Random Radio Thoughts
Cris Alexander, CPBE, AMD
Crawford Broadcasting Company
Copper theft continues to be on the increase nationwide. I’ve talked
about it in these pages in past months. I’m going to address the issue
Last month, Crawford Broadcasting Company got hit at one of its AM sites,
and it was hit hard. This 50 kW five-tower directional antenna in Birmingham
was seriously crippled when copper thieves cleaned out – and I mean
cleaned out – the ground system close to each tower. They took the copper
strap, the bus plates, the (lightning) ground leads, and they even raked up
the copper screen around each tower base. Needless to say, the transmitter
choked without a ground reference to work against at any of the tower bases.
Our chief engineer and his crew of three got busy and made temporary repairs,
running a 2-inch strap from each ATU to the identifiable radial ends. That
got things back to full power… for a couple of days. The copper thieves
came back and took the strap used to make temporary repairs. We had new screens
on hand that we could have installed to effect permanent repairs, but those
would have been gone, too; I’m glad we didn’t install them.
These scumbags came to the site well equipped. They brought an air compressor
and some pneumatic tools to cut the bus plates. They even used the AC power
in the antenna tuning units to power the compressor.
Interestingly, they left the compressor in the woods on our property, under
some brush where it wouldn’t be easily seen, so they wouldn’t
have to haul it all the way back when they came to rip us off again. Our eagle-eyed
chief engineer, Stephen Poole, spotted the red compressor tank in the thick
brush, hauled it out and stashed it in one of our buildings. The scumbag thieves
came back, evidently looking for “their” compressor, and broke
into a storage building. As it turned out, the compressor had been stolen
from a neighboring business. Those folks were glad to get it back. Score one
for the good guys.
We installed a sophisticated video surveillance system at the site after
the first theft. Somewhat ironically, we had planned to do that all along
and even had the equipment on hand, but other priorities – little things
like keeping five radio stations on the air – had delayed that installation.
The theft of the ground system changed the priorities a bit.
The lengths to which copper thieves go to get at the goods has forced us
to implement some security measures that we have not until now considered.
At the Birmingham AM site, we’re replacing the wooden tower base fences
with tall, razor-wire topped chain link fences (yes, we have to ground them – what
a pain!). We’ve installed a large monitored security system including
zones at each tower base that alarm on gate-open conditions. We also plan
to install pressure pads and trip wires inside the fence at each tower base.
If we continue to get hit, we’ll put up a second security fence outside
the first with razor wire suspended between the fence mesh between the inner
and outer fences. This will force the scumbag thieves to use the gate for
entry. We are also exploring our options for an electrified layer inside the
inner fence (using a livestock-type fence charger). Our tower base surveillance
cameras will also provide an alarm on motion. Stay tuned for news on the effectiveness
of all this.
Even as we’re struggling to recover from the repeated blows at the AM
site, others (or maybe the same copper thieves) are hitting our FM sites.
They have attempted to gain entry to our transmitter buildings without success.
There is very little exposed copper at the tower bases (we have replaced all
the ground leads with aluminum), so they’re only left with what’s
inside and the transmission lines. I shudder to think about someone hacking
out a section of the 5-inch Andrew line at our big FM. But in anticipation
of this, we have on hand some spare parts – line sections, connectors,
reducers, adaptors and the like. It wouldn’t be much fun, but we could
sustain such a loss with minimal down time.
Clearly, we’re dealing with a whole new situation these days. And it’s
not just happening in Alabama (although it does seem to be worse there than
elsewhere). Sooner or later, we’re going to be dealing with aggressive
copper thieves in Colorado as well. My suggestion would be to prepare for
it now, before your $50,000 ground system turns into $150 in dope money.
Seven or eight years ago, my daughter Amanda (now an engineer at CBC-Denver)
was a Middle School student with an interest in meteorology. She wrote a letter
to Ed Greene, who was then doing weather at KUSA-TV as part of a class project.
He called her a few days later and invited her along with her mom and me down
to their studios to be his guests for the 4 o’clock newscast (we were
the “studio audience”). After the news, he gave us the grand tour
of the whole facility.
As a reformed television station chief engineer, I’ve seen my share
of TV facilities and spent years working in, over and under them. But I was
impressed with the KUSA-TV facilities and people.
This month, you’ll get your chance to see an updated version of what
we saw back then. The March SBE-48/SMPTE RM Section meeting is set for Tuesday
the 18th at KUSA-TV, conveniently located at 500 Speer Blvd. The technical
program is on HDTV measurements, but it also includes a tour of the facility.
So you radio guys, don’t let the TV technical topic keep you away. This
one is worth seeing.

The KE0VH Hamshack
The KEØVH Hamshack, article for March, 2008 It is amazing
to me the information that we share on the WA2YZT repeater here in the Denver
area. The other day, during a QSO with our good friend Randy, WAØTKO,
he described an incredible idea to me about putting old pl tone-less rigs back
on the air with the always now-a-days pl TONED repeaters. And he didn’t
have to spend $50 or more on the commercially available pl boards that may
or may not work with just about any radio. However, this will. With audio software
such as Cool Edit or most of the others on the market these days, you can generate
tones of many frequencies, including our standard amateur pl tones used in
just about all repeaters these days. You can then save these as mp3 files,
and put them on an inexpensive mp3 player, and have them loop for a constant
pl tone and then feed it into your old pl tone-less radio either parallel with
the mic input, or maybe insert it past the mic preamp in the radio. Randy describes
here what he did and thanks to him for providing the information. WHAT A GREAT
The procedure for attaching the mp3 player to my old Yaesu FT-720R 70cm radio
is fairly simple, thanks to Yaesu's providing a 4 pin "tone input" connector
on the rear panel of the rig. The required plug is the same size as one of
the small flat audio connectors that were used for years to connect a PC CDROM
drive's audio output to a sound card. I built a cable with a stereo 1/8" plug
on one end and the CDROM connector on the other. It was necessary to break
off some small ridges on one side of the flat CDROM connector to make it fit
the Yaesu tone socket. See attached "connector.bmp". Looking that
the FT-720R from the rear with the notched part of the tone input jack facing
down, the audio would be applied to the 2nd and 4th pins, counting from left
to right. Pin one is +12v and pin 3 is used for tone burst input. If the thought
of frying your mp3 player bothers you it would pay to double check the pinout
with a meter. The 12v will probably be there when the rig is keyed but I haven't
My mp3 player is an Olympus ws-310m combination digital voice recorder and
music player is but any inexpensive player should work as well. I downloaded
the tone mp3's from Sara Communications site, http://www.saracom.com/ham/ham.html.
They're named according to tone. The one I used to access the WA2YZT machine
was named 186.2.mp3. You can either load all 32 or just the ones necessary
to access your local repeaters. The length of each mp3 is 10 minutes so it
was necessary to set the player to continuously repeat the same track.
To set the tone level, connect the flat connector to the radio and the stereo
plug to the mp3 player's phone jack. Select the audio file corresponding to
the PL tone necessary to access a repeater an press the play button. Gradually
increase the volume on the player while keying the transmitter until a successful
key-up is obtained. It might be necessary to bump the level up a little more
to get consistent operation of the radio. That's all there is too it. My friend
Ed, WA4OHW, suggested that naming an mp3 for the repeater that you're trying
to access might solve the problem of trying to remember what tone is used by
For radios that don't have a tone input connector it will probably be necessary
to find an appropriate point in the microphone preamp for injecting the tone.
Coupling in the mp3 player's audio output with a small capacitor and or matching
network should provide some isolation and keep nasty voltages out of your "expensive
This simple and inexpensive "kludge" can breath some life into those
old rigs that are mouldering on shelves and in junkboxes because time and technology
have moved on and tones are a "given" when using most repeaters.
Here's the link that has the PL tones in wav and mp3 format: www.saracom.com/ham/ham.html
The owner of that site, Randy Reames, WAØTKO, is actually is advocating
using the PC's sound card as the tone source using the mp3 PL's but it's logical
that anything that can
play the sound file could be used as a substitute for a "real encoder".
Hence the idea of using a cheap mp3 player to to do the job.
Please don’t forget the SBE IRLP Hamnet the 1st and 3rd Saturdays of
the month. www.qsl.net/ke0vh/SBEHamnet.html for all the information.

From Chapter 24 - Madison
Read new NOAA director
Veteran meteorologist and amateur radio operator Bill Read, KB5FYA, was
named the new director of the National Oceanographic and Atmospheric Administration’s
(NOAA) Tropical Prediction Center, which includes the National Hurricane
Center (NHC) in January. Read had served as the Center’s acting deputy
director since August 2007. The NHC has a dedicated amateur station on-site – W4EHW – and
has worked closely with hams for decades.
In announcing Read’s appointment to head the Center, NOAA Administrator
Conrad Lautenbacher cited Read’s three decades of experience with the
agency and of his reputation as "a trusted consultant to emergency managers" in
the Houston area.
Joint venture good for ham radio
On January 16, Motorola announced that its subsidiary, MI, Inc, has successfully
completed its tender offer to acquire a controlling interest in Vertex Standard,
parent company of Yaesu, a manufacturer of a wide variety of amateur and professional
Dennis Motschenbacher, K7BV, Yaesu’s Executive Vice President for Amateur
Radio Sales in North America, told the American Radio Relay League (ARRL)
that he sees the joint venture of Vertex Standard and Motorola as "a
very good thing for Amateur Radio in general and Yaesu customers in particular...I
am really excited to see what the joint engineering capabilities of these
two huge communications companies will bring in the way of new technology
advancement for the Amateur Radio Service."
Motschenbacher continued: "There is a unique aspect of business that
comes with Amateur Radio. It’s not just about a radio. It’s the
relationship between the ham, the radio itself and the company that makes
that radio. This relationship in Amateur Radio is far different than it is,
say, between a buyer of a HDTV, the TV and the TV manufacturer. The relationship
in Amateur Radio is far more personal and ‘bonding,’ per se. I
am certain that we will do our utmost to ensure that Motorola understands
this delicate bond."
According to Motorola, "[t]he joint venture is expected to expand and
develop a comprehensive suite of products to address the rapidly growing demand
for 2-way radio solutions. Vertex Standard’s strength in the amateur,
marine and airband (avionics) segments provides Motorola with access to new
business opportunities. In addition, Vertex Standard’s solutions are
highly complementary with Motorola’s products and add greater depth
and breadth to Motorola’s Government and Public Safety business. The
venture also provides additional engineering talent for Motorola."

SBE Seattle Chapter 16
The good news is spring is fully underway here in
the great PNW…I had to
mow the lawn in late February….Trees are full of buds…The bulbs are
producing green shoots etc. But even with that, I managed to do something that
I have not done in many years…I managed to get myself stuck going up to
West Tiger on Feb 29th. It was a case of stupid-me as I tried to drive on a snow
covered road that had been melting. It was good going for a while, then the mushy
snow gave way at which point that bottom of the truck settled down leaving all
four some distance from the road below. I called Terry Spring on my cellphone
and asked about who he might have used to help in a situation like this as I
was some distance away from anything to grab with my winch cable. Terry tried
to call me back, but because cell coverage is so poor, he decided to bring me
the information in person. In the mean time someone else tried to get up there
to deliver an Argo Snow-Cat. He managed to get his truck and trailer stuck behind
me. So I contacted Dwight Small to come up and take me home. The next day we
went up to the mountain with the help of Cliff from Carks Towing out of North
Bend. Cliff got the fellow out that was behind me and then he managed to get
his 4X4 wrecker stuck. (and I forgot my camera) Cliff, with Dwight’s help,
got the wrecker out of a really bad situation…while I continued to dig
out my truck (it had snowed overnight)….They finally put a line on the
little truck and gave it a little pull and it was up on the then frozen snow
and easily backed out. It’s been some time since anyone has driven a conventional
vehicle to the top of West Tiger. Thanks to Alan Robinson and his snow-cat we
have been able to get up there when needs are critical. My mind is again wondering
if I can ever talk the boss into something that will travel – over- the
This winter has been especially harsh in the mountains with many pictures circulating
showing very deep snows and antennas buried in ice. In one case, On Feb 8th,
a good dose of freezing rain and/or sleet really did a number on the stations
on West Tiger with an apparent heavy coat of ice. STL’s stopped working
as did operation of the ATC Master Anten
na. Thankfully it was relatively short
lived as temperatures moderated.
Getting to a transmitter site is normally done by road, but when the road is
blocked by heavy snow, a 3rd party is usually employed as most stations don’t
own their own snow-cats. I recall when KBRD (Now KMTT) had their transmitter
on 3-Sisters Mountain where helicopter was the only access method for much of
the year. But what about a site that has no roads and no snow? Take a look at
this video - http://www.youtube.com/watch?v=X95vJC7bExE
On the other side of the country, I recently attended the 4th EAS Summit in WDC
while there representing SBE and our state. We heard that progress is being made
toward the creation of an advisory committee to assist FEMA in their work toward
creating our Next-Gen EAS system. Also present was Tom Beers, Bonnie Gay and
Claudia Fox from the FCC that are very much involved in this process. There were
4 of us from the SBE EAS Committee present as well, Richard Rudman, Gary Timm
and Adrienna Abbott.
I will be moderating a session at NAB this year on the topic of Next Generation
Public Alerting on Tuesday from 430 to 530 PM at the BEC. This will be a great
opportunity to learn about the new, Next-Gen, EAS equipment that will be coming
our way. Hope you can be there.
I suppose you heard about the recent big power failure in Florida….Turns
out the cause was a blunder by a field engineer who worked for the power company.
Understand that the punishment was a suspension and a requirement to attend a
refresher course for field engineers.
The FCC has been up to its – fine self – hitting some 52 ABC TV stations
for their role in airing an episode of NYPD Blue before 10 PM. Ouch!
According to the Neilsen Company, over 10% of the homes in the Seattle area are
not ready for the DTV conversion in Feb of next year. Really? I would have put
the total higher than that. I keep remembering how many people that are amazed
to learn that TV actually can come from an antenna! Meanwhile Wal-Mart is reportedly
now selling DTV/Analog converter boxes.
Another end of an era news item….This time that a long time TV Repair shop
in Fremont was closing it’s doors. It’s hard for us that have been
in the game for years to grasp the fact that defective TV sets today are simply
thrown away and not repaired.
Found it interesting to learn the Senator Cantwell is pushing a measure that
would provide NOAA with a second radar system. The present system, located on
Camano, Is. has a giant shadow to the SW caused by the Olympics. A quick look
at certain TV stations in the area that use the NWS radar clearly shows this.
The rationale is that without this shadow, their accuracy would improve. I also
suspect that the fact that some TV stations have better radar visibility to the
west than does the NWS might also be a factor. Talk is to put the new radar at
A former co-worker and later manager, Chuck Maylin is moving to Las Vegas to
manage the Beasley group there. Chuck and I worked together at KMO and later

Well the wondering is over….Blue-Ray wins with Toshiba throwing in the
towel thereby ending the HD format war. In this day and age of wars that drag
on and on …nice to see.
Congrats to KPLU as they recently broke ground (funny term) on their new studio
facility in Parkland. Engineering is being handled by Chief Lowell Kiesow, assisted
by Nick Winter.

In our business the word of the day is – pull back. Ad revenues are off
and sights are being lowered. This has resulted in a number of cut-backs that
have made the news, CBS, Citidel and others have been slashing expenses and in
many cases those expenses are employees. Newspapers are also in this mode with
reports that the NYT is cutting 100 newsroom jobs. In a couple of cases, Clear
Channel opted to take a couple of AM stations dark due to their poor financial
performance. This is like a brick and mortar operation shuttering their business.
Have not heard how the FCC feels about this, however it’s not the first
time. Here locally, over the years, we have had stations go dark during hard
times. Let’s face it, advertising is one of the first things to go during
lean times. Belo, owner of the KING/KONG operation in Seattle, recently spun
off their newspaper assets. The only bright spots are Cable and, of course, the
Belt tightening is likely to impact NAB this year as well. The annual event,
April 11th through the 17th, will see fewer faces as many stations and groups
have slashed travel budgets. Not all is bad news….Harris Broadcast reported
revenues were up 6 % thanks to sales for DTV hardware.
Could the sale of the Clear Channel TV stations be in question? Could be, according
the media reports. Some 56 TV stations are involved. Would not want to be working
A good number of Amateur Radio Operators (HAMS) were not pleased with the FCC
decision to eliminate the requirement for at least a basic understanding of the
code as a requirement to obtain an FCC license and appealed the decision…..They
Microsoft has come out on the other side of Broadcasters on the issue of use
of spectrum between TV channels for new technologies. That’s going to be
a really expensive fight with the money the MSFT can devote to their goals.
Yet another study has come out that finds that cellphone use may affect your
health. This one states that using a cellphone more than one hour per day increases
your chance of getting a brain tumor by 250%. Perhaps a good reason to use that
Blue-tooth so you can have your cellphone elsewhere. Certainly that will be the
case for vehicular use of these devices in our state this summer.
The Administration has whapped NPR with the announcement that they are cutting
their funding in the new budget. Meanwhile the Bush budget calls for an 8.3%
increase in funding for the FCC.
The battle over the desire of Sirius and XM to merge continues. Apparently lots
of out of the public view meetings going on...Predictions are going both ways.
Meanwhile the two Sat-Radio firms are cutting their losses with subscribers now
approaching 18 million.
Will NYC get a new radio station near 87.7 using TV Channel 6? That appears to
be what’s happening. Too bad the FCC does not simply allocate Channel 6
to aural broadcasting and give AMs first dibs on the channels if they will agree
to shut down their AM plants after a certain time. Seems to me that this would
resolve a lot of problems. Don’t think that this is only an east-coast
Congratulations to Tom Silliman who is going to receive NAB’s Radio Engineering
Achievement Award this year in Las Vegas. Congrats also to Jeff Mendenhall on
the receipt of a Fellow award from his company, Harris.
There is a lot of conversation going on now regarding increasing the power of
the HD Radio carriers. The reason for this is the concern that the coverage of
HD, and particularly HD-2 signals is weak. Look for a lot of discussion on this
item at NAB.
Received this email recently –
You need a Better Degree and we can help! Bachelors, Masters, MBA and/or Doctorate
(PHD) Academic Qualifications available from prestigious NON-ACCREDDITED universities ……..(phone

Just what we need our tax dollars spent on…..The U.S. Court of Appeals
for the District of Columbia Circuit has ordered the FCC to study the environmental
effect of towers built in the Gulf Coast region.
As you might know, Peter Dahl is no longer in the transformer/choke business.
The good news is Jeff Weinberg Harbach Electronics, has purchased the rights
to the name, the original transformer and choke specifications and designs, and
the design equipment thereby keeping the service going under the name of MagCap
Engineering. Amateurs and Broadcasters alike will certainly find this to be good
news. I can tell you that Peter’s work has saved many an engineer’s
day over the years.
The FCC has a new bank. For years we’ve been dealing with Mellon Bank…it
now will be U.S. Bank.
Bill Wolfenbarger reports a number of items of equipment recently stolen in Mid-January

The Winter/Spring 2008 Crutchfield catalog shows four low-priced car stereos

The NAB is supporting a 10 dB power increase for FM HD Radio. From http://www.nab.org/AM "Acting
upon a recommendation from the NAB Digital Radio Committee, the Board unanimously
approved a resolution to seek FCC authorization for higher-power operation of
FM HD Radio stations."
A 10 dB increase would bring the analog to digital effective radiated power ratio
up from 100:1 to 10:1. Poking around the websites of FM HD Radio transmitter
manufacturers, the ones who make solid-state models list them up to at least
3 kW in the HD-only mode, and some with the potential to go as high as 12 kW.
Since this is still just a proposal, no one is quoting how much analog plus 10%
HD they could put out. Assuming the FCC eventually approves a power increase,
stations who now have separate FM HD transmitters feeding separate antennas (like
KGON & KYCH) or "back feeding" combiners (like KRSK) would have
to buy bigger ones. Stations using "high-level" combining (like KNRK), "mid-level" combining
(like KBOO), or doing low-level combining using the new models of tube HD+FM
transmitters (like KWJJ is about to) might be stuck at the original HD power
level for awhile.

Static Line – Noise from All Over
In Satellite Radio, Sirius is purchasing XM, if government
approval is granted. Neither company has yet turned a profit. The industry
is early in its development and really has acquired only a small market
share in radio, so I suppose it should come as no great surprise that
such an action has been proposed.
I have more favorable experiences to report with the Pinnacle HD USB
tuner I purchased. While my wife and I were camping early in November, we
parked our 5th wheel in an RV resort about two miles west of Halstead -
within sight of the Hutchinson TV transmitter towers. I had not been able
to acquire KPTS (PBS) ASTC channels from Wichita, but had only tried on
the mono pole supplied with the Pinnacle tuner, and on my old pre-cable
attic mounted NTSC antenna. Very likely, the latter was a local special
antenna sold in the early 70's optimized for channels 3,8,10,12, and I can
get a snowy, but readable NTSC signal with it, but not HD. Typically at
that campground location, we optimize our RV roof mounted NTSC antenna for
channel 3 from Wichita if we want to see programming from them, and accept
the lesser quality on the other channels available in NTSC. If we decide
we don't want to watch channel 3, the RV antenna can usually remain in its
stowed position on the roof and we have all but about two VHF channels from
Wichita, although some have minor ghosting or may be snowy.
If the ASTC shows at all, it is of good quality, as one might expect.
A normal scan of the spectrum at the campground and while connected to the
monopole yielded ten ASTC channels and displayed a remarkable improvement
over the roof mounted RV amplified dipole shown on my NTSC set. Most of
the companies broadcasting in DTV are transmitting only the main channel
with whatever HD programming their networks have provided them, and if they
carry news at all, transmit it in 720p. The local PBS station is running
on the main channel; usually children's educational programming on the second
service, and a mix of main channel program time shifted and a new satellite
network which has similar content to the programming they carry on the main
channel. The local CBS station carries their usual programming on the main
digital channel, but does provide a weather channel with local radar, a
repeat of the last weather shows, and a crawl at the bottom with and severe
weather warnings, if any, or weather currents from different locations within
their viewing area. So only two of the ten were utilizing their multi-channel
capabilities, at least at the time of the spectrum scan I made. All in all,
the experience with the Pinnacle continues to be very favorable.
Providence Equity Partners Inc. reportedly may back out of a $1.2 billion
agreement to acquire Clear Channel Communications' 35 television stations
because the stations aren't performing as well as projected. However, following
this announcement, the FCC approved the sale. Go figure! Providence, you
remember, is the financial backer for Newport Television, a company formed
by former Wichita television executive Sandy DiPasquale, whose new company
has been operating out of former BlueStone offices in Wichita, pending its
planned move to Kansas City.
This acquisition will put Providence out of compliance for ownership
limits in five markets in California, Salt Lake City, Albany,NY, Jacksonville
and San Antonio. A request had been made to allow continued operation of
the stations for six months while the company tries to come into compliance.
The FCC granted the request in all markets but Albany. Providence also has
to work out cross-ownership problems with newspapers and broadcast media
in five of the markets. Although they pledged to do so when applying to
purchase Clear Channels stations, the credit crunch has apparently nixed
the quick sale of such high dollar establishments.
Commissioner Michael Copps was the lone dissenter to the transaction,
unhappy that Providence will have attributable interests in 86 TV stations,
99 radio stations and several other media properties. He is not a fan of
consolidation. It is said that plans for Clear Channel's pending $19.5 billion
takeover by Thomas H. Lee Partners Inc. and Bain Capital LLC will not be
affected by the outcome of the Providence backed sale.

WISCONSIN STATION ASKS TO END ANALOG
By Tom Smith
Chapter 24 - Madison
Pappas Telecasting, owner of WWAZ-TV Fond du Lac, has asked the FCC for permission
to end its analog TV transmissions on channel 68. WWAZ would continue operation
in digital on channel 44. In their letter to the Commission, Pappas Telecasting
claimed that it has loss nearly $9 million since the station’s inception
in 1995. There was little or no income generated by this operation according
to Pappas Telecasting. They noted that the loss of service to viewers in its
service area would be minimal as the station did not meet the minimum reporting
standards for Nielsen ratings and that most of the viewers had five or more viewing
choices besides WWAZ-TV.
The Region 45 700 MHz planning Committee, the Region 54 700 MHz planning Committee,
the Southeast Wisconsin Communications Resource/Support Group and the Dodge County
Sheriff all sent in letters in support, noting that they all had urgent need
of the spectrum for public safety use. The Region 45 700 MHz planning Committee
serves three-fourths of Wisconsin, the Region 54 700 MHz planning Committee serves
Southern Wisconsin and Northern Illinois including Milwaukee and Chicago and
the Southeast Wisconsin Communications Resource/Support Group also serves the
Southern Wisconsin area including Milwaukee. All four groups basically sent a
form letter in support of Pappas Telecasting. The Commission has only issued
a few public safety licenses in that band under special authority.
The FCC has allowed stations operating in the public safety bands of 700 MHz
band as well as stations operating on three channels already auctioned for commercial
use to cease operations and allow those winning bidders to start operations on
those channels. These provisions were part of the Auction Reform Act of 2002.

NTIA DTV SET TOP CONVERTER BOX COUPON PROGRAM
Beginning on January 1st, the NTIA began accepting applications for consumers
in the U.S. to receive up to two $40 coupons to be redeemed towards the purchase
of a DTV converter box (Set Top Box or STB) to continue to receive over the air
television after the February 17, 2009 cessation of analog transmissions from
full power stations. Response has been really good with over 3 million applications.
Interesting that Oregon leads the nation in per capita applications with over
180,000 to date. If you haven’t ordered your coupons yet, you can do it
online at: http://www.DTV2009.gov .
While the response has been good, confusion reigns with the public about what
exactly will happen on that now famous date. LPTV and Translators do not have
a mandatory date set, which means that many viewers in much of rural Oregon will
not see much change, but may need to take advantage of the converter box program
sooner than later. Only 3 of the 34 STB’s approved by NTIA for the program
have "analog pass through," which may make it difficult for viewers
in areas with a mix of full service and LPTV stations if they do not buy a box
with the pass through feature. NAB has recently stepped in to try to educate
the manufacturers and public about the feature and its impact on LPTV stations.
DTV TRANSITION STATUS REPORTS DUE THIS MONTH
If you are involved with the full power DTV transition, be sure to make note
that the FCC is requiring that all stations need to file a Form 387 DTV Status
report by the middle of February. Hopefully by now, given the recent clarification
of policies and procedures by the FCC, you have a clearer picture of where you
will be on February 17, 2009!
At OPB, we have two stations that are on their final channels, and three that
are moving back to their present "analog" channels. We’ve ordered
new solid state DTV transmitters and will be installing them during this coming
summer. Our FCC DTV status report will include technical modifications of the
proposed facilities to adjust what was published in the Appendix table of allocations.
I fully believe that the stations on high band VHF will provide excellent coverage,
hopefully to more than fully replicate that of the existing analog coverage.
SPRINT / NEXTEL 2 GHZ RELOCATION UPDATE
At this point in time, all stations should be finished with their equipment inventories
and most will be working with the vendors for final quotes on equipment and integration
services. For those of you that may have microwave licenses on 2 GHz associated
with translator or LPTV services, you have only until March 15th to get those
quotes filed. You must check on this now if you have any questions.
On the current schedule the Portland, Eugene, Medford, and Bend, markets will
not transition to the new band plan until August of 2009. Much of the new equipment
may not be delivered until spring of that year.
WINTER ADVENTURES IN OREGON BROADCASTING
I’ve included some recent pictures of the adventures of OPB Field Engineers
enjoying servicing some of the OPB sites. Remember this when you are warm and

winter so far!

FROM THE CHAIR
By Dennis Baldridge,
Chapter 24 Chair
Always do right — this will gratify some and astonish the rest." —Mark
Doing what is right is at the heart of the SBE’s Canon of Ethics —standards
outlined in four main areas encompassing 27 sections. The first area, "Professional
Section 1. The Broadcast Engineer will cooperate in extending the effectiveness
of the engineering profession by interchanging information and experience
with other broadcast engineers and students and by contributing to
the work of engineering societies, schools and the scientific and engineering

to strengthen others, making them better equipped and ready to succeed.
involves not only seeing that our work is done properly but allows
our own experiences to benefit others. Professional principles promote
throughout the industry.
The second section speaks of responsibility; knowing and doing what
is expected of us. When we as broadcast engineers maintain proper conduct
the profession, it reflects our personal character by demonstrating
our respect for those in leadership and the authorities they represent.
Let us all work to practice the SBE’s Canon of Ethics, particularly
in our professional life, by doing what is right.
Focus on the SBE Marketing Committee
Conrad Trautmann, CPBE, Chairman
At the 2007 SBE National Meeting in Pittsburgh, the SBE Board of Directors
voted yes on the formation of a new committee called the “Marketing
Committee.” I was lucky enough to be appointed the committee’s
first chairman. Committee members include Tom Ray of Buckley Broadcasting,
Vincent Lopez of WSYT/WNYS, Syracuse, Jim Leifer of Clear Channel Radio, Florida
and Gary Kline of Cumulus Broadcasting.
The primary goal of the committee is to increase the visibility of the
Society beyond the existing member base. Secondary goals include fostering
better communication amongst our members, assisting with our recruiting
efforts to increase membership, helping to write and review press release
and to assist the national office with our advertising efforts.
If you’re reading this now, you’re seeing the fruits of the committee’s
first successful initiative.
SBE-news was a team effort in which the committee, along with help from
Executive Director, John Poray and President, Barry Thomas, worked to
pull together details to create and distribute this. The logistics of sending
a national email are more than you might think. We had to find a vendor
to send the emails to over 4,000 email addresses. We needed someone who
send that many emails without getting caught in every spam filter. We
had to come up with a schedule for the year and decide what content would
each one. And we needed to be creative on ways to cover the distribution
expenses with advertising, so there would be no additional expenses to members.
We managed to do all of that and the response has been extremely positive
from our members. We’re hearing from people who don’t get to attend
meetings regularly. We’re getting important information about the society
into our member’s hands. We have a way now to be more timely on notifications
of events like our National Meeting. And we now have a way to reach you all
with time sensitive information and current events. We’re thrilled that
you’re allowing us to send this information to you and encourage you
to use the link below to forward this to friends of yours who are not members
and encourage them to join.
Watch for future committee projects including advertisements in our industry
trade publications highlighting the benefits of membership and certification.
We also are planning a membership drive emphasis and special promotion
for the week of the spring NAB show. If you have suggestions on things you’d
like to see from the society, please let us know. Thank you to my esteemed
committee members, President Barry Thomas and to John Poray at National for
their help and support of the committee’s efforts.
