Revision of the Communications Act
The Communications Act, first written in 1934, created the Federal Communications Commission and outlined rules governing communications as it stood at that time. Over the years it has been amended on many occasions to try to keep up with emerging technologies. The Act was last updated in 1996, when the Internet was still in its infancy.
The House Energy and Commerce Committee has already begun to look into ways to bring the Communications Act into line with the needs of the 21st Century, but Pryor who is chairman of the Senate Commerce Subcommittee on Communications said the overall Senate Commerce Committee probably will not be following suit.
Critics of the current Communications Act have said that it creates what they call silos for different type of communications. That they say has posed a problem for new technologies such as Voice over Internet Proytocol phone calls that are transmitted over broadband and other Internet lines.
The House of Representatives effort to rewrite the law is expected to take multiple years, and has only just gotten started. This past January an Energy and Commerce Subcommittee held its first hearing on the issue with five former FCC chairmen in attendance.

Amateur Radio Operators Responding to Slovenia Electricity Disruption
Since January 31st Slovenia has been affected by extreme cold weather such as blizzards, heavy snow and sleet. This has caused the collapse of power lines under the weight of ice and falling trees with electricity disruptions now affecting 250,000 people at the height of the outage. The restoration of electric mains supply was being made difficult by the continuing bad weather. This has prompted Slovenia to request assistance from the European Union in the form of mobile high power electric power generators.
While there has been no wide-spread national request for communications assistance Slovenian radio amateurs are preparing to respond if required. In the meantime a number of radio amateurs have been assisting in communications operations on a local community level. This, due to problems with the mobile phone service and other radio networks falling victim to the severe weather outbreak.
The European Union Civil Protection Mechanism has asked for assistance from nearby European states with Germany, the Czech Republic and Austria providing assistance. Because of uncertainty of both weather conditions and overall communications, the Austrian teams responding to Slovenia will be carrying their own gear so as to communicate back to their home bases using Pactor and Winlink.

KD8BIG Update
I hope for those of you in the Mid-West USA have enjoyed the winter this year.
I have recorded 82.4 inches of snow at my home.
Just a couple of inches difference from the local airport about 7 miles to the South West.
Sorry for the lack of post.
I've been dealing with health issues for the last several weeks and have not been on the computer as much as I have ben on the iPad.
I can blog from the iPad but it is difficult for me to get comfortable and the touch screen is so sensitive. Having severe tremors dose not help either.
I seem to spend more time using Twitter and Facebook on the iPad.
I hope to be posting more regularly as I get over this cold/flu.
Best Regards

Cuban Hams can use 60m band
The law approved on January 20 of 2014, from the Ministry of Communications of Cuba allows the use of the spectrum between the 5418 to 5430 Khz, a continuous segment of 12 Khz, this unlike other countries that are allowing just channels.
The assignation is as a secondary users as per ITU recommendations for region 2, with the emphasis on its use in emergencies nets, as Cuba is in the path of the Caribbean Hurricanes every year and this band allows a steady communication path for all the island.
The new law sets this band for every day use, but once an official emergency is declared by the Cuban State, then the use of the band will be restricted to emergency traffic exclusively, ceasing all others kinds of use on it.
The new assignation allows SSB, CW and Digital, the former limited to PSK31 and PSK63. All ham categories of the three existent in Cuba can access the band based on a power limitations of 10W for the novices and 50W for the rest; with a note of the relaxation of this power limitation up to 100W tops for all users in emergency conditions as needed for a reliable link establishment.
The access of the hams to this band is not immediate, the process involves the request and approval for individual hams to the related Authority and the modification of the ham's licence (an in-office process of about 1 day), so the band will populate steady, but slowly.
Most Cubans hams use commercial radios with full or partial coverage of HF bands or even homebrew radios, so the "hardware" will not be a major problem, for a significant percent of Cuban hams will be a matter of setting up an antenna for this new band or simply tune in his multi-band antenna.

Horns and Booms
It is 3:49am January 22nd and I woke up to my beagle growling. At first I thought she was having a dream, then it saw her looking out the window.
I heard a horn, like a train horn from outside. I looked out several windows all sides of the house and could not determine the direction of the horn other than from the sky.
A half hour after the horn a loud boom came from under the house. It was a unique low tone boom that shook the house and awoke my daughter.
Then the horn started again for about 2 minutes.

Pacific, Missouri, has taken the First Step in Setting up a D-STAR Repeater
Selby said he was recommending the repeater instead of a single radio after he and Bob Masson, KBZ0JDY, met with Franklin County emergency management officials about what communication would be needed if a disaster occurred in Pacific and the Interstate 44 corridor. He noted that amateur radio is way ahead in how public services use radio. He also read a letter from Paul Chambers, N0BBD, the Franklin County Amateur Radio Emergency Services coordinator, who said he fully supported and welcomed the idea of a digital repeater.
Selby also displayed a small blue box with cable that he said would eliminate the need for radio anywhere in the government center. The small apparatus known in the world of amateur radio as a DV Dongle, is a duplex vocoder that connects to a computer via a USB port to provide amateur radio voice transmission capability.
Selby said he contacted St Louis and Missouri repeater councils and they also are on board with the idea. Alderman Ed Gass then made a motion to purchase the repeater, but added that a battery backup would be needed for the unit in case electricity was out during an emergency. Cost of the battery backup is estimated at about $200.

A limited number of Czech Radio Amateurs will be returning to the 5 MHz band
While originally limited to only one channel on 5260 Kilohertz, under Phase 2 those Czech amateurs issued with one of these special permits will be allowed use of six channels that are common to many other nations. These are 5288.5, 5330.5, 5366.5, 5371.5, 5398.5 and 5403.5 Kilohertz. Transmissions are limited to Upper Sideband and CW only at a power level of 100 watts Effective Radiated Power.
This experimental operation permit on 5 MHz band is allowed on a strictly secondary user basis. International Telecommunications Union rules for protection of the primary users must be observed at all times.
Those who are issued 5 MHz permits must prepare and send an experimental operation report to the Czech telecommunications regulator no later than October 31st in order that analysis of the operation on the different channels and modes can be made .

Emergency Alert System May go to the Cloud
For those who may have never heard the term, in its most basic form the Cloud is a euphemism for off-site secure data storage. This is a model of networked enterprise storage where data is accumulated in virtualized pools which are generally operated by third parties. These are mostly hosting companies that operate large data centers. Their customers are people or businesses that require their data to be hosted off site so they simply buy or lease storage capacity from them.
FEMA says that its custom-built IPAWS-OPEN has not met a slate of minimum standards, such as operating with 99.9% up time and allowing the president and other officials to alert the public about emergencies within 10 minutes. Rather it has been dogged by glitches, too many layers of technical bureaucracy and mainly insufficient storage space.
The current IPAWS-OPEN system transmits emergency messages to citizens through numerous channels, including local alert systems, traditional broadcast media, the Internet and cellphones. It also needs to be quickly expandable to new public communications systems and platforms as they are created.
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.
