The two meter band in the United Kingdom may soon be a megahertz larger.
This as United Kingdom telecommunications regulator Ofcom publishes a
consultation on the release of around 6 MHz of VHF spectrum in the 143
to 169 MHz band, which has been returned for civil use.
--
For ham radio operators in the U-K, the key point of the Consultation is
the proposal to permit temporary access of the spectrum from 146 to 147
MHz for amateur radio use, until or unless it might be needed by
Business Radio or other services. Should additional spectrum be needed
to meet those operational requirements, Ofcom says that it will re
remove the temporary ham radio allocation.
Amateur Radio use of 146 to 147 MHz will be on a non-protected and
non-interference basis with any other service. There will also be some
geographical restrictions to ensure that there is no interference to
neighboring countries. Authorization to use this spectrum by U-K hams
will be by an individual Notice of Variation to an applicant’s amateur
radio license.
A notice of Variance is the equivalent of a Special Temporary Authority
while an Ofcom Consultation is about the same as an FCC Notice of
Proposed Rule Making here in the United States.

Responses to the Ofcom proposals in the Consultation by United Kingdom citizens are due by May 26th.

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.
