The August 2000 Meeting

8-16-00 SBE/SMPTE meeting hosted by Burst Communications.

We want to express our appreciation to Kirk Basefsky at Burst for hosting and for the great lunch. Ron Vincent brought the meeting to order and discussed SBE's most recent financial statement analysis, and discussed the new Broadcast Networking Technologist certification. Reference was also made to upcoming SBE regional conventions and their listing at the SBE.org website. There was no business from the floor. Kirk Basefsky introduced the Leader representatives Tony Walker, Leader regional sales manager, and Joe Fisher, Leader Production Marketing Manager. Also featured was Hans-Christian Molstrand, Product Manager for ProTeleVision Technologies who has product being marketed by Leader. Joe Fisher discussed and demonstrated how their LV5152DA HDTV Digital WFM and LV5836B Surround Audio Monitor operated. The LV5152DA has many features - WFM, Vectorscope, Picture display and Stereo monitoring. This unit displays 14 different digital serial A & B input signal formats. Also discussed was Leader's LF982 signal level meter which measures signal levels for VHF/UHF/FM, digital and satellite operations. Weighs in at 4.4 lbs and is only 8 1/2 in. X 3 7/8 in. X 8 1/4 in. Great price too. Leader also had other equipment on display.

Hans-Christian Molstrand with ProTeleVision Technologies featured a "Compact Vari Time Sync Generator", model PT5201. This unit can provide simultaneously a dual standard, Pal/625 and NTSC/525. It will also allow timing of audio and video. The PT201 uses windows PC interface and in addition is an analog and SDI test signal generator with 24 different signals and a AES/EBU audio generator with digital test tones and also an analog generator. ProTeleVision Technologies is open to the wants and needs of the industry and welcomes your input. The PT5201 is very small(1/2 rack) and comes with a very impressive price. Thanks to Leader and ProTeleVision for their efforts.

Chairmans's corner : It is once more that time of year when opportunities to participate in SBE is welcomed. SBE chapter elections are offered in October/November. We wish to keep the October gathering informal, so if anyone is interested in filling a position or would like to nominate a person for an officer position, please advise either myself, Bill Harris or Fred Baumgartner. We will be open to nominations at the November meeting and we will conduct the elections at the November meeting as well.

Station Fined for Faulty Fence

The FCC has issued a Forfeiture Order to the licensee of WCVA (AM) in Virginia, a fine of $7,000 for failing to maintain an effective fence around the base of its station's antenna, and for failing to maintain transmitter power between 90% and 105% of that authorized for WCVA. An FCC field agent inspected the WCVA facilities and discovered that several vertical boards were missing from the fence enclosing the base of the station's antenna tower. This created a gap in the fence large enough to allow a person easy access to the tower. Additionally, the agent found that the hinges on the gate in the fence were not attached to the fence post, allowing the gate to be easily opened and providing easy access to the tower. In response, WCVA argued that the fine should be canceled or substantially reduced in light of it's long history of compliance with the Commission's rules and it's claim that the fence violation was not "willful" because the licensee was unaware of the breach in the fence. In recognition of WCVA's compliance history, the Columbia Field Office reduced the forfeiture for excessive power to $2,000.

Upon review, the Commission has generally agreed with the assessment made by it's Columbia Field Office. The agency said that licensee's conduct regarding the fence was willful, in that it knowingly failed to inspect it's property to assure itself that the fence was in good repair. The Commission found WCVA's lack of knowledge of the condition of it's fence troubling in view of the fact that the tower site is near an elementary school. Notwithstanding those shortcomings, the Commission did find that WCVA's good history of compliance with the agency's rules merited a $2,000 reduction of the fence forfeiture. WCVA's was fined $5,000 for the fence violation, and $2,000 for operating with excessive power.

Air Conditioning Considerations

How have you air conditioners been holding up in this meltdown heat? This has been a particularly bad year for cottonwood fuzz, and combined with multiple days over 100 degrees F it can only spell trouble if you haven't made extra checks or service. We lost a PA in our two way radio at the tower building after the circulation fan froze up in our air conditioner. Somehow, our security company failed to report the high temp alarm, costing us $700 for parts plus the service call for installation of a spare repeater we had purchased for such events. At our main facility, we lost the fan motor on a 5 ton AC condenser unit for our RF Headend. We limped along with a box fan laid on top of the unit while a new motor was located and installed. An air conditioner service man whose opinions I respect, once told me to wave my arm over the top of a condenser unit designed for top air discharge, and observe whether the air was exhausting straight up (desired) or seemed to be moving out at an angle. If the latter is the case, your condenser coils are likely stopped up and air is moving down from above near the center of the fan, then out in an angular discharge. Another thing I learned involved "split condenser coils." Two coils are nested together tightly, giving the appearance of a single unit. They appeared to be clean inside and out, but when the top of the unit was removed and the coils separated, they were found to be packed full in between, with little air getting through. Once washed out thoroughly, normal operation gradually resumed. Most of these items would not be covered by normal preventative maintenance, and only with the extra effort in the case of stopped up coils, could the breakdowns have been prevented.

Another situation that can develop in extreme weather is that of the power outage. If you have the luxury of a motor-generator, is it serviced and checked semiannually by a professional? Routine checks of coolant, oil, and fuel levels along with battery checks is something you can do, but it must be done regularly for reliable service when the unexpected happens. Have you checked with an amprobe at the transfer switch so you know how close to capacity you are running, and have you done this both with the air conditioner on an off? With the A/C off, you can convert the power to BTU's and then to tons of A/C required. You may be close to capacity on your air conditioner too! Don't forget that a motor generator may not be able to deliver the locked rotor amperage required to start a motor such as an air conditioner compressor. Sometimes a slow start kit installed on your A/C compressor by your serviceman can help with this problem. As equipment is added to a building (such as cellular repeaters, or other lease equipment) one or more of these problems can creep up on you over time. It might be worth your time to re-evalutate some of your remote sites, or sites you lease from someone else, to insure a better night's sleep for yourself during weather extremes.

A New Source Of RFI?

A new wireless Internet device that's being heavily marketed is KIMA from Akoo.com. See: http://www.akoo.com/site/products.cfm?CFID=1657313&CFTOKEN=303 71194. The device is said to "...wirelessly send internet audio and digital music from your PC to any stereo or portable radio system of your choice up to 1,000 ft. (away)" on 88.3 MHz. -Mike.E.Worrall@abc.com Mary Woodworth of KSDS, 88.3 MHz, San Diego, investigated Kima thanks to Mike's warning. She writes, "The transmitting unit will not cause interference to 88.3 FM signals. The transmitting unit operates in the 900 MHz range like many cordless phones. The RECEIVING unit does send the wireless signal to (an FM) radio using 88.3, but (the factory claims it is) at extremely low power." Mary has not been able to verify whether Kima has the necessary FCC approvals to allow marketing in the U.S., or whether the 88.3 signal is extremely low powered as the company claims. John Reed of the FCC writes, "Certified products will have a label on them with an FCC ID number displayed!" The 88.3 transmitter should only reach about 35 feet, like a wireless microphone. If anyone gets their hands on a Kima from Akoo, check it for an FCC ID number, then verify that number with the list at http://www.fcc.gov/oet/fccid. Also check the range of the 88.3 signal if an interference-free environment can be found.

Amateur Update

From Chapter 24
By Tom Weeden, WJ9H

As of Friday, September 1, every US amateur was required to fully comply with the FCC's RF exposure guidelines. The regulations, which went into effect January 1, 1998, require US amateur radio operators to read and understand the rules and, where necessary, perform technical evaluations to determine that their stations are compliant with the new regulations. Up until now, only hams who have had to file an amateur radio application with the FCC have had to certify compliance with the RF exposure rules. Now, all amateurs must comply. Under the regulations, an amateur station must not exceed the maximum permissible exposure limits for transmitter operation. MPEs are both frequency and power-dependent.

The San Francisco Chapter of the International Television Association has produced a 30-second TV public service announcement designed to assist the amateur community in recruiting more young people to the hobby. Copies of the TV spot are being made available to Amateur Radio clubs for distribution to local television outlets at nominal cost. Each year ITVA volunteers produce a public service announcement for a charitable or nonprofit organization. This year, they focused on Amateur Radio. ITVA President Ken Alan, K6PSI, said he'd been hearing about the need to recruit "new blood" into ham radio, "so I suggested it to the PSA committee, and everyone loved the idea." The spot steers clear of ham radio stereotypes and shows the hobby as "contemporary, high-tech and fun." A Quicktime movie of the PSA can be viewed at the ITVA Web site, http://www.itvasf.org.

The SBE has elevated amateur radio operator Fred Baumgartner, KG0KI, of Parker, Colorado, to a Fellow in the Society. Baumgartner, who's with the National Digital Television Center in Denver, has been a member of SBE for 27 years. SBE cites his "many valuable contributions to the advancement of broadcasting engineering and the Society of Broadcast Engineers." Baumgartner has authored more than 100 technical articles and several books including "Salvaging Waterlogged Gear" in the March 1999 issue of QST magazine.

Clay's Corner

Featuring News, Rumors and Views From Usually Reliable and Irrefutable Sources
By Clay Freinwald, Chapter 16

Have you followed the techno-action that's all directed toward the Car-Radio? For a long time the car radio was pretty much a captive audience that has been divided up among the local radio stations (that is, unless the driver wishes to listen to tapes or, perhaps, CD's). Well, this segment has caught the attention of many others. Coming this year will be the 'other' radio stations using satellites and local 'repeaters'. But watch out for the non-music guys. They are working on making sure that your car is also connected 'on-line'.

Another grand old call letter is biting the dust. The WMAQ call letters in Chicago are being retired, all a part of consolidation. That's where a number of significant figures in our industry got their start. Dave Garroway and John Chancellor, to name a couple.

Have you been following the 2 gig battle in L.A.? There, local law enforcement wants a chunk of spectrum for their own TV coverage. The land of helicopter drama has caused a lot of clenched teeth in the TV ENG and Amateur Radio world. Thanks to fellows like Dane Erickson, Chris Imlay, Bill Kelsey and others, our interests are getting the attention they need.

Received a call the other day from the manager of KARI in Blaine. Understand that they are going to build a second station, this time a 50 kW AM. He was looking for technical help in the form of a person who was familiar with the construction and operation of 50 kW AM plants. Whew... I could not come up with a name of a person with those qualifications that was looking for a job. He asked me how much he would have to pay for a full time engineer meeting those qualifications.... When I told him he explained that this was more than he was making. I asked him the classic question, like how much do you pay an hour for someone to come out and repair your copy machine or perhaps your computer network?

Charlie Brown called me the other day to announce that Vox Pro is back. Charlie, if you recall, was the morning man for years on Seattle's KUBE. He worked with some code writers to come up with what became a very popular DAW specifically designed for today's On-Air studios. Then the computer that the unit was based on, a MAC, became hard to find. Well, it's back and according to Charlie, better than ever, and uses the latest MACs. Nice to see a locally produced product do well. It's still sold by Harris.

Have a great one... and don't forget to empty the pan under the grid-leak. CUL, Clay

Styrofoam

From: Lynn Osburn <losburn@lewan.com>

Building #19, a retailer in the Boston, Massachusetts, area, has always offered their shoppers free coffee. Recently, they switched from styrofoam to paper cups. On the cups is this explanation:

Please Join Building #19 in our fight to save the endangered styrofoam.

Herds of these peaceful creatures once roamed the plains of America, but now their numbers have dwindled to a precious few due to Mankind's shortsighted harvesting of them for their white insulated pelts.

So remember, as your fingers burn while holding this paper cup, that you're helping, in a small way to make the world a safer place for the friendly styrofoams.
