DX News

In DX, YL2GM is currently reported on the air from Sao Vicente Island as D44TYL. Activity has been mainly 20 and 15 meters SSB. The length of his stay is unknown. QSL via YL2GM.
HB9EYP will be on the air from Zanzibar between November 2nd and the 9th possibly using the call 5H3JJ. Activity will be QRP on 20 through 6 meters with 10 watts into a Windom antenna from a beachfront location. QSL via his home callsign either direct, via the bureau or electronically using Logbook to the World.
Members of the DX Friends group will activate San Andres Island as 5J0R from November 1st to the 10th. Operations will be on 160 through 6 meters using CW, SSB and RTTY. Visit their Web page at

for more information and QSL via EA5RM.
DL7VOA will be active as 6V7D from Senegal between November 29th and December 7th. His operation will be mainly on CW, with some SSB, on 40 through 10 meters. QSL via DL7VOA.
A group of operators from India will be operating from the Lakshadweep Islands from November 20th to the 10th of December as VU7AG and VU7KA. They will be active on 160 through10 meters using CW , SSB and RTTY. QSL via W4VKU
  A team of 8 operators will be active from the rare Banda Besar Island between November 10th to the 15th. Callsigns have not been announced yet but operations will be on 40 through 10 meters using CW and SSB. Look for more details to be forthcoming at http://oc157.blogspot.co.uk/

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.
