The Hurricane Watch Net (HWN) on 14.325 MHz this week has been working
hand-in-hand with WX4NHC at the National Hurricane Center (NHC) to relay
weather data and damage reports as a downgraded Hurricane Frances
continues on what appears to be an inevitable collision with Florida's
Atlantic Coast. As of September 3 at 1800 UTC, the National Hurricane
Center said Frances was "relentlessly lashing central and western Bahamas"
while slowly heading for Florida.

"We continue to have torrential rains," Marti Brown, KF4TRG/C6A, on Abaco
reported to the HWN net control station September 3. "It's essentially a
whiteout condition." Her report, typical of those being gathered, may
portend what Southern Florida can expect. Another Amateur Radio report
from the Bahamas indicated that seas were breaching the dunes of the
beach, and residents were evacuating.

All such reports, typically including real-time measured weather data, are
passed along to WX4NHC at the National Hurricane Center for forecasters to
review. HWN operators have been handling and relaying all reports with
businesslike efficiency, despite occasional QRM--some of it possibly

HWN Manager Mike Pilgrim, K5MP, in Boca Raton, Florida, briefly checked
into the net using an indoor antenna "in case we need it," he told net
control. The latest National Hurricane Center forecast is available via
the HWN Web site <>, which
includes graphics.

During hurricanes and severe weather emergencies, trained HWN members work
in cooperation with WX4NHC to relay observed or measured weather data and
damage reports to forecasters via Amateur Radio. The ground-level weather
data assist NHC forecasters in predicting a storm's path and behavior.

Frances was downgraded September 3 to a Category 3 hurricane, with winds
of 115 MPH with higher gusts. Its forward motion was expected to continue
to slow, however, perhaps buying some time for Floridians preparing for or
escaping the storm's anticipated wrath.

As the state continued to recover from Hurricane Charley in mid-August,
Amateur Radio Emergency Service (ARES) teams throughout Florida this week
got ready for another punishing storm. Some communities hard-hit by
Charley are in the potential path of Hurricane Frances.

Special sessions of the Southern Florida ARES Net (SFAN) to coordinate
response activities (Florida Midday Traffic Net and Tropical Phone Traffic
Net, both on 7242 kHZ) were called up this week. Southern Florida ARES
Section Emergency Coordinator Jim Goldsberry, KD4GR, says the Broward
County Emergency Preparedness Net activated September 2 from the Broward
County emergency operations center (EOC).

Palm Beach County also was recruiting ARES volunteers for shelter and EOC
communicator duty. Palm Beach County RACES Officer Mark Filla, KS4VT,
reported coastline and mobile home evacuations were under way.

"This is not a drill," emphasized Polk County Assistant Emergency
Coordinator Wayne Miles, KG4TCJ, in a message to the Florida ARES
reflector. Among the areas assaulted by Hurricane Charley, Polk County
ARES has begun conducting informational nets (146.985 MHz, 127.3 Hz tone)
at the top of every hour.

Earlier this week, Indian River County Emergency Management's Nathan
McCollum put that county's Auxiliary Communication Services (ACS)--a
Citizen Corps group--on a "Level 1" alert. The ACS includes Amateur Radio
and REACT communication resources.

SATERN, the Salvation Army Team Emergency Radio Network, planned to
activate September 4 at 1400 UTC on 14.265 MHz. SATERN will handle
emergency and health-and-welfare traffic for those attempting to get news
of friend and relatives in the affected areas. SATERN also accepts
specific H&W inquiries via its Web page <>.

A fairly new all-CW entity, the National Radio Emergency Net (NREN),
activated September 3 in response to Hurricane Frances to monitor 14,050
kHz and 7050 kHz for health-and-welfare, emergency traffic and hurricane
information throughout the weekend. NREN is geared to low-power, portable
and mobile stations.

ARRL West Central Florida Section Manager Dave Armbrust, AE4MR, said
Hillsborough County and Sarasota County ARES were preparing for ARES
Mutual Assistance Team (ARESMAT) deployments. "If your county is not
directly hit, please be ready to lend a hand elsewhere if requested," he

In a message to the Tampa Amateur Radio Club Hillsborough County of
Emergency Management Director Larry Gispert, KR4X, said that many
emergency workers were "very impressed" by what Amateur Radio volunteers
were able to accomplish during Hurricane Charley.

"In this day and age of ubiquitous Internet access and prolific cell phone
usage, it is still amazing that when the chips are down the only reliable
form of communication is a bunch of hams with their radios," Gispert said.


While the ARRL has accused the FCC of sweeping under the rug several
Amateur Radio complaints of interference from unlicensed broadband over
power line (BPL) devices, the Commission apparently is not ignoring other
Part 15-related interference complaints from hams. With the assistance of
the ARRL Laboratory, the FCC continues to dog complaints--some now
longstanding--of power-line noise interference to amateur communication.
Other cases of Part 15 device interference to radio amateurs have been a
bit more exotic. For example, two recent citations issued by the Portland,
Oregon, FCC field office involved interference from wireless microphones
operating in the 70-cm band.

"The agent measured the field strength at 1500 uV/meter at a distance of 3
meters from the referenced wireless microphones and determined that the
microphones were in noncompliance with §15.209 of the Commission's rules,
which apply to intentional radiators," the FCC said.

Daniel Bathurst, WA7ABU, of Salem, Oregon, filed the complaint. In
citations to FLECO Corp of Chino, California, and The Club Works Sound and
Lighting of Salem, the Commission alleged that the devices, which operate
on 432.55 and 439.55 MHz, also were not certificated for sale in the US.
The FCC citation indicated that FLECO had sold the microphones to The Club

As reported, the FCC earlier this year fined Best Wok, a Westville, New
Jersey, restaurant $10,000 for operating transmitting equipment on the 2
meter satellite subband without a license. The eatery allegedly was using
a so-called "long-range cordless telephone" to communicate with its
delivery vehicle.

Other recent cases have stemmed from radio amateurs' complaints about
their neighbors' Part 15 devices. In a Texas case that FCC Special Counsel
for Enforcement Riley Hollingsworth described as "an unfortunate
neighborhood situation," the neighbor allegedly not only failed to respond
to FCC letters but tossed out the toroid core devices the amateur, William
Cooper, W5ZAF, had provided free and which, the FCC said, had resolved the

Hollingsworth told the neighbor that under Part 15, operation of a
consumer product "such as a battery charger" must not result in harmful
interference to a licensed radio service. He emphasized that it's the
neighbor's responsibility to correct the interference--whether or not the
neighbor accepts Cooper's help.

In a similar case in Colorado, Hollingsworth on August 10 wrote another
amateur's neighbor about interference from an electric fence charger to
the Amateur Radio and broadcast television reception of P. E. Muetz,

"Operation of a consumer device such as your fence charger under Part 15
of the Commission's rules must not result in harmful interference to a
licensed radio service, and Part 15 of our rules clearly explains that,"
said Hollingsworth, who'd also spoken with the neighbor by telephone last

In a seeming turnabout-is-fair-play situation, the FCC contacted a
Mattawan, Michigan, resident to follow up on complaints that the
individual's TV set was causing harmful interference to the Amateur Radio
operations of Robert Lawson, KG8QD. Sharon Bowers, deputy chief of the
FCC's Consumer Inquiries and Complaint Division, noted that Part 15
obliges the TV set's owner to resolve the interference promptly. Under
Part 15, a TV set or a computer monitor is considered an "unintentional

In July, the FCC contacted Illinois Power Company to report receiving
complaints that the utility's equipment may be causing harmful
interference to the amateur operations of Earl Shaffer, WB9UWA, of Normal.

"The complainant has attempted unsuccessfully to work through your usual
complaint resolution process, and, as a result, the matter has been
referred to our office," Bowers said in a form letter to the utility's
CEO. In both cases she handled, Bowers provided the address, telephone
number and e-mail address of the ARRL's Radio Frequency Interference Desk
as a source of "help and guidance about radio interference that involves
Amateur Radio operators." More than five dozen power line interference
cases have been referred to the League this year.


NASA International Space Station Science Officer Mike Fincke, KE5AIT, told
students at Pennsylvania's Upper St Clair High School August 27 that life
in space is both fun and, at times, challenging. The Amateur Radio on the
International Space Station (ARISS) school group contact between NA1SS in
space and WB4GCS in Western Pennsylvania represented a homecoming of sorts
for Fincke, who was born in Pittsburgh and whose parents live in Emsworth,
where he grew up. Fincke said problems with an onboard gyroscope system
that occurred just as the Expedition 9 crew arrived aboard the ISS
presented the most unexpected challenge to date of his six-month tour of

"Our biggest challenge was to get some spacesuits and get outside and fix
it, and it turned out that the American spacesuits were broken, and we had
to go to our backup plan with the Russian spacesuits," Fincke recounted.
"That took a lot of work. That was a big challenge, but we were successful
on the Fourth of July weekend, and we fixed that gyroscope's power
source." The challenge aside, Fincke said, the experience was "really

Although he's missed his wife and children while in space since April,
Fincke says he's enjoying his time aboard the ISS.

"The most fun I've ever had in space has been every day since I got here,"
he said in reply to a youngster's question. "I've been waiting my whole
life, and every day aboard the space station has been a great day. There's
always something new, something new to learn, something new to see."

Fincke said he'd like to see the human space flight program focus on once
again landing on the moon, journeying to Mars and eventually to the stars.
"We need to explore who we are and our potential as human beings."

Fincke also philosophized in response to a question about the perspective
he's gained from living in space. "Every piece of history, everything
we've ever talked about, every poem that was ever created, every heart
that was broken, every joy that was felt is just on that ball of rock
that's below us right now, and that really puts things into perspective."

The Expedition 9 crew is scheduled to return to Earth in about six weeks.

Mentoring the ARISS contact was Howard Ziserman, WA3GOV. Jim Sanford,
WB4GCS, served as the control operator. Setting up the Earth station for
the contact were the Wireless Association of South Hills (WASH) and
Washington Amateur Communications (WACOM), with assistance from local
AMSAT members.

ARISS is an educational outreach with US participation by ARRL, AMSAT and


The ARRL Education and Technology Program (ETP--also known as "The Big
Project") will offer a new activity board to schools this fall. ETP
Coordinator Mark Spencer, WA8SME, says the "L/C/Resonance" or L/C/R
activity board will allow students to explore many facets of alternating
current and RF theory. The board will help students to unravel the
mysteries of capacitive and inductive reactance, verify reactance formulas
using actual data taken from the activity board, measure the resonant
frequency of either series or parallel L/C circuits and then put it all
together to explore the relationship between capacitive and inductive
reactance and resonance. And there's more, Spencer points out.

"Because the board uses a microcontroller and a digital-to-analog
converter (DAC) to generate the ac waveform used to explore L/C circuits,
there is an additional learning opportunity: digital signal processing
(DSP) fundamentals," he notes. "This facet of the board leads to
exploration of root mean square (rms) voltage and current and the
mathematical derivation of rms."

Given the level of mathematics involved, Spencer says the activity board
is intended primarily for high school physics or second-year algebra
students. But, he adds, anyone studying for the General or Amateur Extra
license examination could benefit from the learning opportunities the
L/C/R activity board affords.

"In other words," Spencer says, "there is a whole lot of activity packed
into this little board."

Students use mathematical, graphing, graphing calculator, spreadsheet and
critical-thinking skills to make sense of the data collected during the
various board activities. For example, students use graphing calculator
curve-fitting techniques to verify the reactance formulas. Drawing on the
premise that one picture is worth a thousand words, Spencer says,
spreadsheet software helps students visualize the raw voltage and current
data measurements.

During the DSP activities, students use the OptaScope digital oscilloscope
to see the stair-step waveform generated by the computer and the DAC on
one channel, and the smoothed waveform exiting a simple filter on the
other. "Visualizing a waveform in discrete slices helps students
understand what happens during DSP," Spencer explains.

The L/C/R activity board kit includes the circuit board, the parts to
populate it, plus documentation to support the board's construction and
use. As with previous activity boards, this one is designed to be
constructed by students under adult supervision.

Activity board kits are available to interested and qualified schools
through generous donations to the Education and Technology Program Fund.
To qualify for one of these kits, interested schools need to write Spencer
on school letterhead and verify that (1) the lead teacher has reviewed the
curriculum that supports the L/C/R activity board, (2) the curriculum and
the board fit into the school's curriculum and the school intends to use
the board as an instructional activity, and (3) the school has the
capability to build the activity board (preferably, students will do the
actual construction).

For schools wishing to roll their own, all documentation, diagrams, a
parts list, and software in hard copy are available simply for the asking.
Send requests to Mark Spencer, WA8SME, ARRL, 225 Main St, Newington, CT

Another new activity board kit, to be available in January 2005, is a
simple and inexpensive direct-conversion receiver kit, produced by the
American QRP Club.

Technology Program, contact Mark Spencer, WA8SME, 860-594-0396; To learn more about how to support the ARRL Education

The Amateur Radio on the International Space Station (ARISS) program this
week put one of the two ham stations aboard the ISS to use as a U/V (Mode
B) FM repeater (437.80 MHz up and 145.80 MHz down). The new Phase 2 ISS
ham gear--primarily used for packet operation and tests and briefly by
Expedition 9 Commander Gennady Padalka, RN3DT, during Field Day 2004--was
pressed into service for several days as a low-Earth-orbiting FM
"EasySat." The crossband repeater experiment, announced August 28, was
shut down with the other ARISS gear September 2 in preparation for a
September 3 space walk. The Amateur Radio equipment aboard the ISS will be
powered back up no sooner than 1700 UTC on September 4, said ISS Ham Radio
Project Engineer Ken Ransom, N5VHC.

"Mike Fincke [KE5AIT] reported hearing stations actively using the
repeater over North America, the southern portion of South America, South
Africa, Europe, Australia and Japan," Ransom said. He got lucky on the ISS
repeater September 2, snagging a QSO with V31KD in Belize City, Belize

The Phase 2 gear was scheduled to return to RS0ISS packet operation
following the space walk, but the repeater experiment could be back for a
"repeat" performance. ARISS International Team Chairman Frank Bauer,
KA3HDO, said the crossband repeater test provided an opportunity to
further experiment with the ISS Amateur Radio system.

Last December, ISS Expedition 8 Commander Mike Foale, KB5UAC, set up a new
Kenwood TM-D700 Phase 2 dualband transceiver in the ISS Zvezda Service
Module--the crew's living quarters. With the help of the ARISS Japan team,
Kenwood donated the TM-D700 transceivers to ARISS and made specific
hardware and firmware modifications--including limiting its power output
to a maximum of 25 W--to prepare it for flight. Plans call for using the
Phase 2 station at 10 W output during ARISS school group QSOs, starting
with the arrival of the Expedition 10 crew this fall.


The ARRL DX Century Club Program (DXCC) has announced that, effective
immediately, there no longer will be a submission deadline for the DXCC
Annual List.

"We have been working toward this end for several years," says ARRL DXCC
Manager Bill Moore, NC1L. In the past, he explains, September 30 has been
the traditional cutoff date to compile entity totals for the DXCC Annual
List, published in the DXCC Yearbook.

Moore says that in the past, DXCC participants have tended to collect
their cards and submit them once a year to ensure the highest possible
total for the listing. A major downside of the deadline system is that
DXCC typically has received more than 25 percent of annual credit
submissions during September. That, in turn, created a huge increase in
workload and lengthened processing time.

Under the deadline-free system, complete lists on the ARRL Web site will
replace the lists of DXCC standings that customarily have appeared in the
DXCC Yearbook. The new Web-based lists should be on-line early in the
first quarter of 2005--about the time the DXCC Yearbook typically
publishes. After an initial posting, DXCC will regularly update the Web
lists. These listings also will include the standings of all DXCC members,
not just those who made a submission in the previous year, as had been the

ARRL will publish a scaled-down version of the DXCC Yearbook that will
contain highlights of the standings, along with other features. For more

Propagation maven Tad "Sunshine Superman" Cook, K7RA, Seattle, Washington,
reports: Sunspot numbers and solar flux values declined this week compared
to last. The average daily sunspot number dropped by nearly 50 to 27.7,
and the average daily solar flux was down more than 23 points. Geomagnetic
activity increased on August 30 and 31, sparked by a moderate solar wind

The predicted solar flux values for Friday, September 3, through Monday,
September 6, are 100, 105, 110 and 115. Solar flux is expected to peak
around 130 on September 9.

The planetary A index for September 3-6 is predicted at 15, 10, 10, and
10. The planetary A index may rise higher around September 5 due to a
solar wind stream from a coronal hole. This could produce unsettled to
active geomagnetic conditions.

Sunspot numbers for August 26 through September 1 were 44, 33, 28, 36, 30,
11 and 12, with a mean of 27.7. The 10.7 cm flux was 97.5, 90.5, 87.2,
86.1, 89.9, 88.1 and 89.9, with a mean of 89.9. Estimated planetary A
indices were 7, 8, 12, 8, 34, 28 and 9, with a mean of 15.1. Estimated
mid-latitude A indices were 4, 4, 6, 5, 27, 14 and 5, with a mean of 9.3.

* "The Beeb" to air program on Amateur Radio and 9/11: BBC Radio 4 this
weekend will air a documentary on Amateur Radio's involvement in the
September 11, 2001, terrorist attacks. The half-hour program, "Unsung
Heroes," will be broadcast Saturday, September 4, at 1030 UTC. It will
remain available on the BBC's archives for one month after that. "Through
moving interviews, sensitive use of ham radio transmissions and some
harrowing accounts, 'Unsung Heroes' reveals the little-known story of the
9/11 ham radio operators who provided vital communication networks for the
rescue agencies," the BBC program listing says. "Hams, often mocked for
their obsessive hobby, believe that September 11th became Amateur Radio's
finest hour. Stephen Evans, the BBC's North American Business
Correspondent, witnessed the attacks that day and meets with ham operators
who witnessed the terrorist attacks or lost friends and relatives on
September 11th and still helped to support the search-and-rescue
operation." Mark Phillips, KC2ENI/G7LTT, says the program, produced by
Kate Bissell, features N2NOV, KF2EO, KE2UN, AB2IZ, "and a whole host of
others," including himself. It was recorded during the last week of June.
The program also be available in MP3 format on Phillips' Web site
<> starting September 4.

* Opportunities Fair showcases ham radio for retirees: ARRL Honorary Vice
President Hugh Turnbull, W3ABC, Bob Barnes, KR3X, and his wife Pat,
KB3BTB, hosted an Amateur Radio demonstration Friday, August 20, at the
Riderwood Village retirement complex in Silver Spring, Maryland, where all
reside. The display was part of the complex's annual Opportunities Fair.
"Along with about 35 other special-interest groups, we welcomed the
opportunity to acquaint the other residents with another way to spend
their time," Turnbull said. "Our table featured some ham radio
memorabilia, QSL cards, an operating 2 meter station and a code practice
machine to provide some Morse Code 'background music.'" Turnbull said the
timing of their demonstration turned out to be "opportune" as well--coming
just as local media were praising the Amateur Radio community for
assisting in providing communication when Prince George's Hospital Center
in Cheverly lost its main telephone system for about 10 hours. Turnbull
said that while their demonstration table might not result in any new
licensees, it did contribute to a better-informed public. "We continued
the education process from what people read in the morning paper about the
telephone outage," he said.
