It does not look like much, however, that is about $5,500.00 worth of damage. What you don’t see is the mashed oil cooler and radiator. This happened on my way from one place to another during the early morning hours. I was traveling at about 55 MPH when a deer bolted from the woods and entered the roadway from the right. I did not have time to break.
In a ditch
A momentary lapse of attention causes loss of $80.00. I think I was adjusting the defroster as I was driving down the road when suddenly, I felt the car tilt over to an alarming degree. You can see the tow truck getting ready to pull it out. Fortunately, there was no damage to the vehicle.
Troubles with the neighbor
This is on the access road to one of our transmitter sites. The station has a legal right of way through this property, however, the neighbor seems to object. I spoke with him and showed him a copy of our deed, he has since changed plans.
One side of a balanced audio connection disconnected
This is the downside of using category cable to make audio connections. The wires are not as rugged as say Belden 8451. This was causing problems because it is at an AM studio/transmitter site.
Burned 30 amp three phase contactor
Three phase, 30 amp, 240 volt contactor installed in a 480 volt system. Lasted a few years, anyway.
White face hornets nest
New tenants on one of our towers. This is a white faced (or bald faced) hornets nest. They are really paper wasps, but that difference aside, these beasts are nasty, aggressive and have a painful sting. Normally, I am a live and let live kind of person, but in this case, they gotta go.
Dummy load attached to plywood
This is at one of our AM clients site. Somebody, quite some time ago it seems, made this test load for a 1 KW AM transmitter. It is very nice, carbon ceramic resistors, 50 ohms and surprisingly little reactance. Then they attached it to this piece of plywood. As one can surmise, the load gets quite hot under full power, full modulation conditions. We remounted this in a cage type enclosure and bolted it to the cinder block wall.
Scala PR-950U cross polarized
The client at this station is complaining of intermittent STL drop outs and low signal strength at the receive end. Found this Scala PR-950U antenna mounted for vertical polarization, but the antenna element is horizontally mounted. We’ll call it “vorizontal.”
Ribbon cable from a Cummins 135 KW generator
This was discovered during routine maintenance and thankfully not during a power outage. Mice got into the control box of a newish Cummins 135 KW generator and chewed through what looks like a data buss cable. The generator would not run and the cable and control board needed to be replaced.
There is more bulging capacitors removed from flat panels monitors.
This is a project that we have been working on, weather permitting, for the last month. Basically, it called for installing this Nautel VS2.5 transmitter, mod monitor, remote control and audio processor:
WEXT Nautel VS2.5, Amsterdam, NY
The common thread here; each piece of new equipment has a web interface. More and more, HTTP is being used to monitor and control transmitters, audio processors, STL’s, consoles, satellite receivers, etc. Port 80 services (HTTP) are nice, but I think I would prefer port 443 (HTTPS). Secure HTTP has a whole set of additional requirements, so it is understandable why manufactures do not use it. However, it is only a matter of time until some problem arises…
Nautel VS2.5 Web AUI
Burk ARC Plus web interface
Telos Omnia One web interface
I like the Nautel AUI, especially for any station running HD Radio. In this setup, there are multiple control and monitoring points available via the LAN at the studio. The Omnia One is set up to take the AES input from the Harris IP Link as the main feed and fail over to the analog output from the Inno Tuner as a backup. The Inno is set to WMHT-FM which broadcasts the WEXT format on the HD-2 channel.
This setup is pretty slick, especially in light of the equipment it is replacing:
It is not news that the FCC has its hands full with the FM pirates in the NYC area, particularly Brooklyn. On any given night, as many as thirty unlicensed signals can be heard, jammed between the commercial and non-commercial broadcasters in the FM band.
I am quite sure that other parts of the country have similar pirate problems. I do not see the FCC getting much more funding for enforcement purposes.
For most engineers, this will be a non-starter. Engineers (and other technical people) tend to see things in binary; on/off, right/wrong, black/white, legal/illegal, working/broken, etc. It is the nature of logic and dealing everyday operating status’ of technical equipment. A transmitter that is halfway working is broken. There is very little grey area in the interpretation of these things, nor is there very much human element. One cannot reason with a broken piece of equipment; it is to be either repaired or replaced.
Helping a person engaged in what is ostensibly an illegal activity, no matter how pragmatic such help might be, or how just or helpful the illegal activity may be to the community, would not be something that most radio engineers that I know would want to take part in.
Truth be told, some good might come from helping pirate broadcasters clean up their act. Over modulation, spurious emissions, poor quality transmitters all create bigger problems for everyone else. The moral dilemma is what type of help to offer and can this or any technical advice then be used to make bigger and better pirates.
I don’t know, but it may be time to start thinking about things like this…
Radio Shack (AKA, RadioShack, The Shack, Tandy Corporation, Realistic, Optimus, etc) appears to be filing for Bankruptcy if the Wall Street Journal and Reuters is to be believed. I see the words “private equity firm” in the article, that does not bode well.
Radio Shack of late has become a glorified cell phone store. It used to be one could get some emergency repair parts, an FM antenna or a CB radio as the need arose. As a young lad, it was fun to poke around and look at the various radio kits and other assorted fun things. My first shortwave radio was a kit from Radio Shack; assembly finished just in time to hear the Vatican Radio’s announcement that Pope Paul IV had died.
What happened to Radio Shack is fairly typical; what was once a niche market for hobbyists and experimenters tried to go main stream and lost their core customers. There are still plenty of electronics hobbyists out there, look at the Amateur Radio community as an example. Yet, that market was abandoned for the more lucrative general consumer electronics market. Unfortunately, Radio Shack never produced high quality stuff, so their reputation in the consumer electronics market was not that great. Thus, not being known for anything, they slowly slipped into irrelevance.
I found this interesting little video on Youtube recently:
That has to be a fairly high powered AM radio station to have that effect. According to the video, this is in Ukraine.
Other than generating RF burns to the hands, there is also the issue of exposure to non-ionizing radiation causing body tissue heating. Then there is the potential broadband RF interference from the arcing plant matter. This can cause interference to STL’s and other receivers.
Remember when there was actual competition between radio stations for the coveted #1 bragging rights? That was way back in the day when talented air persons were sought and compensated for their performances.
These days, when thinking about certain owners and their money men, a certain Fat Boy Slim album cover comes to mind:
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:
BNC connector pin improperly located
Looks like the pin is too far back in the connector. This is an old style BNC connector with a solder in center pin:
BNC connector solder type 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.
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.

~1st amendment to the United States Constitution
Any society that would give up a little liberty to gain a little security will deserve neither and lose both.
The individual has always had to struggle to keep from being overwhelmed by the tribe. To be your own man is hard business. If you try it, you will be lonely often, and sometimes frightened. But no price is too high to pay for the privilege of owning yourself.
Everyone has the right to freedom of opinion and expression; this right includes the freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers
~Universal Declaration Of Human Rights, Article 19
...radio was discovered, and not invented, and that these frequencies and principles were always in existence long before man was aware of them. Therefore, no one owns them. They are there as free as sunlight, which is a higher frequency form of the same energy.
