Radio Tech A Part of the Community
Radio stations often do Public Service Announcements, to publicize local events and social groups - even sponsoring some of all of an event. On the other hand, it is not too common for an engineer to do. But during October, Santa Paula CA engineer Richard Rudman has sponsored a wheelbarrow in the local Rotary Club Pumpkin Patch event. His sign was especially timely, given the PG&E power outages this month!
We are still looking got a picture of Richard pushing the wheelbarrow!
Don't You Wish?
If you have ever been given a new studio site to build, without anyone thinking about the need to STL links, you have had one of those "bad" days. Since many of them have only the slightest clue as to where the transmitter is, much less how it all works, the only solution may require two or three hops of RF, plus another link.
Occasionally you work hard and find a solution: locate a nice site with a clean STL shot ... and then foliage grows up in the aperture - even a new building! Now what?
Some have given up and just run an Internet STL, but others fight for other solutions - a different studio site, a link via another tower in the cluster, etc. Others go to daydreaming how to solve the problem. Don't you wish? Sometimes?

When the Wind is Really Strong
This picture comes from the SW, where a wind storm apparently came over the parapet and sheared off the pole holding a DB224 antenna. You can see the bottom element still on the pole, and the rest laying on the roof. The curious part is that the shear area does not look bent - just sheared off. Must have been some wind!

Staying Alert as Flu Season Runs
Brian Brashier of KCNP, Chickasaw Community Radio in Ada, OK, shares this picture to remind us that Flu Season continues, and keeping everyone safe and healthy takes proactive efforts.
While you should definitely be sure (by testing and checking) that you are using a non-destructive method, knocking down germs is a smart move.
Some more prophylactic ideas are located here.
Radio Station Up A Tree
Perhaps it was a zoning issue, perhaps it was trying to avoid the cost of a traditional tower, perhaps it was another reason, but this picture, shared by Clay Freinwald, is of an LPFM station in the Seattle market.
In any event, we are looking at a 2-Bay LPFM antenna hung high, about 100 feet up, in a tree. The antenna itself is visible, although you do have to look for it.
At the base, the antenna is fed by a transmitter at a church.
Putting a Cord to Good Use?
There is hardly a single broadcast shop that does not have a pile of AC cords under the bench. Over time, the pile of cords grows, waiting for some reason to be used. And, here it is, seen by Dave Dunsmoor on a windy night in the upper mid-West:
All we can say is ... it worked. The door stayed shut!
Curious PC Boards
It is tempting for any engineer to put a little "Easter Egg" on his PC boards. Sometimes it is his initials, sometimes a logo. Here is one that went the extra mile. If you have ever been to England, this PCB will look familiar:
Yes, it is a map of the
London Underground! Even neater - it is a working circuit of a radio
Do you have - or know of - and interesting PC Boards and their contents? Please share!
Hurricane Matthew Leaves Mark
Early October 2016 featured Hurricane Matthew - a strong, slow moving hurricane - that wrecked havoc from Florida to North Carolina and more as it hugged the East Coast, eventually coming ashore, but mostly flooding huge areas, killing electrical grids, and stimulating a lot of evacuations. At least 18 stations were knocked off the air during the storm.
Broadcasters felt it too, as evidenced by this picture of WZKT in Goldsboro, NC.
Allen Sherrill reports two of his three sites in Eastern North Carolina were flooded, with this station likely to dark for a while.
How did things go at your facility?
After all, they do say imitation is the sincerest form of flattery.
With that in mind, we have to give a lot of credit to John Antonuk, Broadcast Transmission Engineer for iHeart Radio in Fairbanks, AK.
Taking a cue from an earlier BDR logo, which featured your Editor inside a Continental 317 transmitter at KOMO on Vashon Island, Antonuk promptly secured a spot inside KOMO's standby RCA BTA-50F transmitter.
OF course, one of the little secrets that
younger engineers may not know is that the transmitters of the 40s
and 50s had plenty of room to walk around inside ... although
probably not while the HV was on!
Clay Freinwald tells us "I’m used to contractors posting some caution signs that are required by regulators. In this case, the contractor did not just post a sign – He erected a banner to cover all the bases! Frankly I found this moderately funny.
NAB Breaks Ground on New Headquarters
(June 20, 2016) 1 M
Street SE is the site, just a mile from Capitol Hill, where the NAB
is planning to set up their new Headquarters. The new 10-story
130,000 square foot building is planned for completion in Fall 2018,
along with a 13-story residential building. Interesting features
include a rooftop terrace, a conference center on the top two
floors, and a 100 seat theater. The NAB has been at 1771 N Street NW
for the past 96 years.
A Hot Time At The RF Output
(May, 2016) Sometimes things happen inside the transmitter or the RF plumbing that can go unseen for a while, and then - oh boy! the alarms go off. Paul Easter was kind enough to share the results after apparently some "crud built up on the teflon insulator until it started to arc." This might be a reminder to look "just a bit further" when cleaning a transmitter and/or using an IR Thermometer to check the entire RF chain.
Studio Techniques of the Now Distant Past
(January, 2016) For an interesting look at what radio was like in its first four decades, get one of the text books used in schools and colleges to teach young folks the business. It is hard to forget lines from those late 1960s textbooks noting that, in control rooms, "Two tables equipped with 33 1/3 and 78 r.p.m. speed settings are necessary. A 45 r.p.m. setting can also be useful at times." (italics are mine.)
Do you have a favorite quote from your school broadcast textbook? Mine, another one regarding studio operation I will never forget, is: "If the needle is slammed abruptly to the top of the dial, the action is called bending the needle." (emphasis from original text.)
I can only say that when Burt Weiner shared this picture, memories flooded back, and I almost lost the drink in my hand.
(Yes, this is not an audio meter. But the concept works, right? Sometimes, to tell a story, you need to bend things a bit!)
The 2016 Midwest Floods
(December 30, 2015) When bad weather hits, it is often a challenge to get to the studio, much less the transmitter site. December rains especially hit the area around St. Louis, MO. Gary Glaenzer shows the effects of too much water faced by local responders.
To give you a small view of what was going on, Gary sent these pictures of a site on I-44 and MO-141, about a half-mile from the Meramec River. What is a bit frightening is how fast flooding can affect lower lying areas. The first two pictures are from the same site, showing what happened over one night with 6 to 12 inches of rain falling!
As is obvious, no one this this
area is going anywhere.
The Toy Store Meets Broadcasting
(November 16, 2015) It is always interesting when someone shares a great picture (or pictures) with us. Some, as you can see, come from disasters, others from interesting sights and/or signs on the street, still others just interesting. This picture came from Jim Weinberg of North Beach Media in southern Florida. He has been collecting toys with a broadcast - especially TV - theme for 40 years.
cannot really do justice to the collection, so we are going to do.
Perhaps, if you would like a better look, here is the original picture in full resolution. If you have some similar toys or promotional items - radio or TV - please share them here. And, if you'd like to chat with Jim about his collection, send him an email!
KOKC Meets the Tornado
(March 26, 2015) It was only a
short time ago
that the worst thing going was snow, so it was a bit odd to hear
about tornados. Sure enough,
Moore, OK got
hit again. There are a lot of power line flashes. And a death.
KOKC in Moore, OK, got hammered by the tornado. At first it looked like Tornado 2.5, KOKC 0.5. Chief Engineer Mike Fields noted: "It is so sad to see those Blaw Knox towers on the ground. Nearly 70 years they threw their finger up a mother nature and yesterday she won."
But Fields then added that the win was temporary: "We'll be back on the air by the weekend. The big cranes are rolling in tonight and tomorrow. We should have the top section separated by tomorrow. Then we'll sweep it, get the new network built and be back on at 10-20 kw day."
KOKC did get back up - in less than 24 hours. Station Engineer Fields and DOE Randy Mullinax managed to use the remnants of the last partial tower and got back on the air. But they reported the tower was unstable, so the plan is to install a temporary tower on base 1, and then rebiuld all three towers, with a new system design.
We certainly hope KOKC gets back to full power on all three towers quickly.
April 10 - Earlier this week, KOKC took down the stub, because they needed the insualtor for the temporary 190-foot tower (200 Ohms, more or less). The station returned 5:30 PM, Thursday.
Snow, Ice, Wind = Trouble
Joel Epley had the unhappy task of hiking up the mountain when his station WMDR-FM, Oakland, ME went off the air. It is never fun racing up a mountain in the snow, but then being greeted by this might be just a bit discouraging:
The 200-foot tower appears to have had a guy wire or two break under the snow, ice, and winds. (The ice load was as much as four inches on nearby towers.) The tower, as you can see bent and landed upon the transmitter shack roof. Complete repair may take until Spring, when 4x4's can again access the site.
Thanks to Joel for sharing his pictures.

Yes, we can see the fine print shows us this is not the FCC we all know and love. But, for a moment, might you might be tempted just a but, especially if you have just filed an application in DC and wanted it to be blessed?
Taking the Mug to New Heights
6/15/13 - The coffee mugs that we passed out a few years ago were so popular that a request was made to do some portable mugs this year. So that is what we did.
Richard Rudman decided to take the mug to new heights, on top of a 40-foot Genie lift.
A lot more MugShots are on https://www.thebdr.net/articles/mugshots.html See who are the coffee adicts!
Sliding Around the Rules
... Slide Rules,
The BDR gets a taste of winter weather
2/20/13 - OK, so a half an inch of snow is no big deal to you, we understand that. But when it snows in Tucson, it is pretty crazy in a place where we run around in short sleeved shirts almost all year long. So, indulge us just a bit for feeling like we had a major storm. After all, they postponed the golf tournament a whole day because of this white stuff!
Virtually no one in this town knows how to drive in the snow. At the height of the storm, visibility was almost nothing. Fortunately, except in the foothills, the snow did not accumulate on the streets. Still, for a once in a decade or two, it stayed on lawns (rock gardens out here!) over night.
All right ... go
ahead, you guys from other parts, where you are dealing with a lot
more of this stuff.
Radiotelephone First Class
Remember the First Phone? Recently, while going through old files, Margie Wrye-Clement found her father's first First Phone, dated 1937. This is just three years after the FCC was created!
You may click to enlarge!
The real oldtimers will recall that in those days, you had to your "service record" signed when you left a position. A few unscrupulous operators tried to "jam" an engineer with a bad endorsement, but most of the time, it was an interesting record of service.
[September 10, 2011] The remnants of Hurricane Irene have brought flooding and other problems all up and down the East Coast. News reports have shown flooding in many cities. Of course, some radio stations just go off the air when the power dies, or the water comes. Some that stay on merely keep the automation going, to the commercials will play.
When the power went out, WEBO got the generator going. When their studios in downtown Owego were flooded, WEBO did not stop broadcasting - nor turn on the automation to cover the hours.
Instead, they borrowed
a camper and took it to higher ground at their AM transmitter site,
where they set up and have been broadcasting for days, gathering
information and telling the community what they need to know. Most
of the broadcast gear was saved from the studios, except for the
UPSs and computers that sat on the floor.
As seen above, staff and guests crowded into the camper and kept up the information flow.
It was no accident that owner Dave Radigan and his family were awarded the "Small Business of the Year Award" in January 2009. Their bottom line is the community.
By the way, the downtown studio has significant water damage. So, the station will be in the camper for a while ...
A Unique Product

Revisiting Memphis after the Flood
WDIA, Memphis, TN
As with all floods, eventually the water recedes. Then starts the process of cleaning up and getting transmitters back on the air. The following information and pictures were supplied by the kind folks at WDIA as they show some of the the aftermath of the flooding - and why it is important to do a full inspection of the entire transmission system at any station before powering back up.
One of the things that might surprise you, for example, is to know that the insulators that were contacted by the water did not fare so well. For example, in this picture at tower 1, every insulator that was touched by water shattered!
That came from only three inches of water (see below for the picture when the water crested). And was attributed to water getting past the glazing and into the interior of the standoffs. With more water, the effects were more dramatic.
Now, here is a look into another ATU - one that was under six feet of water.
Here is a look back at the flooding that reached its peak in early May:
WDIA Tower 1 on 5/5/11.
No, it is not shunt fed.
