I hope you are all doing well and making it through the winter warm and cozy. As most are aware we did not have a meeting in January due to the incredibly cold temperatures and lack of an true scheduled meeting agenda.
I apologize that the only difference this month will be the somewhat warmer temperatures although I must admit there are some things I feel we should discuss.
We have several opportunities to help promote ourselves over the 2010 year and the first one which we have done quite well now for the past couple of years is the WAM-SAG-MAN trail bicycle trail fundraising
‘Cabin Fever’ bicycle ride in
Pott. County. It is very unfortanate that this bike ride seems to be on the same day as the
Hamfest in KC in April. I hope we can get attendees to both events and find a nice balance of supporting local event communications as well as having some folks show up at the hamfest.
Next I would like to encourage all of you to come up with ideas for meeting programs.
This means both things you are interested in as well as things you can demonstrate or talk to the group about. While we might think we may bore some of the group with some programs a nice half hour to hour program is better then having nothing for the group.
Last we have some discussion on the repeater as we have an opportunity or two that we
February 2010 should probably take advantage of. In the near future we will also attempt to wire up the tone board in a manner that will allow the tones to be turned off and on through the use of a DTMF code.
I hope to see you at the meeting and hope you will join us for dinner as well.

Solar Flux: This flux number is measured from the amount of radiation on the 10.7cm band
(2800MHz). It is closely related to the amount of ultraviolet radiation, which is needed to create an ionosphere. The lowest possible number for this solar flux is 63.75. Single hop propagation already starts at 70 in lower latitude areas. Worldwide long distance propagation (DX) may turn up already with a solar flux at 120. From experience, an average solar flux of 170 seems to be ideal for 10m-20m bands
QRP DX with good possibilities during these conditions to reach every possible part of the globe

K-index:
Geomagnetic activity indices, high indices (K:>5 or A:>20) means stormy conditions with an active geomagnetic field. The more active, the more unstable propagation with possible periods of total propagation fadeout. Especially around the higher latitudes and especially at the polar regions, where the geomagnetic field is weak, propagation may disappear completely. Extreme high indices may result in aurora propagation, with strongly degraded long distance propagation at all latitudes.
Sporadic-E is strongest during low indices. Low indices result in relative good propagation, especially noticeable around the higher latitudes, when transpolar paths may open up. Maximum K-index is 9, and the
A-index can exceed well over
100 during very severe storm conditions, with no maximum.
The ARRL often reports the Kindex from the Alaskian station where this index is known as the
College K-index. Other stations reporting K-indices include
Planetary and Boulder. In contrast, the A-indices are usually reported for the Planetary station only.
The higher the K-index, the more unstable propagation becomes, the effect is stronger at high latitudes, but weaker near low latitudes.
When storm level is reached, propagation strongly degrades, possibly fade out at high latitudes.
