According to Petr Ourdnik, OK1RP, this new permit comes as a result of
material presented by the Czech amateur radio community regarding their
initial 5 MHz operation. It also involved subsequent discussions with
the nations telecommunications regulator CTU together with the agreement
of the Ministry of Defense. As a result phase 2 of experimental 5 MHz
operations began at Zero hundred hours UTC on January 1st. This means
that a small number of 5 MHz individual permits will be issued and will
be valid until the end of 2014.
While originally limited to only one channel on 5260 Kilohertz, under
Phase 2 those Czech amateurs issued with one of these special permits
will be allowed use of six channels that are common to many other
nations. These are 5288.5, 5330.5, 5366.5, 5371.5, 5398.5 and 5403.5
Kilohertz. Transmissions are limited to Upper Sideband and CW only at a
power level of 100 watts Effective Radiated Power.
This experimental operation permit on 5 MHz band is allowed on a
strictly secondary user basis. International Telecommunications Union
rules for protection of the primary users must be observed at all times.
Those who are issued 5 MHz permits must prepare and send an experimental
operation report to the Czech telecommunications regulator no later
than October 31st in order that analysis of the operation on the
different channels and modes can be made .

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.
