AEN-MAR
Every Monday night, the Arizona Emergency Net – Maricopa meets on 2 meters FM for training and exercise in the public service communication arts. We focus on preparation and readiness for public service – be it scheduled events like bike races or drills, or emergencies such as storm damage or terrorist attacks. Someone has to be ready. This net is dedicated to addressing that challenge. The Arizona Emergency Net – Maricopa also activates during threats or emergencies affecting Maricopa County

The Arizona Emergency Net - Maricopa met for a routine, training activation Monday night.
The topic was "Communication Modes"
We started the net by asking stations with multi-mode capability on simplex to check in using those radios. We had 10 stations check in with multi mode radios and a total of 28 stations check in.
Assignments were given to stations with internet capability to collect information on the invention of FM and prepare reports for the net.
Terry, KE7LPG, ran a sub-net comparing the various communication modes and reported back that Single Side Band or SSB allowed them to communicate over the greatest distances while FM gave the best signal quality.
The net also lead a great discussion on communication modes and discussed the benefits of FM, enormous fidelity, used with a repeater, and virtually immune to static crashes and lightning noise.
The way to increase your transmitted audio level on a full-quieting signal is to speak louder, speak closer to your microphone, increase your microphone gain, or switch to “wide” deviation.
Sideband offers superior range, at the cost of clarity. A sideband signal is not compatible with a repeater.
If you hear weird signals on the band, you might try switching to AM or SSB to listen in.
Thanks to KF7AJS, Mark, and KE7LPG, Terry, our Alternate Net controls.
Recordings of these nets are available at www.AEN-MAR.org. Thanks to Gary Felix, W7TXR, for providing those recordings.
Next Week's Topic: "MAKING CLEAR CONCISE WEATHER REPORTS". Reading weather bulletins (what to include, what to leave out). Interpreting weather maps to others. Web resources. Reasons why you might need to report the weather. Touch briefly on making field weather reports, such as Skywarn people do.
Donna, N7LQK and Dennis, N7NTM, volunteered for Alternate Net Control.
