MENA, Ark. (AP) — A tornado struck a small Arkansas town Thursday night, killing three people, injuring at least 24 and seriously damaging about 100 homes.

Mena, near the Oklahoma state line, suffered a direct hit that destroyed at least 10 businesses, including city hall and two churches, Polk County emergency coordinator James Reeves said.

"One manufacturing plant is gone," he said. "It took a direct hit. It's no longer there."

The National Weather Service said a woman was injured at Shreveport, La., when a tree fell onto her car during a tornado. Twisters also damaged homes east of Vinita and near Muse in Oklahoma and at Crossett in far southern Arkansas, near the Louisiana line.

At Mena, one of the victims killed in the storm was found in a collapsed house, one in a Masonic lodge, and another was found in her front yard, he said. The identities of the two women and a man have not been released.

The 24 injured people were being treated at Mena Medical Center. The devastated downtown area was being protected by National Guard troops dispatched by Gov. Mike Beebe.

A curfew was in effect as emergency crews dealt with ruptured gas lines, downed power lines, fallen trees and heavily damaged buildings.

Reeves said he had never seen a storm like this hit the tornado-prone region.

"Not in my life time," he said. "The last tornado we had to hit the city of Mena was in November 1993. This time we had significant structures (hit)."

Officials described a chaotic scene Thursday night as the tornado struck, part of a line of severe storms that strafed parts of Texas, Oklahoma, Arkansas and Missouri.

A state trooper in Mena called for assistance after his patrol car got stuck in the storm, pelted with debris and covered with power lines, state police spokesman Bill Sadler said.

"I'm in the middle of a tornado," Sadler said the trooper reported.

The National Weather Service reported that 3-inch diameter hail — forecasters described it as apple-sized — fell south of Mena just before the tornado hit downtown. Tornado damage was also reported at Ink, 5 miles east of Mena.

A twister damaged chicken houses in Howard County and another storm damaged an oil rig in Miller County, near the Louisiana and Texas state lines. At DeQueen, a number of mobile homes were damaged, according to Renee Preslar, a spokeswoman for the state Department of Emergency Management.

Violent thunderstorms moved quickly across southern Missouri, carrying large hail, winds up to 60 and 70 mph and reports of funnel clouds and tornadoes. There were no immediate reports of heavy damage. Scattered power outages were reported in several counties.

As the storms moved east, hail and high winds were reported in Alabama, Kentucky, Mississippi and Tennessee. Power was out in many parts of the region.

EVE ! - Radio Amateurs bounce a signal off Venus

Radio Amateurs have achieved the very first reception of amateur signals bounced off the planet Venus, over 50 million km away - EVE (Earth-Venus-Earth)

Peter Guelzow DB2OS, President of AMSAT-DL has provided a description of this landmark achievement.

On March 25th, 2009 a team from the German space organisation AMSAT-DL reached another milestone on its way to an own interplanetary probe towards planet Mars.

The ground station at the Bochum observatory transmitted radio signals to Venus. After travelling almost 100 million kilometers and a round trip delay of about 5 minutes, they were clearly received as echoes from the surface of Venus.

Receiving these planetary echoes is a first for Germany and Europe. In addition, this is the farthest distance crossed by radio amateurs, over 100 times further than echoes from the moon (EME reflections).

For receiving the EVE signals, an FFT analysis with an integration time of 5 minutes was used. After integrating for 2 minutes only, the reflected signals were clearly visible in the display. Despite the bad weather, signals from Venus could be detected from 1038UT until the planet reached the local horizon.

The 2.4 GHz high power amplifier used for this achievement is described in the current AMSAT-DL journal.
This represented a crucial test for a final key component of the planned P5-A Mars mission. By receiving echoes from Venus, the ground and command station for the Mars probe has been cleared for operational use and the AMSAT team is now gearing up for building the P5-A space probe.

For financing the actual construction and launch, AMSAT-DL is currently
in negotiation with the DLR (Deutsches Zentrum für Luft- und Raumfahrt) amongst others, to obtain financial support for the remaining budget of 20 Mil Euros.

AMSAT-DL wants to show that low-cost interplanetary exploration is possible with its approach.

The EVE experiment was repeated on Thursday, March 26th for several hours with good echoes from Venus. Morse code was used to transmit the well known “HI“ signature known from the AMSAT OSCAR satellites.

FCC Clarifies What Constitutes an Amateur Radio Repeater

In December 2007, Gary Mitchell, WB6YRU, President of the NorthernCalifornia Packet Association (NCPA), filed a Petition with the FCC,asking for the Commission to clarify the definition of a repeater.According to Part 97, Section 3(a)(39), A repeater in the amateurservice is "[a]n amateur station that simultaneously retransmits thetransmission of another amateur station on a different channel orchannels."

Mitchell sought clarification on the word "simultaneously," askingif it referred to the signal information being retransmitted, or tothe fact that the receiver and transmitter must both be active atthe same time while acting on the same signal information. On March23, 2009, the Commission clarified that even if there is a slightdelay between what is received and what it transmits (as in the caseof D-STAR and other digital repeaters), it is consideredsimultaneous if the receiver and transmitter are both active at thesame time.

Mitchell pointed out in his petition that while the Commission'sRules specify on which bands amateur repeaters may operate, "someamateur repeaters are operating on bands other than set forth inSection 97.205(b) with systems that are essentially voice repeaterstations, but that digitize and retransmit the user's voice, on thetheory that because there is a small delay in retransmitting thesignal of another amateur station, the signal is not'simultaneously' retransmitted and, therefore, the system is not arepeater.

"In its reply, the Commission pointed out that prior to 1994, arepeater was defined as "[a]n amateur station that automaticallyretransmits the signals of other stations." This, the Commissiontold Mitchell, was revised to clarify "that certain accommodationsfor message forwarding systems do not apply to other operatingactivities such as repeaters and auxiliary stations." The Commissionproposed to define a repeater as "[a]n amateur station thatinstantaneously retransmits the transmission of another amateurstation on a different channel or channels," but ultimately replaced"instantaneously" with "simultaneously" because commenters notedthat there is always a small propagation delay through a repeater.As one commenter explained, "The word 'simultaneously' in this casemeans that the repeater is receiving and transmitting concurrently,whereas each signal might be slightly displaced in time betweenreceive and transmit."To be able to repeat another station's transmission, the Commissionsaid that a repeater "must be able to receive a transmission fromanother station and retransmit it. Because the word 'simultaneously'in the definition is used to modify 'retransmit,' we believe itrefers to a repeater station's transmitter being active whenretransmitting the signal received by the repeater station'sreceiver from another amateur station.

We conclude, therefore, that'simultaneously' as used in the definition of a repeater refers tothe receiver and transmitter both being active at the same time.

FCC Denies Petition to Increase Size of Amateur Radio Question Pools

In April 2008, Michael Mancuso, KI4NGN, of Raleigh, North Carolina,filed a petition with the FCC, seeking to increase the size of the question pools that make up the Amateur Radio licensing exams.Mancuso sought to increase the question pool from 10 times the number of questions on an exam to 50 times more questions.

On March19, 2009, the Commission notified Mancuso that it was denying his petition.In his 2008 petition, Mancuso claimed that the current question pool is too easy to memorize and "that there has been a significant increase in the number of Amateur Radio operators receiving their licenses over at least the last decade or more who do not appear to possess the knowledge indicated by the class of license that they have received.

Most discussion about this topic, both on the air an don Internet forums, generally refers to these widespread observations as the 'dumbing down' of Amateur Radio. It has been widely assumed that the cause of this observed situation is based upon the subject material addressed by the license examinations,that the material requirements specified for the examinations does[sic] not meet some minimum level of knowledge expected by some or many in the Amateur Radio community."

The FCC pointed out to Mancuso that each applicant for a new or upgraded Amateur Radio operator license "is required to pass a written examination in order to prove that he or she possesses the operational and technical qualifications required to perform properly the duties of an amateur service operator licensee, i.e.,that he or she is qualified to be an amateur service licensee."The Commission summed up Mancuso's petition, saying, "You argue that the current question pool size is no longer adequate, because online practice examinations enable examinees to memorize a question pool without fully comprehending the subject matter being tested.Consequently, you propose to increase the size of the question pools, in order to hinder memorization."

The Commission concluded that Mancuso did not present grounds for the Commission to amend its rules: "As noted above, the purpose of the examinations is not to demonstrate an applicant's comprehension of certain material, but rather to determine whether he or she can properly operate an amateur station. Moreover, your contention that there has been 'a significant increase in the number of Amateur Radio operators...who do not appear to possess the knowledge indicated by their class of license' is not supported by any data or facts."The FCC pointed out to Mancuso that the Commission's Rules only dictate the minimum number of questions for each question pool for the three Amateur Radio license classes.

This, the Commission told Mancuso, "does not prevent the National Conference of Volunteer Examiner Coordinators (NCVEC) from increasing the number of questions in a question pool should it decide that this is appropriate. We conclude, therefore, that the petition presents no evidence of an existing problem or other reason for a rule change."

Police Detonate Ham Radio Equipment Mistaken for Bomb

OMAHA (KPTM) - Police evacuated a midtown neighborhood briefly Thursday morning for what was originally thought to be a bomb, but in the end, it turned out to be ham radio equipment.

The house, located near 48th and Mayberry, caught fire last week. A cleaning company found the equipment and called police, thinking it was a pipe bomb.

Police were called, and officers detonated the equipment. The neighborhood was evacuated during the investigation.

ARRL Mobile Radio Statement

On January 30, at the instruction of the Board of Directors at its
January 2009 meeting, the ARRL Executive Committee adopted a policy
statement on mobile Amateur Radio operations. The statement
addresses the growing number of proposed state and local laws and
ordinances regulating the use of cellular telephone and text
messaging, inadvertently affecting Amateur Radio mobile
communications.

In its statement, the Executive Committee urges state and municipal
legislators to limit the scope of their proposals, limiting them to
devices such as full duplex wireless telephones and related
hand-held or portable equipment. Alternately, it suggests that
licensed Amateur Radio operation be listed specifically as an
exclusion to the proposed regulations.

"At the start of each new session, you see a flurry of this type of
proposal in state legislatures across the country," said ARRL
Regulatory Information Manager Dan Henderson, N1ND.

As of February 1, 2009, Henderson said that the ARRL is aware of
proposals in 11 states: Georgia, Hawaii Idaho, Illinois, Iowa,
Maine, Montana, Texas, Utah, Virginia and Wyoming, as well as
several local city or town proposals.

"These proposals are usually intended to regulate cellular telephone
and text messaging by drivers as a matter of safety but, when they
are written in very broad terms, can include Amateur Radio mobile
operations in the 'net' they cast," Henderson continued. "The
Executive Committee's policy statement gives a good, concise
background of the role the Amateur Service plays in public safety
and service communications. It also highlights the differences
between communications conducted by cellular telephone and those
using Amateur Radio. Finally, the statement offers some suggested
statutory language for state motor vehicle codes which would protect
Amateur Radio mobile operation."

The ARRL recognizes that driver inattention is a leading cause of
automobile accidents. The policy statement raises the fact that cell
phones utilize full duplex communications -- where the user is
talking and listening simultaneously. The Executive Committee
statement says "Two-way radio use is dissimilar from full-duplex
cellular telephone communications because the operator spends little
time actually transmitting; the time spent listening is more similar
to, and arguably less distracting than listening to a broadcast
radio, CD or MP3 player. There are no distinctions to be made
between or among Amateur Radio, public safety land mobile, private
land mobile or citizen's radio in terms of driver distraction. All
are distinguishable from mobile cellular telephone communications in
this respect."

The ARRL Policy Statement also recognizes the responsibility of the
amateur community to conduct its activities in a manner that does
not create unsafe operation of their motor vehicle. "Safety has to
be a top concern at all times," Henderson concluded.

Skywarn Recognition Day - December 6th

Newington, CT November 12, 2008 -- Skywarn Recognition Day. When you are unsure about the weather you look to the TV to get a National Weather Service report. When the National Weather Service is unsure of the weather, they look to Skywarn - hundreds of volunteers who are trained to report ground level conditions that radar cannot detect. For 364 days of the year, volunteer Amateur Radio operators, often called "hams," affiliated with the NWS' Skywarn program provide the National Weather Service with critical, visual confirmation of major weather events. But one day a year, ARRL, the national association for Amateur Radio, and the NWS join together in recognizing all the Skywarn volunteers and light up the radio waves just for the fun of it.

The annual Skywarn Recognition Day begins on December 6 and will last 24 hours. Hams will be contacting the National Weather Service stations throughout America. But instead of passing tornado, snow and ice warnings, this time the hams will be exchanging reception reports and greetings. Last year, contacts were made in all 50 states and 40 countries during the 24 hour event.

While you do not have to be an FCC licensed Amateur Radio operator to take part in Skywarn, many of the volunteers are hams and they are most appreciated. Amateur Radio messages are able to get through to NWS offices quickly even if the phones and internet are out due to the weather. When minutes count, especially in a tornado, radio is the fastest and most certain way to get emergency messages in to the NWS offices.

The value of these reports is considerable. Skywarn volunteers are trained by NWS staff to spot and report conditions that the weather service needs to know. Because weather radar pulses go in a straight line and cannot follow the curve of the earth, conditions from hundreds of feet above down to the ground may be missed as it is "under the radar." Like the stagehands behind the curtain, the NWS and Skywarn hams quietly do the work that makes many local TV forecasters look good.
