In the DX world
In the DX world;
If you are DXCC hunting and has a card for E51WL for North Cook Island rejected, here’s some good news. According to Bill Moore at the ARRL DXCC Desk, it turns out that the operator is a native of the island and that his previous ZK1WL had previously been approved. The bottom line is that this is just a callsign change, so if you had E51WL rejected in a recent submission send an e-mail to bmoore (at) arrl (dot) org for an update to your record. (NC1L)
In DX, W5JON will be operating as V47JA from his Calypso Bay, St. Kitts, West Indies vacation home from July 9th until August 10th. Listen out for John on 160 through 6 meters using SSB, RTTY and several digital modes. He will also be using his newly issued contest call V49J in the IARU and Islands on the Air contests on SSB. Johns wife Cathy, W5HAM, may get on the air occasionally operating as V47HAM. All QSL's go direct or via Logbook of the World to W5JON.
PA3A, PD1AEG, PA8AD and PA8AN will be active from Congo September 28th to October 11th as TN5MS. They will be active on H-F Bands. QSL via PA3AWW, either direct, or Logbook of the World.
ZL2JU is currently active from Rarotonga in the South Cook Islands as E51JJU. He is operational on most of the High Frequency bands but no exact schedule of operating times is mentioned. QSL via home call.
OO9O will be on the air portable LX from Luxembourg from June 17th to the 20th. He plans to focus on 30 meter CW and PSK. QSL via home call, or electronically using eQSL or Logbook of the World.
Five operators will be active using the call will be active from Ustica Island from July 24th to the 29th signing IE9 stroke IK6JRI. They also plan to take part in the RSGB sponsored Islands on the Air contest that takes place during their stay. If you make contact please QSL via IK6JRI
Lastly, G0MGX is currently working in Qatar and has obtained a permit to operate stroke A7. He says to listen out for him during evenings and some weekends primarily using RTTY and JT65. He adds that the Qatar Amateur Radio Society has made him feel very welcome and that he is very grateful to them for the support and help they have given to him. He adds that he has provided the ARRL with the necessary documents of licensing for all his callsigns and uploads to Logbook of the World regularly. QSL as directed on the air.
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.
