New Spectrum Awarded to Hams in France
Still with space related matters, the 2400 to 2415 MHz band is now allocated to radio stations in the Amateur-satellite service in French territories in Region 2.
Regarding the 1.2 GHz band the national society questioned if Europe’s new Galileo Global Positioning satellite system may call into question the future of this allocation for use by ham radio. Galileo downlinks across 1260 to 1300 MHz band. France’s telecommunications regulator said that it would review this matter and provide a response at some future date.
These changes are the result of a meeting between French telecommunications regulator the Autorité de Régulation des Communications Électroniques et des Postes and the French national amateur radio society R-E-F that was held on March 7th. Discussions also covered the possibility of a future amateur band across the whole of 1.8 to 2.0 MHz spectrum and possible allocations at 5.5 MHz and 70 MHz. The R-E-F report also noted that the regulatory body has also shown an interest in ARISS school contacts which both groups believe have a high educational value.

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.
