Khrystyne Keane, <email@example.com> =========================================================== ==> 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.

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 <firstname.lastname@example.org>. Do you have a question or a problem? Send your questions via e-mail <email@example.com> 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.
