In the early hours of Friday, June 11, as many as 300 campers were taken unawares when 6-10 inches of rain fell in the rugged Ouachita Mountains. The deluge caused the normally quiet Caddo and Little Missouri rivers to overflow their banks during the night. Around dawn, floodwaters barreled into the Albert Pike Recreation Area, a 54-unit campground in the Ouachita National Forest, about 75 miles west of Little Rock. Cars were wrapped around trees and children's clothing could be seen scattered across several campsites. In all, authorities said that 20 people lost their lives; 18 of the 20 victims have been publicly identified, among them eight children age 7 or younger. Eight of the 18 were from Louisiana, seven were from Texas and three were from Arkansas. The Pike County Sherriff requested the assistance of Amateur Radio operators to assist with search and rescue operations, as well as communications support, at the site. Read more here.

Public Service: California Hams Help Coordinate Off-Road Rescue

On Saturday, June 12 around 1:30 PM local time, Jim Siemons, AF6PU, of Walnut Creek, California, was checking his e-mail when he received a message from a friend who was concerned that his brother -- who, along with four friends had taken an off-road adventure along California's famed Rubicon Trail -- had not come home when expected. Siemons' friend told him that his brother's group had left on Wednesday with four off-road vehicles in an attempt to cross the Trail. Since Siemons and his friend's brother were members of the same off-roading club, his friend thought Siemons might have some information. Siemons forwarded the e-mail to several other club members; within five minutes, he received a phone call from fellow club member Jenny Ward, KI6YBQ, suggesting that he try Amateur Radio to attempt to locate the missing group. There is no cell phone coverage on the Trail and very limited official agency radio coverage, making Amateur Radio the only effective means of communication in the area. Read more here.

+ FCC News: ARRL Comments in FCC Spread Spectrum Proceeding

In response to a 2006 ARRL Petition regarding spread spectrum issues, the FCC released a Notice of Proposed Rule Making (NPRM) on March 16 (WT Docket No 10-62). The Commission is looking to amend Part 97 to facilitate the use of spread spectrum communications technologies by eliminating the requirement that amateur stations use automatic power control (APC) to reduce transmitter power when the station transmits a spread spectrum (SS) emission, as well as reducing the maximum transmitter power output when transmitting a SS emission. The ARRL filed comments on this matter on June 14, 2010. Read more here.

Attention Weather Satellite Users: FCC Seeks Information, Comments on Current Use of 1675-1710 MHz

The National Broadband Plan (NBP) recommends that the FCC should make 500 MHz of spectrum available for broadband use within the next 10 years, including 300 MHz between 225 MHz-3.7 GHz for mobile use in the next five years. The FCC's Office of Engineering and Technology (OET) has engaged in discussions with the National Telecommunications and Information Administration's (NTIA) Office of Spectrum Management to begin examining various frequency bands that may be suitable for mobile broadband use. NTIA has preliminarily identified the 1675-1710 MHz band for such use and is examining the impact on its incumbent federal users. As such, the FCC issued a Public Notice (ET Docket No 10-123) on June 4, 2010, seeking information to help better comprehend the current use of the 1675-1710 MHz band by non-federal entities and better understand its potential utility for broadband. This portion of the spectrum is utilized by weather satellites. Read more here.

+ FCC News: FCC Seeks Comments on Amateur 5 MHz (60 Meters) Allocation

In May, the FCC released a Notice of Proposed Rulemaking (NPRM) -- ET Docket No 10-98 -- proposing to amend the Part 97 rules governing the Amateur Radio Service. Specifically, the Commission looks to modify the rules pertaining to the use of five channels in the 5330.6-5406.4 kHz band (60 meters) to replace one designated channel with one that is less encumbered, to authorize three additional emission designators and to increase the maximum authorized power in this band. On June 15, a summary of the NPRM was published in the Federal Register, which started the clock on the deadline for comments. Comments must be filed on or before July 15, 2010 (30 days after publication in the Federal Register); reply comments must be filed on or before July 30, 2010 (45 days after publication in the Federal Register). Instructions on how to file comments are listed beginning on page 6 of the NPRM.

+ ARRL Field Day: Field Day Station Locator Service Returns for 2010

First introduced in 2008, the ARRL's Field Day Station Locator Service has proved a popular addition to the Field Day toolbox. This service -- an interactive map that helps amateurs or those interested in Amateur Radio find a Field Day site near them -- is free to clubs or individuals who will be operating public Field Day stations. Stations can also be listed by state or province. So far, hams in all 50 states and Puerto Rico have listed Field Day sites on the Field Day Locator. If your group would like to be a part of the Station Locator Service, it's easy to get started -- just go to the Field Day Station Locator Web site and follow the instructions (this is a different link than was printed in the Field Day packets). ARRL Field Day is the most popular on-the-air operating event in Amateur Radio. On June 26-27, join tens of thousands of Amateur Radio operators as they gather for a public demonstration of the Amateur Service.

+ On the Air: A Ham Radio Homecoming

The MIT Radio Society, W1MX, is a regular entrant in the school club category of the ARRL Sweepstakes. W1MX is the oldest college radio club in the country, and celebrated their 100th year in 2009.

Beginning with the 2010 ARRL November Sweepstakes, the prohibition against alumni operating at a school club station has been repealed. According to Ward Silver, N0AX, the goal of the rule change is to get more school clubs active for Sweepstakes and on HF. Sweepstakes is just a little over four months away -- the first and third weekends of the month. What are your plans? Wouldn't it be nice to hear the call sign of your alma mater ringing out in the middle of the Sweepstakes exchange? Sure it would!

Tom Fielitz, KC8YAK, and Andrew Temme, KE7ESD, working the 2009 ARRL Sweepstakes (Phone) from W8SH at Michigan State University.

"Entering Sweepstakes in the Multioperator category was once a staple of the fall semester's competitive atmosphere, but many high school and collegiate clubs have fallen silent or nearly so over the past decades," Silver explained. "Your school club might be interested in hosting an alumnus or two -- why not contact them? If the club station has been inactive in recent years, this would be a good way to help get activity jump-started again. To get the juices flowing, challenge a nearby club or try to beat a score from days gone by." Read more here.

+ International Perspective: Forthcoming IARU Activities at the ITU

Working Parties 1A and 1B of the International Telecommunication Union's (ITU) Study Group 1 will meet in Geneva from June 21-28. A major item of discussion will be protection of radio services from interference from Broadband over Powerline (BPL), called Power Line Communications (PLC or PLT) in Europe. The International Amateur Radio Union (IARU) has already contributed to the ITU-R report SM2158, Impact of Power Line Telecommunication Systems on Radiocommunication Systems Operating in the LF, MF, HF and VHF Bands Below 80 MHz. This report shows the acceptable criteria for degradation of the HF radio noise floor caused by BPL is defined as being 0.5 dB. Work in WP1A will concentrate on the protection of radio services from the effects of BPL in range from 80-200 MHz. Read more here.

+ Solar Update

The Sun, as seen on Thursday, June 17, 2010 from NASA's SOHO Extreme Ultraviolet Imaging Telescope. This image was taken at 304 Angstrom; the bright material is at 60,000 to 80,000 Kelvin.

Tad "The starred and stately nights seemed haughty dames in jeweled velvets, nursing at home in lonely pride, the memory of their absent conquering Earls, the golden helmeted Suns!" Cook, K7RA, reports: Sunspots disappeared for the past two days, June 15-16, which is a bit scary considering the weak solar cycle we've seen recently. In the northern hemisphere, we are just a few days from the summer solstice. Despite the lack of sunspots for the last two days of the June 10-16 week, the average daily sunspot numbers rose 2.5 points from the previous week. Geomagnetic activity peaked on June 16, with the planetary A index at 19 and high latitude College A index at 42. This should decline over the next couple of days. Look for more information, including a look at some reported 10 meter propagation from Arizona to Rarotonga, on the ARRL Web site on Friday, June 18. For more information concerning radio propagation, visit the ARRL Technical Information Service Propagation page.
