers Elvin Hayes and Wes Unseld. But the Sonics didn’t know what to do with Bob. Nor did the Chicago Bulls, where he played the next year.

Then Bob got lucky. Thanks to various trades and player shufflings, he landed with the Buffalo Braves, an expansion team, for their inaugural season. The fit was perfect. Here’s Jerry Sullivan in The Buffalo News:

In the Braves’ first season of 1970-71, Kauffman averaged 20.4 points, 10.7 rebounds and 4.5 assists. He averaged 18.9 points and 10.2 rebounds in ’71-72 and 17.5 points and 11.1 rebounds in ’72-73. He made the Eastern all-stars in all three seasons for Buffalo teams that lost 60 games.

As his daughter Lara put it to Jerry, Bob left his heart in Buffalo:

“The Buffalo fans from all over, people who moved to Atlanta or wherever I go, they all remember my dad,” Lara Kauffman said. “What people remembered about my dad was he played very blue-collar. I think he was sort of a reflection of a lot of people in the Buffalo community the way he played. He wouldn’t back down from anybody. He played against Lew Alcindor at the time. He matched up against Wilt Chamberlain. My dad would go head-to-head with those guys.

“He was undersized. He was 6-8 and played a face-up game. But because he was so physical, oftentimes he would match up against the toughest player. He would go toe-to-toe with them. I think his style of play reflected Buffalo a lot. He was a hard-working player. Every timeout, he ran off the court. He was the first to the bench.

“He tried to set a good example of hard work and play,” his daughter added. “If my dad had a late night the night before with the guys, he was up at 5 a.m. running six miles. He never stopped. He was just a committed athlete. He was also a gentleman. He would sign autographs. He had all the patience in the world with the fans. They were important to him. He never treated people as second-class. He always had time for them.”

And that’s how I remember him as well. Back at Guilford, there wasn’t a bigger man on campus than Bob, yet he was sweet and friendly with everybody.

Bob’s career as a player was sadly short. Hip problems forced him to retire at 28, from the Atlanta Hawks. After that he coached the Detroit Pistons for a year and then returned to the Hawks’ front office before leaving the game for other work. (If memory serves, Bob was the GM for Detroit when they hired Dick Vitale as coach.)

My favorite testimony to Bob’s value as a player was uttered by his coach at Guilford, Jerry Steele. After Guilford’s play-by-play announcer told Jerry that Catawba College guard Dwight Durante (“the best 3-point shooter you never saw“) appeared that week in a Sports Illustrated piece, Jerry replied, in his usual slow drawl, “Well, Dwight Durante may have his picture in Sports Illustrated, but I’ve got Bob Kauffman’s picture in my bedroom.”

The announcer was Carl Scheer, known today as a legendary NBA executive, former GM of the Carolina Cougars, Denver Nuggets, LA Clippers and Charlotte Hornets — and the inventor of the Slam Dunk Contest, among other distinctions. If it weren’t for Bob, Carl might still be a lawyer in Greensboro. Suzanne Dietzel in Greater Charlotte Business:

After a respectable run in undergraduate college basketball and baseball, Scheer graduated from Marquette Law School and began a career in a small law firm in Greensboro. After realizing that his desire to litigate cases would likely be unrealized due to the size of the firm, he visited Guilford College and asked to be slated to broadcast basketball and football games – a passion he had indulged in graduate school.

Scheer had made fast friends with many in the sports community when opportunity knocked. According to Scheer, “Guilford was embarking upon an aggressive, small college basketball campaign, largely driven by star player, Bob Kauffman. I had announced his college career, and once he found himself in demand by two competing leagues, he asked me to represent him for his contract negotiations.”

Scheer elaborates, “In 1968, agents were unheard of. Knowing I was a lawyer, Bob asked me to represent him.” He jokes, “I am sure I left the poor guy quite a bit of money on the table! But, really, the experience introduced me into the world of sports and business; I was hooked.”

Not surprisingly, his work ethic and comfortable personality helped to foster a good rapport with team owners, and he was asked to interview for the position of assistant to the commissioner of the NBA.

Recalls Scheer, “The NBA commissioner at the time, Walter Kennedy, told me after my third interview that he liked me and thought I was a great candidate, but the job was going to ‘the other guy.’ At the time I was content with that. I had had that 15 minutes of glory and was happy to go back to my small North Carolina law firm. But months later he called back and told me the other candidate declined the position, and asked if I would like to be reconsidered. It was a dream come true. I moved to New York and began my indoctrination into the game. There, my sports career started.”

The best lives have the best consequences. I’d like one of Bob’s to be a celebration of his place as the Clippers founding all-star — who also happened to be a four-star dad.



Right now every FM and TV station in Santa Barbara and San Diego can be heard in both places. Between them lays more than 200 miles of ocean across a curved earth. I’m not there right now, but I see what’s happening remotely over my TV set top box. (Thank you, SlingBox.) But, more importantly, John Harder‘s tropo map tells me so:


Tropo is tropospheric refraction of radio waves across a distance. Atmosphere has refractive properties that don’t matter most of the time. But we can see changes, for example, with mirages ahead of us above a hot road, which causes the air above to refract light at a low angle, essentially reflecting the sky, other cars and landscapes on the horizon. Something like this also happens over land and water.

I see by the map above that tropo is happening in other parts of California, Nevada, Utah and Arizona. I also see that it’s starting to happen here in north central North Carolina, where I can already pick up stations in South Carolina:


On 88.1fm, for example, I’m getting WRJA from Sumter, South Carolina, atop WKNC in Raleigh. WRJA is about 160 miles away while WKNC is only 40 miles away. But WRJA is 100,000 watts atop a thousand-foot tower, while WKNC is 25,000 watts on a 260 foot tower. (It’s actually as little as 35% of full power in most directions from the transmitter at NC State. They have a construction permit to change that a bit.) So they’re making a hash of each other here.

Back when I lived in the woods north of Chapel Hill, long before the Internet showed up and made all of this stuff irrelevant for listeners (who can get the same stations on the Net, anywhere), I had a directional Finco FM-5 antenna and a Channel Master Crossfire 3610 antenna (both salvaged from abandoned structures) on a pole next to my 1-story house. I rotated them by hand. If I had the same rig here I could point at either WRJA or WKNC and “null out” the other. I did this on hot summer mornings for fun back then, and eventually logged nearly every FM station from Pennsylvania to Georgia. (It’s a summer thing, and coincidental with heat waves over large areas.)

Here is a whole-country map that shows tropo happening pretty much everywhere:


I would love to have had this kind of resource back in those days. Now that I do, it’s hardly worth the trouble, since nearly all my radio listening is over the Net.

Anyway, if you’re wondering why your local station is being obliterated by a signal coming from a state or two away, or why you’re suddenly getting far-away stations where none were before, tropo is the most likely reason.

The second most likely one is Sporadic E skip, which brings in stations from distances of 800-1200 miles or so away. In that case the E layer of the ionosphere turns into something like a hot road surface, reflecting distant signals, but only at a certain angle. I’ll cover those in a later post when the phenomenon is actually happening. It’s not right now.

Meanwhile, if any of this intrigues you at all, check out William Hepburn’s amazing Worldwide Tropo Forecast Maps. Great eye and brain candy, because it exposes a real-world view of the world that isn’t what you see with your eyes.

The radio dial here IMG_8116in “upstate” Manhattan and the Bronx is packed with pirate radio signals. Many are smack next to New York’s licensed landmarks. Here’s what I’m getting right now on our kitchen radio…

  • 88.1 “Romantica New York” Spanish announcers, music in English and Spanish. Right next to WBGO (@wbgo), New York’s jazz station (licensed to Newark).
  • 89.3 Spanish. Right next to WFDU and WNYU (@wnyu), the Fairleigh Dickenson and NYU stations that share time on 89.1.
  • 89.7 Spanish. Talk. Call-ins. Right next to WKCR (@wkcrfm), the Columbia University station on 89.9.
  • 91.3 Spanish, as I recall. It just popped off the air. Right next to WNYE on 91.5.
  • 92.1 Spanish, currently playing traditional Mexican (e.g. Mariachi) music and talking up a Mexican restaurant. Right next to 92.3 WBMP “Amp radio” (@923amp) in New York.
  • 94.3 Spanish talk. Not next to any local station, but two notches removed from 94.7 WNSH “Nash” (@nashfm947ny) in New York (licensed to Newark).
  • 95.3 Spanish music. Right next to 95.5 WPLJ (@955plj) in New York. (Note that in the screen shot above, of my kitchen radio, it lights up the ST (stereo) indicator.)
  • 98.9 Spanish talk and music. Right next to 98.7 WEPN-FM (@espnny98_7), ESPN’s flagship station on 98.7.
  • 99.3 Spanish talk. Right next to 99.5 WBAI in New York.
  • 101.7 Spanish music. Right next to 101.9 WFAN-FM (@wfan660) in New York.
  • 102.5 English talk, with a Caribbean accent. Just heard ads for businesses in The Bronx (nail salon) and New Jersey (dentist), massage therapy (50 fremont ave, East Orange, NJ), a reggae music concert, 708-282-8741. Right next to 102.7 WWFS, “Fresh 102.7″ (@fresh1027ny) in New York.
  • 102.9 English talk and music, with a Jamaican accent. I believe this was the same station that earlier today was rebroadcasting a Kingston station, no doubt picked up off the Net. Also right next to WWFS.
  • 105.5 Some kind of Christian pop, I think. It’s not WDHA in Dover, NJ. I just checked that station’s stream online. Totally different.
  • 105.7 Music in English right now. Right next to 105.9 WQXR (@WQXR) in New York.
  • 106.1 English. Reggae dance. Ads: Mizama Apparel Plus, 4735 white plains road. Kings Electronics, 4372 White Plains Road. Jumbo concert in Mt. Vernon… Also right next to WQXR on the dial. All but blows QXR away, in fact. (QXR’s signal radiates from the same master antenna as most other New York stations, on the Empire State Building, but is just 610 watts, while most of the rest are 6000 watts.)
  • 106.9 English music. Caribbean accent. Right next to 106.7 WLTW “Lite FM” (@1067litefm) in New York.

This is a nearly completely different list of pirates than the one I compiled last fall from this same location, in the 10040 area code. (There were pirate signals on 89.3 and 89.7 then, but I’m not sure if these are the same.), None of the pirate signals match anything on this list of all the legitimate licensed signals radiating within 100km (60 miles) of here.

Man, I wish I knew Spanish. If I did, I would dig into as many of these as I could.

All of them, I am sure, are coming from the northern end of Manhattan and the Bronx, though 102.5 has so many ads for New Jersey places that I wonder if it’s actually over there somewhere.

All of them serve some kind of marketplace, I assume. And even though I don’t understand most of what they’re talking about (when they do talk), I’m fascinated by them.

At the same time they are all illegal, and to varying degrees interfere with legitimate licensed stations. If I were any of the legitimate stations listed above, I’d be concerned. Weaker stations (e.g. WKCR, WBGO and WQXR) especially.

There are a few New York pirate radio stories out there (here, here and here, for example); but they’re all thin, stale or old.

This is a real phenomenon with a lot of meat for an enterprising journalist — especially one who speaks Spanish. Any takers?

meerkatLook where Meerkat andperiscopeapp Periscope point. I mean, historically. They vector toward a future where anybody anywhere can send live video out to the glowing rectangles of the world.

If you’ve looked at the output of either, several things become clear about their inevitable evolutionary path:

  1. Mobile phone/data systems will get their gears stripped, in both directions. And it will get worse before it gets better.
  2. Stereo sound recording is coming. Binaural recording too. Next…
  3. 3D. Mobile devices in a generation or two will include two microphones and two cameras pointed toward the subject being broadcast. Next…
  4. VR, or virtual reality.

Since walking around like a dork holding a mobile in front of you shouldn’t be the only way to produce these videos, glasses like these are inevitable:


(That’s a placeholder design in the public domain, so it has no IP drag, other than whatever submarine patents already exist, and I am sure there are some.)

Now pause to dig Facebook’s 10-year plan to build The Matrix. How long before Facebook buys Meerkat and builds it into Occulus Rift? Or buys Twitter, just to get Periscope and do the same?

Whatever else happens, the rights clearing question gets very personal. Do you want to be recorded by others and broadcast to the world or not? What are the social and device protocols for that? (Some are designed into the glasses above. Hope they help.)

We should start zero-basing some answers today, while the inevitable is in sight but isn’t here yet.

It should help to remember that all copyright laws were created in times when digital life was unimaginable (e.g. Stature of Anne, ASCAP), barely known (Act of 1976), or highly feared (WIPO, CTEA, DMCA).

How would we write new laws for the new video age that has barely started? Or why start with laws at all? (Remember that nearly all regulation protects yesterday from last Thursday — and are often written by know-nothings.)

We’ve only been living the networked life since graphical browsers and ISPs arrived in the mid-90’s. Meanwhile we’ve had thousands of years to develop civilization in the physical world.

Relatively speaking, digital networked life is Eden, which also didn’t come with privacy. That’s why we made clothing and shelter, and eventually put both on hooves and wheels.

How will we create the digital equivalents of the privacy technologies we call clothing, shelter, buttons, zippers, doors, windows, shades, blinds and curtains? Are the first answers technical or policy ones? Or both? (I favor the technical, fwiw. Code is Law and all that.)

Protecting the need for artists to make money is part of the picture. But it’s not the only part. And laws are only one way to protect artists, or anybody.

Manners come first, and we don’t have those yet. Meaning we also lack civilization, which is built on, and with, manners of many kinds. Think about much manners are lacking in the digital world. So far.

None of the big companies that dominate our digital lives have fully thought out how to protect anybody’s privacy. Those that come closest are ones we pay directly, and are therefore accountable to us (to a degree). Apple and Microsoft, for example, are doing more and more to isolate personal data to spaces the individual controls and the company can’t see — and to keep personal data away from the advertising business that sustains Google and Facebook, which both seem to regard personal privacy as a bug in civilization, rather than a feature of it. Note that we also pay those two companies nothing for their services. (We are mere consumers, whose lives are sold to the company’s actual customers, which are advertisers.)

Bottom line: the legal slate is covered in chalk, but the technical one is close to clean. What do we want to write there?

Start here: privacy is personal. We need to be able to signal our intentions about privacy — both as people doing the shooting, and the people being shot. A red light on a phone indicating recording status (as we have on video cameras) is one good step for video producers. On the other side of the camera, we need to signal what’s okay and what’s not. Clothing does that to some degree. So do doors, and shades and shutters on windows. We need the equivalent in our shared networked space. The faster and better we do that, the better we’ll be able to make good TV.

This is about AM radio stations being worth less than the ground they stand on. Case in point: WMAL-AM in Washington, DC. You can see the problem with this Google Map:


The heart-shaped patch of green between the legs of I-495 and the I-270 spur is populated by four towers radiating the signal of WMAL, a landmark on Washington’s radio dial (at 630am) since 1925. The station’s 75-acre transmitter site is nearly as big as the nearby Bethesda Country Club golf course and the Westfield Montgomery Mall. It also sits deep in the suburbs, surrounded by trees and highways, most of which appeared long after WMAL erected the towers on cheap open land, far from the bustling Capitol, many decades ago. That land is worth a lot more now.

So it’s no surprise to read news (via The Sentinel) that Cumulus Media, which owns WMAL-AM & FM, has put the land up for sale. Says the report, “Local real estate experts estimate the property could be worth hundreds of millions.” I don’t know what WMAL-AM is worth, but I’m guessing it would be a few million, tops. So it makes financial sense to sell off the land. 

But what about the signal? Many AM stations have already “gone dark” (as they say in the business). Will WMAL do the same? In the first comment below, Jon Elbaz, who wrote the Sentinel piece, says Cumulus intends to keep WMAL-AM on the air somehow. But a question is raised: how long can any AM station on desirable land stay on the air? And by what means?

Back in radio’s golden age — when AM ruled the waves — the stations battling for the top of Washington, DC’s ratings heap were WTOP and WMAL. WTOP peaked when it went all-news in the 1960s, and has stayed at the top ever since. It did that by doing great work, and by wisely moving to FM a few years back, taking over the channel (103.5) long occupied by classical WGMS-FM, whose owners by then had unloaded its original 570am signal, which is still on the air as WSPZ. (More about that below.) WMAL also has an FM signal, on 105.9. That one is #9 in Nielsen’s latest figures, while WTOP is #1. WMAL-AM doesn’t show at all.

So I have to wonder about Cumulus commitment to keeping the signal on the air. Finding a new transmitter site is not a cheap undertaking. To explain, I’ll need to get technical.

To transmit, AM radio stations require a substantial sum of real estate. AM waves are hundreds of feet long, and require long radiating antennas. These take the form of towers. If a station has a directional signal, more than one tower is required to create the signal’s pattern. WMAL has two different asymmetrical patterns for use in the day and night. Here is how the four towers are arranged, and the patterns they produce:


Each tower is a quarter wavelength high, which at 630am makes them about 400 feet tall. Surrounding them is also a “ground system” of buried conductors running hundreds of feet in all directions from the towers. This is why WMAL needs those 75 acres. To stay on the air, WMAL will need to find replacement acreage, somewhere that allows the signals you see above (or slightly modified versions of them) to cross as much of the Metro area as possible, meaning it will have to be northwest of town. For that Cumulus will need to either buy land out that way, or co-site with some other station already operating there.

The only two stations with transmitters out there are WTEM (“ESPN 980″) and WSPZ, both sports stations (on 980 and 570 respectively) and owned by Red Zebra Broadcasting (in which the main stakeholders are also those of the Washington Redskins). (Here are aerial views, via Bing, of the WTEM and WSPZ sites.)

Of those, WSPZ’s site looks like it has more room. It’s in Germantown, about 22 miles from downtown Washington, more than twice the distance from downtown Washington as WMAL’s current site. I suspect the signal patterns could be “tightened” to concentrate energy toward Washington, though, and that might help. But ground conductivity — which matters hugely for AM signals — is poor in Maryland and Virginia, which is one reason AM stations there tend to suck in the ratings. (For evidence of how much ground conductivity matters, compare three AM stations, all 5,000 watts, and all on 570am: WSPZ in Washington, WNAX in Yankton, South Dakota and KLIF in Dallas. The latter two cover enormous territories, while WSPZ basically covers the District and bits of adjacent Maryland and Virginia. Ground conductivity in the middle of the country is about 15x better than the area served by WSPZ.)

In fact WSPZ is way out of town today because its owners a few years back did exactly what Cumulus is doing with WMAL today: they sold the land out from under the towers. This topo map shows where the WSPZ towers used to be, when it was still WGMS: a site in Potomac, across the Beltway about three miles from WMAL’s site. Believe me, the old signal from the old site covered the metro a helluva lot better than the new signal from the new site. Expect the same results if WMAL moves there.

So again, why keep WMAL-AM on the air at all?

One argument is that the WMAL-FM signal isn’t a great one. While it’s licensed for 28000 watts, it only hits that max to the northwest and southwest of its transmitter in Merrifield, outside the Beltway on the southwest side of town. Toward the district (northeast of the site) its signal has a huge dent, down to around 1/4 of what it puts out in the other directions:


So getting a bit of help on the AM side might still be worth the trouble.

Still, one wonders… How much time will pass before the land under WSPZ becomes far more valuable than the station — or even WSPZ and WMAL put together?

This kind of question sits in front of many AM station owners’ minds right now. I expect what we’ll have in the long run are AM stations standing on land with little or no market value. The rest will disappear along with their real estate.

[Later…] I also wonder about Cumulus’ commitment to saving the signal. In 2011 it acquired (by merger) KAAY/1090am in Little Rock, Arkansas — a 50,000 watt giant with rich history and a night signal that stretches from Cuba to Canada. Or used to. Wikipedia:

Unfortunately, owners of KAAY in later years allowed the stations famed transmission facilities in Wrightsville, AR to fall into disrepair. Copper thieves stole a large amount of transmission line, degrading the stations signal significantly. Roof damage allowed water to enter the 50,000 watt transmitter – knocking it off the air. Currently, KAAY has reestablished 50000 watt service during the day, but has yet to rebuild the 3 tower directional array, so nighttime service remains under an STA at 1250 watts non directional.

KAAY is the biggest AM station in Arkansas. If Cumulus cared, it would restore the station to full capacity. But the format is “brokered/Christian,” which is tends to be low-cost dial-filler. Only one AM station makes the published ratings for Little Rock, and it’s Cumulus’ KARN/920 “The Sports Animal.” Not KAAY. KARN is also at the bottom of the heap. Higher rated are four other Cumulus stations, all FMs.

So the Company isn’t suffering there. Its portfolio of stations does fine, and that’s what matters, right? If the market won’t miss WMAL-AM, why bother keeping it?

[Later again…] This story features an offer sheet on the property, and says offers need to be in by March 12. I also found this older story, about Cumulus’ plan to sell the land under KABC’s transmitter. I can find no evidence that the land has been sold, or is still on the market. KABC also has no construction permits to move to a new location.

[Later again…] Well, apparently they do think it’s worth the bother. Jonathan O’Connell reported this in a February 13 story in The Washington Post:

When the towers are torn down, it will not affect WMAL, said Cumulus spokesman Collin Jones. Jones said the company would lease transmission facilities elsewhere after the sale closed.

“Listeners will literally have no idea that it happened,” Jones said.

Well, some listeners. Others will. There is no way WMAL can move to another site without compromising the signal in some directions.

[May 5…] A buyer for the land has been found, stories in Bethesda Magazine and Radio World report. In a search on, however, I see no applications or construction permits at a new site, but perhaps Cumulus is still in negotiations for leasing space at other locations.





mutualmusiciansSo I just learned that a Kansas City Jazz station is headed toward existence. If you love any of these musicians, this should be very good news.

The story begins,

By this time next year, Kansas City-style jazz might be bebopping out of a new radio station near you.

The Mutual Musicians Foundation in the 18th and Vine jazz district announced this week it’s been granted a construction permit for a noncommercial, low-power FM radio station. The foundation is hoping the KC jazz station, at 104.7 FM, will be on the air by next January.

It will be called KOJH-LP. LP stands for low power, or what the FCC calls LPFM. Here’s the application for what’s now a granted CP, or Construction Permit.

In fact there is a jazz station called KOJH already — a streaming one in Oklahoma. Though it’s not a licensed radio station, it may have inherited those call letters from one. (I’ve looked, but haven’t been able to tell. Maybe the lazyweb knows.)

Here’s the station’s mission, filed with the FCC.

KOJH will broadcast from the Arts Asylum at Harrison and E. 9th Street. A new tower will go on the building. From there they will radiate a whopping 22 watts at 207 feet above the average terrain, at 104.7fm. It’s a tiny signal that will won’t reach far out of downtown.

Worse, most of Kansas City’s big FM stations have effective radiated powers (what’s concentrated toward the horizon, or populations) of 100,000 watts, and transmit from a collection of towers over 1000 feet tall, just a short distance east of downtown. One of those is KBEQ on 104.3, just two notches down the dial from KOJH. This means you will need a good radio to keep KBEQ from blasting KOJH sideways. Today’s car radios are good enough to keep that from happening. (And will likely get KOJH up to a dozen or more miles away.) Recent-vintage portable and home radios will have a hard time, unless they’re very close to the KOJH transmitter.

(Many manufacturers quit caring decades ago. And now Radio Shack has filed for bankruptcy. Even CEO Can’t Figure Out How RadioShack Still In Business, which ran in The Onion in 2007, has proven prophetic.)

So it is good to know KOJH plans to stream online, because that’s the future of radio.

But there are other stepping stones.

For example, something the Mutual Musicians Foundation might consider doing, while they get underway with KOJH, is buying an AM station that’s dropped out of the ratings. Some possibles, going up the dial:

    • KCCV/760. 6000 watts day, 200 watts night.
    • WHB/810. 50000 watts day, 5000 watts night.
    • KBMZ/980. 5000 watts day and night.
    • KCWJ/1030. 5000 watts day, 500 watts night.
    • KCTO/1160. 5000 watts day, 230 watts night.
    • KYYS/1250. 25000 watts day, 3700 watts night.
    • KDTD/1340. 1000 watts, day and night.
    • KCNW/1380. 2500 watts day, 300 watts night.
    • KKLO/1410. 5000 watts day, 500 watts night.
    • KCZZ/1480. 1000 watts day, 500 watts night.
    • KWOD/1660. 10000 watts day, 1000 watts night.

(Note that wattage is just one variable. Location of the transmitter, efficiency of the towers, directionality of the signal, ground conductivity and frequency all matter too. For example, the lower the station’s frequency, the longer the wavelength, and the better its signal travels along the ground.)

Only three AM stations show up in Kansas City’s latest ratings: KCSP, a sports station at 610am, KCMO, a right-wing talk station at 710am, and KPRT, a gospel music station at 1590am. (With 1000 watts by day and just 50 watts at night, I’m amazed KPRT makes the ratings at all.)

All the un-rated stations listed above put signals across all of KOJH’s coverage area, and then some. Some, such as WHB (a legendary station and signal), may never be for sale. But I’ll bet some others are on the market today, and will only get cheaper.

Music sounds awful on AM, unless the station radiates HD radio encoding. Most engineers I know in broadcasting dislike HD radio and consider it a gimmick. But it does sound quite good on both AM and FM. The difference it makes on AM is amazing.

Loyal listeners of a format will do the work required to get a signal. I’m sure that’s the case with KPRT’s gospel listeners, for example. Now, after stumbling for years, HD radio is picking up with manufacturers. There is a nice list on the HD Radio site. Meanwhile, the market value of AM radio stations, especially ones with no ratings, is crashing to the point where the cost of operating them exceeds their income. (An AM station sucks about twice the wattage off the grid as it radiates from its transmitter.) In coming years many of them will sell for a song.

So those changes — the rise of HD Rado and the decline of also-ran AM station prices — are factors the KOJH folks might want to keep in mind as they fire up their LP signal on FM. Think local, but think big too.

The blizzard hit coastal New England, not New York City. In fact, it’s still hitting. Wish I was there, because I love snow. Here in New York City we got pffft: about eight inches in Central Park: an average winter snowstorm. No big deal.

I was set up with my GoPro to time-lapse accumulations on the balcony outside our front window. I had two other cameras ready to go, and multiple devices tuned in to streams of news stories, tweets and posts. Instead the story I got was an old and familiar one of misplaced sensationalism. Nothing happening, non-stop. At least here.

The real news was happening in Boston, Providence, Worcester, Montauk, Scituate, the Cape and Islands. But I didn’t have anything useful to add to what thousands of others were showing, posting, tweeting and blogging. Back during Sandy, I had a lot to blog because important stuff wasn’t being said on media major and minor. For example I predicted, correctly, that many radio and TV stations would be knocked off the air by flooding. I also thought, correctly, that New York was under-prepared for the storm.
Not so this time, for any of the places the storm has hit.

With the snow still falling over New England…

Screen Shot 2015-01-27 at 8.17.02 PM… there’s a good chance that it will break old records (and probably already has in some places). But the cable news system is a still a broken record: endless pronouncements by undersecretaries of the overstate.

As more cords get cut, and more of us inform each other directly, new and better forms of aggregation and intermediation will emerge. To some extent the major media are already adapting, showing videos, tweets and posts from the Long Tail. But I suspect that the next major shift will be to something different than anything we have now.

I suspect the biggest innovations will be around discovery — of each other. Who has the information I want, now? Who or what is being fully useful, rather than just noisy or repetitive? Search from Google and Bing, while good in many ways, seems hidebound and stale to me. Its personalization is mostly about guesswork that’s hard to figure or control, and is jiggered for advertising as well.

For example, right now I’d like to know more about the breached sea wall in Scituate. Here’s a Yahoo (Bing) search. Most of the top results are at, which says to me — before I even look at any of them — “Oh, is the Boston Globe, and I’ve already run out the five views it gives me on this browser before it thows up the paywall.” In fact there is no paywall for some of the local stories, but I’ve seen it so many times that I don’t want to go there. The second thing I notice is that they’re all old: from 2014 and 2013. When I look for the same thing at Google News, the top results are the paywalled Globe ones. So I search for Scituate on Twitter, which is more helpful, but not fine-grained enough. What if I want to read only people who live there and are reporting from there?

Try to think outside of the search and social media boxes for a minute. Think all the way outside the Web.

Just think Internet, which is nothing more than a way for anybody or anything to connect to anybody or anything. Let’s find a way to do discovery there. We have some crude beginnings with stuff like this. But we need something much more natural, distributed and outside the control of any company or government — as is the Internet, by nature.

Once we have that, all kinds of amazing stuff will start to open up.
