Senate Approves Spending Billwith Broadcast Ownership Verbiage

Washington - Jan 22, 2004 - The Senate approved a $373 billion billto fund most federal agencies. The catch-all measure passed in a 65 to28 vote. The bill now goes to President Bush, who will sign it soon,according to Republicans.

Included in the bill is language that sets the national TV ownershipcap to 39 percent. While the FCC increased the limit to 45 percent inJune, a federal court has debated the issue. The 39 percent compromisewas established by lawmakers at the end of 2003.

The NAB is pleased with the bill's passage. NAB President Eddie Frittsreleased the following statement:

"We're pleased the national television ownership capissue appears to be resolved by the passage of this legislation. Wesalute all broadcasters who worked with Congress to reach thiscompromise that recognizes the enduring value of free, local televisionstations."

Jampro Investigates Nitrogen vs.Dry Air Debate

Sacramento, CA - Jan 21, 2004 - The use of desiccated air vs. theuse of nitrogen to pressurize transmission lines is seldom given muchattention beyond the ongoing costs of the desiccating equipment or thenitrogen bottle rental. But following some research by Dupont at theurging of Technical Broadcast Associates, Jampro has releasedinformation that endorses the use of dry air for chemicalreasons.

Pressurized transmission lines use Teflon insulators to maintain thespacing between the outer and inner conductors. When Teflon is heatedto 500� C, the carbon and fluorine atoms, normally bonded intoCF2 molecules, will become a double-bonded CF2molecule. This double bonded CF2 becomes CF3 (agas) and C (carbon, which is visible as soot).

The chemical result of CF2 + CF2 when heated withnitrogen yields HF + CF2O (carbonate fluoride) + C (carbon).Carbon inside the antenna and coax is not a favorable condition.

However, when CF2 + CF2 and dry air are heated,the result is HF + CF2O + CO2, a less damaginggas.

While dry air contains some nitrogen, the additional gases, notablyoxygen, modify the chemical reaction.

High heat in a coaxial cable can be caused by an electrical arc or alightning strike. During the arc, the heated air expands quickly andmay open the pop-off valve, which allows more air to move through thesystem. When dry air is used, more oxygen is provided to bond with theCF2, creating more CO2. Once the oxygen isdepleted, the resulting byproduct is carbon. Depending on the durationof the flash-over or arc some carbon will still form in the presence ofdry air, but not nearly as much as in the presence of nitrogen. Somecarbon will likely result whether nitrogen or dry air is used, butusing dry air should significantly reduce the amount of carbon duringthe reaction.

Jampro recommends that stations likely to experience lightning or thatuse transmitters capable of sustaining an arc for more than few secondsshould only use dry air, not nitrogen. Nitrogen can be used to testpressurization or to purge a line, but the nitrogen should also bepurged when the coaxial cable is put into regular service.

FCC's Powell Wants to Boost Finesfor Obscenities

Washington - Jan 16, 2004 - FCC Chairman Michael Powell last weekproposed a tenfold increase in the fines that can be imposed onbroadcasters for indecent programming. The current maximum levy is$27,500, which Powell termed as "peanuts" for large mediacompanies.

"They�re just a cost of doing business," Powell told a NationalPress Club luncheon. "That has to change."

Such a change would require congressional approval. It comes in anelection year amid conservative criticism of the FCC for a ruling lastOctober (an expletive uttered by the musician Bono on a network TVprogram was not indecent because it was used as an adjective ratherthan to describe a sex act).

Congress plans a hearing this month on broadcast indecency.Broadcasters are trying to compete with coarser cable programming andare targeting young men, who are coveted by advertisers and consideredless likely to be offended by explicit language.

Under FCC rules and federal law, terrestrial broadcasters cannot airobscene material at any time, and cannot air indecent material between6 a.m. and 10 p.m. The FCC defines obscene material as describingsexual conduct "in a patently offensive way" and lacking "seriousliterary, artistic, political or scientific value."

There are no such requirements for subscription TV channels, which donot use the public airwaves for transmission. Some critics say mediaconsolidation has contributed to the use of stronger language on theairwaves. They argue programming decisions increasingly are being madeby media company officials who have no connection to the communitiesthey serve.

Powell, however, argued that broadcasting has simply become morecompetitive. But rather than spawning better programming, "it�s arace to the bottom," he said.
