And less we forget to mention, Bill notes that two student hams are expected to join this operation upon completion of their licensing, which will make it four operators. NC1L says that he will update this approval when he has more information.
SM6JBC and SM6GOR are on the air from Mauritius Island signing as 3B8JB and 3B8 stroke SM6GOR, respectively. They will be there until December 16th. Activity is on 20 through 10 meters operating CW, SSB, PSK31 and PSK63. QSL via their home callsigns.
F5AHO is operating stroke FR Reunion Island through December 4th. Activity is on 20, 17, 15 and 10 meters using SSB and the Digital modes. QSL via F5AHO, either direct or via the bureau.
F6ICX is active as 5R8IC from Saint Marie Island and will be there until December 15th. Operations are holiday style using CW, RTTY, and PSK63. QSL via his home callsign.
VK3XPT is operating from Raratonga and neighboring islands as E51XPT. He is on the air holiday style running only five watts on 40, 20, and 10 meters. QSL only via his home call.
OH6EI, will again show up from Aland Islands a OH0Z on all bands. No exact dates or operational times were given. QSL via W0MM.
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.
