Radio Propagation 101

In this video Dan Vanevenhoven N9LVS gives you the basics of Radio Propagation: including Sun Spots, Solar flux, K and A factors.

Why should you be interested in propagation? Well if you want to make those DX contacts you will need to be aware of when propagation is best for conditions to your target. One way to do this is to listen. Another is to check propagation sources such as WWV mentioned above. You can also get familiar with the propagation tables presented monthly in QST and CQ magazines. These charts will tell you when to expect the best propagation on what bands and at what time for your location to other areas of the world. An excellent source is to check the DX clusters online or by packet radio. This can give you current information about DX activity that is happening right now.

December meeting follow up

KB2TJE talking about coaxial terminals.

Thank you Joe (KB2TJE) for shearing some of your vast knowledge on cables and terminations. Joe explained how RG-8X can be dangerous for your equipment specially when using high power.

Joe also showed and explained the different connector types, their impedance and how they came out to be. It was a great presentation.

Observe a satellite’s Morse Code message today! (12/12/12)

If you live in the Eastern portion of the United States and the skies are clear you can see a student built satellite flashing LEDs in Morse Code today. But don’t worry. If you it’s cloudy or if you live elsewhere there are several other opportunities to see it in the coming days.

This is the Niwaka Fitsat-1. It was developed by students at the [Fukuoka Institute of Technology] and deployed from the International Space Station on October 4th. Included in the payload is an array of LEDs seen in the image above (click for larger image). On a set schedule these are used to flash a Morse Code message for two minutes at a time. That is what’s shown in the image on the upper right.

You can look up information on seeing Fitsat-1 in your own area using this webpage. All of the observation windows in our area require a pair of binoculars or better. We’re not sure if there is any case in which this can be seen by the naked eye.

ARRL 10m Contest This Weekend! (Dec 8-9, 2012)

Since 10M has been kind to us for the past couple of months, the contest should be interesting this year.

Another great thing about this is that people with tech licenses can operate. Even though techs are limited on 10m, most of the SSB activity is between 28.3Mhz and 28.5Mhz.

Hope to hear from you on the air, specially all of the newly licensed hams.
