The FCC also denied several petitions for rule making aimed at altering portions of the Amateur Radio regulatory landscape and ordered minor changes in Part 97. The NPRM is a result of a dozen petitions for rule making, some filed more than a year ago and a few dating back as far as 2001. Comments on the proposals put forth in WT Docket 04-140 are due by Tuesday, June 15, with reply comments by Wednesday, June 30. Among other changes, the FCC has recommended adopting the ARRL's "Novice refarming" plan <http://www.arrl.org/announce/regulatory/refarm/>. "Because the ARRL petition addresses the operating privileges of all classes of licensees on these Amateur Service bands, we believe that the ARRL petition provides a basis for a comprehensive restructuring of operating privileges," the FCC said in its NPRM. "We note that, as proposed, no licensees would lose any spectrum privileges and that General, Advanced, and Amateur Extra Class licensees would gain spectrum for phone emissions, one of the most popular operating modes on the HF bands." The ARRL referenced its Novice refarming proposal in its recent Petition for Rule Making, RM-10867 <http://gullfoss2.fcc.gov/prod/ecfs/retrieve.cgi?native_or_pdf=pdf&id_docu ment=6516083735>, which, along with three other petitions (see "FCC Invites Comments on Amateur Radio Restructuring Plans," <http://www.arrl.org/news/stories/2004/03/24/2/>) remains open for comment until April 23. The FCC also has proposed essentially eliminating its rules prohibiting manufacture or marketing of Amateur Radio Service power amplifiers capable of operating between 24 and 35 MHz. Originally put on the books in 1978 to keep high-powered amateur amplifiers out of the hands of CBers, the rules now "impose unnecessary restrictions on manufacturers of Amateur Radio equipment and are inconsistent with the experimental nature of the Amateur Service," the FCC said. The FCC additionally proposed a rule change that would make Kenwood's Sky Command system legal for operation within the US. The proposed amendment to §97.201(b) of the rules would permit auxiliary operation on 2 meters above 144.5 MHz--with the exception of the satellite subband 145.8 to 146.0 MHz--in addition to frequency segments already authorized. The Sky Command system permits the user to operate certain Kenwood equipment remotely via a VHF/UHF handheld transceiver. In response to an ARRL petition, the FCC proposed extending the bands available for spread spectrum experimentation and use to include 222-225 MHz. On its own initiative, it also recommended including 6 and 2 meters as well. Current rules limit SS emissions to frequencies above 420 MHz. Among other changes, the FCC also proposed to prohibit acceptance of more than one application per applicant per vanity call sign; permit retransmission of communications between a manned spacecraft and its associated Earth stations, including the International Space Station; allow current amateurs to designate a specific Amateur Radio club to acquire their call sign in memoriam; eliminate §97.509(a) of the rules, which requires a public announcement of volunteer examiner test locations and times; and add to §97.505(a) to provide Element 1 (5 WPM Morse) credit to any applicant holding a Technician license granted after February 14, 1991, and who can document having passed a telegraphy examination element. The Commission ordered some changes in Part 97 without requesting comment. It ordered, among others, the revision of the definition of an "amateur operator" in §97.3(a)(1) to reflect that entry in the FCC Universal Licensing System (ULS), not a license document, determines whether a person is an Amateur Radio operator. The FCC also adopted a technical change--in line with a recent amendment to the international Radio Regulations--to specify that the mean power of any spurious emission from a new amateur station transmitter or amplifier operating below 30 MHz be at least 43 dB below the mean power of the fundamental emission, 3 dB greater than the current requirement. The FCC turned down a petition would have established distinct CW and phone segments in the 160-meter band. Although a majority of commenters supported the proposal, the Commission said the current voluntary band plan "adequately accommodates the operating interests of all licensees who use the 160-meter band because it was based on input from those who use this spectrum." Among several others, the FCC turned down petitions that would have imposed restrictions on the time, length or transmission frequencies of bulletins or informational transmissions directed at the amateur community. Also denied was an ARRL request to add to the special event call sign system certain call sign blocks that designate territories and possessions that have no specified mailing addresses. The FCC suggested using self-assigned indicators instead. The FCC Notice of Proposed Rule Making <http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-04-79A1.doc> in WT Docket 04-140 is available on the FCC Web site. As soon as the document has been posted, comments on the NPRM may be filed via the FCC Electronic Comment Filing System (ECFS) <http://www.fcc.gov/cgb/ecfs/>. Click on "Submit a filing."

In either case enter the NPRM number in the "Proceeding" field as "04-140" (without the quotation marks). ==>ARRL REQUESTS FILING DEADLINE EXTENSION IN BPL PROCEEDING The ARRL has asked the FCC to extend the deadline for comments and reply comments by 45 days in the Broadband over Power Line (BPL) Notice of Proposed Rule Making (NPRM) in ET Docket 04-37. Comments now are due by May 3 and reply comments by June 1. Although the FCC does not routinely grant such time extensions, the League said it wants to allow time for the National Telecommunications and Information Administration (NTIA) <http://www.ntia.doc.gov/> to conclude its study at BPL field trial locations. The ARRL said it anticipates the NTIA study to go public very soon, allowing only a couple of weeks at best to evaluate its conclusions and incorporate them into comments in the proceeding. "This proceeding stands to have a profound effect on the Amateur Radio Service, and a full and complete opportunity to evaluate the results of the NTIA study is critical to the ability of ARRL to respond in a meaningful manner to the proposals in the instant Notice," ARRL said in filing its request April 9. "At the same time, there is no need for any rush to judgment in this proceeding, since BPL trial sites are only now commencing operation." If the FCC okays the request, the comment date would move to June 14, and the reply comment deadline would become July 16. Granting the request, the ARRL contended, "will have no adverse effect on any interested party to this proceeding." The League said the new deadlines would provide everyone with approximately 60 days to review and evaluate the NTIA's study before having to file comments. "Should the NTIA report be substantially delayed in its public release, ARRL reserves the right to request additional time as necessary," the League said. Earlier this year, FCC Chairman Michael Powell turned down a request by US Rep Greg Walden, W7EQI (ex-WB7OCE), who--as a member of the House Subcommittee on Telecommunications and the Internet--had asked the chairman to delay further action on the BPL proceeding until the NTIA study had been completed and stakeholders had had a chance to evaluate it before commenting. Powell assured Walden February 3 that the FCC would give "thorough consideration" to all BPL studies before it takes any final action in the proceeding.

But problems persist, and the process is far from quick and simple, says ARRL North Carolina PIO Gary Pearce, KN4AQ, who has been among local amateurs closely monitoring the Progress Energy/Amperion BPL trial. Their experiences could indicate what amateurs may face in areas where BPL is widely deployed. "The mitigation process at this iteration of Amperion's hardware is neither simple nor precise," Pearce said earlier this month. Progress Energy/Amperion essentially are attempting to "notch out" or completely avoid ham radio frequencies, since hams have been the only HF users so far to file interference complaints. Complicating the effort, he says, is that the process is largely hit or miss, requiring field monitoring and feedback and sometimes another attempt to nail the target. Pearce says he and Wake County ARES Emergency Coordinator Tom Brown, N4TAB--an engineer with extensive RF experience--met the week of April 5 with Progress Energy network engineer Bill Godwin at the so-called Phase II BPL trial areas to review the BPL spectrum in use. Amateurs also monitored the system using an Amateur Radio mobile station some 75 feet from the line. "Bill Godwin had a chart showing where BPL could operate and avoid ham bands, and Amperion had adjusted its system to comply with that chart," Pearce said. Among other issues, Amperion missed the mark on 20 meters--starting a BPL signal block on 14.300 MHz instead of 14.350 MHz, he pointed out. Pearce attributed the problem to a likely error in calculating the spectrum needed. BPL spectrum block edges "are not brick walls," he said, but taper off, with progressively weaker carriers remaining audible up to 100 kHz away, depending on the noise floor. "The remaining signals are very weak but would bother a home station within a city block or two of the power line." The goal is to be able to place BPL on a line in the immediate vicinity of a ham. Unclear at this stage is whether the "notching" scheme will work in a more-dense BPL environment. "More spectrum can be used below 7 and above 30 MHz, but Amperion prefers to remain between 7 and 30 MHz," Pearce said. "If this spectrum can be rotated between line segments, and the notches can be deepened some, they may satisfy the concerns of hams for the Amateur Radio spectrum." But, he adds, no efforts are under way to avoid other shortwave frequencies. "We appreciate this proactive attempt," Pearce said. "We will point out again that there are other public uses and users of the spectrum in between the ham bands." Amateur Radio operators "cannot sit back and say, 'Well, our problem's solved. Good luck with yours!'" Pearce says. He says that for this reason alone, the North Carolina amateurs still consider BPL a flawed concept. And, while he credits Progress Energy and Amperion with cooperating to resolve amateur interference issues piecemeal, "we just want to make sure that everyone understands where the goal line stands." ==>ARISS TO MULL HAM RADIO'S ROLE IN DISTANT SPACE TRAVEL The Elser-Mathes Cup, sitting idle for more than 75 years, is intended to mark the occasion of the first two-way Amateur Radio contact between Earth and Mars. That day may be moving closer. The Amateur Radio on the International Space Station (ARISS) International Team will contemplate ham radio's role as NASA--in response to a recent presidential initiative--seeks to expand the horizons of human spaceflight to the moon, Mars and beyond. During an International Team meeting March 25-26 in the Netherlands, ARISS International Chairman Frank Bauer, KA3HDO, said NASA's Education Office has asked ARISS to consider endorsing the initiative and start laying some groundwork for an Amateur Radio presence. That makes perfect sense to ARISS Secretary-Treasurer Rosalie White, K1STO, of ARRL. "Our space agencies are going to Mars now, so it's natural we should think about it and do initial planning now," said White, who was among the more than two dozen ARISS delegates on hand at the European Space Research and Technology Center in Noordwijk. "We could start by targeting our educational materials on exploration beyond the International Space Station." The ISS--the home of the first permanent Amateur Radio station in space--is scheduled for completion in 2010 using the space shuttle fleet, which then would be mothballed. Some ideas Bauer floated during the gathering included an Amateur Radio payload on the Red Planet as well as a Mars telecommunications satellite, remotely controlled Amateur TV and a repeater on the moon. The long-range planning will get further discussion when the ARISS International Team meets again in October. In other matters, the ARISS team learned that a planned slow-scan television (SSTV) system will not launch to the ISS this year. With just two crew members aboard the space station and a need to make the most use of space aboard Russian Progress supply rockets, NASA has suggested that ARISS hold up the SSTV payload for a Progress rocket flight closer to the space shuttle's return to flight, when the ISS again will have a crew of three. The two-person crews have not had much time to install and test ARISS projects, including the Phase II gear put into place earlier this year. While it's on the air for RS0ISS packet operations, the Phase II gear will not see routine FM voice use for school group contacts and casual QSOs until it gets a full on-the-air checkout. The SSTV gear needs additional preflight testing as well as work on the associated software. AMSAT-Russia's Karen Tadevosyan, RA3APW, is completing modifications to a Yaesu FT-100 HF/VHF/UHF transceiver. That equipment could go up to the ISS on a Progress rocket flight this fall. Other projects still in the discussion stage include an external digital ATV transponder and beacon. ARISS also is considering a project to use Amateur Radio via IRLP and/or EchoLink to link to the ISS via the Internet. The ISS could gain a third ham station once the European Space Agency's Columbus module goes into space. Through-hull fittings, or "feedthroughs," are being installed for as many as eight coaxial cable runs, although funding remains an issue. The feedthroughs would permit the module to accommodate UHF, L and S-band operations possibly using patch-type antennas being designed by ARISS volunteers. ARISS delegates also recognized the achievements and contributions of Roy Neal, K6DUE (SK), toward making the ARISS program a reality. Neal, a former NBC News science correspondent and executive, died last August 15. ==>IOWA AMATEUR GETS BACK LOST, REASSIGNED CALL SIGN The Easter Bunny was generous to Bill Sorsby of Cedar Rapids, Iowa. Earlier this week, the FCC finally made official the reassignment to him of N5BU, the call sign he'd lost in 2001 as a result of what the FCC has termed "filing errors" in its Universal Licensing System (ULS) <http://wireless.fcc.gov/uls/>. Not only did the FCC erroneously cancel the ARRL member's call sign, it compounded the mistake by reassigning it two years later to another amateur. When Sorsby realized some four months ago that his ticket was gone, he immediately contacted the FCC to find out what had happened and to get it back. "I am glad to see that the FCC has acted," said Sorsby, who's held N5BU since 1976. As the FCC tells it, in December 1999 it received requests to modify the contact information for the amateur license from Sorsby to Dwana C. Peters of Aircraft Guaranty Title (AGT), the title holder of an aircraft with the call sign 5BU. In the process, AGT also inadvertently also associated its FCC Registration Number (FRN) with Sorsby's N5BU Amateur Radio Service license. "This appears to have resulted from confusion between the aircraft station call sign and the aircraft's registration marking (or 'N number')," the FCC said in an April 5 Order restoring N5BU to Sorsby. In July 2001, the aircraft was sold, and AGT had the FCC cancel the license for 5BU (as aircraft are permitted to identify). In a separate action several months later, AGT requested cancellation of N5BU, effectively canceling Sorsby's amateur license. When N5BU became available for reassignment under the vanity system two years later, ARRL member David Willard of Ft Smith, Arkansas, filed for it and was granted the call sign last August. Sorsby blames a "security flaw" in the FCC's ULS software for allowing AGT's Peters to "inadvertently corrupt the database records" for his license. Similar problems have affected a small number of amateurs with N-prefix call signs in the past. The Iowa amateur is philosophical about the four months he spent getting N5BU returned. "It has been a very time-consuming and frustrating ordeal," he told ARRL. "My consolation for the ordeal is that now I'll have a tall tale to spin for years to come." To reduce the likelihood of similar problems, ARRL strongly encourages Amateur Service licensees to obtain an FRN via the FCC's Universal Licensing System Web page <http://wireless.fcc.gov/uls> (click on "REGISTER CORES/CALL SIGN") and then to associate their Amateur Radio call sign with their FRN. "This prevents other entities from inadvertently making changes to your Amateur Radio license and call sign," said ARRL Regulatory Information Branch Specialist John Hennessee, N1KB. ==>IARU MARKS WORLD AMATEUR RADIO DAY APRIL 18 Sunday, April 18, marks World Amateur Radio Day--the 79th anniversary of the founding of the International Amateur Radio Union (IARU). As it begins its 80th year, the IARU is recognizing radio amateurs worldwide as "Pioneers in Bridging Barriers to World Understanding." The IARU's inaugural meeting took place in Paris on April 18, 1925, when exploration of "the short waves" was just beginning. "Radio amateurs were well ahead of their commercial counterparts in exploiting the long-distance capabilities of this unique part of the radio spectrum," the IARU notes. "The technical contributions of the amateurs were very important to subsequent telecommunication development, and remain so today." Equally significant are the personal relationships that have developed between amateurs, often across geographical, political, cultural, and other barriers. Today there are nearly three million amateur licensees in nearly every country of the world. Radio amateurs continue to build and maintain personal ties in a world that is in ever greater need of mutual understanding. A worldwide federation of national Amateur Radio organizations representing radio amateurs in 159 countries, the IARU is a Sector Member of the International Telecommunication Union <http://www.itu.int/home/index.html> and is the recognized representative of the Amateur and Amateur-Satellite Services at the ITU.

Average daily sunspot numbers for the week were down over 44 points to 33.4, and solar flux was down 15 points to 91.5. Spring generally is a good time of year for HF propagation, although activity this low will reduce openings on 10, 12 and 15 meters. Currently Sunspot 591 is rotating away from Earth, while sunspots 592 and 594 are coming into full view. These are not large spots, however. The solar flux is expected to rise above 100 this weekend, April 17-18, and reach a peak around 120 on or near April 24. There is a small possibility of a coronal mass ejection April 16 from Sunspot 591. Sunspot numbers for April 8 through 14 were 33, 18, 20, 16, 37, 41 and 69, with a mean of 33.4. The 10.7 cm flux was 93.5, 90, 87.7, 89.6, 91.3, 93.1 and 95.2, with a mean of 91.5. Estimated planetary A indices were 16, 16, 10, 8, 11, 6 and 5, with a mean of 10.3. __________________________________ ==>IN BRIEF: * This weekend on the radio: The Holyland DX Contest, the TARA Skirmish Digital Prefix Contest, the ES Open HF Championship, the YU DX Contest, the GACW "Mr Samuel Morse Party" CW DX Contest, the EU Spring Sprint (CW), the Michigan and Ontario QSO parties and the EA QRP CW Contest are the weekend of April 17-18.

Conference discount rates are available (click on "Reservations"). * Hawaii amateur antenna bills headed for conference: Two amateur antenna bills in play in the Hawaii State Legislature, HB 2773 and HB 2774, passed a third reading in the Senate April 13. The legislation would allow Amateur Radio antennas in restricted condominium regimes and in subdivisions subject to homeowners' association covenants, conditions and restrictions (CC&Rs) in Hawaii. ARRL Pacific Section Manager Kevin Bogan, AH6QO, reports the measures now will go to a House-Senate conference to iron out differences. "Now the real work begins in hammering out bills that give us reasonable accommodation," Bogan said this week. "If we cannot come to an agreeable understanding with the associations on this, the bills may still die." He says the Amateur Radio community has been working on substitute language for the two pieces of legislation that would satisfy the homeowners' associations while still accommodating amateur antennas. =========================================================== The ARRL Letter is published Fridays, 50 times each year, by the American Radio Relay League--The National Association For Amateur Radio--225 Main St, Newington, CT 06111; tel 860-594-0200; fax 860-594-0259; <http://www.arrl.org/>.
