California Amateur Radio Service Net
P.O. Box 2340
Novato, CA 94948-2340
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
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.
Thanks to Steve, kc6ndc, we have a great YouTube piece explaining how the government is
trying to solve the global warming problem by attempting changing weather patterns, among
other things. The next time you see what you believe is a contrail from a plane above you
may learn that it is really the government using commercial airliners to spread heavy metals
in the atmosphere (climate engineering) and telling the public that it is condensation
from airplane engines.
According to GeoengeeringWatch.org, the governments efforts are making matters worse, and all
of this is being withheld from the public. Steve is an airline mechanic and believes the report
is correct and should be of great concern to everyone.

The Electrical Grid is Contaminated
Thanks to Steve, KC6NDC, we have a report from Eric Doolard that explains why the Electrical
Grid has become a large antenna that picks up all kinds of interference that interrupts our radio
communications. This is a growing problem that the ARRL and others have been fighting for years
and there is no end in sight.

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.

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.

Amateur Radio Parity Act of 2015
H.R. 1301 (now before Congress) would allow amateur radio operators to install their antennas on
condominiums and other building complexes controlled by homeowner associations.

electromagnetic pulse attack that would paralyze our telecommunication systems, among other things:

WLW, Cincinnati, AM Radio History
Dick, W6ZPE, has provided a link to a Web site that has the fascinating history of WLW AM
radio dating back to 1930 when the station first began operations. Imagine plate modulation
transformers that are 10 feet tall, and weigh 3,700 pounds each, and water-cooled transmitting
tubes more than 5 feet tall to broadcast a fully modulated 500 kW AM signal! How about an
800 foot vertical antenna guyed at the 400 foot level with bridge cables!

corner of the page. You will be transported into another world of vacuum tube history
including valuable information (and pictures) on the early Altec Lansing Corporation.

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.

Amateur Radio on the Internet
Now you can listen to the California Amateur Radio Service on the Internet via streaming
audio. You can also listen to other amateur radio transmissions, including your own, for
audio tests, and signal strength reports. Thanks to Bob, N7ISU, for this information.

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.
