From The Chapter 48 Chairman

Ron Vincent

SBE Chair Comments:

As your new SBE chapter chairperson, I have quickly recognized the past and present officers and members commitments in time, talent and perseverance. I personally thank them and hope to continue these traits in my efforts. At present, we are pursuing the possibilities of doing the frequency coordination on the Web only. This will curtail some of the existing costs and hopefully be user friendly. More to come as this effort continues. Any suggestions will be appreciated. I encourage everyone to support the local SBE/SMPTE meetings. As already experienced, these meetings take a lot of effort to put together and are for advancing everyone’s knowledge in this ever-changing environment. Try to get your station management to support your efforts in attending these. We would like suggestions for future meetings. We wish to serve your needs in these meetings. Do you have a preference on meeting times - day or evenings? Let us know. Any of the officers can be reached by phone or e-mail. My e-mail is accessible via the SBE Chapter 48 home page. Local participation in the SBE certification at my facility has been on the rise and I have already noticed the pride that comes with such efforts along with the knowledge from the study time. I hope we can encourage like feelings throughout our area. Let me know if I can help. I look forward to meeting everyone in person as time allows. Thanks - Ron Vincent, CSTE, KWHD TV-53

The March 2000 Meeting

Summary by Rome Chelsi

AT&T's HDTV test facility hosted our March SBE/SMPTE meeting. It seems that at least once a season, bad weather comes into play. Those that were able to attend, found the presentation from TeraNex to be not only an equipment demonstration, but also a peek into how military applications are making it into Broadcast. TeraNex is a spin-off of Lockheed Martin imaging technology used by the US Military in high resolution mapping, targeting, and microscopy.

Randy Thomas and Steve Wong of TeraNex demonstrated their unique product which has the capability to accept SDI and ATSC formats and to up or down convert to the various ATSC formats. We were provided a discussion of de-interlacing techniques including motion compensation and a propriatary TeraNex pixel compensation algorithim. For additional information check out the TeraNex WEB site at: www.teranex.com.

Our thanks to Fred Baumgartner and the folks at AT&T for providing us with a first class demonstration area.

Hungry Engineers Find Food

Many hungry radio broadcast technical types converged on the Del Frisco steakhouse on Orchard Road in March to eat, drink and rub elbows with the folks from the Harris Corporation. At the invitation of Harris district sales manager, long time Denver area resident and Chapter 48 supporter Ken Perkins, a couple of dozen engineers and MIS people enjoyed each other's company and had a chance to put a face with the names Cam Eicher, Peter Acquaviva and Dennis Mackey. In addition to full stomachs, the attendees went away with a pocketful of business cards, a keychain-sized "Leatherman" style tool and the ever coveted extra long greenie screwdriver. Seen among the diners were representatives of Clear Channel Communications, AMFM Incorporated, Jefferson Pilot, Public Broadcasting Corporation of Colorado, Vir James consulting, Salem Broadcasting and the inimitable Mr. Oscar Cuellar.

Wireless Applications To Change

By Tom Smith, Chapter 24

As of April 1st, the FCC is accepting applications for certain microwave licenses by electronic means only. This is part of the introduction of the Universal Licensing System, a database system that allows for viewing of wireless license information on the internet. Applications will be able to be filed on the internet in the near future, with the system currently supporting a dial-up entry system. It will be mandatory to file applications electronically for common carrier services, local multipoint distribution services and 29 GHz market areas.

Broadcast Auxiliary licenses and private point to point may be filed manually, but the FCC would prefer electronic filing. As part of the transition to the new system, the FCC will no longer accept the following applications as of March 1st: Forms 313, 313R, 402R, 415, 415T, 430, 701, 702, 703 and 704. 313 and 313R were broadcast auxiliary forms. All users must use forms 601 and 603 where appropriate. Manual applications must use the version of form 601 issued after August 1999, and form 603 issued after February 1999. Before filing any application for a broadcast auxiliary license, read the notices from the wireless bureau on the new licensing. Notices were released on February 4th (DA 00-27) and 18th (DA 00-317) with instructions on the changes, including how to use the phone system on the February 4th notice. You will also need a certification number from the local frequency coordinator when filing the application. This is a new method of handling all wireless applications, so don't be suprised if you have some problems. There is much discussion of the changes among the SBE frequency coordinators including the use of the different forms. Checking with an attorney or consultant may also be helpful.

SBE Introduces Certified Broadcast Networking Technologist

SBE has rolled out a new certification program designed to respond to the convergence of the broadcast and information technology fields. Applications are now being accepted to take an exam to become a SBE Certified Broadcast Network Technologist. Terry Baun, CPBE, SBE National Certification Chairman, explains that the new certification level will delve into networks as much as possible without becoming specific to any vendor. Topics covered by the exams will include the basics of broadcast local area network installation, recognizing what a hub is, knowing what the different wire categories do and understanding the basic layers of network protocol common to all systems.

Amateur Radio News

By Tom Weeden, WJ9H

Hams who will be eligible for higher-class licenses as a result of the FCC's recent restructuring of the amateur radio service are scrambling to take advantage of the upcoming April 15th rules change. The FCC action, reducing the number of license classes to three and establishing 5 words per minute as the sole Morse code examination element, has caused a brisk demand for study materials. On April 15th, hams who had previously passed a higher class written exam within the last year but had not passed the higher code speed test will become eligible for the higher class license due to the relaxed code speed requirement. Here in Madison there will likely be more people lined up to take written exams at the monthly sessions in March and April. A special "no exam" session will also take place locally on April 16th for those eligible hams to fill out their paperwork and obtain their higher class license.

On March 1st, the FCC began accepting requests from amateur radio organizations interested in becoming club call sign administrators. Organizations which meet FCC requirements will be authorized to process applications from ham clubs or military recreation stations seeking their own call signs. This delegation of authority to volunteers in the private sector is similar to the commission's creation of the volunteer examiner program several years ago.

A Mississippi ham arrested for interfering with his neighbor's telephones is off the hook. Bennie Stewart, KJ6TY, was arrested and charged last September under a Mississippi law making it illegal to interrupt telephone communications. Stewart asked the court to throw out the complaint on the grounds that only the FCC had jurisdiction. The court tabled the criminal action, saying it had jurisdiction over the subject criminal matters, but that the state court's jurisdiction had been preempted by federal law.

NoIsE frOm aLL Over!

From Chapter 3

The FCC announced February 4th, it was denying Sinclair Broadcast Group's Petition for Expedited Rule making requesting the Commission modify its DTV rules to allow broadcasters to use COFDM modulation in addition to the 8-VSB modulation standard. They concluded that the benefits of changing the DTV transmission standard to COFDM would not outweigh the costs of making such a revision, and that NTSC replication is attainable under the 8-VSB standard. Industry comments were heard soon after, endorsing the FCC position, but this in no way has deterred Sinclair. They soon plan to demonstrate the problem to Congress. Many members of Congress have made it clear they expect over-the-air digital television to be received without reliance on cable, satellite or expensive, outdoor directional antennas. Sinclair's position is that most indoor DTV reception does not equal the quality of NTSC reception under similar conditions. It is reported that other major interests are beginning to question the wisdom of the FCC's stance. NBC/GE has performed independent tests confirming the Sinclair assertion. Stay tuned!

Comsearch has opened a new office in Denver in response to the increased demand for more services in the wireless arena. It is to be manned by Douglas Erbeck, formerly with Western Telecommunications, Inc. for 28 years. Doug can be contacted at (303) 400-4056, or by e-mail at derbeck@comsearch.com.

While waiting for a couple of pilots at Yingling Aircraft recently, I noticed a new type of flashlight. Rather than a miniature Krypton bulb, this one (2 AA size) had four white LED's. It was touted as very reliable, and sold for about $20.

Speaking of "what ever happened to .........?", how about the ruckus caused a couple of years ago, when alleged interference to biomedical devices in several health care facilities were said to have occurred due to the commencement of DTV transmissions at the WFAA-DT television station in Dallas? I don't know that I ever heard a resolution of this problem, although I would be surprised if the hospitals didn't upgrade their equipment to improve shielding and/or move to frequencies licensed for that purpose. As I recall, they had made use of low power transmitters allowed under FCC Part 15 Rules on a frequency assigned to WFAA-DT. The receivers displayed less than favorable conditions of heart patients to which the monitoring transmitters were attached when WFAA-DT first fired up for on air testing.

Gary Krohe has contributed a few lines that apply to the "what ever happened to" theme, or perhaps more correctly, "you know you've been a TV engineer too long if ...."

1.) You have actually changed a vidicon or image orthicon tube and know it doesn't go in a transmitter;

2.) When you hear the word `Multiplexer' you think of a film chain, not someone who hangs out at the local movie mall;

3) You know what a film chain is;

4.) You know a Dynode spot isn't a location for some sort of dual directional connection on the office LAN;

5.) When you hear the network is down, you think of grabbing a reel of fill film, and not of rebooting the server;

6.) You needed an FCC First Class Radio Telephone License to work in Engineering, and you had one;

7.) You know what the `30' at the end of this article means and how it originated!

Clay's Corner

By Clay Freinwald
Chapter 16, Seattle

The LPFM issue is certainly the source of a lot of dialog and discussion with many full-size broadcasters very unhappy over this decision. NAB is working hard in their opposition of this whole thing, taking their battle to the Congress. I remember making comments a while back in this column to the effect that if enough pirate broadcasters went on the air the FCC would likely enact new rules that would make this type of operation legal. Seems a bit funny that petitions for rule making to permit this were turned down over the years, yet when enough folks break the law the matter is given more serious attention. I wonder if this would work the same for HOV lanes? If enough people just starting using them would the state patrol grow tired of enforcing the law to the extent that they would rewrite their rules?

Remember Scala, the little Oregon maker of great antennas? Well, the product is much the same, but the name has been changed. It's now Kathrein, another name from Europe that's been around a long time. On the subject of Antennas, we are sad to report the passing of Jim Larsen, K7GE. Jim was the founder of Larsen Electronics in the Vancouver (Wa) area many years ago. Not only did the name Larsen become a household name with many hams, but through his products sold to the Land Mobile and Public Safety industry.

WAGG in Birmingham will pay the FCC. The infraction? Broadcasting a phone call without FIRST advising the party that they would be on the air. This rule has been around as long as I have and yet the FCC continues to find those that either have never heard of it or, figured that if enough violated the rules the rule would be changed.

On January 10 the FCC announced that they were going to establish "minimum" telephone inside wiring quality standards to promote consumer access to existing and advanced telecommunications services. These new rules require the installation of solid 24 gauge (or thicker) twisted pairs, marked to show compliance with Cat 3. Now let me say, as a person who deals with consumer complaints of interference to EXISTING telephone equipment from AM and FM transmission equipment, WHY in the world did the FCC stop at Cat 3? Why not go to Cat 5 and provide some rules that required adequate grounding while they were at it?

Yes, EAS is alive and well and progress continues to be made toward getting the vision of those that created this system fully realized. On the National level I have been appointed to chair the SBE's EAS Committee. There are a lot of states that are still struggling with EAS; my goal is to have SBE provide the mechanism that will enable those that have yet to get EAS to really work for their area to really make the system work.
