The quick disconnect LNB:
This happened recently at an AM station we were doing work for. It seems the modulation monitor was not working when connected to the backup transmitter. A quick check of the RG-58 coax showed that I had the correct cable plugged into the monitor selector relay. Another check with an ohm meter showed the cable was okay. Then I looked at the connector on the monitor port of the transmitter and saw this:
Looks like the pin is too far back in the connector. This is an old style BNC connector with a solder in center pin:
The center pin has a blob of solder on it, preventing it from seating properly in the connector body. I could have lopped it off and applied a new crimp on connector, but my crimp tool was in the car. I didn’t feel like walking all the way through the studio building, out into the parking lot and getting it. Therefore, I used a file and filed off the solder blob then reassembled the connector:
The transmitter was installed in 1986, I think the connector had been like that for a long time.
It may seem like a small detail to have the modulation monitor working on the backup transmitter, however, the modulation monitor is also the air monitor for the studio. Switching to the backup transmitter but not having a working air monitor would likely have caused confusion and the staff might think they are still off the air. I know in this day and age, a lot of station do not even have backup transmitters, but when something is available, it should work correctly.
I like my cool network analyzer and all that, but sometimes it is the Mark 1, Mod 0 eyeball that gets the job done.
In light of recent events…
You know, in this day and age, one can subscribe to certain ideas or religious viewpoints and pull some pretty serious shit. You might even get away with it. That being said, here is a bit of advice: Do not fuck with Canada.
Things seem to be relatively quite these days, no earth shattering developments, no big news stories, etc. My work load consists of mostly driving to one location and cleaning things up, then driving to another location and cleaning more things up. Nothing really new to write about. However, industry wide, there have been some developments of note:
That is what we hear coming from NOAA All Hazards radio station WXL-37 these days. It has been off the air for the last thirty days or so. I suppose a 91% (or less) up time is acceptable in these circumstances. This is the NOAA radio station that is supposed to cover the mid-Hudson Valley area just north of NYC. It’s a good thing there are no potential hazardous conditions out there this time of year. Nope; no need to worry about tornadoes, hurricanes or even severe thunderstorms. Not to mention any of the other potential hazards in the Hudson Valley. It is not like a tornado ripped through an elementary school and killed a bunch of kids. Nobody from the area was ever stuck by lightning. We do not get hurricanes, ever, ever, ever. No earthquakes, forest fires, there are no nuclear power plants nearby. No child abductions, never ever any terror attacks, hijackings, civil unrest, wide spread power outages, etc. It is not like any public schools, private schools, fire departments, county EOC’s, broadcast LP-1 and LP-2 stations, or cable head ends are monitoring this station anyway. Nope. Not at all.
The question that should be asked is why do we even need NOAA All Hazards radio station WXL-37? That is a good question in light of the fact that the station has been off the air since July 26th. After all; we, the tax payers, are paying for this. So… what are we paying for?
To answer this question, one needs to understand how government employment works. We are paying for some bureaucratic, paper pushing pencil neck geek to check another day off the calendar on the road to his or her retirement. Whether or not any work gets done on that day is strictly coincidental. Working for the government means that the ultimate supervisor is a nameless, faceless, grinding bureaucracy that does not tolerate procedural deviation and wields ultimate power by threatening the loss of pension. Original thought is to be scrubbed out of the system. Continued original thought will activate the explosive chair wheels which will then propel the former employee out of the door with the aforementioned loss of pension condition.
When the station first went off the air, we took the network analyzer up to the site and basically fabricated an antenna to work on 162.475 MHz. We were able to get the station back on the air with 200 watts, however; we did the wrong thing. Even though this is enough power to hit the cable head end, the LP-1 stations and at least two of the county EOC’s, turn it off. This was not a part of the plan. It makes no difference that the primary source for emergency weather information is off the air for four weeks in the middle of thunderstorm season, must stick to the plan, no exceptions.
Makes sense to me.
Broadcast Engineering from a contracting stand point requires a lot of driving. I mean a lot of driving. Since switching from full time Director of Engineering to a contracting field engineering position, I have already worn out two vehicles. Having reliable transportation is a key component of this job. Of course, the other consideration is the price of gasoline which can range from expensive to horribly expensive depending on the warring or not warring that is currently taking place.
Thus, when it came time to replace my strange looking but roomy and reliable Scion xB, I did some research. My complaint about the xB, other than the looks, was lack of ground clearance and lack of all wheel or four wheel drive. After a bit of reading, it seemed the Subaru Crosstrek XV was a good choice. Long story short, I got my car last week and got a pretty good deal, as the car dealer was looking to get rid of all their 2014 stock.
As I was leaving the dealership, the salesman had one final question. The conversation went something like this:
Sales guy: “Mr. Thurst, can I ask what it was that sold you on this car?”
Myself: “Sure, it was the oil filter.”
Me: “The oil filter.”
SG: “No, I heard that, I just don’t understand. It wasn’t the price or the fuel economy or the features?”
Me: “Nope. To be honest, you did give me a good price, I like the all wheel drive, the ground clearance, the gas mileage and all that. But when I popped the hood to look at the engine and saw the oil filter, I was sold.”
SG: “No one has ever said that before. Welp, good luck and thanks for buying your car from us.” (now walking backwards into the dealership, smile fixed on his face and nodding slowly)
Here is a picture of the Subaru FB20 boxer engine:
See the oil filter right next to the oil fill plug, up right and easy to get to. Not only that, some design engineer put a catch basin around the filter mount, knowing that when the filter was unscrewed, all the oil would run out of it. Without the catch basin, that oil would run down the engine block creating a mess that would get worse with each oil change.
Little things. Little things mean a lot.
Alternate title: Less is more (and other non-sense)!
The NAB has come out with their latest interesting opinion on radio station ownership in comments to the FCC regarding the 2014 Quadrennial Regulatory Review. They state that “Retaining the local radio ownership rule unchanged would be arbitrary and capricious” because the audio market place has changed radically over the last ten years. The introduction of online listening via Pandora seems to have created competition that can only be adequately dealt with by further consolidation, it seems. Also, the Commission cannot demonstrate that the current rules promote localism or viewpoint diversity. That last sentence is a fair statement. What the NAB does not say is that there is no evidence that further consolidation will promote localism or viewpoint diversity either.
The comment then goes into a lot of information and statistics on smart phone usage; who has them, what they are using them for et cetera. It is very interesting to note that there is no reason given for the sudden and alarming upswing in mobile online listening. But, let us examine a few interesting data points first:
Let us assume that the average commute to work these days is one hour. That would mean two hours per day of driving and mobile listening. That adds up to 1.16 GB of data per month just in on line listening. Assuming that the smart phone functions as more than just a radio and will be used for email, maps, news, web browsing and other downloads, a fairly hefty data plan would be required of the smart phone user to accommodate all this data. Why would somebody pay considerably extra per month just to listen to online radio?
Do you get where I am going with this? Good, compelling programming is what people are searching for. If they cannot find it on the radio, they will go elsewhere. Nature abhors a vacuum. Want to compete against Pandora, Spotify, XM or whoever? Offer up something good to listen to. These days, competition seems to be a dirty word. Yes, competition requires work, but it, in and of itself, is not bad.
The NAB seems to be saying that relaxing ownership rules and thus, presumably, allowing more consolidation will promote diversity. In my twenty five years of broadcasting, I can say that I have never seen this to be the case. Some of the most diverse radio stations to be heard are often single stations, sometimes an AM/FM combo, just out there doing their thing. Stations like WDST, WHVW, WKZE, WHDD, WJFF, WTBQ, WSBS, WNAW… I am sure that I am forgetting a few.

No two days are alike. Sure, there are days that are similar in nature, office work, filing, FCC compliance, etc. However, there is always something different, some new problem, person, fault, error, client, site or situation to deal with. It helps to be well versed.
So, when the tower climbers started climbing a 1,000 foot (304 meter) tall tower to find a damaged section of transmission line, I thought; Just a routine day.
Even when they encountered a hornet’s nest at 50 feet (15 meters) AGL, still, fairly routine:
Tower climber A received a nasty bee sting to his left arm. He climbed part way down the tower and is in the lower part of the picture hugging the tower face. Tower climber B moved up and killed the nest with Wasp and Bee killer. All is well and work resumes, right? Except, no. Tower climber A is apparently allergic to bees. He states he is not feeling well and his arm begins to swell up. He comes down the tower and I start looking for Benadryl.
Now, we have a problem. This is a mountain top tower site, there is a long dirt road with a locked gate at the bottom of the hill. There is almost no way an ambulance will be able to find its way up here. The tower climber says the he has not been stung in many years. I also notice his face is beginning to swell up. Right, so lock the door, in the truck and get to the bottom of the hill as fast as possible. It took about five minutes, but at the bottom of the hill, we were in a much better position if things got worse and an ambulance needed to be called. Fortunately, his condition was the same, so we drove to an urgent care facility were he was treated.
Benadryl, something else to add to the go bag.
Always keep ahead of the situation. Even if we drove to the bottom of the hill and his symptoms completely disappeared, it still would have been the right decision.
Update: Apparently the pictures in this post have upset some people. Even though there is no identifying information; no call letters, no company name, no location given certain folks have been putting a lot of pressure on the guy I work for. I do not want to make any problems for him, so I removed the pictures. After all, the last thing we would want to do is acknowledge there is a problem. The commentary stays.
Well, we have returned from our semi-vacation. Sumat to do with the other side of the family; a road trip to Canton, Oklahoma, a brief study on mineral rights, then a family reunion. On the return home, several side trips to interesting things like the Abraham Lincoln museum in Springfield, Illinois and the Gateway Arch in Saint Louis. We also stopped in Springfield to see Santa Anna’s leg, which seems to be generating some controversy of late. I do not like to announce such things ahead of time because it seems like an invitation for a house break in.
But, all good things come to an end, so back to work it is.
And then there is this:
A transmitter site for a group of stations not too far from here.
Class B FM station (50,000 watt equivalent) running 100 watts.
And filth, lots of filth.
As more full time broadcast engineers drop off line, we seem to be picking up more and more work. That is good for business, but some of these sites are downright depressing.
It is very sad to see such disrepair and makes me think that we are in the last days of terrestrial radio. Truth be told, the end may be many years off, but the decline gets steadily steeper every year. In the end; Television, Video, Satellite, the internet and took small bites of radio, but radio owners are the true culprits when it comes to who killed radio.
It is hard to make predictions; so many have failed in the past, but ten years maybe. Perhaps a few more. It will depend on whether or not business still find value in radio advertising. Right now that looks pretty far fetched, but who knows…
Today is July 4th. We here in the United States like to remember this as the day when a bunch of upstart yokels from the colonies had the unmitigated gall to decide we wanted to rule ourselves. Terrible thing, that. It sets a bad precedent for the other subjects, some of whom may decide that they want self rule as well. Allow that to happen and pretty soon, the whole empire will be in shambles.
So, there was a war.
It became pretty brutal in this area; loyalists and indians banded together to pillaged the countryside. Families massacred, women shot down, children scalped, old men hung from trees, etc. Part of the local history, although not really the stuff they teach in school these days. It happened, none the less.
Therefore, we celebrate our independence and revel in our freedoms that were so hard won. Freedoms to do things like speak our mind, own firearms, enjoy limited government intrusion in our lives. As human beings, we have rights to legal safeguards that ensures the legal system will not be abused. We enjoy the freedom to travel within our own boarders unmolested. We can worship or not worship in anyway we choose.
We are free, for example, to exchange ideas and develop technology that benefits us and others. Free to learn about things like open source software and even help write the code. Imagine my surprise then, to find out by visiting a website called “Linux Journal,” I am now an extremist? I have frequented many such Linux websites, forums, subreddits, and so on over the years, all in an effort to better understand and apply the open source operating system. I am now, apparently, on a watch list.
This is an article from ars Technica that outlines the NSA program: The NSA thinks Linux Journal is an Extremist Forum.
This is an article from the Linux Journal website: Are you an Extremist? WARNING: If you click that link, then clearly you are.
My only conclusion to this is open source software is bad because of TEH TERRORISM!!11!!! Well, that and it appears to be eating into Microsoft’s and Apple’s market share.
So, put me on a watch list and make sure you spell my name right. You can track everywhere I go. Hell, I’ll even making entertaining for you.
Happy Fourth of July, Extremist!
