California Amateur Radio Service Net
P.O. Box 2340
Novato, CA 94948-2340
E-Mail: WA6YOC@aol.com

Established 2003

Frequency: 7.248 MHz

Monday-Friday, 11:00 a.m. to 12:00 p.m. Pacific Time

The purpose of this net is:

1. To handle emergency traffic

We listen for emergency and priority traffic during net operations. With the advent of cell phones, the Internet, satellite communications, and other high-tech systems, most emergency communications can be accommodated. However, experience has taught us that when we have earthquakes, floods, and other catastrophic events, those systems may fail. Amateur radio operators can provide emergency communications when this happens.

2. To exchange signal reports

As most amateur radio operators are aware, radio propagation changes from time-to-time often leaving certain amateur bands unusable. One day, 40 meters can be open, and it is possible to work stations up and down the Pacific Coast with no difficulty. The next day, the band can be closed to that particular region, but it is possible to work stations at a greater distance. Because band openings are not always predictable, it is helpful to listen to stations checking into a scheduled net to determine propagation.

3. To discuss technical matters concerning amateur radio

Telecommunications technology has changed dramatically over the years. Computer-based systems have replaced conventional radio equipment at an incredible pace. In addition, band allocations change, and the rules governing amateur radio operations are frequently updated. The opportunity to discuss those matters on the air helps amateurs stay informed.


Electric Utilities Cut-off Power to Customers

California has suffered an increasing number of deadly fires throughout the State and the number is expected to increase due to climate change, among other things. This means people will not have many of their communications options such as the Internet, cell phones, and so forth. This Net was founded to provide emergency communications when things like this happen. If you do not have these capabilities, now is the time to consider solar, batteries, and generators to power your station so you can provide help when it is needed. See link for details.

Magnetic Portals

According to NASA scientists, there is a link between the earth and the sun that allows tons of highly-charged particles to make the 98 million mile journey.

Emergency Power Test

On every Friday, we conduct an emergency power exercise to establish a communications network throughout the State of California (and into neighboring states) in the event of a commercial power failure or other catastrophic event. Amateur radio operators participate by using batteries, generators, solar power, and other off-grid resources. This gives us an opportunity to test and evaluate our emergency preparedness.

Batteries for Emergency Power Applications

Lou, AD7UT, has written a very informative paper explaining the differences between various batteries that are available to power your amateur radio equipment in the event of a commercial power failure.

Phase Shift Technical Paper

Lou, K4KYW, has prepared an interesting paper explaining the implications of phase shift as it relates to AC circuits. This is a very well written technical paper that will definitely help you understand this complicated subject.

Peak Envelope Power

Bob, W6OPO, has tackled the subject of PEP, and produced a paper on this often discussed measurement that is very enlightening. There are references, graphs and diagrams to help you understand his explanation. Larry, WA6LUT, has contributed to Bob's effort, and helped refine the article.

RF Exposure Compliance

When it is time to renew your amateur radio license, you will be asked to verify that your radio station meets FCC guidelines concerning RF exposure. The guidelines were established in 1997. Don, K6IOU, brought this subject to our attention recently when he forwarded information regarding this important issue. This is a test that you can perform yourself without the need for any test equipment. The University of Texas Amateur Radio Club has established a Web site that allows you to make the necessary calculations by completing a simple questionnaire. This is the entire test, and you are not required to forward the results to anyone.

Is Your Antenna a "Cloudwarmer?"

Most amateurs believe that the higher their antenna, the better. However, an article provided by Pat, W6PDD, suggests something different. In fact, antennas .1 to .25 wavelengths above ground can provide reliable communications for stations within a radius of 0-300 miles.
