Arecibo Observatory on air November 10,2013

If you are hearing this before Sunday, November 10th, then listen out on 20 meters for station KP4AO. This as part of the celebration of the 50th anniversary of the Arecibo Observatory in Puerto Rico.
The operation will be on the air from 1300 until 2000 UTC around 14.250 Mhz. A commemorative certificate will be available for those who make contacts with KP4AO. QSL to Arecibo Observatory Radio Club, HC03, PO Box 53995, Arecibo, Puerto Rico, 00612. The special event is sponsored by the Caribbean Amateur Radio Group and the Arecibo Observatory Radio Club.

DX News

JF1OCQ will be active as 5W7X from Apia, which is the capital of Samoa, between November 7th and the 14th. Operations will be on 160 through 6 meters using CW and SSB. QSL via JF1OCQ, either direct or by the bureau. E-mail requests for Bureau QSLs can be sent to jf1ocq (at) arrl (dot) net
F4FET will be active stroke as 3A from Monaco on November 11th and 12th. His operation will be on 40through 10 meters using SSB. QSL via his home callsign, direct or via the bureau.
IK7JWX has informed the Ohio Penn DX Newsletter that his DXpedition to the Island of Zanzibar scheduled for April of 2014 is has been cancelled. The reasons given are technical and logistical constraints.
members of the DX Friends will be on the air from an Andres Island as 5J0R until November 10th. Activity was slated for 160 through 6 meters using CW, SSB and RTTY. QSL via EA5RM direct. More is on the web at dxfriends dot com/SanAndres2013

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.
