Amateur Radio Responds to Colorado Floods

Ham radio was once again a first responder as a week of torrential rainfall brought destruction to parts of Colorado. Many of these were the same areas that were damaged by a series of wind-driven wildfires earlier this year and back in 2012. At least seven people have been confirmed as killed by deadly flooding and efforts to locate more than 1,000 missing people continue.
Some of the worst flooding followed the path of the High Park and Waldo Canyon fires. The 2013 Waldo Canyon fire was the worst in the state's history burning more than 18,000 acres near Colorado Springs and destroying more than 300 homes.
Jack Ciaccia, WM0G is the ARRL Colorado Section Manager. He says that as the flood waters began arriving on Thursday, August 12th, ham radio operators were ready:
Ciaccia” “The hams in the local ARES groups reported to the regional and local county emergency operations centers and manned their positions. Plus the state Emergency Operations Center in Centennial Colorado was opened and staffed by senior ARES personnel”
The unprecedented storms dealt a heavy blow to both utilities and communications. News reports say that many cellular telephone towers have either fallen, were washed away or are simply without power. This in turn cut off wireless and broadband communications to several communities. Also destroyed have been powerlines and some landline-based telephone service. This has left ham radio as the mainstay of communications into and out of these areas.
Ciaccia: “The next thing to happen was we started hearing of evacuation centers being opened kind of spontaneously because a large building in a dry area was the only criteria. And as fast as we could we needed to get communications to them because in many of the mountain areas where these evacuation centers were there was no other means of communications”
As the operation progressed, some hams were assigned to monitor the Boulder County ARES Repeater as well as the two Mountain Emergency Radio Network Repeaters located in high altitude communities. The latter turned out to be true life savers. Again, WM0G:
Ciaccia: “We were fortunate to have some hams located in some of the remote areas which is (the result) of another project that we had created in the past year since the fires called the Mountain Emergency Radio Network. This is a small network of repeaters that the ARES hams have trained upward of 60 mountain residents and who have gotten their licenses. We then repurposed a bunch of VHF radios – both handy talkies and mobiles for them to utilize these repeaters.
“And just tonight we were told by the Fire Chief in one of those remote communities that had it not have been for that MERM repeater system that there probably would have been a lot more deaths because people were able to communicate with each other as to what was happening, where the destruction was and how to get out.”
On Monday the 16th the ARES groups received new marching orders. In addition to search assistance, evacuations, shelter communications and logistics another role has been added. That of disaster assessment:
Ciaccia: “Disaster assessment teams from the Red Cross and from the counties will be mobilizing and we have been asked to provide hams, radios and also video cameras to record video of the disaster areas. So we will be taking on that assignment as well.”
According to Ciaccia so far some 200 ham radio volunteers have been deployed in and around the various flood-stricken counties with some providing communication where no other means existed or still exists. News reports say that at the height of the flooding that the towns of Estes Park, Lyons and Jamestown were relying on ham radio as their only contact with the outside world.

Choke Balun (HomeBrew)

The balun described here is a sleeve balun, the ferrite cores are salvaged from the video leads from computer monitor leads courtesy of those friendly folk down at the local Council recycling center and were available just for the asking and is used to feed a trap dipole.

The other parts needed are :-

11.810" length of 0.7874" PVC conduit,

12 ferrite cores salvaged from computer monitor video leads,

15.75 UR213 cable,

3/4 PVC terminal box,

PVC tape,

PL259 plug,

Fibreglass resin,

Eyelet and brass termination bolts.
---------------------------------------------------------
1) Solder PL259 plug on one end and Strip insulation from coax as the hole in the ferrite is too fractionally too small then cover with single layer of PVC insulating tape for good fit.
2) Feed the 12 ferrite sleeves over the coax.
3) Trim tails to length and apply several layers of PVC tape over ferrite so it is a tight when the PVC conduit is  fitted.
4) Fit hardware to attach aerial. note electrical connections are separate to give good connection. Tape up all joints to prevent leakage of resin.
5)Fill with resin and remove tape when hardened.
6) Completed balun note solder connecting shorting of supporting loop. Completed balun has been tested to 400W as part a 48 hour contest with no problems reported.

Sun Mysteriously Goes All Quiet Just When Its Activity Should Be Highest:

Almost every measure of solar activity flatlined over the weekend. The event, though not unprecedented, is odd considering that our local star has just passed what is supposed to be the peak of its solar cycle, when activity is at its highest.
“It really underscores this solar cycle playing out as being pretty benign,” said Robert Rutledge, lead of the forecast office at the NOAA/National Weather Service Space Weather Prediction Center. “This has been by any measure a really pretty quiet cycle, and I think we shouldn’t expect the second half to be any different.”

Amateur Radio Provides Critical Communication in Colorado Flooding Response

ZCZC AG21
QST de W1AW
ARRL Bulletin 21 ARLB021
>From ARRL Headquarters
Newington CT September 16, 2013
To all radio amateurs
SB QST ARL ARLB021
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

I am glad to introduce you to QScope.org.

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.

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.
