Propagation: Realtime Band Conditions Web-Site

REALTIME BAND CONDITIONS WEB SITE 

Bandconditions.com is a new experimental website designed to provide 24 hour a day, 7 day a week, 365 day a year real time band condition information to SSB, contesters and other operators interested in increasing their scores. It can also be of benefit to other Radio Amateurs to determine band conditions for nets and casual QSO's. 

This information is not based on any software predictions or any kind of satellite based readings. Instead it uses a new Ionospheric sounding method called "HF Ionospheric Interferometry" which operates very similarly to the PolSAR system used by NASA.

FCC Chairman Tom Wheeler to Lead Fight to Maintain Net Neutrality

FCC Chairman Tom Wheeler confirmed on Wednesday, February 3rd that he intends to bring wired and wireless broadband services under utility-style rules based on Title II of the Communications Act of 1934. He said Title II would bring to end the debate over how to ensure that the Internet remains open to everyone, a concept known as Net neutrality.

In an op-ed published Wednesday on Wired.com, Wheeler said the new rules will ban paid prioritization. Thats the idea that an Internet company can pay a premium to ensure that its traffic gets to the consumer faster than everyone else's.

Wheeler also said he would reinstate rules that had been part of the previous open Internet regulation, which went into effect in 2010, but was overruled last year by a federal appeals court, leading to the current situation. The previous rules banned an Internet service provider from blocking traffic or slowing down access to content on the Internet to favor their own services.

Title II of the Communications Act holds the potential to radically change how the Internet is governed by giving the FCC unprecedented authority over it. The provision originally gave the FCC the power to set rates and enforce the "common carrier" principle, or the idea that every customer is treated fairly, on telephone service. FCC Chairman Wheeler hopes to apply that principle to Internet traffic, preventing broadband providers from favoring one bit of data over another.

Net Neutrality is important in all aspects of today's society including amateur radio since more and more emerging communications technologies are dependent on it. And in the years ahead it will be even more so.

ARRL Legislative Objectives Announced

he ARRL has made public some of its legislative objectives for the coming 114th Congressional year. 

The League says that it will continue to secure passage of legislation instructing the FCC to extend the requirement for “reasonable accommodation” of Amateur Radio station antennas to all forms of land-use regulation. The League also will continue to oppose legislation leading to the reallocation of amateur spectrum, or to sharing arrangements that reduce the utility of existing allocations. Any legislation that diminishes the rights of federal licensees in favor of unlicensed emitters, or that encourages the deployment of spectrum-polluting technologies will also be opposed by the League.

Among the other objectives, the ARRL will seek recognition of the unique resources, capabilities, and expertise of the Amateur Radio Service in any legislation addressing communications issues related to emergencies, disasters, or homeland security. 

The League says it will support complementary legislative objectives of other radio communication services, particularly the public safety and scientific services that require spectrum access and protection from interference for noncommercial purposes that benefit the public. 

Support will also be given to legislation authorizing the FCC to appoint an electrical engineer or scientist as an additional staff member to ensure the Commissioners have adequate access to technical expertise when making decisions.

The ARRL continues to oppose “distracted driving” legislation that does not clearly define the class of devices included in the regulation, so as to exclude two-way mobile radio transmitters or receivers used by Amateur Radio licensees.

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.
