Solutions for Meeting the CALM Act Requirements


Skip Erickson, Harris Broadcast


Sandwiches, chips, cookies, and soft drinks were provided.
A donation of $5 was suggested

The Commercial Advertisement Loudness Mitigation (CALM) Act was signed into law in December 2010. It requires television broadcasters and advertisers to adopt technology that will prevent overly loud commercials, giving them one year to comply. The Advanced Television Systems Committee in 2009 adopted best practices for audio which will become the standard by which the FCC will monitor compliance. Skip Erickson provided further background and explanation of these requirements and present solutions that broadcasters can adopt.

Random Radio Thoughts

Cris Alexander, CPBE, AMD
Crawford Broadcasting Company

Wireless Towers
Any of you with AM antennas probably get frequent notices of wireless/cellular tower construction or modification that may impact your directional patterns or ND circularity. This is a rule that the tower owners must comply with; they don't do it to be nice to you. Their hope is that you will simply toss the notice into the round-file without giving it a second thought.

In my company, we have a bunch of AM sites, directional and non-directional, and scores of those notices cross my desk throughout the year. There are two such notices on my desk right now that I have yet to look at. I can guarantee you one thing: I never toss a notice without doing a thorough investigation of the potential impact of the proposed construction or modification on my facility.

There are several possible outcomes from construction or modification of a wireless tower near an AM antenna site.

One is that there is not enough reradiation from the wireless tower to affect the AM station operation, so nothing happens. This, of course, is the best possible outcome and it is what in fact happens most of the time.

Another is that there is some reradiation from the wireless tower and it influences one or more of the monitor point field intensities in an upward direction but not enough to push any of the points over the limit. This is perhaps the most insidious case. Because it does not push the MP(s) over the limit, the effect is often disregarded. Later, however, either due to ground conductivity change (freeze/thaw) or the cumulative effect of one or more additional reradiators, the station could find itself having to reduce power to maintain monitor point field intensities. If there is any upward change in MP field intensity, you should insist that the reradiator be detuned.

Yet another possible outcome is that there is a significant impact on the field intensities at one or more monitor points. Sometimes the MP fields increase, and sometimes they decrease. The cause is often a standing wave that is set up along the null radial path, and depending on whether the MP location is situated in a trough or a peak, the MP can go way down or way up. Either situation indicates significant reradiation and requires treatment with one exception - more on this later.

Another possibility is that the monitor point field intensities all stay below the limit but a partial proof shows that the far-field inverse distance field (IDF) values exceed the standard pattern value for one or more radials. This definitely requires treatment of the reradiator by detuning.

Finally, it's possible that a reradiator can cause significant scalloping in the main lobe while not having a significant impact in the nulls or at the monitor points. This is often the case in areas of poor conductivity where the reradiator is located in the main lobe. It's the station licensee's option whether or not to treat this, but the best course of action is to detune the reradiator.

From these different possible outcomes, it should be obvious that it's impossible to determine the effect that a wireless tower is actually having on an AM antenna by either measuring the MPs or doing a partial proof. Wireless operators want to do the minimum required by the FCC rules, so unless you insist on more, they will simply measure the MPs before and after construction/modification, and you will likely get a letter stating that the wireless tower had "no effect" on the AM antenna or array, even if the MPs went up but not over the licensed limits.

Moment method modeling ("MoM" for Method of Moments) offers some real analytical tools in such situations. It's relatively easy to model an AM directional or non-directional antenna with the wireless tower and then do a careful analysis of both the resulting pattern and/or the null and lobe radials to determine what, if any, effect the wireless tower will have. Quite often, the MoM model will show the standing wave that I mentioned earlier with the MP locations positioned in the peak, trough or somewhere in between. In many such cases, this standing wave will become dampened with distance and the IDF line will settle down to a value below the standard pattern value by 20 km or so, indicating that no interference will result to other stations as a result of the reradiation. AM stations licensed pursuant to the MoM rules [§73.151(c)] can simply ignore the reradiator. This is the exception I mentioned earlier. Stations licensed with a conventional proof will have to insist on treatment of the reradiator or else take the opportunity to get MoM licensed.

The bottom line here is that you can't just toss those notices in the trash and hope for the best. Sooner or later you will get bitten. If nothing else, the incremental cumulative effect of multiple minor reradiators will eventually push the MP field strengths above the licensed limits. That's when you'll have to reduce power and deal with the problem at your own expense. Don't let that happen.

The KEØVH Hamshack

Jack Roland

The KEØVH Hamshack for April 2011
The NEW and IMPROVED SBE IRLP Hamnet page is up with new and updated information. Just go to for all the details on how to join in! The SBE IRLP Reflector, node 9615 also has a new website with info at Check out all of our information there.

And this month we glad to announce we are now also on Echolink for the SBE IRLP Hamnet! IF you are radio-less, or have no IRLP node near you, now you can participate in the net, & get on the IRLP reflector anytime, all from your PC with Echolink.

Details on how to get on Echolink are at Simply download the software, install and go thru the registration process, they essentially just want to see your ham license (I scanned a copy of mine and emailed it to them). It is free and easy, although it will take a few days to get the confirmation back.

Then, setup the software on your computer, they also have a great helpfile on how to deal with routers and firewalls, and then you can do a search for *SBE* or node number 96150, and you can connect that way. We even had an interested amateur from Moscow Russia check into the last net of February. All Amateurs and Broadcasters are welcome!.

If you have any questions, please send me an email.

The KE0VH Echolink Screen in QSO with WA2ZST at CBS-TV via the IRLP Reflector 9615 connected to the WA2CBS repeater in Manhattan.

And the SBE Reflector 9615 has a great website to check out at

Last month I wrote of the new station interface I am using at KEØVH using an old discarded Starguide III Satellite receiver chassis. It has really proven to be a great addition to my home ham station. It of course being custom made does all I want it to and still has room for more additions should I decide. I have made it able to key the HF radio for both digital modes, and regular PTT from my microphones. Using my station mixer I can also feed any audio source into my (HF at this time) radios for sending SSTV, PSK31, EasyPAL which is a digital SSTV program, and virtually anything I can load on the station computer. I have installed it and it is operational now, and it really works well.

I will be happy to send a copy of the schematic that I drew using the free Express PCB program available at I have been using this software for years and it does nearly as much as some of the more expensive programs. Much easier to use too, plus the website has many features such as providing circuit boards for the schematics you might draw at a very good price.

On March 1, we had a burn thru of the master antenna on Cheyenne Mountain. My station KBIQ is one of the stations feeding that antenna along with several others, including Citadel and Clear Channel stations in Colorado Springs. I have put up a compete set of pictures of the damaged feed lines and the master antenna on my techham website, Here is a picture of the center conductor from the 6 inch feedline.

And if you remember from a couple of months back I had a picture of Joe Walsh, of the Eagles rock group (ed. and of the James Gang and solo albums before that) pictured next to his vintage AM station, yes he is WB6ACU.

Craig, KCØKP writes:

"Read with interest the segment on Joe Walsh in your column in the SMPTE SBE newsletter (January 2011 issue ( Joe used to have a zero call sign when he was living in Boulder. He was a member of the Rocky Mountain Radio League and attended meetings when they were at the Westminster city hall. He even brought his Moog synthesizer to a meeting demonstrating it to the group. He was active on 2 meter FM popping up at odd hours.
73, Craig kc0kp"

A great website to see when visible satellites including the ISS and more will be visible at your location by zip code:

Want to see a great site on the restoration of an old ham transmitter, then go to The article is called "A Work of Art - A Collins Time Capsule Found."

That's it for this month, 73' hope to hear you on the SBE IRLP (and Echolink) Hamnet.

Clay's Corner

Featuring News, Rumors and Views
From Usually Reliable and Irrefutable Sources

By Clay Freinwald
SBE Seattle Chapter 16

Clay's Corner for April 2011

As I sit here in front of my trusty 'puter....I just received an email from Terry Spring reporting that he was getting reflected power alarms on his antenna at West Tiger. Ahhhh, is it not supposed to be spring? The summit of this popular broadcast site has been snow-cat only (if you don't count snowshoes) since late February. Finally, on March 28th Terry and I were able to drive to the top....It must be SPRING!

A couple of major changes in the world of radio engineering in our town with the announcement that Ken Broeffle and Jeff McGinley are no longer employed by Clear Channel.

A couple passages to note -

First the passing of Barry Ackerley. Barry was best known as a former owner of the Sonics. He also owned a number of broadcast stations in Seattle, KUBE, KJR etc.

Another broadcaster is no longer with us, Buzz Barr. I have a lot of fond memories of working the Buzz in the middle 60s...We had a great time.

Perhaps you did not catch the passing of Harry Coover. Harry is credited with the invention of Super Glue. Bet you did not know the official name for the adhesive - Cyanoacrylate. Like a number of important discoveries, this one was also by accident. Harry was 94.

Our area is going to represented well at this years NAB Convention in Las Vegas with presentations by Tom McGinley and Jim Dalke. I am very pleased that Andy Skotdal is going to be telling the story of KRKO and what a story that is!

Again another broadcast tower has come down in this past month, unlike KRKO, this was not vandalized. This was the tallest tower in Wisconsin, near Eau Claire, about 90 miles east of St. Paul....The site of WEAU-TV (Ch 13) and WAXX- FM. The nearly 2000 foot guyed structure came down in a wind and ice storm. Even though winds in the area were reported to be about 40 mph, there were reports that the tower at 3 ½ inches of ice. How the station got back on the air is interesting. Apparently the station sent its programming to another station in the market (WQQW, Ch 18) which put WEAU on their 18.3. Another station, in another market, WXOW, put the station on its 50.1. In the end, even though their tower was in pieces on the ground, they were able to cover 87% of their market. Talk about broadcasters helping broadcasters! The downed tower was reportedly erected in 1966. Can you imagine the sinking feeling you would have responding to a call that your station was off the air to find that the tower was laying in a mass of twisted steel on the ground?

Here in Seattle the stage is apparently set for what some are calling the battle for the future of our towns own Fisher Broadcasting (KOMO/KUNS/KPLZ/KVI etc) Apparently there are those on the Board and feel the best way to resolve their frustration with firms financial performance is to sell. Bowing to pressure for more return, they have put on the block the Green Glass Palace, aka, Fisher Plaza. May 11th is the date for a meeting that may decide the issue.

Meanwhile over at Tribune on Westlake Ave ....Things are still not resolved with their parent company. Reportedly a Bankruptcy judge has not determined how to proceed with plans to reorganize the company under Chapter 11....So the matter drags on and on.

Every once in a while I write about a radio broadcaster that gets fined for putting a telephone caller on the air without first gaining permission to do so. Now comes word that two TV stations were each fined $4000 for airing video news releases during newscasts without properly identifying where they came from. This is a form of the old requirement for Sponsor Identification. You'd think that by now........

The FCC is apparently intent on squeezing some 120 MHz of spectrum for Broadband etc out of the hide of broadcasters. Not everyone is pleased with this concept. The NAB and others are fighting back. Reportedly groups representing more than 200 TV stations have banded together to fight the idea. Representative Greg Walden from neighboring Oregon and a fellow who understands broadcasting is openly skeptical of the FCC's plans. This is a battle that is far from over. Some are saying that it will be decided in Congress rather than at the FCC. One broadcaster made a great point explaining that point-multi-point distribution is the most spectrum efficient...Far more than any broadband scheme, including 4G. Look for more use of the terms - Broadband and Broadcasting. Now we can only hope that the technophobes in WDC will understand.

Congrats to KING-TV for winning a national photography award. The station was chosen as Large Market of the year based on a number of pieces the station produced.

Mergers are certainly in the news. One of the biggest in some time impacts a local firm with AT&T announcing it's buying T-Mobile. T-Mobile is, as you may know, based in the Seattle area.

The recent earthquake in Japan has caused a lot of us in this area to again think about what happens when a big one takes place here. The 'shaker predictors' are all in agreement that we will have a huge quake in this area, it's just a matter of time thanks to the subduction zone we have off of our coast. Thankfully we don't have any nuke-plants near the ocean and we are, somewhat, isolated from the ocean...However a tsunami will certainly come in the Straight and impact a lot of low-land areas of Puget Sound. Compared to the last big quake we had here (Nisqually) the one in Japan was huge and it lasted for a very long time. A 9.0 would certainly make this area with all its elevated freeways and waterways impossible to get around. Just hope I'm gone by then.

There is a potential impact to our industry due to the fact that a number of suppliers of not only equipment but components come from Japan, some from the areas that were significantly impacted. Because a great deal of the power in Japan comes from these knocked out plants, many industries are going to be hurting for some time.

Are you ready for the latest NIER health scare? PG&E, the big utility in California, has, for some time, been installing what they call their Smart Meter which contains a tiny radio transmitter that transmits power consumption to the company. Someone, probably with a lot of spare time and belonging to an organization that fears anything they don't understand, concluded that these meters are a health issue. PG&E is apparently agreeing to remove the critters but are passing the additional cost on to the customer to the tune of $135 upfront and $14 per month (I assume the cost of the now required meter reader). The utility maintains that the meter transmitters are safer than many items that are commonly used in the average home. In my experience, those that complain are likely to be the type that get a 'deer in the headlights' expression with the simple mention of terms like ....Mathematics or (horror) Science. On the plus side, if they are willing to pay for the reader to visit their meter, great. At least employment is created.

Congrats to former Seattle guy, Marty Hadfield and the crew at Portland's Alpha Broadcasting on the completion of their new digs in the Rose City. Several folks from this area have been down to visit. It was the cover story of the latest Radio Magazine.

Congrats go out also to Andy Skotdal who recently received a CP for his 2nd AM in Everett. Andy is a guy that should have a metal for his efforts at overcoming the opposition of many. Let's not forget the bozo that took down a number of his towers a while back. The new signal will be on 1520 and will share the site with KRKO.

Every once in a while you hear about a broadcast station that did not have a security system in place getting ripped off. In this case a small LPFM near Columbus Ohio was broken into. I am constantly reminded of the need to make sure that our facilities are secure and that we have 'monitored' alarm systems.

In a recent column I wrote about mobile TV and asked who was doing it here in Seattle. Tim Schall of KCTS-TV responded this way -

Hi Clay:
Your most recent 'corner' contains a paragraph about mobile DTV and Belo and ends with a question about 'who else' is doing it.
Here in my shop at 401 Mercer, and everywhere else I've tried for that matter, I can receive the following mobile DTV stations:
4-1 M/H KOMO-4
4-2 M/H ThisTV (KOMO's secondary DTV service)
7-1 M/H KIRO
16-1 M/H KONG
51-1 M/H Univision
Note that 4-1, 4-2 and 51-1 are all emanating from Fishers physical channel 38 transmitter on Queen Anne. (Has anyone told those guys you can do digital radio on FM?) 51-1 M/H >IS NOT< broadcasting from West Tiger. 7-1 is on physical channel 39 from Queen Anne and 16-1 is on physical channel 31 from Queen Anne.

Thanks Tim -

A recent video surfaced where some employees of NPR made some statements that quickly got them fired and resulted in the President and CEO stepping down. This renewed the call by some in Congress to pull funding from NPR and public broadcasting. A proposal to do just that passed in the house but died in the Senate. Certainly with everyone trying to reduce expenses, public radio and TV have something to be concerned about. Perhaps it's time to permit these stations to obtain revenue the same way commercial broadcasters do? As if NPR needed more bad news..... Garrison Keillor, host of the popular A Prairie Home Companion, announced he is retiring in the spring of 2013. On the plus side, nation wide, contributions to NPR stations are way up.

Here in Seattle we have a couple major NPR stations, KPLU and KUOW and KVTI from Tacoma. Joining those radio stations that are listener supported this summer will be KING-FM.

The new owners of KDDS and KTBK, Adelante Media Group, are in the process of making a number of improvements to their stations which target Latino listeners. The reason for the investment can be found in the census figures that show 16% of our population is now Latino. That's a huge segment. If a broadcaster can deliver the majority of that group, he is ahead of just about everyone else. I have to wonder why some of the major radio broadcast owners have not awakened to this fact.

Congratulations to KIRO -FM in Seattle as they were nominated for NAB's Crystal Radio Award. The station is one of 50 nominated and the only station in this market named. The winner will be announced at the Radio Luncheon at this months NAB convention in Las Vegas.

Speaking of KIRO, It's been reported that WTOP in Washington DC is the nation's highest billing radio station. The owners of KIRO, Bonneville, recently sold the station.

Pirate Radio operations continue, and so does the FCC's efforts to get them off the air. In this case the FCC really threw the book at a Gabriel Garcia of San Jose, Ca. Over a period of approx 4 months the FCC tracked this fellow on a number of frequencies and locations. One of the parties that complained with the FAA (That will do it) the tab?
25 Grand.

It's nice to know that you have readers. As a demonstration of fairness...Here's a letter recently received -

I have to take issue with the comment about "the lack of battery powered TVs these days that can receive ATSC". In fact, there are millions of them. There are many different brands, and many have a built in rechargeable battery as well as a 12v plug to charge in your car. They can be purchased online for $49.00 or less. Example:

I'll admit the whip antennas are lousy, but most of these portable TVs seem to have good reception if you add a better antenna. In many cases a $5 bowtie will work.

During a natural disaster, there might not be internet or cell service in some areas. At this price, I think everyone should have one of these TVs for their disaster kit along with a portable radio. (I may be a little biased, but being that our TV station is the EAS local primary station, I think I should have that right.)

These TVs are great during power outages. My home is on the same substation as our transmitter. During the last outage I was able to verify that our channels were operating on the generator. They have audio / video inputs so they are a handy small and lightweight video monitor. For station engineers that still have to maintain analog translators, they also receive NTSC.

Thanks for reading my Column, Mike, I stand corrected.

I'd like to add that I was with Terry Spring the other day visiting a transmitter site here in Western Washington and watched him pull out his laptop and plug in something that looked like a Wi-Fi adaptor into which he connected a small antenna and - presto - he had a laptop TV that would receive NTSC as well as ATSC. Cool.

Talk about bad luck - How about the group that shelled out 4.4 megabucks at an FCC Auction for an FM station in Omaha, Nebraska. When they tried to build the station they found out there was no location available for them to build the station on 107.7 that would permit them to cover their city of license and be acceptable to the FAA. Apparently the Commish will give them their money back. Yes we have a 107.7 here in Seattle.

Apparently Mexico will be joining the US in the use of HD Radio with their version of the FCC giving the green light to the technology in our neighbor to the south. The future for HD Radio in this country on FM appears to be bright with an ever increasing number of radios available. However HD has been fighting an uphill battle in other parts of the world where DRM and other system appear to have the upper hand.

As you know, I frequently like to leave you with something to ponder. This month credits go to Dwight Small for the following tidbits.
> Light travels faster than sound. This is why some people appear bright until you hear them speak.
> Some people never really grow up; they only learn how to act in public.
> An argument with your boss does not determine who is right - only who is left.
> How come the evening news begins with 'Good Evening,' and then proceeds to tell you why it isn't.
> To steal ideas from one person is plagiarism. To steal from many is research.
> A clear conscience is the sign of a fuzzy memory.
> You're never too old to learn something stupid.

Well folks, that's it for this Month - Thanks for the read and keep those cards and letters and emails coming my way.

Amateur Radio News

Compiled By Tom Weeden, WJ9H
Thanks to Madison Chapter 24

A proposed bill in the US House of Representatives has alarmed broadcast auxiliary users and amateur UHF operators due to proposed reallocations of their frequencies. On February 10, Representative Peter King (R-NY-3), Chairman of the House Homeland Security Committee, introduced HR 607, the Broadband for First Responders Act of 2011. The bill has been referred to the House Energy and Commerce Committee, which handles telecommunications legislation. HR 607 addresses certain spectrum management issues, including the creation and maintenance of a nationwide Public Safety broadband network. As part of that network, the bill provides for the allocation of the so-called "D-Block" of spectrum in the 700 MHz range for Public Safety use.

The D-Block consists of two, 5-megahertz-wide segments of spectrum (758-763 and 788-793 MHz) that became available when the FCC ended analog television broadcasts in June 2009 and reallocated the 698-806 MHz band for Public Safety and commercial broadband. It was anticipated that the D-Block would be auctioned for commercial use. There are several bills in Congress providing for the allocation of the D-Block for Public Safety use, and HR 607 is one of those. But HR 607 uniquely provides for the reallocation of other spectrum for auction to commercial users, in order to offset the loss of revenue that would occur as the result of the allocation of the D-Block to Public Safety instead of commercial auction. HR 607 lists the paired bands of 420-440 MHz and 450-470 MHz among the bands to be reallocated for commercial auction within 10 years of its passage.

"Of serious concern to the ARRL is the inclusion of the 420-440 MHz amateur allocation in the list of frequencies to be cleared for auction," said American Radio Relay League Regulatory Information Manager Dan Henderson, N1ND. "The ARRL and the Amateur Radio community agencies and understand their desire for an interoperable network; however, the inclusion of most of the amateur 70 cm spectrum as one of the replacement bands is illogical and unacceptable. The 420-440 MHz band is not Public Safety spectrum and should never have been included in any spectrum swap of Public Safety allocations."

Saying that the ARRL Washington team has already begun meeting with key Congressional staff on Capitol Hill, Henderson noted that Amateur Radio already shares the 70 cm band on a secondary basis with the governmental radiolocation services. "To be sure, the ARRL will vigorously oppose this legislation in its present form."

● Amateur Radio has moved a step closer to a medium frequency (MF) allocation below the AM broadcast band. During the first week of the Conference Preparatory Meeting (CPM) for the 2012 World Radiocommunication Conference (WRC-12) of the International Telecommunication Union (ITU), held in Geneva February 14-25, delegates completed the drafting of nine pages of analysis of the technical and regulatory issues related to WRC-12 Agenda Item 1.23: consideration of a possible secondary allocation to the Amateur Service of about 15 kHz somewhere between 415 and 526.5 kHz. Two possible methods of satisfying the agenda item, along with the possibility of there being no change (and therefore no allocation), are set out in the CPM Report, along with the advantages and disadvantages of each. WRC-12 will be held in Geneva next year from January 23 to February 17.

Just when you thought you could forget about ionizing radiation exposure... Here's a link to a graphic that shows that it is all relative. (Thanks to the CGC Communicator for the link.)

All the current exposures are in micro- and millisieverts. Remember rems? 1 sievert = 100 rem. From Wikipedia: "Professor Rolf Maximilian Sievert (6 May 1896 - 3 October 1966) was a medical physicist whose major contribution was in the study of the biological effects of radiation."

Alpha is simulcasting 750 KXL on 101.1 which is now KXL-FM, bringing "News/Talk" to the mysterious FM band but with the stereo pilot turned off. The format change was kind of weird for me having once been Chief Engineer of each of them. I went to the privately-held KUFO wake at a bowling alley. They have parked the KUFO call letters on 970.

However, they may be onto something. 50 kW 1500 WTOP Washington DC began simulcasting their all-news format on 103.5 FM then changed the AM's format to "Federal News Radio" and the call letters to WFED. Now WTOP on FM is the top billing radio station in the country: $57 million last year. WDC is the #9 radio market. The #2 billing station is KIIS-FM in Los Angeles, the #2 radio market.

Not to be completely outflanked, Clear Channel's1190 KEX now has an FM translator on 102.3 with a blistering 99 Watts from Mt. Scott. View the 60 dBu coverage map here.

Alpha already has Sports on 95.5 FM The Game KXTG, but it has yet to really beat Entercom's 1080 The Fan KFXX. Some folks think that Alpha will someday put The Game on 750, and put music back on 95.5, possibly to compete with Clear Channel's103.3 K103 KKCW which has been #1 for years and was in the double-digits (hard to do with PPM) in the Holiday ratings.

On March 11th, my wife Patti and I were asleep in a hotel room in Cannon Beach when the phone rang at 3:45 AM. "Please meet in the lobby at 6 AM prepared to walk to higher ground" the woman at the front desk said. Looking at The Weather Channel and seeing that nothing was going to happen there until about 7:30 AM, we immediately packed up, went home, and went back to sleep.

I'm not going to the coast again without my NOAA Weather Radio. Had we heard the Tsunami Warning at midnight, we would have gone home then!

ANOTHER TIME-WASTING LINK . They have somehow archived whole web sites starting in the 1990s. I was the first webmaster of and there is a copy of it from 1996. Unfortunately they don't have when it was only on AM.

They have revamped They finally removed all the former CBS-Portland stations which never added HD.

There are 14 FM HD signals (twelve with HD2, and two of those have an HD3) and three AM HD signals on the air in the Portland market. Go here for a complete list.

There are now over 1000 multicast stations and 100 HD Radios to choose from. See the buyer's guide here.

SBE News

SBE at the 2011 NAB Show

February 3, 2011 - The Society of Broadcast Engineers has been NAB's organizational partner for the presentation of the NAB Broadcast Engineering Conference (BEC) since 1995. Following previous years, this year's BEC will be the largest and most comprehensive broadcast technical conference in the world. The conference begins with the SBE Ennes Workshop on Saturday, April 9 and ends on Thursday, April 14. SBE will be very active with a full slate of meetings and events and will have a busy exhibit booth during the week. SBE Exhibit Booth SBE's exhibit booth will be on the second floor concourse of the Las Vegas Convention Center South Hall, Lobby Booth 29. The location is just up the escalator from the South Hall main entrance and just outside the entry to the exhibits on the second floor. This is the same location as in recent years. The BEC technical sessions will be located nearby, in the South Hall second floor meeting rooms.

Be sure to plan to visit the SBE booth while at the convention. We will have all of the SBE published handbooks, technical books from major publishers and the SBE CertPreview. There will also be several of our popular SBE logo items for sale. Membership renewals and new memberships may also be transacted at the booth. SBE staff and national Board members will be at the booth to answer your questions about membership, certification, educational programs and regulatory issues.

Booth Hours
Sunday 2:00 pm - 4:00 pm
Monday - Wednesday 9:00 am - 6:00 pm
Thursday 9:00 am - 2:00 pm

SBE Spring Membership Meeting Highlighting the week for SBE will be the annual spring Membership Meeting, held on Tuesday, April 12 from 5:00 pm to 6:00 pm in the South Hall at the Las Vegas Convention Center (room to be announced). We will be recognizing a number of our local chapter certification chairs during the meeting. Prizes will be given away to those who attend.

SBE Exams held during the NAB Convention

Don Borchert Broadcasters Clinic Fellowship

Chapter 24 - Madison - Following the passing of Don Borchert, long time Chairman of the annual Broadcasters Clinic, the program committee sought a fitting way to remember him. The Don Borchert Broadcasters Clinic Fellowship presents the opportunity to attend the Clinic to someone who would not have otherwise been able to attend for financial reasons. The program will cover the expenses of the annual recipient(s) under the financial support of all four Wisconsin SBE Chapters and independent donors. In addition the WBA will provide complimentary registration. In this way the program committee felt the name Don Borchert would remain associated with the conference he so dearly guided for over 30 years.

2011 is the kick off year for the Don Borchert Broadcasters Clinic Fellowship. If you or someone you know might benefit from this Fellowship please go to www. and click on the "Broadcast Clinic" button. There you will find an application form.

Free Webinar by SBE

Free Webinar by SBE on Disaster Recovery - April 28
For most engineers, the disaster recovery plan is a file on their hard drive that is a rarely updated and sketchy plan on what should be done if the station is destroyed. Find out what real world lessons in disaster planning were learned when the CBS and Fox affiliate in Grand Junction, Colorado burned completely to the ground and the Super Bowl was just two weeks away. This webinar also includes checklists and other templates to aid in disaster recovery. FREE for SBE Members thanks to Harris Corporation; Non-Members $39. For more information go here.

Newest SBE University Course

Newest SBE University Course - Broadcast Audio Processing
The newest course on SBE University, Broadcast Audio Processing, was created for the intermediate-to-experienced broadcast engineer who is already familiar with the basics of good broadcast engineering. A member of the SBE who recently took the course said, "This is the second course I have taken in the past two months and both experiences have been extremely positive". The course has nine chapters and depending on your knowledge of the subject, could take 5-8 hours to complete. Topics include loudness and the human ear, the basics of broadcast audio processing, the basics of gain control, limiting and clipping, adjusting a wideband processor for voice and multi-band processing. The Society thanks SBE Member Stephen Poole, CBRE, AMD, CBNT for his work in developing this course. The cost is $80 for SBE Members and $105 for non-members.

SBE IRLP without a connection

by Jack Roland
How to participate in the SBE IRLP Hamnet
without a radio or IRLP connection near you

Greetings all, The next net is usually held at 11am Mountain, 1pm Eastern time, of course on the IRLP Reflector 9615 and now via Echolink at *SBE*, or node number 96150. IF you are radio-less, or have no IRLP node near you, now you can participate in the net, & get on the IRLP reflector anytime, all from your PC with Echolink.

Details on how to get on Echolink are at Simply download the software, install and go thru the registration process, they essentially just want to see your ham license (I scanned a copy of mine and emailed it to them). It is free and easy, although it will take a few days to get the confirmation back. Then, setup the software on your computer, they also have a great helpfile on how to deal with routers and firewalls, and then you can do a search for *SBE* or node number 96150, and you can connect that way. We even had an interested amateur from Moscow Russia check into the last net. All Amateurs and Broadcasters are welcome!
