==> GULF COAST PREPARES FOR GUSTAV

As of Friday, although Tropical Storm Gustav is still several days away
from landfall on the US mainland, disaster preparations are being rolled
out along the Gulf Coast. ARRL Leadership Officials, with the support of
the ARRL Headquarters staff, are taking measures that will facilitate
emergency communications among ham volunteers, among hams and served
agencies such as the Red Cross, and among Leadership Officials during
the expected emergency and in its aftermath. ARRL Section Managers in
the Gulf Coast states of Florida, Alabama, Mississippi, Louisiana and
Texas are marshaling resources and setting up procedures that will take
effect as the storm approaches the mainland. 

Support from the ARRL Headquarters staff includes referrals from local
and national media, shipment of Amateur Radio equipment via the Ham Aid
program, Section Manager liaison and referral of inquiries from Amateur
Radio operators. Two special Web sites are available for Amateur Radio
operators looking for information and volunteer opportunities:
<http://www.arrl.org/gustav/> and <http://www.arrl.org/gustav/vol.html>.
In addition, news will be updated on the ARRL Web site over the weekend
and early next week, as Gustav moves toward the Gulf Coast. 

On Thursday, as Gustav was slamming into Haiti and heading toward
Jamaica, WX4NHC, the Amateur Radio station at the National Hurricane
Center in Miami, activated at 12 PM EDT (1600Z). The NHC requested all
land based stations as well as ships at sea in the areas affected to
send them weather data (measured or estimated) and damage reports.

A post to their Web site stated: "If you are in the affected area and
normally monitor on a local Net on VHF, 40 or 80 meters, we would
appreciate your checking into the HWN NET or EchoLink/IRLP Net once per
hour to receive the latest Hurricane Advisories and to report your local
conditions. Please do not venture outside during the hurricane to gather
weather data."

In addition, the VoIP Hurricane Net activated Thursday at 11 AM EDT
(1500Z), according to a post by Jim Palmer, KB1KQW, VoIP-WX Net
Scheduler.

Also on Thursday, FEMA posted a news release that said, in part: "The
Department of Homeland Security's Federal Emergency Management Agency
(FEMA) is coordinating plans and preparatory activities of numerous
federal agencies in close communication with state, tribal and local
officials as Tropical Storm Gustav threatens to return to hurricane
strength prior to impacting Gulf Coast states. All residents in the
region are encouraged to make personal preparations. Information is
available at www.Ready.gov on how families and individuals can best
prepare before the storm.

"FEMA and its federal partners are in close communications with states
along its potential path in order to review plans, pre-station assets
and personnel, and respond to any request for assistance. FEMA's work
with states using a Gap Analysis tool to determine in advance of storms
where federal assistance is most likely to be needed has helped federal
and state agencies to develop pre-scripted mission assignments and other
contingency plans to help improve response and recovery efforts."

The news release also provides details on preparations now underway by
several other agencies, including the American Red Cross and the Army
Corps of Engineers.

Louisiana Governor Bobby Jindal declared a state of emergency for his
state on Wednesday, and he activated 3000 National Guard troops, with
more on call. The state of Mississippi declared a state of emergency on
Thursday. Governor Haley Barbour stated, in part: "I urge all
Mississippians to please take this storm seriously. One of the most
important lessons we learned after Hurricane Katrina was that there is
no substitute for awareness and self-help, especially in the days before
the hurricane is predicted to hit." 

==> THE SEPTEMBER/OCTOBER QEX IS HERE 

The September/October issue of QEX is out, and it is full of theoretical
and practical technical articles that you don't want to miss. 

In this issue, Mark Spencer, WA8SME, describes a VLF receiver system
that automatically logs received signal data so we can learn about some
propagation conditions such as sudden ionospheric disturbances during
Solar Cycle 24 in "SID: Study Cycle 24, Don't Just Use It." Phil
Anderson, W0XI, gives us a detailed analysis of crystal set receiver
circuitry in "A Great Teacher: The Crystal Set." Bertrand Zauhar,
VE2ZAZ, brings us another great project that goes well beyond a simple
battery charger with his "Rechargeable Battery Cycler." 

Jim Kocsis, WA9PYH, presents "Press-n-Peel Circuit Boards," a simple,
reliable way to make your own circuit boards using Techniks, Inc
Press-n-Peel Blue etch-resist material. Henry J. Rech offers some
thoughts about, "Receiver Performance Measurement and Front End
Selectivity," and Frank Witt, AI1H, describes "Optimum Lossy Broadband
Matching Networks for Resonant Antennas," in this reprint of an April
1990 "RF Design" article.

==> CHECK OUT THE SEPTEMBER/OCTOBER NCJ 

NCJ, The National Contest Journal is what everyone interested in
radiosport needs to have in their shack. Filled with the latest news
from the contesting world, NCJ is the voice of radiosport. Whether you
are new to contesting or are a seasoned pro (or somewhere in the
middle), you will find something in NCJ just for you. 

In the September/October issue, Stan Stockton, K5GO and Bob Wilson,
N6TV, provide a dialogue on "CW Skimmer: Point/Counterpoint." To go
along with this article, Pete Smith, N4ZR, talks about "So You Want to
Skim? Practical Issues in Deploying CW Skimmer in a Contesting
Environment." Eric Scace, K3NA, writes about "Distributing Receiving
Antennas" in the first of a multi-part article. If you're a top-bander,
you don't want to miss "A Simple 2-Element Vertical Array for 160
Meters" by John Barcroft, K6AM. 

Dennis McAlpine, K2SX, takes a look at "The Wacky World of State QSO
Parties," while Jon Platt, W0ZQ/m gives his take on "One Rover's View on
Propagation during the 2008 Minnesota QSO Party." Bill Santelmann, N1AU,
remembers his son in "A Tribute to my Son, Stuart, KC1F." Stu, a
founding member and past president of the Yankee Clipper Contest Club,
became a Silent Key in May of this year. ARRL News Editor S. Khrystyne
Keane, K1SFA, lets NCJ readers take a sneak peak at the October issue of
QST in "October is Radiosport Month in QST."

==> "THE DOCTOR IS IN" THE ARRL LETTER 

This week, ARRL Letter readers are in luck! The ARRL's very own Doctor,
author of the popular QST column "The Doctor Is IN," answers a question
from his mailbag:

Question -- John Hoffman, KJ4GER, of Woodstock, Georgia, asks: I am
reading the "ARRL General Class License Manual"
<http://www.arrl.org/catalog/?item=9965>. In a few places, it mentions
the 75 meter band. On my ARRL-provided "US Amateur Radio Bands" chart,
it shows an 80 meter band and a 60 meter band, but no 75 meter band.
What is the 75 meter band, and why does it not show up on the official
band chart?

The Doctor Answers -- John, 75 meters is an designation for the 3.6-4.0
MHz phone band, a portion of the 3.5-4.0 MHz 80 meter allocation. If you
convert 4.0 MHz to wavelength (300/4) you will find that the top end of
the band has a wavelength of 75 meters. 

Historically, 75 meters refers to the voice portion of the "official" 80
meter band. The term 80 meters is often used to refer to the entire
band. Most HF radios have a bandswitch position for 80 meters that
covers the entire band, not one for 75 meters. Unlike any other band,
you will rarely hear anyone refer to "80 meter phone." I cannot offer
any logical explanation for the anomaly -- perhaps someone will fill us
in on how this came to be.

If you know the answer to this question, send an e-mail to the Doctor
<doctor@arrl.org>;. Do you have a question or a problem? Send your
questions via e-mail <doctor@arrl.org>; or to "The Doctor," ARRL, 225
Main St, Newington, CT 06111 (no phone calls, please). Look for "The
Doctor Is IN" every month in QST, the official journal of the ARRL.

==>SOLAR UPDATE
Tad "Heat and haze of crimson sunsets" Cook, K7RA, this week reports: 
Our Sun is still very quiet, but last week's bulletin mentioned a new
sunspot emerging on August 21-22. Spaceweather.com showed the sunspot
number on those days as 11, which is the smallest non-zero sunspot
number. If we don't see any sunspots this weekend, Sunday will mark 42
consecutive days with no sunspots. This will also bring the 3-month
moving average for daily sunspot numbers (that we present monthly) clear
down to 1.76, the lowest on this side of cycle 23. This would be the
three month average centered on July.

The forecast for the next week is a planetary A index of 5 on every day,
indicating more of the same quiet and stable geomagnetic conditions. The
prediction for September 5 is a planetary A index of 18, probably from a
recurring coronal hole and associated solar wind.

Geophysical Institute Prague predicts quiet conditions August 29 to
September 3, and quiet to unsettled September 4.

Sunspot numbers for August 21 through 27 were 0, 0, 0, 0, 0, 0, and 0
with a mean of 0. 10.7 cm flux was 67.1, 67.6, 67.9, 67.1, 66.6, 66.9,
and 66.6 with a mean of 67.1. Estimated planetary A indices were 4, 4,
2, 4, 2, 3 and 3 with a mean of 3.1. Estimated mid-latitude A indices
were 4, 2, 2, 2, 1, 1 and 2 with a mean of 2.
