Noble, publisher of Sacramento-based International Travel News magazine, was hospitalized about two months ago, according to Editor David Tykol.
WorldRadio was published monthly from July 1971 until the end of 2008, when Noble sold the magazine to Hicksville, New York-based CQ Communications, Inc. With its February 2009 edition, it was renamed WorldRadio Online and became the first online-only major amateur radio publication.
Noble had a long and distinguished career in communications. From 1953 to 1955 he served in the U.S. Army with a VHF radio relay unit. He went on to positions at commercial radio and TV stations around the United States, including: KTWO-TV and KATI in Casper, Wyoming; KOOK-TV, Billings, Montana; KTVB, Boise, Idaho; KERO-TV, Bakersfield, California, WOOD-TV, Grand Rapids, Michigan, and KCRA Radio in Sacramento.
During the Vietnam War, Noble was a reporter-photographer for TIME magazine and the Milwaukee Journal. He also served in the TIME-LIFE bureau in Sacramento
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.
