Random Radio Thoughts
Cris Alexander, CPBE, AMD
Crawford Broadcasting Company
Now we know… well, sort of.
Last month, I was bemoaning the fact that it had been over sixty days since
the FCC commissioners voted to approve new rules for terrestrial digital
radio and at that time we still had no report and order. Right after writing
that, the R&O was released. There were few surprises in the release;
it contained everything we were expecting and maybe a thing or two we weren’t.
Two things in the R&O that will require some doing on the part of digital
broadcasters have to do with station ID and public file. Each stream must
be separately identified at the top of the hour, and some indication must
be provided that tells the listener that he is listening to a digital stream.
The FCC indicated that the normal text display on HD Radio receivers would
take care of the latter requirement. As for the public file, the FCC says
that the same “public interest” requirements that apply to the
analog station also apply to the digital (multicast) signals. Our communications
counsel advises that this means we must provide public interest programming
and a separate issues/programs list for the public file. We have all already
been in compliance with multicast EAS requirements; interim rules on that
went into effect last December. None of this really impacts FM stations without
multicasts or AM stations.
AM nighttime digital was the one thing many of us were waiting on, and
that was in the R&O. Now we get to wait again, this time for publication
of the R&O summary in the Federal Register. The rules will become effective,
I’m told, 30 days after such publication. No word yet on when that will
Six weeks later…
Last month, I mentioned the Santa Catalina Island fire and its effect on
our Los Angeles station, KBRT. Now more than six weeks after the fire, KBRT
is still operating on generator power and using our Ku-band satellite link
for an STL. Edison has restored power to the site, but they could not “legally” give
us the same three-wire delta configuration that the site has used since 1952.
That has required us to reconfigure the site wiring and service entrance,
not an easy task on a desert island. So while the local electrician works
on our problem along with all the other jobs he has going, our chief engineer
continues to schlep diesel up the hill in five-gallon cans, 20 gallons (and
$100) a day (diesel is $5.00/gallon on the island – think about that
the next time you feel like griping about $3.20/gallon gas along the Front
LED Marker Lights
Have any of you tried LED obstruction lights on your towers yet? Crawford
has installed them on several of its Front Range area towers of late and so
far, so good. We are using Dialight L810 fixtures, which are 120-volt direct
replacements for a standard marker fixture. They screw right onto a 1-inch
conduit (they are supplied with a 1-inch to _-inch reducer, so they’ll
also screw onto a _-inch conduit). Just connect the hot, neutral and ground
wires to the existing wiring and you’re good to go. The GRB crew has
made short work of the replacements to date, reporting no issues.
We’ve been paying about $275 each for these. Every time we lose a marker
lamp on a tower, we replace all the marker light fixtures on the tower with
LED fixtures. Since most of the cost of replacing a tower lamp is in the labor,
it makes sense to use the labor cost that would go to the relamp and use it
for a one-time (within the five-plus year lifespan of the LED fixture) replacement.
Next year, we plan to replace all our beacons with LED fixtures. Those are
a bit pricier, but should pay for themselves quickly in reduced utility and
relamping labor/bulb costs. Dialight has a beacon retrofit kit wherein the
top half of the existing code beacon is replaced with an LED beacon fixture.
The bottom half of the beacon is used as a junction box for the wiring.
The one thing we’ve got to figure out how to deal with is monitoring.
With the LED fixtures consuming less than 10% of the power of conventional
incandescent lamps, current sampling isn’t so easy. Hopefully, SSAC
will soon come out with an LED tower light monitoring module.
Radio Technical Programs
I have heard from quite a number of Front Range radio engineers in recent
months with the message that they want radio-specific technical programs at
Chapter 48 meetings. In response, I have asked a number of industry people
if they would be interested in coming to make technical presentations. Not
surprisingly, the response has been enthusiastic. I have several commitments,
all of which will undoubtedly involve very interesting presentations, and
I expect many more. We should be able to fill the calendar.
As fall approaches, I will let you know the dates, locations and times
for these presentations. If you have any specific requests, drop me a note
and I’ll see if I can line something up. The best technical programs
are those that address real-world problems or deal with the real-world issues
that we face every day.
We very much look forward to seeing all of you at the annual Lookout Mountain
picnic on the 13th!

AMATEUR RADIO NEWS
Compiled By Tom Weeden, WJ9H
From Chapter 24 - Madison
Field Day 2007
Amateur Radio’s biggest operating event of the year, Field Day, was
held June 23-24 this year. While Field Day’s focus is on setting up
temporary portable stations operating on emergency power, stay-at-homes and
mobiles also participate. Since 2003, there has been a special category for
stations operating from established Emergency Operations Centers.
Cell phones are ubiquitous these days, and it’s natural to rely on them —but
what happens when they don’t work? As the world becomes ever more dependent
on complex telecommunications systems to cope with daily life, the goal of
Field Day is to show that hams can communicate with one another, no matter
what, without the need for any infrastructure. This is a capability that tends
to be taken for granted, but that is increasingly rare — and increasingly
ARRL demands Ambient’s BPL be shut down
The American Radio Relay Leage has again demanded that the FCC shut down
Ambient Corporation’s broadband over power line (BPL) pilot project
in Briarcliff Manor, New York. On May 21, the FCC called on the BPL equipment
maker and system operator to demonstrate it’s complying with all terms
of the Part 5 Experimental license authorizing the system, or face possible
enforcement action. In a May 31 letter to FCC Spectrum Enforcement Division
Chief Kathryn S. Berthot, ARRL General Counsel Chris Imlay, W3KD, contended
that it’s "long past time that the Commission enforce its own rules," and
again objected to the Commission’s "inexplicable inaction" in
the face of evidence the system is noncompliant. Imlay pointed out that the
FCC’s May 21 letter made no mention of Condition #1 of Ambient’s
Part 5 Experimental license.
"That condition requires that if any interference occurs, the holder
of the authorization will be subject to immediate shutdown," Imlay wrote." Interference
has repeatedly occurred, and it has been witnessed and verified by a member
of the Commission’s Enforcement Bureau staff. Yet no action has been
taken whatsoever to terminate this experimental authorization over a period
of more than two and one-half years. This is inexcusable."
Ambient operates the Briarcliff Manor BPL pilot program under Experimental
license WD2XEQ. ARRL testing as recent as late May indicated the system is
operating outside of the parameters of its FCC authorization.
The ARRL’s complaints regarding interference to Amateur Radio communication
from the Briarcliff Manor system date back to October 2003 and included supportive
technical reports and test results.
New measurements done May 24 by ARRL Laboratory Manager Ed Hare, W1RFI,
conclusively establish that the Ambient BPL system, in Hare’s words, "continues
to operate well above the Part 15 emission limits that are stipulated as a
condition of its Experimental license." Hare said his latest excursion
marked the third time his emissions testing in Briarcliff Manor showed the
system to be operating significantly above Part 15 emissions limits.
"The spectral masks in this system intended to protect some radio services
from interference work poorly enough in this generation-1 equipment, but
when the system is operated at excessive levels, strong interference is an
outcome," he commented. "By operating this system above the Part
15 emissions limits, Ambient is making it impossible for any electric utility
to use results from this experiment to reach any conclusions about the technical
and commercial viability of BPL."
ARRL seeking relief
The ARRL is going to court to attempt to get relief from recent FCC inaction.
The League has filed a federal appeals court brief outlining its case and
requesting oral arguments in its petition for review of the FCC’s broadband
over power line (BPL) rules. The League has petitioned the US Court of Appeals
for the DC Circuit to review the FCC’s October 2004 Report and Order
in ET Docket 04-37 and its 2006 Memorandum Opinion and Order. In its brief
filed May 17, the ARRL contends, among other things, that the FCC’s
actions in adopting rules to govern unlicensed BPL systems fundamentally alter
the longstanding rights of radio spectrum licensees, including Amateur Radio
"For the first time ever, the FCC has permitted new unlicensed devices
to operate in spectrum bands already occupied by licensees, even if the unlicensed
operations cause harmful interference to the licensees," the League said
in stating its case. "The orders under review reverse nearly seven decades
of consistent statutory interpretation and upset the settled expectations
of licensees without so much as acknowledging the reversal, let alone justifying
The ARRL argues that the FCC’s approach to adopting rules to govern
BPL flies in the face of Section 301 of the Communications Act, which requires
that operators of devices that emit radio frequency energy first obtain an
FCC license. "For years, the FCC has consistently read Section 301 to
apply to unintentional radiators, such as BPL devices, and has expressly embodied
that interpretation in its rules," the League’s brief recounts.
The Commission then compounded its error by asserting that BPL devices
do not fall within Section 301 at all, the League said. "This hail-Mary
attempt at justification is another unexplained departure from prior policy
that independently requires invalidation of the orders," the ARRL remarked
in its brief.
The ARRL contends that the FCC orders under review "jeopardize the license
rights of ARRL’s members and other license holders by authorizing providers
of a new device -- Access Broadband over Power Lines, or ‘BPL’ --
to send radio signals across the electric grid in the frequencies the license
holders occupy, but without having to obtain an FCC license."
The ARRL brief asserts that, for the first time ever, the FCC "has authorized
the operation of unlicensed devices that it concedes interfere with licensed
devices" and has declared that such devices "may continue operating
even where proven to cause interference." The FCC’s response to
the League’s brief is due July 2.

SBE MEMBERSHIP DRIVE WITH LOCAL PRIZE DRAWING
To help with the annual SBE Membership Drive, Chapter 124 is going to
have two drawings. One will be for members who bring new members into
the chapter, and another for the new members. We'll do this at the July
meeting. The prizes will be two HD Radios.
LIFE WITH HD RADIO
There are currently 12 FM HD signals (nine with HD2, and one with HD3)
and two AM HD signals on the air in the Portland market. For a complete
list, see http://www.ibiquity.com/stationlist_hdradio.php?theState=OR&sortBy=StnMark
HD Radio multicasting is now in the top 100 radio markets.
91.5 KOPB-FM realigned the bandwidths of their HD Radio subchannels.
HD1 was 49.00 KHz and is now 48.01 KHz, HD2 was 32.00 KHz and is now 32.03
KHz, and HD3 was 15.00 KHz and is now 16.01 KHz. They discovered that HD
Radio treats any subchannel under 32 kHz as mono, so their HD2 (which is
a music format) can now be heard in stereo. Thanks to OPB Engineer David
Switzer for the information.
The FCC has issued the text of their rules on digital audio broadcasting.
The effective date of the new rules is still 30 days after its publication
in the Federal Register.
When the rules take effect, the biggest item will be AM HD at night.
1190 KEX Engineer Shawn Cupples says they are ready to do HD in the 3- tower
directional night mode. 1330 KKPZ is a DA-1, so they'll just leave their
The next biggest item will be FM HD in the extended hybrid mode which
gives more digital bandwidth. I am eager to experiment with this.

Clay’s Corner for July 2007
Featuring News, Rumors and Views
From Usually Reliable and Irrefutable Sources
By Clay Freinwald
SBE Seattle Chapter 16
I’m writing this a bit early this time due to the
need to get my column written prior to leaving on my vacation trip to
Colorado (to visit Mom) as well as Boise to see our oldest Son get married.
Bound to miss something important in the news…
What I do know –
The battle of US Oil vs. KKOL is getting a lot of attention, as it should.
The story even made the front page of Radio World. This is involving
several members of our local Chapter. For me, I think it’s best
to stay neutral and just report on the story as it unfolds.
If you were at the last Chapter meeting you heard me present an overview
of changes to EAS, if you were not there, read on -
The big news this time around is the FCC’s second FNPRM related
Docket 04-296 and the EAS released on May 31st. This time they announced
a number of changes….
They finally adopted CAP (Common Alerting Protocol) as the foundation
for the EAS as we move forward. This obviously made SBE happy as we promoted
this heavily in our filings. If you are not familiar with CAP…I
suggest that you ‘Google’ the topic and become familiar with
the matter. It’s clear that there are a lot of problems with the
existing EAS, mainly the fact that it’s basically an audio system
designed for Radio. Moving EAS to an all text system will mean a couple
of major improvements–
- TV and Cable systems will be able to, at last, receive
detailed messages in text form…in fact, the text will be the same
as the voice message.
- The audio message will be distributed in
text form rather than in analog with the ‘reading’ taking
place at the stations decoder, thereby eliminating the problem
with poor audio
that has impacted
Reacting to the calls for the ability of EAS messages to
be understood by non-English speakers, they called for a meeting of the
to deal with the issues and put the matter on the fast track.
The Headliner in this action is the addition of the requirement
of EAS participants (this means Broadcasters) to transmit state
locally targeted alerts originated by governors or their designees.
this mean? It means that in addition to the requirement to air
President Messages (EAN’s) and the testing for them (RMT’s) we will
be adding messages from the State. In our case this will likely mean
that Washington State EMD generate messages will become an ‘must-carry’.
Additionally, for example, should King County or the City of Seattle
wish to warn the public about an event, they could contact State EMD
and that message would be forwarded to all Broadcasters who would be
required to carry it.
In this FNPRM, wire-line video providers were also given EAS participation
Finally, the FCC is very likely to be looking for a means of verification
that the EAS is indeed working well. This could mean more tests,
reporting requirements etc.
This May 31 announcement told us what they want to do….however
it did not tell us how they propose to accomplish it. Of particular interest
is the new must-carry state message requirement. Those of us that deal
with the technical aspects of EAS have been tossing around a number of
changes that might be required to make this work. One is to create a
new ‘originator code’ to the existing system. This would
enable the EAS units to be programmed to respond automatically to the
incoming state level message. Due to the fact that the FCC was silent
on how their goals will be handled, we are all left to wait for the details
to come for our answers. The major question is how will this effect existing
EAS units in place. My best guess is that it’s very likely we will
have to modify the in-place ‘boxes’. It’s likely that
not all, in place, EAS units will be able to be modified. In a couple
of cases, there is no longer any support for these. Then again there
may be new units coming to market.
Back to the subject of CAP. Washington State is not waiting for
the FCC to act to start using CAP and has already begun to use
in our state. Initially this change over will start slow due to
funding limits. I would think that TV stations and some news oriented
operations may wish to get in on the ground floor and purchase
To find out more of how these changes will impact us in this area,
consider attending, in person or via conference bridge, the next
SECC (State EAS
Committee) meeting on July 11th at 930 AM. The Washington State
EAS Remailer (email@example.com)
will have the details of the meeting.
As reported at the last meeting, KMCQ/104.5 has been testing from
their site on Radio Hill near the old Weyerhaeuser mill site in
Enumclaw. The Engineer from the parent company was at our last
sure what the next steps are for this facility. Apparently they
are going to study the data to help them select the best antenna
are rumors that the owners of this station hope to move it to Cougar
Mt and increase power. To do this the Bellingham operation on Mt
on 104.3 would have to move. Already this move-in has seen a number
of changes as the various owners play FM Radio domino’s.
Looks like there is an unlicensed operation going on in Olympia.
Recently while driving through the city I noted a very strong operation
stereo too. Understand that the Kirkland branch of the Commish has been
on their trail.
The FCC was handed a bit of a set back recently as they attempt
to deal with Indecency. I’m still confused by all of this. I fail to understand
how a wardrobe malfunction or graphic language are sinfully bad and yet
guns, violence and murder are just fine. I can understand that potty
mouthed rappers are not exactly what you want your kids to have to deal
with….However it seems to me that if you are going to try and outlaw
Immoral behavior that you should not be selective in the process.
Bad is bad, sin is sin. Then again there is the off button !
Sorry to report that Mr Wizard passed away. Don Herbert was 89.
Its tragic that we have so few folks that promote science and technology
Another passing is that of Ed “Hack” Hewson. He was a long
time leader at KING and was noted for launching NMT or Northwest Mobile
Television. He was 78 and lived in West Seattle.
A recent survey found that 65% trust advertising information on
TV but only 28% on Radio. Newspaper and Print came in about 50%.
The number of manufacturers hitching their wagon to HD Radio recently
took a giant step with the announcement that Sony is going to offer
On the HD TV front…Looks like we are starting to see some unified
effort toward getting the word out that analog TV’s end is coming.
SBE has started conducted Web based classed dealing with RF exposure,
NIER etc. We are looking at a class in our area sometime in October.
If you are interested, let one of the Chapter officers know.
July in Picnic Month for Chapter 16. Hope to see you at the event
on the 28th. Look for details elsewhere in this months Waveguide.
Gotta put the wraps on this for this month….Here’s wishing
you and yours a great summer.

DTV TUNERS & INTERFERENCE
By Tom Smith
Madison Chapter 24
On March 30, the FCC released a notice that requested comments on tests
the FCC took to determine the interference immunity of DTV tuners. The
FCC tested 30 fifth-generation DTV tuners taking 2,055 measurements. They
eight of the DTV tuners for more extensive test
The report concluded that all of the tuners were single conversion tuners
where the channel selected is converted to a lower IF frequency. The
tuners that the DTV allocation table and most of the early DTV tests used
was a double
conversion tuner in which the incoming TV channel is converted to a frequency
above the highest TV channel, about 900 MHz and then converted to the
standard 44 MHz IF frequency.
The Commission’s tests found that the DTV tuners exhibited many of the
same interference issues as analog TV tuners did. They were subject to interference
from second adjacent channels above and below the channel selected as well
as from a number of the former analog taboo channels. These channels were
the first, second, third, fourth and sixth channels below the selected channel.
These issues were found to occur when tuned to a station with low signal levels.
The sets also exhibited interference from channels located at seven channels
above the selected channel. This is the IF oscillator frequency. The DTV tuners
did perform better from the IF image channels located at 14 and 15 channels
above the selected channel. The IF interference was exhibited at moderate
The Commission did state that the digital tuners tolerated interference
slightly better than analog tuners. But because of the use of single-conversion
tuners instead of the ATSC-specified double-conversion tuners, none of
the tuners meet the ASTC specs for interference rejection that the DTV table
allotments was based on. This report was entered as part of the comments
of the unlicensed use of TV "white spaces." The results of this report
will no doubt impact the debate on allowing unlicensed devices on the TV bands
for some time.

FCC LOOKS HARD AT EAS
It was a banner day for the FCC, which also moved forward on EAS. The commission
adopted an order that requires EAS participants to accept messages using
Common Alerting Protocol after FEMA adopts standards.
NAB applauded the efforts "including much-needed outreach with state
and local officials to ensure a robust EAS system."
As we’ve reported, CAP involves the transmission of EAS alerts as text,
audio and video via broadcast, cable, satellite, and other networks. The FCC
says using this will make it easier for the disabled and non- English speakers
to receive alerts. The commission seeks comment on how best to deliver EAS
alerts as well as broader emergency and public safety information to these
groups, and commits to adoption of a final order within six months.
The agency also seeks input on how EAS is (or is not) working and whether
additional testing, station certification and assessments of how well the
system works after an EAS warning has been triggered.
The agency left open the issues raised in a petition filed by several groups
representing non-English speaking persons and directed its Public Safety and
Homeland Security Bureau to meet as soon as possible on providing emergency
information to non-English speakers.

ET Docket 03-65
Interference Immunity Performance Specifications for Radio Receivers.
On May 2, 2007, the FCC terminated two Notices of Inquiry and Proposed
Rulemaking on interference standards for radio receivers. The first dealt
with the amount of background noise or interference that a receiver would
be able to tolerate. The FCC proposed to set limits to how much noise
or interference an unlicensed device could add before it would affect the
ability of the receiver
to recover the desired signal. Comments were generally opposed and no
one provided any information on technical rules that would allow for the
of any technical rules.
The second inquiry and rulemaking pertained to receiver standards. The
FCC had wanted to create rules for making receiver standards on a broad
basis, but decide that it would make any receiver standards on the basis
of a frequency
band or service specific proceeding.
These proceedings were undertaken in order to allow for more unlicensed
devices to share various bands with licensed services.
MM Docket 93-17
An Inquiry into the Commission’s Policies and Rules Regarding
AM Radio Service Directional Antenna Performance Verification.
On May 4, a group of radio broadcasters, equipment manufacturers
and consulting engineers acting collectively as the AM Directional
Antenna Performance Verification
Coalition ("Coalition"), submitted recommendations to the
Commission on computer modeling to assess operation of AM antenna systems
The computer modeling would also be used to assess the effects of
construction of other towers near an AM direction array. A copy of the
be found on the FCC Web site at http://gullfoss2.fcc.gov/prod/ecfs/comsrch_v2.cgi.
Comments are due by July 23 and replies due on August 22.
WT Docket No. 96086
Development of Operational Requirements for Meeting Federal,
State and Local Public Safety Communications Requirements Through
The report and order and notice of rulemaking, despite the
length of its title, mainly concerns what the Commission
plans to do
with TV channels
This band includes four channels that are reserved for public
safety use. The rest of the channels will be auctioned off.
In the part
of the band current
occupied by channels 52-59, the band is divided up in blocks
that match the current TV channels. In the channel 60-69
band, there are
two 12 MHZ
channels 63 and 64 and 68 and 69 are for public safety; and
the rest of the band is divided into two 1 MHz pairs, two
2 MHz pairs,
two 5 MHz
two 10 MHz pairs. The FCC has auctioned of one 6 MHz pair
and a single 6 MHz channel in the channel 52-59 band, and the 1MHz
MHz pairs in
60-69 band. The single 6 MHz channel auctioned in the channel
52-59 band is being used by Qualcomm for its national MediaFLO
FCC has also auctioned off several licensed in one of the
one MHZ pairs on the channel 60-69 band.

PDX RADIO WAVES

Services, Inc., Portland
mike at brownbroadcast.com
Clear Channel is continuing its divestment of smaller market
groups, and in Oregon, Bicoastal is the big buyer. The Tiburon, California-based
has agreed to pay about $37 million for CC’s 14 stations in Eugene,
Medford, and Albany/Corvallis. Bicoastal currently owns a group in
Coos Bay/North Bend, and has agreed to purchase 5 stations in the Gorge
More than ever, this year’s NAB convention was internationally- oriented,
with an unprecedented 25% of the 108,000 attendees hailing from 141 foreign
countries. We also noticed a growing presence from a number of offshore companies
on the exhibit floors - many for the first time - particularly from China
and Latin America. There was also a lot of buzz about possible "conditional
access" (pay-for-play) uses for the HD subchannels, using addressable-receiver
technologies currently as currently used in Satellite TV and radio.
Meanwhile, the long-awaited $100 price point for HD radios has been
busted, with the Radiosophy HD boombox going for $99 retail, and an additional
$40 rebate currently offered until July 3. Yet, with recent studies
very low level of consumer awareness and excitement for the technology,
still a long road ahead.
With the sunset date of February 2009 for NTSC TV now firmly established,
many of us assumed that low-band VHF TV would be fully vacated, right?
a lousy frequency range for optimum DTV operation, right? And maybe, just
maybe, we might still have a chance to reclaim all or part of TV Channel 6
(82-88 MHz) for an expanded FM band. Well, not so fast. The latest Tentative
Channel Selection list still shows that there may be 8 DTV channel 6's (down
from 50 NTSC ch. 6 stations currently), and 22 DTVs on channels 2-5. By comparison,
I count 302 NTSC stations currently using channels 2-6. Most of these proposed
low-band DTV stations have current NTSC stations on the same channels. This
is an incredibly inefficient use of spectrum, IMHO. No wonder the purveyors
of unlicensed devices have their eyes on using so-called TV "white spaces".

SBE to Offer New Specialist Certification
Following recent changes in the FCC rules recognizing the viability of
digital radio and the official endorsement of multicasting, the National
Certification Committee of the Society of Broadcast Engineers (SBE) is
proud to announce its next specialist certification, Digital Radio Broadcast
This specialist certification will qualify an individual's knowledge
of digital radio broadcasting including audio processing, studio-to-transmitter
links and transmission of multi-channel digital program streams. The
roll-out of this specialist certification will be during the SBE National
Meeting, held in conjunction with SBE Chapter 20’s, Pittsburgh Regional
Convention, October 10-11, 2007, in Monroeville, PA.
SBE President, Chriss Scherer, CPBE CBNT remarked that, “while broadcast
and media engineering continues to evolve to cover a broad range of technologies,
certain aspects of broadcast engineering have a specific and specialized knowledge
base. This is why the Specialist Certifications were developed.”
The specialist will include knowledge of importers, exporters, the various
methods of combining analog and digital transmitters to antenna systems, delivery
of digital audio signals and data to transmitter sites, transmitter emission
mask measurements, AM and FM FCC rules, monitoring of digital signals and
bandwidth requirements for AM antenna systems.
Digital audio broadcasting (DAB) enhances a broadcast licensee’s ability
to not only better serve the public, but to provide means of additional revenue
in this highly competitive industry. Station owners will rely on the knowledge
and expertise of station technicians and engineers to implement this service
for their companies. With this specialist certification, the engineer or technician
carries the credentials needed for successful installation of digital radio
transmission systems. The specialist certification will focus on the current
in-band, on-channel transmission system being deployed in the U.S., and will
be called the SBE Digital Radio Broadcasting Specialist.
By becoming a certified specialist, a radio broadcast engineer can assure
his or her manager that he or she is up to date on the latest technology.
Digital audio broadcasting is different than traditional analog services.
An individual's ability to certify his or her knowledge of the entire system
rather than just a single part will bring confidence to both the individual
and station management.
To apply for the SBE Digital Radio Broadcast specialist certification,
applicants must currently hold SBE certification at the Broadcast Engineer,
Senior Broadcast Engineer, or Professional Broadcast Engineer certification
level. The exam will consist of 50 multiple-choice questions and one essay
question. Following the roll-out of the specialist certification, the SBE
will release an update to its CertPreview software of practice tests. To obtain
an application for the Digital Radio Broadcast specialist certification, go
