ARLB021 Amateur Radio Provides Critical Communication in Colorado Flooding Response
More than five dozen Amateur Radio Emergency Service (ARES) volunteers have deployed in and around flood-stricken counties of Colorado, providing critical communication for Red Cross shelters and state and local emergency operation centers. Recent heavy rains have caused veritable mountainside tsunamis that have caused rivers and streams to overflow their banks, ravaged roads and property and displaced an undetermined number of residents. At least three people are known to have died. ARRL Colorado Section Manager Jack Ciaccia, WM0G, says that with power cut off to affected communities and many cell telephone towers along the Big Thompson River toppled by the flooding, ham radio is providing medical and health-and-welfare traffic between evacuation centers and the EOCs.
"Every EOC is being staffed by ARES people," Ciaccia told ARRL. "Almost every evacuation center has an ARES communicator, doing either voice or packet communications between EOCs and shelters."
The isolated towns of Estes Park, Lyons, and Jamestown were or still are relying solely on ham radio for contact with the outside. Jamestown has since been evacuated. "Everybody was huddled into the high school there," Ciaccia told ARRL. He was in contact with the mayor there and trying to get the community needed resources as soon as possible. Hams in Estes Park have been working out of the EOC in the Town Hall, which is on high ground. "There's no place to go. Everything's flooded," Ciaccia said. "The only ham in Lyons was working out of an evacuation center at the local elementary school." He said the National Guard has been relocating some evacuees, as the shelter has become overcrowded.
On Saturday, September 14, US Congressman Cory Gardner (R-4) visited the state emergency operation center to express his appreciation to the Amateur Radio operators responding to the historic flooding disaster. Rep Gardner asked Colorado Section Emergency Coordinator Robert Wareham, N0ESQ, to extend his thanks to all ARES members staffing positions in the field as well.
Boulder County has deployed miniature drone aircraft carrying Amateur TV cameras to survey the affected, more remote regions, for now to spot individuals who may need to be rescued. "We're still in a search-and-rescue mode," Ciaccia said, "not really in a damage-assessment mode."
Ciaccia said the drones - a fixed-wing aircraft and a hybrid gas/electric-powered helicopter - have been transmitting ATV video via UHF to the ground and simultaneously recording the video on a memory stick. The helicopter can remain in the air for more than 5 hours at a clip, recording images for officials at the EOC to evaluate. Ciaccia said Boulder County Emergency Coordinator Al Bishop, K0ARK, owns Reference Technology, the company providing the drones.
Ciaccia said that during the past year the Boulder County ARES team created the Mountain Emergency Radio Network (MERN) on its own time and money and put up two repeaters - one at Allenspark and another in Gold Hill. "The intent was to start educating people in the mountain regions to become hams," Ciaccia said. Some 65 individuals have gotten their licenses, and the team provided each with a radio. "Those radios and those people - they became the eyes and ears for their communities," Ciaccia explained.
As power was lost, the only remaining means of communication were the two repeaters operating on propane-powered generators. "The system worked," Ciaccia added, "and we were able to utilize it for emergency communication purposes." Those communities have since been evacuated.
News media accounts citing the state Office of Emergency Management say 19 Colorado counties remain under a high threat of flooding. These include Boulder, Arapahoe, Weld, Park, Jefferson, Larimer, Clear Creek, Adams, Douglas, Broomfield, Gilpin, Denver, Logan, Morgan, Washington, El Paso, Teller, Pueblo and Elbert.
State authorities are warning residents in the hard-hit counties to stay off the road. Interstate 25 from the Wyoming line to Denver has been closed, along with part of Interstate 70.

QScope.org : Free online statistics and charts application for logs
http://www.qscope.org/
QScope.org is an online application that provides statistics and charts from HAM Radio logs.
Registration and access to the website are free.
While some features are designed with contesting in mind, most of the statistics will be useful for DXers and DXpeditions.
You just import your ADIF 2 or Cabrillo logs into QScope database and then browse the statistic and charts pages. The application allows for exporting your results in PDF and to share the web links to the charts you produced with your friends.
QScope permit you to create as many containers as you want and import as many logs as you need into them, so you can classified or aggregate the data the way you want.
QScope offers informations like* :
- Number of QSOs, Operating Time
- Unique callsigns worked, unique DXCCs entities, CQ and ITU Zones
- Average and Maximum QSO Rates over periods of 10, 30 and 60 minutes
- Activity Map showing which band, mode, operating position was more productive during a contest
- Charts with number of QSOs per unique callsign, band, mode or operator
- Charts with number of Points per unique callsign, band, mode or operator
- Charts with number of QSOs per CQ and ITU Zones
- Charts showing hour by hour, the Number of QSOs and Points, Number of new CQ and new ITU Zones worked, Number of new DXCC entities and new Prefixes worked
- Charts with Operating Time per band, mode or operator with parameter for pause duration
- Charts showing minute by minute how much was your QSO Rate for your whole log, per operator or per band, with parameter for the sample duration from 5 minutes to 60 minutes
- Charts with Maximum QSO Rates per band, mode or operator with parameter for the sample duration from 5 minutes to 60 minutes
* Note that the informations you can display depend on the data available in your logfile. ADIF logs containing more details than Cabrillo.
The beauty of a web application (have I said cloud computing?) is that more features and statistics can be easily added on the go and will benefit all users without need to download and install any new software. Of course improvements suggestions are welcome.

US & Canada Agree on New Border Spectrum Sharing Measure
In the way of fixed services, the FCC, the U.S. National Telecommunications and Information Administration and Industry Canada struck a sharing agreement governing 71 to 76, 81to 86 and 94.1 to 95 GHz. This is intended to facilitate deployment of fixed services within the border area. Such services include backhaul for mobile broadband networks, high-speed wireless local area networks and broadband Internet access over high bandwidth point-to-point links.
At 454.6625 to 454.9875 MHz and 459.6625 to 459.9875 MHz a Statement of Intent allows for creation of a nationwide digital system covering the sharing and coordination of spectrum for general aviation air-to-ground services. It provides for sharing of spectrum when operations are located within distances ranging from roughly 300 to 360 miles of the common border.
With regard to specialized mobile radio services at 896 to 901 and 935 to 940 MHz, the new arrangement governs the sharing and coordination of within roughly 60 miles of the common border and simplifies the criteria for permitting secondary users in the band. This is intended to enable more efficient use of the spectrum while protecting primary users. This particular agreement called Arrangement U may become part of a larger treaty or replacement agreement governing services operating above 30 MHz. The operational provisions of this arrangement will be applied on an interim basis pending further review. (RW, FCC, Industry Canada)

Louisiana Adopts Alert FM Statewide
According to the release, Louisiana’s Senator Mary Landrieu was an early supporter of the broadcast-based emergency alert systems. She is quoted as saying that with Alert FM, Louisiana has implemented a reliable method of distributing life-saving information to the citizens. She added that the dependability of broadcast transmissions can make the difference between life and death during an emergency.
As previously reported here on Newsline, Alert FM is an emergency notification system that delivers messages from state, local, and private sector officials to citizens, schools, businesses, and first responders using the Radio Data System or R-D-S sub- carrier of local FM radio stations. Messages are originated by designated officials and are then transported from a secure web-based portal to the data sub-carrier via GSS Net which is a secure satellite data delivery system. These alerts and messages are then received by FM stations and re-transmitted to Alert FM equipped receivers or to cell phones that have both active FM chips and properly installed software.
More about the Alert FM system is on line at alertfm.com. (Radio Weekly)
CHANCE OF STORMS
NOAA forecastesrs estimate a 65% chance of polar geomagnetic storms on August 10th when one and perhaps two CMEs are expected to hit Earth's magnetic field. The incoming clouds were propelled from the sun by a flurry of erupting magnetic filaments on Aug. 6-7. High-latitude sky watchers should be alert for auroras.

ARRL says no to Encrypted Amateur Radio Communications
As we previously reported, earlier this year the FCC accepted for filing a Petition for Rulemaking from Don Rolph, AB1PH, designated as RM-11699 and put it on public notice. In it Rolph suggested that an additional exception to Part 97.113 be made to permit encrypted communications when hams are participating in emergency services operations or related training exercises which may involve information covered by medical privacy requirements or other sensitive data. This could include logistical information concerning medical supplies, personnel movement or any other data designated by Federal authorities managing relief or training efforts.
But on July 8th the ARRL filed to oppose the AB1PH rules change request. The ARRL says that in its view there is no factual or legal basis for the assumption that encryption of transmissions is necessary in order to continue and enhance the utility of amateur radio emergency and disaster relief communication. The ARRL also characterized as erroneous the assumption that encryption of certain information may be required under the provisions of the Health Insurance Portability and Accountability or HIPPA Act.
The ARRL is not alone in this view. Several other commenters on RM-11699 have also pointed out that the restrictions imposed by HIPPA can be overlooked in time of a dire emergency.

HOW TO READ PROPAGATION NUMBERS
The A index [ LOW is GOOD ]
- 1 to 6 is BEST
- 7 to 9 is OK
- 11 or more is BAD
Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.
A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
SFI index [ HIGH is GOOD ]
- 70 NOT GOOD
- 80 GOOD
- 90 BETTER
- 100+ BEST
The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.
Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.
K index [ LOW is GOOD ]
- 0 or 1 is BEST
- 2 is OK
- 3 or more is BAD
- 5 is VERY VERY BAD
The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.
A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
