Mouser Electronics, a name well known in the ham radio do it yourself movement, has announced the signing of a new international distribution agreement with Coilcraft, a leading magnetic component manufacturer, across the regions of Europe, Asia, Mexico and South America. Through this partnership, announced at Embedded World in Germany, Mouser is now stocking a wide range of Coilcraft's magnetic and inductive products for immediate shipment. Coilcraft provides magnetic components including high- performance RF chip inductors, power magnetics and filters in a variety of packages and a wide range of values. Designer's kits are offered to help engineers learn the capabilities of these high-performance inductors. According to Mouser President and CEO Glenn Smith, this agreement with Coilcraft helps further his company's commitment to providing the newest products and technologies for design engineers from industry-leading suppliers. Smith adds that Mouser and Coilcraft are looking forward to a long- standing and successful partnership together.
World Amateur Radio Day is April 18th and according to the International Amateur Radio Union that sponsors the event the theme this year is Amateur Radio: Entering Its Second Century of Disaster Communications. According to the IARU announcement, the theme for 2013 of Amateur Radio: Entering Its Second Century of Disaster Communications is an excellent opportunity for amateur radio emergency communications groups to take advantage of the event to highlight the role amateur radio plays in disaster response. Among the suggestions are for IARU member societies to arrange ham radio demonstrations in public places such as parks or shopping areas. The IARU says that such demonstrations in public areas usually generate inquiries and questions from the public about amateur radio. It adds that this makes it a great opportunity to attract new people to become members of the ham radio community. The IARU notes that in 2013, April 18th is a weekday but that should not keep public activity from taking place either on the weekend before or after that date. Also, if you plan on holding a public demonstration, the IARU says not to forget to include some young people to show all ages are a part of this growing world wide public service oriented hobby. More information on World Amateur Radio Day is on the web at www.iaru.org.
The 2013 South African Radio League's National Convention and Annual General meeting will be held April 26th to the 28th at the Sulla Via Venue not far from Johannesburg. This years gathering will be hosted by the West Rand Amateur Radio Club with Kenny Neville from West Rand Astronomy Club as the featured guest speaker. If conditions are clear Neville's talk may be followed by a sky gazing party. More information, further program details and reservation forms should be on-line right now at will be available on www.sarl.org.za. The planners hope to see many ham radio operators there.

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.
