Propagation Prediction for OCTOBER 2006
The present sunspot cycle, to persevere in declination. For the last months for which smoothed
sunspot numbers are available, solar activity remained practically constant between a level of 90-100.This means that solar activity this coming summer may run not on very
good conditions. Typical summertime propagation conditions are forecast for the HF amateur
radio bands during June. Optimum frequencies for DX propagation arte expected to be somewhat lower during most of the daylight hours, and somewhat higher during the late afternoon, early evening and nighttime hours, than they were earlier this spring.
Short skip openings, up to distances of at least 1900 Kms, are expected to increase considerably on all HF bands as a result of more frequent, more intense and widespread sporadic "E" ionization.
Here you can find predictions made by ON4UN for OCTOBER, maybe can help you to find out
the better conditions to work.
160M and 80M are not good option at this time of the year.
On 80 Meters High static level and few hours of darkness are also expected to restrict DX openings on this band during August, but some fairly good one should be possible on other areas NOT ON SOUTH AFRICA due that sun don't set.
On 40 Meters DX Conditions are expected to decline during this month because of a seasonally high noise level, and a fewer hours of darkness in the northern hemisphere. Some fairly good openings , however should be possible to many areas of the world during the hours of darkness and sunset and sunrise periods.
20 Meters this band is expected to remain open to one DX area or another
practically around-the-.clock during June. It should be the best Band for DX openings during
the early evening hours, through the hours of darkness and sunrise period. Exceptionally
high signals levels are expected during periods of optimum conditions. Numerous and widespread short-skip openings are expected over distances ranging between 500 Kms to 3500 kms . During late afternoon and early evening hours propagation conditions should be optimum for both short skip and DX openings, resulting in an exceptionally high level of interference.
15 Meters band should be optimum band for DX openings during much of the late afternoon and early evening hours. Good-to -excellent DX opening are forecast to most areas of the world during the daylight hours , with excellent openings expected to tropical and southern regions well into the evening hours as well.
10 Meters. A sharp seasonal decrease is expected in a DX propagation conditions on this band
during June nad the summer months.
Learn more about Propagation
I am often asked to recommend a good text on Webs on HF propagation. Where discusses theory in a relatively simple manner, and tells how to use propagation data for predicting bands openings.
In the past we've to found information on books, and Magazines. Nowadays we've internet and lot of software can help us to get lot of information about the best way we can have a normal QSO with a DX station. If you have difficulty please look for any browser and check Propagation, but look follow on some links.
If the amateur has in his shack a wealth of propagation charts or just on or two of them, he will be much better off than the other amateur who doesn't have any. By a simple connection through internet to the Institute for Telecommunication Sciences and Astronomy, you can receive regularly prediction muf's for the upcoming days and other information.

W6EL Prop predicts ionospheric (sky-wave) propagation between any two locations on the earth on frequencies between 3 and 30 MHz. There is no charge for W6ELProp when used for non-commercial purposes.Download W6ELProp v2.70 (479,795 Bytes)
First 5 stations on the log:
Unfortunately, for most of us, the ionosphere was not in usual well behaved self this year, but, although we reached the poorest conditions possible for the higher frequency bands.
A smoothed sunspot number of 105 is forecast for May and June. A seasonal decrease is forecast for DX conditions. While fewer openings are expected during both months.
DX propagation should be possible to one area of the world to another practically around-the clock on 20 meters. This should be the best band for DX propagation during the hours of darkness and through the sunrise period.
