Hope yours was satisfying, allowing time for a bit of re-acquaintance with family and friends. Without Holidays, when would we ever see those people anyway. Time to shake it off and get into the plans and goals for the year. Among the things to remember in your planning, are the methods by which you will keep yourself knowledgeable in the tools of the career you carry on for you and your employer. The best way to do that is to attend at least one of the many conferences this year. The first is the NAB, a few short months away, April 9 through the 13th in Las Vegas. Under the agreement with the NAB, the SBE will be conducting the Engineering conference at the show. In addition, here is the schedule of SBE events at the NAB: The Board will meet on Sunday, April 9, 8:00AM to 12:00 noon The Certification Committee will meet April 9, 6:00 PM to 10:00 PM Certification exams will be offered on the morning of Tuesday, April 11 The Chapter Chairs will meet 4:00 PM to 4:45 PM Tuesday the 11th The Membership Meeting will also be on Tuesday the 11th 5:15 PM to 6:00 PM The Engineering Luncheon will be on Wednesday with Lewis Platt, CEO of Hewlett-Packard. Of course, all these events are open to all SBE members. Make your plans early. Reservations at one of the official NAB hotels can now be made by calling: (800) 890-6227. As a Board member and your National Liaison, I am your link to any National person or committee. The most effective way to handle concerns needing a National audience, is by presenting them at a Board or Executive Committee meeting. The next such meeting will be that of the Executive Committee set in Dallas on Saturday, February 4. In order to get an item on the meeting agenda, you will need to contact me soon. The National Liaison Committee has recently filed reply comments to FCC Docket 94-32; Transferring of Below 5 GHZ Federal Government Spectrum to Private Sector Use. I have a copy of the filing. If you would like to read it, contact me and I will send you a copy. Closer to home, I must pass along the concern for the future of the Broadcast Clinic. Recently, the University informed Don Borchert that it will no longer support the Broadcast Clinic as part of its continuing education curriculum. Budget reductions were sighted as the cause. Discussions between parties will be held soon to decide what can be done to continue this excellent educational opportunity to Broadcast Engineers in the Midwest. Contact me with any suggestions you might have. I'll keep you informed on any progress. See you at the January meeting. It's been a while since weve looked at a Radio Station. It should be fun!! CHAPTER 24 DECEMBER BUSINESS MEETING MINUTES 12/13/94 Chapter 24 of the Society of Broadcast Engineers met in the new offices of the Dane County Emergency Management agency. The meeting was called to order at 7:10 PM by Chapter President Leonard Charles. The minutes of the previous meeting were approved as published in the Chapter 24 December newsletter. In the absence of the Treasurer, Leonard reported the Chapter financial balance indicating we are in the black. Chapter 24 membership now stands at 71, with a welcome to John Salzwedel, our newest member. Sustaining membership stands at 25. Steve Zimmerman represented the Program Committee, and reminded the members that next month the scheduled meeting is at the new studios of WTDY/WMGN/WJJO on January 19th. The February meeting date is still uncertain as Dennis Behr is trying to coordinate with BTS on a date for them to demonstrate their Media Pool video server system. Certification Chairman Jim Hermanson re-iterated the information from his newsletter article in December, with the reminder that the reduced price on the TV operators study guides expires at the end of December. He also reminded the members that he has certification materials for all levels available. Frequency Coordination Chairman Tom Smith reported no new activity this month, and indicated that he knew of no problems on election night which was a busy one on the broadcast auxiliary spectrum. Leonard reported a couple of items of news from the SBE National. First of all, they have sent a mailing to all of the members with a copy of the latest by-laws, and brochures for the SBE Group Insurance plans. Secondly, Leonard announced that he has been selected as National Liaison for Chapter 24, so any concerns which need to be shared with the National board should be directed to him. Then Leonard announced that he had received a letter from Don Borchert regarding the future of the Broadcasters Clinic. The letter stated that the University of Wisconsin had decided to discontinue support for the Clinic, due primarily to financial concerns. The letter indicated this came as a surprise to Don. He is exploring ways to keep the Clinic going without the participation of the University. Don has asked the members to contact him if they have any ideas or suggestions regarding the future of the Clinic. There was no old business or new business to be discussed. There were no personal or professional announcements, or general announcements. There were also no technical tips or discoveries shared. Leonard asked that anyone having information on aftermarket automotive receivers with AM Stereo please share the information with him, as there doesn't seem to be a comprehensive up-to-date list available at this time. The business meeting was dismissed at 7:24, and Steve Zimmerman introduced the program for the evening. Kathy Brenholt and Jim Engeseth of the Dane County Emergency Management Agency described the agency's new facility in the Dane County Public Safety building, and Jim gave us a tour of the communications facilities. Respectfully submitted, Mark W. Croom, Secretary AMATEUR RADIO NEWS by Tom Weeden, WJ9H An FCC ruling known as PRB-1, which pre-empts overly restrictive local antenna regulations, could be codified into law in Wisconsin if some area hams have their way. Several Wisconsin radio amateurs have contacted their state senators and representatives to urge them to draw up legislation giving the FCC authority to overturn zoning restrictions against towers in residential areas. In Connecticut, a US District Judge has ruled in favor of an amateur who was denied a permit to install a 78- foot tower by his town's planning and zoning commission. The judge cited PRB-1 and said, I think federal law is on the side of ham radio operators in this case. Two more astronauts, Mission Specialist Wendy Lawrence and Payload Specialist Sam Durrance, have become amateur radio operators. Lawrence, KC5KII, and Durrance, N3TQA, are scheduled to fly on space shuttle mission STS-67 in late February or early March. One of the newly-elected Republicans in the House of Representatives is a long-time amateur radio operator. David Funderburk, K4TPJ, represents North Carolina's 2nd District and fills the seat of a retiring Democrat. Licensed since 1959, Funderburk had taught history for 14 years in several North Carolina colleges and was appointed ambassador to Romania in 1986. The FCC authorization act that would have converted an annual regulatory fee for Amateur Radio vanity call signs to a one-time application fee failed to pass in the last session of Congress. HR 4522 passed the House but failed in the Senate. Broadcasting and Cable magazine attributed the defeat to opposition by the NAB to unrelated provisions in the bill. The FCC is now expected to introduce a vanity call sign program with a $70 fee, renewable every 10 years. Excerpts from January 1995 Badger State Smoke Signals and QST magazines FCC PROPOSES UNATTENDED OPERATION By Tom Smith The FCC has started an inquiry into changing the operator rules for transmitters to allow for unattended operation. The commission believes that with the monitoring and control equipment that is available today some or all stations may not need the continuous monitoring of a duty operator. Stations would still be required to maintain operation within FCC rules and to have equipment that would monitor and cease operation in the event of a malfunction that would cause interference. The FCC is also seeking comments on the need for licensing of duty operators if a station would like to retain them. Congress amended the Communication Act in 1992 and removed the requirement for licensed operators. This act and the new EBS rules are the reason it is now possible for the FCC to look at the possible changes in the operator rules. This inquiry covers radio, TV and LPTV. The docket number is MM Docket No. 94-130 and was adopted by the FCC on November 10, 1994 and released on December 7, 1994. Comments are due on January 20, 1995 and replies are due on February 6, 1995. From RADIO WORLD, TELEVISION BROADCAST and FCC PUBLIC NOTICE. ANALOG STILL REIGNS IN CABLE FOR AWHILE By Tom Smith General Instruments announced a new series of advanced analog cable converters. GI previously announced delays in their anticipated compressed digital video converters. The delays are caused in part by the setting of the MPEG-2 standard in November and the complexity of the digital systems. The digital boxes are still in the lab and GI has not started manufacturing. Volume deliveries are not expected until late 1995 or early 1996. A number of cable companies including TCI have ordered the GI digital converters for channel expansion upgrades. GI expects that digital video penetration will only be 10% by mid 1997. Because of the slow deployment of the new digital systems many cable companies are in the need for an advanced box that will operate with analog signals. This is to enable them to offer new services at the present time. GI has claimed that they have orders for over 2 million of the advanced converters. There are over 1.6 million digital boxes on order.

Edited by Paul Stoffel TECH TIPS--CAPTURING AN INTERMITTENT by Dan Maney of Maney_Logic The problem... Occasionally WKOW's Odetics TCS2000 spot playback systems BVW-10's and 40's will que to the wrong place on the tape without warning. The RS422 control command Cue up with data allows the system to specify a desired timecode and the deck takes care of cueing to that point. The system then polls for completion and assumes the deck cued correctly. During times of inability to read correct timecode the decks just interpolate their timecode using the dependable control track. This works fine when interpolating from a correct timecode starting point, but fails when the last good timecode is from the previously ejected tape. The Need... Capture the sequence of events leading up to the error so that the problem can be studied in detail. Also, until a solution is found, provide a warning alarm so the operator can correct it before air. The Concept... Install a tiny bug (custom IC) attached to the suspect board's test points of interest. Transmit continually to a PC, which provides on screen display, operator warning alarm, and logging to disk in a compact easily readable form. The BUG... I programmed the 16C54LP Micro Controller (uC) to sample eight digital test points 60 times a second and continually transmit the data at 1200 baud N,8,1. With no serial port, the uC assembly language code is mostly serial transmit routines. The 18 pin Dip, crystal & capacitors fit on a tiny PC board barely bigger than the chip itself. The bug gets +5 volts & Ground from the suspect board, and is wired to eight test points. The test points of interest were all 5v/0v and could be directly connected to the uC pins. By adding an opto isolator inside the DB9 connector at the PC, there is no physical connection between the PC and the Bug. The PC... Quickbasic was used for the PC programming. This is where a custom screen was created to show easy to see NAMED testpoints and activity. As we learn more about what is happening with the timecode board, basic code can be written to alert the operator under specific conditions. The program was written to only log to disk when the test points changed, adding time and date stamps when needed. The log file is a simple ascii text file with the following format. The eight names are the names chosen for the test points. Slow Med Fast BER DER TCT interp down 18:34:56 12/25/94 (etc) Now if it happens again, we can learn from it. (Who said our work shouldn't be fun?) Dan Maney Maney-logic 608-277-8001 OWNERSHIP LIMITS TO CHANGE By Tom Smith The FCC has been looking at the number of stations that broadcasters can own. In September, the FCC raised the number of radio stations one company can own from 18 AM's and 18 FM's to 20 of each type of station. For minority held groups the number was increased to 25 of each type of station. The FCC is now looking at raising the number of TV stations that one group could own. The current limit is 12 with minority groups allow 14. These 12 stations cannot reach more than 25% of the national audience. That means that groups in the largest markets may be limited to less than 12. The FCC has proposed a number of chances in the TV ownership rules in mid-December. The changes include the lifting of the 12 station limit and raising the cap on audience reach from 25% to 50% of TV homes. The cap would be raise by 5% every 5 years till the 50% limit is reached. With the lifting of the limit on the number of stations that a group could own and a 50% audience limit, the number of stations owned by any one group could vary greatly. For a group owning stations in the nations largest markets the limit would by about 25 stations. For groups in the smallest markets the limit would be 180 to 190 stations before they would reach 50% of the audience. There are over 210 markets in the country. Other possible changes in the ownership rules included lifting the ban on owning both radio and TV stations in the same market. That ban was imposed in the 1970's. The FCC would also create rules covering local marketing agreements between TV stations, the current rules only cover radio. The ban against owning two TV stations in the same market may be relaxed allowing for duopolies in television as is now allowed in radio. The FCC is also looking at raising the percent of ownership of a station that becomes attributable against ownership limits. This rule allows banks and investment firms to make loans, hold mortgages and other stock investments in a number of stations without it counting against any of the broadcast groups ownership limits that the investments are held in. This allows a money market group to buy shares in GE, CBS, Cap Cities/ABC etc. without limiting this company's ownership limits. The FCC is considering raising the ownership limits from 5% to 10% for voting stock and 10% to 20% for non-voting stock. The rule changes on attribution is being investigated by FOX's non-attributable ownership investment in some of their affiliates such as New World Communications, Savoy/Fox and Fox/Blackstar. ABC has similar agreements with Young Broadcasting and CBS with Group W. The FCC is investigating if these investments are being used to bend the ownership rules. NBC has contested the sale of WLUK in Green Bay on the grounds that the ownership rules are being violated. From BROADCASTING&CABLE THE BIG SWAP By Tom Smith The big network swap in Milwaukee was finally completed on December 11. WITI, channel 6, which had been with CBS, became a FOX affiliate. WDJT, channel 58, formally an independent, joined the CBS network. WCGV, channel 24, which had been the FOX station, will join the new United Paramount Network. The announcement that WDJT would join the CBS network occurred on December 6. Last May New World Communications Inc., owners of WITI, announced that all the stations they owned or were acquiring are joining the FOX network. All 5 of the stations it owned at the time were CBS affiliates. The stations they were buying were affiliated with CBS, NBC or ABC. FOX also invested $500 million into New World as part of the deal. Besides being a station owner, New World is also a program syndicator There had been much speculation about who would become the CBS affiliate in Milwaukee until the December 11 announcement. CBS had approached a number of stations unsuccessfully including NBC affiliate WTMJ and ABC affiliate WISN. Both stations signed long term agreements with their existing networks. Also WCVY, channel 30, a religious station and WJJA, channel 49 (Racine/Oak Creek), affiliated with the Home Shopping Network, were also approached. According to BROADCASTING and CABLE magazine, WCVY was offered a $10 million offer to sell the station to CBS which they rejected as too low and not in the best interest of their viewers. The changes at both WITI and WDJT will have an impact on local programming in Milwaukee. WITI has expanded their news staff by over 3 dozen people. This includes both news and technical support people. They are now airing 7.5 hours of live programming on weekdays. WDJT will start a local news operation sometime this year. They are also continuing to look for a site to build a new 1000 foot tower. WDJT currently broadcasts from a tower on the MARC PLAZA hotel in downtown Milwaukee. WDJT's antenna on the MARC PLAZA is only about 550 feet above average terrain. That site was previously used by WVTV, channel 18, before they moved to the tower they now share with public television stations WMVS/WMVT. Also WDJT is on many different channels on the various cable systems in the Milwaukee area. As a side note, the owners of WDJT, Weigel Broadcasting lost their affiliation with the Spanish language network UNIVISION on their station in Chicago, WCIU channel 26. UNIVISION recently bought WGBO, channel 66, and moved their programming to channel 66. WCIU is changing their programming to that of a regular independent and investing $5 million in a 64,000 square foot all digital plant.
