BIA/Kelsey: 2013 Radio Sales
Show Slight Industry Change
About the same number of radio stations switched hands in 2013 as in 2012,
making for a slow year for transactions,
according to BIA/Kelsey’s Media Access
Pro, a comprehensive data service and
analytical software that tracks the entire
radio industry. The largest transaction of
the year was the 53 stations sold by Cumulus Media to Townsquare Media in August,
estimated to be $238 million.
“The slight change in total sales of radio
stations in 2013 is evidenced by the few
number of large transactions,” said Mark
Fratrik, vice president of BIA/Kelsey. “This
year we anticipate a slight increase as the
economy gathers some strength.”
BIA/Kelsey tracks the value of transactions in radio and the number of radio
stations sold on a monthly and year-to-date
basis on its website.

bad Weather is an opportunity
for radio to shine
everal winter storms hit different parts of the nation during
January and February, and while it was only one piece of the
overall coverage, the weather that shut down Atlanta was all
over the news. Those who are used to ice and snow may have
gotten a chuckle from a city coming to a halt with what more northern cities would call a little ice, but the southern areas aren’t set up to handle such
weather. Regardless of whether or not proper preparation was made, the event
is yet another reminder of what radio does best: It’s an ideal public information network.
Staying with the Atlanta example, thousands of drivers were stuck in their cars on the road.
Children were kept at schools or in school buses on the road. Naturally, most of these people turned
to their cell phones to get information. But as often happens in an emergency, the cell networks
become overloaded. This is where radio’s one-to-many infrastructure stands out. Other cities had
similar difficulty with the weather, including Birmingham, AL.
News radio stations went into action to provide as much information as they could during the
situation. Even non-news stations carried news and information, with some dropping their regular
formats to deliver coverage. Other stations provided information as well, but they also offered some
companionship in various ways.
So once again, radio has shown that it can step up during a crisis. The general public—not just
regular listeners—knows it can turn on a radio and get information without buffering or network
People in cars of course had a radio available. Those in other vehicles or in buildings may not
have had a radio on hand, but they likely had their cell phones. This is where the on-board radio
tuner would be ideal. The on-board radio doesn’t use the network bandwidth and uses less battery
power. That’s a win all around.
And this information delivery doesn’t need to be limited to the audio channel. With data capabilities, weather maps and traffic data can be transmitted as well, again without needing the network
data capacity.
So even though radio had a chance to stand out again, the downside is that radio can’t just simply
become an emergency information channel while we wait for the next winter storm, flood, tornado,
earthquake or other major event. Radio continues to compete with other forms of entertainment
media that still pull listeners away from over-the-air channels.
It’s to radio’s benefit to remain top-of-mind with all consumers and not just die-hard listeners.
The effort to enable tuners in cell phones is part of the equation. Making HD Radio ubiquitous in all
receivers (for the data capacity and additional audio channels) is another step in the right direction.
But having the technology in place is one part. Radio stations have to provide programming that
will attract and keep listeners engaged all the time and not just during an emergency.

50 years or more — so why are we spending
all this money? Don’t they just stay up there?
As engineers, we read about tower failures and
many of have experienced it, either your own
or perhaps another station in the market.
The fact is that tower failures really don’t
happen that often. Electronics Research, Inc.

fine, or worse, risking a collision with an aircraft.
Perhaps the most overlooked parts of a
guyed tower are the anchor points. Even in a
correctly installed anchor system, the components are subject to some form of deterioration
primarily due to galvanic or electrolytic corrosion, which is a result of current flow in the
subsurface portions of the anchor system.
Recommendations for maintenance intervals for guyed and self-supporting structures are addressed in TIA/EIA 222-G. This
recommends that maintenance and condition
assessments are performed at a minimum
of every three years for guyed and every five
years for self-supporting structures. Further,
it recommends that inspections be performed
for all structures after a severe wind or ice
event. It also recommends these intervals be
shortened for structures in coastal areas or
for all Class 3 structures. Class 3 towers are
used primarily for essential communications
such as: civil or national defense; emergency,
rescue or disaster operations; military and
navigation facilities.
While a qualified professional should
perform maintenance, you can learn a lot
about the condition of your tower by simple
visual inspection (which is recommended to
be performed every year for guyed and every
three years for self-supporting structures). In
my opinion you should perform a visual assessment every time you visit the site, especially in
remotes areas that might be subject to attracting the attention of fun-loving locals.
I make it a habit to look at the tower from
a short distance to see if everything looks in
alignment. Of course the eye won’t catch small
variations, but once I noticed some sections of
the tower looked a little crooked, which turned
out to be a guy anchor that apparently was hit
by a vehicle. I also recently had an experience
with a guyed tower at a not-so-remote location,
that happened to be owned by a city, stood
next to its E911 call center and was used as a
primary microwave link to its other radio sites.
Someone unscrewed the turnbuckle on one
side and released a level of guy wires. Fortunately it was noticed and addressed before the
tower collapsed. You should also take note of
the condition of the paint and/or the operation
of the lighting system.
Circular AC-70/7460-1K.
> The integrity of a ground system should be
inspected and conductivity tests performed
annually. You can learn a lot about the performance and deterioration of a ground system
by noting the measurements each year. Try to
perform them around the same time of year. A
poorly functioning ground system can cause
deterioration of metals through possible galvanic or electrolytic corrosion.
A properly maintained tower can stand for
more than 50 years — that’s the best return on
investment you can have.

check every visit
When I arrive at a site I usually check to
see if the fence has been breached. It is very
common to see openings in the fence, which
usually means there is going to be — at the
very least — some copper, transmission lines
or AC compressor missing; but, it’s also not
unusual to find the doors open. While this
isn’t directly addressed in maintenance requirements, a broken ground ring will create
problems (and potential safety issues) and
should be repaired ASAP. You can also easily
check the anchors and foundations for unusual cracking, connections to the guy wires,
and rust or corrosion.
For a self-supporting tower, items that
seem to get overlooked are the bolts that connect the foundation to the tower legs. These
are typically bolted above and below the plate,
to allow for some minor adjustments to level
the tower base. Normally once the tower is
built, they pack the lower bolts with concrete
(between the base plate and foundation) to
protect them from moisture or water pooling.
I have seen many self-supporting towers with
these exposed and rusting.
None of this should take the place of a proper
full inspection of the tower, which includes:
> Climbing the structure and noting (and
hopefully correcting) loose bolts, documenting
bent members, rust, improperly attached line
and antennas, electrical connections to tower
lighting, missing grounds, improperly functioning safety items or anything else unusual.
They should take lots of pictures to document
the problems that should be included with a
comprehensive report.
> They should use a transit to determine the vertical alignment of the tower shaft and guy wires
> The tension of the guy wires should be measured and corrected if needed, every three years.
> The lighting system and tower paint
should be inspected annually per FAA

avoid advertising
Issue pitfalls
ecent advances in technology have
led to questions on the legality of
broadcast stations taking advertising from new sources. Specifically,
several states have now begun permitting online
gambling from authorized locations within
their state. Further, the popularity of e-cigarettes
raises issues as to whether the traditional prohibition on tobacco advertisements apply.
Online Gambling. Since the late 1990s, a
frequently asked question has been whether
broadcasters can take advertisements from online gambling companies. Initially, the best advice was for broadcasters to avoid taking these
advertisements due to the federal government’s
interpretation that online gambling violated the
Interstate Wire Act of 1961. In particular, the
Wire Act prohibits the interstate transmission
of bets and/or wagers on any sporting event or
contest, or a transmission in which the recipient is entitled to receive money or credit.
Because online gambling appeared to involve
the transmission of betting information, and
the bettor would either earn or lose credit or
money based on its success, questions arose
whether broadcasters would violate federal law
for providing information (i.e., advertisements)
regarding these illegal operations. In fact,
several broadcasters in the mid-2000s received
letters from the U.S. Department of Justice
seeking information on the advertisements, and
warning the broadcasters that future action may
be taken for aiding violators of the
Wire Act.
Flash forward to December 2011, when the
Department of Justice issued an opinion and
memorandum that offered a new interpretation
of the Wire Act’s applicability to online gambling.
Specifically, the DOJ opined that only interstate
wagering activity involving sporting events or
contests violates the Wire Act. The letter was
issued in response to states looking to permit
Internet-based lottery activity where state laws
permit such actions. The conclusion of the DOJ
was that such activities would not violate the Wire
Act, but that the states must take affirmative action to make it legal under state law.
For example, New Jersey recently joined
Nevada and Delaware to permit online gambling from locations within their respective
states. In these states, it would appear there are
no regulations that would prohibit a broadcast
station taking an advertisement from an Internet
gambling service operating in the respective
states. However, stations should look very closely
to determine if there are other regulations that
must be followed. For example, in New Jersey,
any gambling advertisement must contain a
disclaimer similar to “Gambling Problem? Call
1-800-Gambler.” Other states may have similar
requirements, so it is best to check with legal
counsel before taking advertisements, especially
if the station is unsure whether the state has legalized online gambling.
E-Cigarettes. The recent popularity of
e-cigarettes also raises advertising issues, since
there have been historical restrictions on advertisement of tobacco products. In particular,
broadcast stations have been prohibited
from advertising cigarettes and little cigars
for more than 40 years. More recently, there
have been restrictions on advertisement and
sponsorship opportunities by tobacco companies in connection with the FDA’s rules to limit
the exposure of cigarettes and other tobacco
products to children.
However, in June 2013, the Consumer
Protection Branch of the Department of Justice
issued an opinion letter ruling that e-cigarettes
do not fall under the restrictions on advertising for cigarettes because e-cigarettes do not
contain “rolls of tobacco.” On the other hand,
the U.S. Court of Appeals had ruled in 2010
that the FDA should regulate them as tobacco
products and not as medical devices.
As a result, it would appear that broadcasters could advertise e-cigarettes, since they do
not appear to be covered by the decades-long
ban on cigarette advertising. However, broadcasters should ensure that the advertisements
do not contain false or misleading information that would be difficult for the consumer
to verify. The FTC has warned that misleading
advertisements (“none of the harmful ingredients of tobacco cigarettes”) will likely draw
close scrutiny by the FTC. Moreover, states or
local governments may also have regulations
that prohibit advertising e-cigarettes.
In summary, technological changes may
be opening new advertising opportunities.
However, the best advice for a broadcaster is
to consult with legal counsel before taking the
advertisement to ensure they do not run afoul
of federal, state or local regulations.

First, let’s make the assumption that you already have a spot for the
new building, and at this spot there is nothing but a patch of ground. It’s
a blank slate. Step one would be to make a list of requirements for the
proposed structure:
> What will the building contain?
> What are the contents’ electrical requirements?
> How much heat do the contents generate?
> What will the physical environment be like?
> Will the structure be designed for future expansion of contents?

Oversee construction
Personally make punch list
To answer the first three questions
you will clearly need to have a plan for
your transmitter facility—probably a
block-diagram (at minimum). Using
a spreadsheet then you can easily list
the space requirements, the electrical
requirements, and heat generated by all
of the proposed equipment.
What about the physical environment? By this I mean will the site
be on a mountaintop in the desert, or in a more temperate climate (like
northern California) or maybe even Alaska? The structure may have
special requirements based on where it is to be located.
Perhaps the most difficult question to answer is the one on future
expansion. You may only need 10’ by 10’ of floor space to accommodate
your needs, but what about the possibility of future tenants, or your own
F e b r u a r y 2 0 1 4 | r a dioma gon lin e .c om
expansion? Think about it: if the site is good enough to develop for one tenant (you) then isn’t it quite likely someone else will also want to make use
of it later on? In the future, expansion is always going to be more expensive
(because things don’t get cheaper as time moves on) so the time to invest in
extra space is really at the outset of the design and construction.
Stick-built or pre-fab?
Once you have answered these questions, the next is whether or not
to go with a stick-built structure (that is, built on-site) or with a prefabricated building.
Stick-built is going to appeal to some because there is a greater deal
of control over the final result. The design can be custom; and as the customer you can be right there at the offices of the architect to provide all
your input on how the building should be designed, and what it will look
like. You can drop in to the offices of the MEP (mechanical, electrical, and
plumbing) engineer to look over his shoulder to make sure all the electrical design is correct. You can go right to the construction site every day to
visit your general contractor, adding your input on how well the process is
going. His (or her) stress can become yours! And finally, you can be right
there to make out the punch list yourself.
As you can probably tell, I’m not inclined to go with the stick-built
route for a new transmitter building. If you still need to be convinced that
a modular, prefabricated building is the better option, then let me add
a few more points to do my best to change your mind.
Modular (or prefabricated) buildings are structures that are
manufactured in a facility, and eventually delivered to the customer site. The manufacturing facilities are enclosed facilities,
and that prevents environmental factors from delaying the
construction. Additionally, construction materials are
delivered to the facility location, where they are safely
and securely stored, preventing damage from the
elements and potentially even vandalism or theft.
Modular buildings are designed to the same
codes and standards as stick-built facilities
but are generally stronger than conventional structures because they need to
be able to withstand the rigors of
transportation and craning on to
the foundation upon delivery.
The same materials
are used: wood, steel,
But those factors aside, let’s
look more closely the project
elements, comparing stick-built
to pre-fabrication.
Design. One of the few advantages to stick-built previously
mentioned is that you, as the
customer, will have a higher
Pre-fab Advantages
> No environmental delays
> No damage from elements or
vandals during contruction
> Same codes/standards, but
generally stronger
> Cost effective
> Speedy timeline
> Conserve your energy

degree of control of the final result if you go with a custom project. On the
other hand, you will be paying an architect for a “one-off ” design. The cost of
the design is spread out over many projects in the case of modular construction, providing an obvious cost advantage. The same goes for the MEP design;
there will be some customization for the electrical design, but that will be
cheaper than hiring an independent engineer for a one-off.
Building foundation. Your construction time-line can be accelerated somewhat because the foundation can go in while the pre-fab building is being
made; no need to wait for the foundation to be finished before construction
begins on the building itself. At least one of the modular building manufacturers claims that the schedule can be 30 to 50 percent shorter than that of a
stick-built project.
There are a couple of options as far as foundations go for modular buildings. A slab foundation, which is a large concrete pad, is one. The slab layer
construction consists of sand or gravel, at the bottom of the pad. Over that is
placed a vapor barrier, which is a thin layer of impermeable material (typically
polyethylene sheets) used to isolate the concrete from the damp ground. On
top of that goes a wire mesh, and then the concrete. The edges of the concrete
are then covered with an insulating material.
Another option is the crawlspace foundation; the modular building is
placed on piers and therefore permanently raised above ground level. This is
certainly a good option if you plan to build in any area that potentially floods.
In either case, in the permitting process you will need to adhere to local
building codes and regulations; it’s outside the scope of this article but suffice it
to say that stick-built buildings will require permitting and adherence to local
rules as well.
Mobilization expense. I think it is safe to say that the construction of a
given size structure, inside of a factory, is going to use less man-hours than the

equivalent structure at a remote transmitter site (especially a mountain top). There are many possibilities for construction delays at a remote transmitter site. In either case a foundation is going to be necessary, but in the case of the modular building, fewer trips to the site will be required after the foundation
is ready.
One of the last steps in a project like this will be the delivery of the modular structure to its intended
home. In most cases the structure (or structures) will be delivered by way of a truck and flatbed trailer
combo. A crane is used onsite to pick the structure from the flatbed and to set it on the foundation.

Knowing that the delivery might very well be difficult (especially
to a mountain top) it’s wise to study the necessary route and to keep
these items in mind:
> Inspect the delivery route for obstructions. Look for 15’ of height
(minimum) under all obstructions along the way. Of special concern
are bridges, power lines, and tree branches.
> Check for steep grades along the way. A gradient in excess of 5
percent (1 foot in height gained along 20 feet horizontally) could add
costs to the delivery.
> The pathway should be
at least 20’ wide all the way
along the route.

that delivery and craning of
a modular building is even going to be possible (and not excessively
expensive) at chosen site.
Aside from those activities, you need to consider your own
as well: While taking care of all the day-to-day things that the
typical broadcast engineer takes care of, the last thing you want is
F e b r u a r y 2 0 1 4 | r a dioma gon lin e .c om
Probably one of the most well known providers of modular type buildings is Thermo Bond. Thermo bond equipment shelters are constructed
to customer’s specifications and shipped fully assembled, including lights,
outlets, air conditioners, heaters, generators, transfer panels, ventilation
systems, cable ladder, and grounding systems. Shelters are available in
sizes ranging from 4’ width x 6’ length to 24’ width by 42’ length.
Fibrebond provides pre-fabricated structures with 5,000 PSI concrete
walls. Its standard design provides 100 PSF roof live-load capacity, 150
PSF floor load (with perimeter foundation) and 500 PSF floor capacity with
a slab foundation, in addition to 150 mph wind load (for exposure D, which
applies to flat, unobstructed areas and water surfaces outside hurricaneprone regions).
Enviro Buildings interestingly says its shelters can be shipped pre-assembled or in a knock-down, panelized configuration. The modular shelters
can be transported by all-terrain vehicle, helicopter or up freight elevators. It
also claims that “assembly is so easy a two-man team can easily install an
enviro building shelter.”
Mobile Modular says one of the additional benefits to its concrete
construction is that its buildings have a bullet resistance; a 30:06 won’t go
through the wall at point-blank range. Concrete construction resists all boring insects, such as termites; and lastly, concrete construction resists mold
and mildew, which would certainly extend the lifetime of the structure at a
mountaintop or a flood plain.
to add visits to an architect and/or MEP engineer’s
office. Perhaps more importantly, you will probably want to avoid extra trips to the remote site
to make sure your general contractor is on-track.
The modular type of building provides an advantage to you here—not as much of your time will be
required to get the results you expect.
If you simply consider all the telecom sites that are
relatively new (especially cell telephone sites) it’s clear
that the large telecom providers see the benefits of
modular construction. Choosing between stick-built
and modular would seem to be fairly straight forward,
but clearly there are going to be instances where it just
won’t work. You must do your research carefully, as
the results, good or bad, will last for years to come.

Rack-Room Wiring:
by Doug Irwin
Spoke-and-Hub vs. Point-to-Point
Block 1
have been involved with several
large studio construction projects
that were designed and built with
the spoke-and-hub philosophy,
and I’ve inherited rack rooms (and studios)
that were wired on a point-to-point basis. My
experience is that the point-to-point method is
inferior in almost every way.
You could make the case that the pointto-point method is superior in one way—it’s
quicker initially. I know there are instances
in which you (the designer and builder) find
yourself up against an exceedingly short time
line for a build project—and there may not be
time or budget to do it right (in other words,
the spoke-and-hub way). You slap stuff in a
rack and connect the dots with wire. When
finished you stand back and say, “Voila.”
Now, there is plenty I hate about this. Firstly,
when a wire is put in from equipment A to
equipment B and they are in different racks, you
can bet that before long, you’ll need to move
item A or item B, and of course the cable won’t
be long enough then. So, for the second time,
you’re installing a cable. Oh, and don’t forget to
remove the old one, right? Is it in a bundle? Have
to do wire management all over again?
Secondly, I don’t think that the point-to-point
method lends itself to documentation well. You
can label them in a serial fashion; but when old
KeeP IT aT Bay
This may seem a little too old-school for some, but in
the rack itself, I still like to use patchbays (even for aeS,
with the appropriate type of patchbay). This facilitates
testing and emergency response. even the least technical person can usually be talked through inserting a
patch cord when it’s needed.

wires come out, do you
re-assign the old number
to a new cable, or simply
retire that number? If you
re-use old numbers, better
make sure that any and all
old versions of wire-lists
are found and deleted.
So let’s talk now about
the spoke-and-hub
method. Each rack in your
rack room will have an
associated punch-block
or some type of terminating method. One or more
punch-blocks will placed in
Rack 1
the rack at some unobtrusive point. I put those
in the back of the rack (yes—you must have rear
rack rails) at a height that is convenient for use of
the punch tool. Too low is hard on your back and
knees; too high means you’ll be using a ladder all
the time. In the rack room will be a backboard
upon which are also installed the same type of
punch-blocks. Trunk cables are then installed
between the punch-block on the backboard, and
its complement in the back of the rack.
Now, inside the rack itself, everything is connected by way of the punch-block; and to connect
equipment A to equipment B (if they are in different racks) you’ll make a cross-connect between
the associated punch-blocks on the backboard.
So now what are the advantages to this obviously slower method? Well, they’re many-fold.
When it’s time to move equipment A or equipment B, instead of running yet another cable
between racks overhead in a cable tray or under
the floor, you will instead just put in a new
cross-connect, conveniently, on the backboard.
And, when installing new equipment in the
rack, instead of having to run cables up and out
wherever, now you’ll make a connection inside
of the rack, to the block; and on the backboard,
Block n
Rack 2
Rack 3
Rack n
you’ll add a cross-connect. The time you invest
in doing it this way will pay you back with time
savings, over and over and over again during
the life of the rack room.
Documentation using this method makes a lot
more sense in my opinion. Instead of just labeling
the cables in a serial fashion (1, 2, 3…n) I refer to
the punch-block in the documentation because
they don’t change. In other words: a cable starts
off at (as an example) block 1, column 1, pair 1.
If you use a spreadsheet program such as excel to
keep track of these, it’s simple also to put hyperlinks in so that you can bounce over to the document for the other end of the cable in question.
As far as the types of blocks, there are not
that many choices. Stay way away from 66
blocks. I like the ADC QPC style of punch
blocks myself, mainly because of their capacity
for multiple wire punches on the same posts;
but, Krone makes great blocks as well. These
are nice because you can insert a shoe in to
each pair of connectors to facilitate testing.

Built-in stereo mic
pocketrak pr7
Up to 24-bit/96kHz
Records in
linear PCM
and MP3
By Gil T. Wilson
igital recorders can be quite a specialized piece of equipment. Many
recorders are inexpensive and do
nothing but record voice and allow
for playback. Some require playback through a
line out and the upload to computer for further
editing is done in real time. Some provide a USB
port to access the internal memory while others
provide a slot for a memory card.
If storage and playback are your only specifications for purchasing a digital recorder, the
Yamaha Pocketrak PR7 handles that, but it can
do much more. The PR7 has 2GB of built-in
memory so you can start recording right out of
the box. The storage doesn’t stop there; there is
also a micro SD/SDHC card slot for up to 32GB
of storage allowing you to record approximately
50 hours of linear audio at 16-bit/44.1kHz. That
should be plenty of space for the news reporter
and field recorder. It’s also great for recording
impromptu podcasts or station events. Using
only a single AA battery, the PR7 can support
continuous recording for approximately 44
hours at MP3 and up to 29.5 hours using the
PCM 16-bit/44.1kHz format.
The PR7 has both a USB out and a headphone out. The USB connection is perfect for
quick link-up to a computer for uploading
tracks and even importing tracks to the PR7.
With PCM stereo WAV or MP3 file formats
available, the recordings are usable by all
major audio editing software. The headphone
out also doubles as a line out when needed.
The PR7 even has a small built-in speaker for
immediate listening to recorded files.
Let’s move on to the input side of the action. This is where the specialization of this
starts to
come in.
F e b r u a r y 2 0 1 4 | r a dioma gon lin e .c om
Capturing audio
The main aspect of the input side of
this digital recorder is the stereo X-Y
microphone, which is mounted on
the top of the recorder. One of the fun
things I do when testing stereo recorders is to place the device in the center
of some sort of turntable with the mics
perpendicular to the surface and press
record. This provides an interesting test
of the stereo capability. Listening to the
recording I nearly got a sense of vertigo
from the effect. The directional mics
work well on the PR7.
The other input of the PR 7 is a
3.5mm line/mic in connector. If you have
a favorite handheld mic you can still use
it and keep the appearance of the reporter on the
street. I plugged in my trusty 58-like clone and
the resulting recording was fabulous.
Use the menu to select between mic
and line input levels. While recording, the
firmware within the PR7 allows for automatic
sound divide. While I didn’t use this feature, I
think it would be an easy way to convert some
of my vinyl and cassette tapes to digital (yes, I
still have those).
All the above features would alone make
this a desirable unit for most radio professionals, whether for news reporting or
production, but this unit starts to get a little
more specialized for the musician seeking a
lightweight (approx. 3oz) recording unit. The
unit also has a tuner and a metronome. The
metronome will play through the headphones but is not recorded onto the track for
practice or laying down tracks.
What I found interesting was overdub
feature. At first I didn’t think I would use this
feature, but the creative director in me started
and varispeed
Operates on
a AA battery
to come out. I found I could lay down tracks
and then using the overdub and leaving enough
space do an on-the-fly two-voice (or more)
rough spot. I may actually use this to make a
spec spot when I’m out of the studio. For grins
I tested to see how many overdubs I could create. I got to 24 overdubs before the chaos was
just too much. And since it’s all-digital, there
was no signal loss.
The Yamaha Pocketrak PR7 also comes
with a free download of WaveLab LE software,
which provides two-track audio editing with
professional EQ and dynamics processing for
mastering or enhancing your tracks. You can
even upload your audio files to the web using
the dedicated podcasting function. So if you
don’t have the full editing software available
this can be used to tweak your recordings using this recorder.

Handheld Testers
by Chriss Scherer, editor
hen setting up a remote, in-house
performance, or any other event where
you need to run cables, there’s often little time to waste on a bad connection.
But rather than run all the leads and try a trial-by-fire
test, take a few minutes and check the cables before
they are packed and loaded. And to really simplify
those tests, get a handheld and very portable tester.
The ability of testers range from very basic
continuity tests with a few connectors, to
impedance measurements, signal generation,
and even more advanced functions. Consider the
options you will really use to select the right one
for your tool kit.
We found several models that offer a variety
of test functions to help troubleshoot cables and
installations without breaking the bank. Most of
these testers go far beyond XLR connectors for mic
cables. USB, Ethernet and many other connector options are common—and so are the assorted
tests that can be made. Various types of test signals
at varying levels are often available as well. They
all operate on batteries, so use in the field is no
problem. And the current draw is so small, a set of
batteries will last a very long time.
The operation of many testers is usually very
simple, so even non-technical staff can diagnose a
problem when needed, perhaps saving an engineer
some frustration.

Firmware update | Nautel
NV 4.0, NX 4.01: A key element to the update
for both product lines is new test functionality,
which allows real-time measurement of MER
(Modulation Error Ratio). The measurements
follow the new NRSC FM standard and do not
require external equipment. MER metering
is accessible from the Nautel Advanced User
Interface (AUI) Constellation View display and
may be viewed from the front panel 17” LCD
touchscreen or via the Internet. Other updates
addressed in the new firmware for both series
include an updated Flash player; SMTP login
capability for e-mail; port forwarding support;
NTP (Network Time Protocol); the ability to
save meters and critical parameters in memory;
the ability to take action on audio loss in a manner similar to other Nautel products; restructured preset and sub-menu structures; SNMP
(Simple Network Management Protocol) traps;
summary alarms for remote interfacing and remote AUI timeout. NV-specific updates include
PA field bias of individual stage amplifiers; a
composite power limiter, left and right limiter;
Asymmetrical HD Sideband support, HD PowerBoost support via presets and RF turn on delay
for generator operation. NX-specific updates
include a multi phase PDM cancellation routine,
which results in an improved RF spectrum; a redesigned scheduler; USB audio (requires Nautel
USB sound card) and playlist controller and
Icecast/Shoutcast capability (Nautel USB sound
card required).

That Was Then
by Chriss Scherer, editor
n Jan. 7, 2004, ESPN Deportes launched as the
Spanish-language outlet for ESPN sports fans in
the United States. To commemorate the milestone, ESPN Deportes celebrated with a special
production of more than 12 hours of live programming and
content from Miami Beach, FL, on Jan. 7.
The celebration in Miami included special content from
Adriana Monsalve, David Fiatelson, Jorge Ramos, Rosana
Franco and others.
In January of 2004, ESPN Deportes went on-air with
Somos ESPN Deportes, a show that previewed key programming and featured an array of Latino sports stars.
The special introduction was followed by the inaugural
Spanish edition of SportsCenter and a live telecast of the
NBA game between the Golden State Warriors and the
Dallas Mavericks.
Launched a year after ESPN Deportes television, the
radio network has grown from a handful of affiliates to a
network reaching more than one million listeners every
month with 47 affiliates across the country, covering 80
percent of the U.S. Hispanic market. The radio network
currently covers more than 300 live sports events scheduled every year.
This Month in
SBE History
2014 Marks the 50th Year of the Society
The Society of Broadcast Engineers was founded with a humble purpose:
To serve the interests of the regular station engineer. As the society grew and
evolved, it became much more than a loose affiliation of interested engineers. As an organization grows, it requires governance and structure. Such
was the case with the SBE, and at the February 1967 meeting of the SBE
Executive Committee, led by second SBE President Charlie Hallinan, the
plan to incorporate the society began.
As part of the incorporation process, the organization needed to draft a
constitution and by-laws. With the concurrence of SBE board members Leo
Reetz, Ben Wolfe, Bill Kelly and Joe Risse, the two documents were accepted
and the incorporation papers for the SBE were filed.
Also at the February 1967 meeting, Joe Risse was appointed the editor of
the SBE Journal, replacing John Battison.
