A signal transmitted on 184 kHz from ZL6QH--the Wellington, New Zealand, Amateur Radio Club's Quartz Hill station--has spanned the Pacific. The transmission, part of a series of announced transpacific tests, was received on June 30 by Steve McDonald, VE7SL, of British Columbia, Canada. "A claim is made for the confirmed reception of ZL6QH by VE7SL, on 184.4 kHz, over a path of 11,709 km," said Bob Vernall ZL2CA, who organized the transpacific tests. "This is a one-way confirmation, as VE7SL does not have transmitting capability." Vernall said that on June 30, seven New Zealand stations--including ZL6QH--and one Australian transmitted test signals in the 160-190 kHz band for the transpacific tests. Amateurs in New Zealand have access to that band. Reception of weak LF signals typically is done using spectrographic software. McDonald used Argo software to capture the ZL6QH signal and very likely that of ZL4OL, although no claim was being made for the latter. The reception occurred right around the time of sunrise in British Columbia. ZL6QH was transmitting dual-frequency CW with two-minute elements, one frequency representing dits, the other dahs. The ZL6QH station was running approximately 100 W into a longwire antenna. Amateurs spanned the Atlantic in both directions earlier this year on 136 kHz. Efforts to make it across the Pacific on LF have been under way during the winter season in the Southern Hemisphere. The ARRL has petitioned the FCC to authorize Amateur Radio allocations at 136 kHz and in the 160-190 kHz band. The petition is pending. ==>ASTRONAUT GREETS PARENTS DURING NEW MEXICO ARISS QSO Astronaut Susan Helms, KC7NHZ, briefly greeted her parents via Amateur Radio June 27 before answering questions posed by youngsters visiting the New Mexico Museum of Natural History and Science in Albuquerque. The contact was arranged at Helms' request by the Amateur Radio on the International Space Station--or ARISS--program. "Hi, Mom, hi Dad!" Helms said to her parents, before turning to the youngsters' questions. Patrick and Doris Helms live in Albuquerque and serve as volunteers at the museum. It took several calls to raise Helms at the NA1SS mike aboard the ISS. Once contact was established, however, she reported being able to hear the Earth station's calls for two or three minutes before NA1SS was heard on the ground. Jerry Schmitt, KK5YY, who set up the Earth station, said part of the museum building was in the signal path. Joe Huffman, KG5GM--also a museum volunteer--was at the mike of the Earth station to establish the initial contact. Seven third, fourth and fifth-graders--all enrolled in the museum's Space and Astronomy Day Camp--stood by with their questions in hand. Given the tardy start and a mid-QSO change in frequency, not all youngsters had a chance to ask their questions, however. Elementary pupils from a nearby school also were on hand as visitors. Helms told the youngsters that music sounds the same in space and that the view from the ISS is "a spectacular sight," with the blue Earth and white cloud cover surrounded by a layer of air--although space, by contrast, is "absolutely dark, absolutely black," she said. The astronauts are able to spot large physical features on Earth, she said. "You can see the Grand Canyon and the Great Wall of China with no problem." Schmitt, an engineer with Los Alamos National Labs, answered youngsters' questions following the contact. Jim Baremore, K5QQ, Brian Mileshosky, N5ZGT, and Paul Henckel, KA5H, assisted in the contact. Helms also took the mike as RS0ISS on July 4 to speak with students at the St Petersburg, Russia, Junior Technical Centre, RZ1AWO. This marked the first European school contact arranged under ARISS. "It was really successful," said earthbound chief operator Boris Kirshenblat, UA1AAF. Two young hams were among the students asking questions.

Recent efforts to raise the satellite's orbit at perigee--its point closest to Earth--were somewhat more successful than originally anticipated. Ground controllers had planned to lift the perigee from 280 km to around 500 km. Successive firings of cold arcjet ammonia fuel resulted in an orbit that's 851 km at perigee, however. "Indeed, the good news is that AO-40 is now in a safe and stable orbit!" said AMSAT-DL President Peter Guelzow, DB2OS, on behalf of the AO-40 team. "The bad news: All 53 kg of ammonia probably has been used up." This means further orbital adjustments--at least using the arcjet--are unlikely. Guelzow said ammonia stopped flowing after orbit 302, "and the pressure indicators in the telemetry show no more pressure in the motor and in the ammonia tanks, while the perigee clearly is higher than anticipated." AO-40's height at apogee--58,971 km--was unchanged by the orbital adjustment. Guelzow said stored telemetry was being downloaded and analyzed. Shut down prior to the start of the orbital adjustment, AO-40's transponders remain off the air. They will stay off as ground controllers adjust the satellite's attitude using on-board magnetorquing. AMSAT-NA President Robin Haighton, VE3FRH, has said it's hoped that a slightly higher perigee for AO-40 will eliminate the effects of what he described as "a mysterious force" that alters the satellite's attitude when it comes through perigee. One theory, he said, is that atmospheric expansion caused by the current sunspot cycle peak was influencing the satellite's orbit in some way. The higher perigee should eliminate any atmospheric impact. For more information on AO-40, visit the AMSAT-DL Web site, <http://www.amsat-dl.org/> or the AMSAT-NA Web site, <http://www.amsat.org>.--thanks to AMSAT News Service ==>2001 ARRL/TAPR DIGITAL COMMUNICATIONS CONFERENCE SET The 20th ARRL and TAPR Digital Communications Conference will be held September 21-23 in Cincinnati.

"Chet" Atkins, W4CGP, of Nashville, Tennessee, died June 30. He was 77. Atkins reportedly died of cancer complications. Known as "Mister Guitar," Atkins--from East Tennessee--began his musical career in the 1930s playing fiddle. He earned his reputation as a guitarist, however, and went on to become the most-recorded solo instrumental musician in history. Formerly WA4CZD, Atkins, a General licensee, in 1998 obtained the vanity call sign W4CGP--"certified guitar picker." He was an ARRL member. He won 14 Grammy awards during his career and was elevated to the Country Music Hall of Fame in 1973. He was presented with a Lifetime Achievement Award in 1993 by the National Academy of Recording Arts and Sciences in part to recognize his guitar-picking technique as well as his wide influence on music. He had more than 100 albums to his credit. In addition to his own success as a performer, Atkins helped launch the careers of other notable performers. He is given primary credit for developing the uptown "Nashville Sound" that helped country music to compete with pop music. In his later years of performing, he sometimes paired up with musicians from the pop and jazz worlds and was a frequent guest on the radio program "A Prairie Home Companion." A funeral service for Chet Atkins was held July 3 in Nashville's Ryman Auditorium, which formerly served as the home of The Grand Ole Opry where Atkins performed for many years. More information on Chet Atkins is on the Chet Atkins, Mister Guitar Web site <http://www.misterguitar.com/index.html>. ==>KC8BFD IS NEWSLINE'S 2001 YOUNG HAM OF THE YEAR Patrick Clark, KC8BFD, a 17-year-old ARRL member from Elkview, West Virginia, has been named the 2001 Amateur Radio Newsline Young Ham of the Year. Award Administrator Bill Pasternak, WA6ITF, says Clark is heavily involved in public service, emergency communications and youth recruitment. The Young Ham of the Year Award is jointly sponsored by Pasternak's Los Angeles-based Amateur Radio Newsline, Vertex Standard USA (Yaesu) and CQ magazine. The award is presented each year to a radio amateur 18 or younger who has provided outstanding service nationally or locally or has contributed to the betterment of the state of the art in communication through Amateur Radio. A licensee since age 10, Clark comes from an all-ham family. His father, Jeff, and mother, Tina, are K8JAC and N8TSY respectively; his sister, Erin, is KC8PZZ. Patrick Clark has been involved in emergency service work from the day his ham radio ticket arrived in the mail. He was among amateurs who responded in the wake of the West Virginia Field Day floods of 1998--when the annual emergency preparedness drill turned into the real thing as the skies unexpectedly opened up. In addition to his Amateur Radio Emergency Service activities, KC8BFD is also a certified severe weather spotter with SKYWARN. Clark has twice spoken at the Dayton Hamvention Youth Forum, and he promotes Amateur Radio to other youngsters through personal appearances. Among those supporting Patrick Clark's nomination was ARRL West Virginia Section Emergency Coordinator Morris "Mac" McMillian, W8XF. "I have always been able to rely on Patrick's ability to think on his feet in a drill or actual ARES activation," McMillian said, adding that he believes that the future of ham radio is in good hands with amateurs like Patrick Clark, KC8BFD. The 2001 Newsline Young Ham of the Year Award will be presented on Saturday, August 18, at the Huntsville Hamfest in Huntsville, Alabama. As Young Ham of the Year, Patrick Clark will receive--courtesy of Vertex Standard USA--an expense-paid trip to the 2001 Huntsville Hamfest, along with a gift of Yaesu ham radio equipment. CQ magazine will treat Clark to an expense-paid week at Spacecamp Huntsville and other gifts. Amateur Radio Newsline will present a commemorative plaque at the award ceremony.

The competition carries a $100,000 top prize. An independent panel judged Majumdar to be the overall winner as well as the winner for Asia. A member of the Calcutta VHF Amateur Radio Society, Majumdar won the top prize for designing a railway collision-avoidance system. His design incorporated a variety of Texas Instruments' power-management, interface, RF, logic and microcontroller products. The TI competition called on engineers to come up with real-world designs that utilized Texas Instruments devices. Texas Instruments said that Majumdar's Railway Collision Avoidance System 2001, or RACAS, "uses paired digital transponders for radio ranging and quasi-packet connectivity." Licensed since 1984, Majumdar is a founding member of the Calcutta VHF Amateur Radio Society and a life member. He's been an ARRL member since 1989. He's also a member of the Amateur Radio Society of India and of IEEE. Majumdar was active during the Orissa cyclone disaster operation in 1999 and took part in the Sagar mobile operation last year (see "Sagar 2000: Public Service in India," QST, May 2001, written by Kitchu's brother, Nilanjan "Horey" Majumdar, VU2HFR). In addition to public service and VHF and satellite activities, he's an avid DXer and HF CW, PSK31, and digital-mode operator.--thanks to CVARS ==>SOLAR UPDATE Solar sage Tad Cook, K7VVV, Seattle, Washington, reports: It has been a quiet week. There were no active or disturbed days, and solar activity declined. Average daily solar flux, compared the past week to the previous, declined over 51 points and average sunspot numbers were down more than 86 points. Activity will probably reach a short-term minimum on Friday and Saturday, when solar flux is around 115, then it is expected to rise back to 130 by July 10, and near 200 around July 13-20. No increased geomagnetic activity is forecast, but the emergence of new sunspots could change that. With summer here, MUF (Maximum Usable Frequency) is depressed. About the only openings on 10 meters are E-layer skip, which is somewhat sporadic and doesn't offer the longer distances of F layer communications. Twenty meters is open well into the night. Sunspot numbers for June 28 through July 4 were 143, 98, 115, 108, 130, 132 and 106, with a mean of 118.9. The 10.7-cm flux was 140.2, 139.9, 136.6, 135.4, 134.3, 131.9 and 127, with a mean of 135. Estimated planetary A indices were 5, 7, 10, 12, 8, 9 and 8 with a mean of 8.4. __________________________________ ==>IN BRIEF: * This weekend on the radio: The annual run of The Great Circus Train (W9D) with operation on 7.240 or 14.240 plus 146.55 MHz FM simplex (details at http://www.bsss.org) and the Venezuelan Independence Day Contest (SSB) are the weekend of July 7-8. JUST AHEAD: The IARU HF World Championship, the FISTS Summer Sprint, the CQ Worldwide VHF Contest and the QRP ARCI Summer Homebrew Sprint are the weekend of July 14-15. See the ARRL Contest Branch page, <http://www.arrl.org/contests/; and <http://www.hornucopia.com/contestcal/weeklycont.html> for more info. * ARRL Audio News shifts to single audio format: Starting with the July 6 edition, ARRL Audio News will be available only in MP3 format, which is compatible with currently available media software, including RealPlayer. ARRL Audio News will continue to be available for playback directly from the ARRL Web site <http://www.arrl.org/arrlletter/audio; or for downloading as an MP3 file. ARRL Audio News--a weekly Amateur Radio newscast--is available for personal or repeater playback without charge or special permission. ARRL Audio News will remain available as a dial-up telephone service at 860-594-0384. ARRL Senior News Editor Rick Lindquist, N1RL, produces the program. He said the change to MP3-only will mean consistently superior audio quality and eliminate the duplication of effort involved with producing the newscast in two audio formats. * Outgoing QSL Service tops one million cards for 2001: The ARRL's Outgoing QSL Service Manager Martin Cook, N1FOC, reports that as of June 29, 2001, the service had shipped 1,041,316 QSL cards. This includes cards going to US incoming bureaus and cards sorted and mailed by contractor. "This is an increase of 135,456--15%--more cards than we had mailed at this time last year," Cook said. The Outgoing QSL Service handled 1,868,895 cards in 2000. For more information, visit the ARRL Outgoing QSL Service Web site, <http://www.arrl.org/qsl/qslout.html>. * New York cell phone law does not apply to Amateur Radio: The widely reported New York bill banning the use of hand-held cell phone while driving should have no affect on Amateur Radio mobile operation, according to ARRL General Counsel Chris Imlay, W3KD. "There is no ambiguity in the bill," he said. The bill, A.9280, was signed into law recently by Gov George Pataki, a former amateur. It requires cell phone users to use hands-free devices when calling. The measure specifies "mobile telephone" use, and defines a "mobile telephone" as a device used by subscribers to a wireless telephone service. That, in turn, is defined to specify a commercial two-way wireless telecommunications service that accesses the public switched telephone network. The bill also specifies "using" as holding the mobile telephone "to, or in the immediate proximity of, the user's ear." The new law will be phased in starting November 1. It calls for fines of up to $100. The measure also calls upon the New York Commissioner of Motor Vehicles to study the effects of the use of mobile telephones "and similar equipment" in conjunction with the operation of a motor vehicle and report back to the legislature in four years. The full text of the measure is available on the New York legislature's Web site <http://assembly.state.ny.us/leg/?bn=A09280&sh=t> . A similar measure requiring hands-free cellular telephones recently passed the Rhode Island legislature. * Museum ship special event set for July 21-22: Amateur Radio stations aboard or associated with some 60 historic vessels will be on the air July 21-22 for the annual museum ship special event. The yearly outing is sponsored by the USS Salem Radio Club, K1USN, in Quincy, Massachusetts. Warships, submarines and various motorized vessels from WW II and earlier from the US and elsewhere will be on the air. All have a history and a story to tell. A certificate is available. Visit the USS Salem Web page <http://www.qsl.net/k1usn/event.html> for a list of participating ships, operating frequencies and certificate information. * New York amateur antenna bill a step closer to passage: ARRL Hudson Division Director Frank Fallon, N2FF, says that New York's Amateur Radio antenna bill, Assembly Bill 1565, has been reported out of the Ways and Means Committee. Both A. 1565 and the companion bill, S. 2893, are in the Rules Committee, where they can immediately be brought to the floor before the 2001 session ends. Fallon says the legislative session resumes July 10. "The good news is that it's not over yet, but the bad news is that we have to continue to make the telephone calls, write the letters and send the e-mails," Fallon said. "We need to continue pushing for action on the bills." Fallon urged New York hams to continue sending the same message to Albany, "Please enact the Amateur Radio legislation." He said Senate Majority Leader Joe Bruno <email@example.com>, House Speaker Sheldon Silver <firstname.lastname@example.org> and Gov George Pataki <email@example.com>--a former ham (K2ZCZ) and a current ARRL member--each have the power to bring these bills to the floor for a vote. "We need to ask them to do so, now." Additional information on how to contact key lawmakers is available on the Hudson Division Web site, <http://www.arrlhudson.org>. "You may want to send QSL cards this time around," Fallon said. "The governor knows what they are." * Ten-Tec solicits comments on pending transceiver: Ten-Tec is looking for comments and suggestions from the amateur community on its proposed Model 516 "IF-DSP" low-power (variable from 1-5 W) HF transceiver--a general coverage, software-defined radio. The rig is expected to be on the street by next January at a price under $600. It will offer CW, SSB and FM and AM and 38 DSP filters from 200 Hz to 8 kHz. Because of its software-defined design, Ten-Tec will be able to incorporate changes much later in its production schedule than typically is possible with discrete-component design. Ten-Tec says almost all functions and features are stored in flash ROM. To add new features, users will download the latest software version from the Ten-Tec Web site. Ten-Tec invites suggestions for features to be incorporated in the new radio via e-mail, firstname.lastname@example.org. Details on the transceiver are available on the Ten-Tec Web site, <http://www.tentec.com/TT516.htm>. * July is IOTA Month: DXers who participate in the IOTA (Islands On The Air) program, sponsored by the Radio Society of Great Britain (RSGB), know that July is IOTA Month. This is quite possibly the best month to work a new one, because so many people in the Northern Hemisphere go on IOTA DXpeditions at this time of year, especially during the RSGB IOTA Contest the last full weekend of the month. If you are just starting out in this DX award program you can easily work your first 100 IOTA counters and some of the more serious operators can work well over 200. This year's contest will be held on the weekend of July 28-29. For more information on IOTA, visit the RSGB's Islands on the Air Web site, <http://www.rsgbiota.org/>. * French RAC Web site to close: Radio Amateurs of Canada has announced that it's closing "with regret" its French-language Web site. RAC said it attempted in vain for more than a year to find a volunteer with the time and skills to manage the French language pages on the RAC Web site. "Much of the information is no longer current, and we have therefore reluctantly decided that as of June 30 we will close down the French pages and replace them with links to other francophone sites," an RAC announcement said. "We apologize to those of our members who make use of our services in the French language."
