DX News

In DX comes word that JA1IST, will be on the air stroke FK from New Caledonia between February 25th and March 1st. His activity will be holiday style on High Frequency bands. QSL to his home callsign or via the bureau.

F5MNW will once again be operational stroke FR from Saint Leu between March 16th and April 8th. Activity will be on the HF bands using only CW. QSL via his home call either direct via the bureau.

F6ARC will be active stroke FG from Guadeloupe between March 11th to the 23rd. Activity will be holiday style with a focus on the 30, 17 and 12 meter bands and the lower bands using 100 watts and operating Morse only. QSL via FE1IDX either direct or via the bureau.

ZL3TE will be operational as 3D2SE from Viti Levu Island between April 11th and the 14th. His main activity will be in the Japan International DX CW Contest on April 12th and 13th. Operations outside the contest will mainly be on CW, with some digital modes. QSL to ZL3TE or electronically via Logbook of the World.

G0VJG will be active stroke J6 from St. Lucia between June 5th and the 18th. Operation is likely to be on 40 through 10 meters using SSB only. If you make contact please QSL via G4DFI.

Lastly, several sources are reporting that a multi-national team will be on a DXpedition to Malawi as 7Q7Q sometime late November. This will include an entry in the CQ World Wide DX CW Contest. At airtime this operation seems to be headed up by ZS6RJ, and will be the same group that was active as 3DA0ET last year. Look for more details to be forthcoming in future newscasts.

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.
