Royal Air Force Permanent Special Event Stations

The United Kingdom’s Royal Air Force station G3ELV and the Royal Air Force Signals Museum station GB4SMH, will be operational under a permanent Special Event permit effective November 1st. Normal operating times for both locations will be 10:00 to 16:00 local time on each Tuesday and on the first Saturday of each month. 
 If you make contact, please QSL only via the bureau.

Radar Contest on November 2nd

Turning to radiosports, the 2013 RaDAR-America Contest is coming November 2nd starting at 14:00 UTC and ending at 18:00 UTC.

RaDAR stands for Rapidly Deployable Amateur Radio and the event is aimed at promoting this type of operation throughout North and South America.

This competition is open to all licensed radio amateurs. A choice is made prior to the contest to participate in one of the defined categories.

The points system is so structured as to encourage portable operation, especially moveable stations. In fact, the rules are very close to those created by the founder of the contest Eddie Leighton, ZS6BNE and the ZS RaDAR competition will take place at the same time in South Africa as it will here in the Americas.

Marcus Kessler, NX5MK, is the RaDAR-America Contest manager. The complete rules can be found at tinyurl.com/radar-america-contest. You can see a promotional video on the Amateur Radio Today page at www.sarl.org.za.

ARRL Supports FCC WRC-15

 ARRL Supports FCC WRC-15 Advisory Committee Recommendations Affecting Amateur Radio

The ARRL has expressed its support for three recommendations affecting Amateur Radio frequency allocations which the FCC’s World Radiocommunication Conference 2015 FCC Advisory Committee (WAC) has already approved. ARRL Chief Technology Officer Brennan Price, N4QX, filed comments on behalf of the League October 17 in IB Docket 04-286. The League has concluded that the WRC-15 Agenda Item 1.1 recommendation for 420-450 MHz “maintains a status quo that accommodates many users and works well.” The Amateur Service is secondary on the 70 centimeter band in the United States. At least one administration has proposed to introduce international mobile telecommunications (IMT) — cellular telephone and wireless broadband — to the bottom 10 MHz of the band, but the League said it agrees with the WAC and the NTIA that things are just fine as they stand.
“The status quo is successful and represents a success story for spectrum management,” the League said. “Introduction of IMT in the 420-430 segment of this band, as proposed by one administration, will most assuredly upset this status quo.” The ARRL pointed out that although ham radio is secondary on the band, “radio amateurs have a vested interest in maintaining their ability to use the band,” and Amateur Radio has been “a responsive and responsible sharing partner” to the band’s primary users.
For its part the WAC said, “The results indicate that for most cases, sharing between IMT-2000 base/mobile stations and the various types of radars when placed in adjacent spectrum is not feasible in the absence of mitigation.” Based on information at hand, the committee said, “it is logical to conclude that co-frequency sharing between IMT and the radiolocation service in the 420-450 MHz bands is not feasible.”
The League also said the WAC recommendation for WRC-15 Agenda Item 1.10 regarding 22 to 26 GHz “protects the only worldwide, primary Amateur and Amateur-Satellite Service allocation between 146 MHz and 47.2 GHz.”
“Sharing with incumbent services, including the Amateur and Amateur-Satellite services at 24.-24.25 GHz will require technical and operation constraints that will result in spectrum being impractical for use by the MSS [Mobile Satellite Service],” the ARRL said. The Amateur and Amateur-Satellite services are primary at 24-24.25 GHz. “Radio amateurs have been responsible stewards of a band that is difficult to use, and the WAC proposal of no change to the entire 22-26 GHz range is particularly applicable to the 24-24.25 GHz segment.”
WRC-15 Agenda Item 1.18 considers a primary allocation to the radiolocation service for automotive applications in the 77.5-78.0 GHz frequency band in accordance with a resolution adopted at WRC-12. The League suggested that the FCC support the WAC recommendations “as a base for eventual reconciliation with an NTIA position,” or that the FCC not support any position on the agenda item, “as conducted studies to not support a position more expansive than that contained in the recommendation.” The Amateur and Amateur-Satellite services are now primary in the 77.5-78 GHz band, with Radio Astronomy Service users secondary.

Canadian Amateurs Favor New MW Amateur Band

Radio Amateurs of Canada has commented in support of a proposal that would create a new secondary Amateur Radio medium-wave allocation at 472 to 479 kHz. The new 630 meter band was proposed in a Consultation released in June by Industry Canada, the nation’s radio communication regulator. It proposed numerous revisions to Canada’s table of allocations warranted in the wake of World Radio communication Conference 2012 (WRC-12). Last year the ARRL asked the FCC in 2012 to carve out the same MW band for US hams.
“RAC is pleased to see the department has included this allocation to the amateur service on a secondary basis in Canada, consistent with outcome of Agenda Item 1.23 at the World Radio Conference 2012,” said RAC President Geoff Bawden, VE4BAW, on behalf of RAC. “It is acknowledged that amateur service use of this new…band will be limited to 5 W effective radiated power relative to an isotropic radiator,” Bawden continued. In line with WRC-12, Industry Canada proposed that stations in the Amateur Service “shall not cause harmful interference to, or claim protection from, stations of the Aeronautical Radio navigation Service.”
Bawden said the addition of the MW band to the Amateur Service “will give Amateur Radio operators in Canada an opportunity to participate with other amateur operators in conducting short and long-range propagation studies using very narrowband digital techniques. Such communications will provide another path for emergency and disaster relief communications, when necessary.”
Several Canadian radio amateurs and other organizations also filed comments favoring the new MW allocation.
Bawden also offered the RAC’s support to create a 60 meter band for Canada’s radio amateurs. The allocation 5250 to 5450 kHz is not yet available to hams north of the border, and while Industry Canada did not specifically propose creating an amateur allocation there, the RAC remains optimistic.
“Based on the posted comments, we expect a favourable decision to this consultation very soon and expect an appropriate footnote will be added to this portion of spectrum [in the Canadian Table of Frequency Allocations] indicating the six spot frequency allocations authorized to the Canadian Amateur Service and any restrictions on use that may apply,” Bawden told IC.
Low-frequency experimenter Joe Craig, VO1NA, writing on behalf of the Marconi Radio Club of Newfoundland (MRCN), added that group’s voice to those supporting the creation of the 472-479 kHz band in Canada. “From 2009-2012 , we and other Canadian amateurs conducted experiments between 504 and 509 kHz in support of a domestic allocation to the Amateur Service in this portion of the radio spectrum,” Craig noted. “We have used Morse and digital transmissions on 504.1, 507.77 and 508.5 MHz and were authorised to use up to 20 W ERP. There were no reports of interference from these operations.”
Utilities in Canada and the US have opposed the addition of a secondary Amateur Radio allocation at 472-479 kHz as well as at 135.7 to 137.8 kHz. In its comments, the Utilities Telecom Council of Canada (UTCC) urged IC not to establish an Amateur Radio allocation at 472-479 kHz, saying that interference to power line communication (PLC) systems operating in that part of the spectrum is highly likely and would be difficult to mitigate, since the PLC systems would have to avoid interfering with amateur operations.
“If there was an amateur allocation at 472-479 kHz, amateurs could freely operate in close proximity to transmission lines without the utility knowing that they were there,” the UTCC said in its comments. “Utilities would probably only become aware of these operations when it was too late, because they would experience unexplained outages or mis-operation of PLC systems. Interference to PLC systems has to the potential to cause widespread electrical outages.”
Craig asserts that the utilities are using drama, conjecture and “outright inaccuracies” to support their position, even citing what he called “the unfortunate FCC decision to deny 137 kHz” to US hams. “We can hope that reason will prevail, and that the new band will soon become available to Canadian amateurs,” he told ARRL.

Australia WICIN Responds to New South Wales Brushfires

 Amateur Radio Operators who are members of Australia’s WICEN have been activated as fires rage in an area called the Blue Mountains threaten to expand. 

According to Jim Linton, VK3PC, who is the IARU Chairman Region 3 Disaster Communications Committee, already some 200 homes have been lost as wildfires rage in the Blue Mountains of the Australian state of New South Wales not far from the city of Sydney. News reports attribute one death to the wildfires. A State of Emergency has been declared for the area and fire fighters worry that up to four separate blazes could potentially combine to form a single massive fire front.

Compton Allen, VK2HRX, is the president of WICEN in New South Wales. He says that an official activation has begun, drawing on the resources of the emergency communications group. Currently the mobilization is to support the declared State of Emergency with manpower in the Lithgow area to the west of Sydney.

About 1,200 firefighters were battling blazes across the state. New South Wales Rural Fire Service Commissioner Shane Fitzsimmons said personnel had volunteered to help from all across Australia, and as far away as here in New Zealand. The ground effort is being backed with more than eighty aircraft which were dropping water and fire retardant on the flames.

VK3PC says that evacuations of tens of thousands of people are possible if hotter weather conditions combine with fire fronts already burning. This is a scenario that is literally changing minute by minute and we will have more on it in future newscasts.

Note:
WICEN in Australia is comparable to a combined RACES and ARES here in the United States.

LDG AT-600ProII AutoTuner

Time was, 100 watts was a lot of power. Today, more and more mid-sized amps with 500 watts output are becoming popular. The LDG AT-600ProII is designed for this new generation of power levels.
The AT-600ProII will handle up to 600 watts SSB and CW and 300 on RTTY (1.8 – 30 MHz) and 250 watts on 54 MHz. It features LDG’s state-of-the-art, processor-controlled Switched-L tuner. It will match virtually any kind of coax-fed antenna, including Yagis, dipoles, inverted Vs, slopers, loops, just about anything. It will typically match a 10:1 SWR down to 1.5:1 in just a few seconds. You can also use the AT-600ProII with longwires, random wires and antennas fed with ladder line just by adding a balun.
The AT-600ProII features two antenna ports with a front-panel indicator showing which is in use, and separate memory banks for each antenna. The optional M-600 4.5" analog meter shows FWD (100 and 600W scales), REV, or SWR in Peak or Average. Easy to read LED bar-graph meters showing RF power, SWR and tuner status, tactile feedback control buttons and an LED bypass indicator complete the user interface. Any power source from 11 – 16 volts DC can be used; the AT-600ProII only draws up to 750mA.
Cycle 24’s not going anywhere any time soon. If you power up, LDG’s got your back with the new AT-600ProII. Order yours today.

New Equipment Strengthens ability to Communicate after any Disaster

Sick of hearing about scientists’ prediction that  much of the northern West Coast, including Del Norte, is due for a catastrophic earthquake and tsunami?
Well, local emergency officials are far from sick of reminding you, and they continue to beef up emergency infrastructure for when “the big one” strikes.
Last weekend, a 59-foot ham radio tower engineered to withstand a large earthquake was installed at the headquarters of the Del Norte Amateur Radio Club  located at the Del Norte American Red Cross building.
“In a big disaster, ham radio has been proven to be that one  form of communication that is always the last one standing,” said Cindy Henderson, Emergency Services Manager for Del Norte County, adding that cell phone towers are likely to go down in an earthquake.
During Hurricane Katrina, ham radio was the last communication available, Henderson said, adding, “Ham radio is one of those things that is going to save lives.”

Russian Military back on 21MHz

The IARU Monitoring Service newsletter reports on a possible Russian military station that has been using the amateur radio 21 MHz band. It says that encrypted voice traffic has been operating on 21000.0 kHz on USB. Also that the in-band synchronizing signal was always audible and quite strong. The transmitter sending out these transmissions is believed to be located in or near Nizhny Tagil in Russia but its purpose is unknown. The newsletter also reports that the Russian military have also been using other frequencies in our 7, 14 and 21 MHz bands and have been operating an Over The Horizon radar between 3500 and 3800 kHz.

Solar Activity Drops to 100-Year Low, Puzzling Scientists:

Predictions that 2013 would see an upsurge in solar activity and geomagnetic storms disrupting power grids and communications systems have proved to be a false alarm. Instead, the current peak in the solar cycle is the weakest for a century.

Subdued solar activity has prompted controversial comparisons with the Maunder Minimum, which occurred between 1645 and 1715, when a prolonged absence of sunspots and other indicators of solar activity coincided with the coldest period in the last millennium.

The comparisons have sparked a furious exchange of views between observers who believe the planet could be on the brink of another period of cooling, and scientists who insist there is no evidence that temperatures are about to fall. In all fairness, Russian scientists have warned over a decade ago that the Earth will enter a mini ice age period.

New Scientist magazine blasted those who predicted a mini ice age, opening a recent article on the surprising lack of sunspots this year with the bold declaration: "Those hoping that the sun could save us from climate change look set for disappointment".

"The recent lapse in solar activity is not the beginning of a decades-long absence of sunspots, a dip that might have cooled the climate. Instead it represents a shorter, less pronounced downturn that happens every century or so," ("Sun's quiet spell not the start of a mini ice age" July 12).

The unusually low number of sunspots in recent years "is not an indication that we are going into a Maunder Minimum" according to Giuliana DeToma, a solar scientist at the High Altitude Observatory in Colorado.

But DeToma admitted "we will do not know how or why the Maunder Minimum started, so we cannot predict the next one."

Many solar experts think the downturn is linked a different phenomenon, the Gleissberg cycle, which predicts a period of weaker solar activity every century or so. If that turns out to be true, the sun could remain unusually quiet through the middle of the 2020s.

But since the scientists still do not understand why the Gleissberg cycle takes place, the evidence is inconclusive. The bottom line is that the sun has gone unusually quiet and no one really knows why or how it will last.

Swedish Amateur Radio Operators get Access to the 472 KHZ Band

As of October 1st Swedish Telecom is permitting that nations radio amateurs access to the 472 to 479 kHz band. Like in some locations the maximum radiated power is one watt as opposed to the five watts permitted by some nations.
The Swedish Telecom paper also reports that also on the same date that new rules concerning exemptions from the requirement for radio transmitters to have an operating license came into effect.

Most transmitters in Sweden still require a license but for the sake of simplicity, the telecommunications regulator may allow exceptions in cases where this is little risk of interference. One new exclusion applies to vehicle communication transmissions in the 63 to 64 GHz band. Other exemptions are associated to Radio Frequency Identification use in the 2446 to 2454 MHz range for sales and inventory control.

LADEE Spacecraft goes into Lunar Orbit

NASA's Lunar Atmosphere and Dust Environment Explorer or LADEE spacecraft fired its engines Sunday morning, October 6th, slowing it enough to be captured by lunar gravity and placing it into orbit around the Moon. Once given the green light the spacecraft will begin its mission to study the Moon's exotic and almost transparent atmosphere, which is highly affected by space weather. That information will be sent by radio back to Earth for further analysis.

Faulty Radio Communications may have led to Deaths of 19 Firefighters

An investigation into the deaths of nineteen firefighters in Arizona on June 30th has found that inadequate communication may nave played a significant role in their fate. The dead men, all members of an elite unit called the Granite Mountain Hotshots died when they were overrun by a wildfire near the town of Yarnell. Amateur Radio Newsline’s Mark Abramowicz, NT3V, takes a look at what the report has to say:
--
It is a sobering and detailed report that investigators put together to try to ascertain what happened, why it happened and to prevent a tragedy like this from happening again.

Because there were no survivors, investigators relied on recordings of radio transmissions, eyewitness accounts of fire incident managers and neighboring crews, including pilots flying tankers dropping flame retardant and helicopter pilots.

The report's key findings on communications:


"Radio communications were challenging throughout the incident. Some radios were not programmed with appropriate tone guards. Crews identified the problem, engaged in troubleshooting, and developed workarounds so they could communicate using their radios.

And, this telling conclusion:

"Radio traffic was heavy during critical times on the fire."

Did it mean the Hot Shots trying to escape to what they thought was a nearby safe zone - a ranch - weren't able to cut in on the traffic?

Here's more, quoting from the 122-page investigation report:

"Although much communication occurred among crews throughout the day, few people understood Granite Mountain’s intentions, movements, and location, once they left the black."

The black is considered a safe zone.

Quoting again from the report:

"The Team believes this is due to brief, informal, and vague radio transmissions and talk-arounds that can occur during wildland fire communications.

"Based on radio conversations, Operations and other resources had concluded the Granite Mountain IHC was located in the black, near the ridge top where they had started that morning. This resulted in confusion about the crews actual location at the time of search and rescue."

Finally, the investigative team made some key recommendations to the state of Arizona and the National Wildfire Coordination group.

Among them, increasing resource tracking, communications and real time weather information.

And, putting together an interagency task force to conduct a further analysis of what happened, as well as examining the human factors and wildland fire communications.

The report describes radio communications during the time of the fire as being very challenging. (K7DB, Yarnell Hill Fire Investigation)

Amateur Radio Operator Arrested for Impersonating a Police Office

 An Indianapolis area ham has been arrested after he was allegedly spotted pretending to be a cop at the funeral of a police officer who was being laid to rest. Amateur Radio Newsline’s Jack Parker, W8ISH, has the details:
--

News of the death of an Indianapolis police officer shot and killed while responding to a domestic dispute made headlines all last week. But, on the afternoon of his funeral another man in uniform stole the headlines. As law enforcement officers, friends, family and media gathered at the cemetery another man in blue was arrested for impersonating a police officer.

As it turns out these two men had more in common than first thought. They are both Indianapolis based Amateur Radio Operators. Arrested is 38 year old Minh Nguyen, callsign KB9WDY. He was arrested as he waited with Westside residents and other police officers as the miles long funeral procession neared the west side district headquarters when deceased officer Rod Bradway was assigned.

Rod Bradway was killed last week while attempting to save a woman and her child from an armed domestic partner. Bradways Amateur Radio call sign is KC9PFW. Authorities don’t believe the two men knew each other. The police badge and uniform was the common link to this sad commentary.

According to the arrest report, Police say Nguyen was taking photographs from a black 2012 Dodge Charger equipped with a siren, flashing lights and a two-way radio. Police found an AR 15 rifle in his car and later found guns, police uniforms and police equipment at his the home.

Police say he has had prior arrests on similar and other unusual behavior. The report said Nguyen also had “property stolen from the city of Indianapolis,” including property room slips and envelopes that the public does not have access to.

Minh Nguyen faces felony charges of impersonating a public servant and theft, which carries a sentence of six months to three years in prison. A conviction could also lead to revocation of his Amateur Radio license by the FCC if they choose to review the case.

Reporting from Indianapolis, this is Jack Parker W8ISH.

Public Radio Station Fined $12000 for 6 years of Missing Paper Work

The FCC has proposed a $12,000 fine and a shorter license renewal term for Gallup Public Radio. This based on some missing documents from its public file.
New Mexico station KGLP –FM admitted it was missing nearly six years’ worth of issues and programs lists from the file. In its reply to the FCC the station indicated it has now reconstructed the missing documents.

However the FCC’s Media Bureau said in its decision the station is still responsible for the lapse. The commission found the violations to be “extensive,” occurring for nearly six years of an eight-year license term. For that reason the agency raised the proposed monetary forfeiture from the base $10,000 to $12,000 and also granted the station a shortened, four-year, license renewal term.

Gallup Public Radio was given the usual 30 days from imposition of the fine to pay the amount in full or to file a further appeal.

D-STAR Experimental Net on 40 Meters

If you have interest in digital audio on the High Frequency bands you might want to tune your D-Star equipped transceiver to 7.215 MHz at noon UTC. This to see if you can take part in a D-Star test net operating from Australia most mornings.

The net control is Brian Farrar, VK2AH, in New South Whales who says the best contacts so far have been from his location to the city of Horsham about 550 miles away. Farrar says that net participants have tried other bands with no much success but 40 meters seems promising.

VK2AK is not only on for the net but also tries 40 meter D-Star at other times of the day as well. While operating he also monitors D-Star Reflector REF003 and does put out alerts when he is looking for D-Star contacts from his QTH down-under.

Nikola Tesla Monument Unveiled in New York

The president of Serbia has traveled to the United States where he recently unveiled the Nikola Tesla Monument at Tesla’s former laboratory in Long Island. In a press statement prior to the actual ceremony, Serbian President Tomislav Nikolic said that it was the strength of Tesla’s vision is what influences how the public speaks about Nikola Tesla with respect some 70 years after he died.
Nikola Tesla who passed away on January 7, 1943 was a Serbian-born and later inventor, electrical engineer, mechanical engineer, physicist, and futurist. He is perhaps best known for his contributions to the design of the modern alternating current electricity supply system.

For decades The Tesla Science Center has been trying to set up a commemorative museum at the site of Nikola Tesla’s old laboratory, Now those behind the project and who managed to raise over a million dollars in an internet crowd funding campaign can celebrate the fact that their goal is finally starting to become a reality.

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.
