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

4-5-2010 - Guard Channel Operation - KE7VIN



36 stations participated in the net. Of those, 21 (58%) had a guard channel set.

The need for an Alternate Net Control station was demonstrated when life happened to the scheduled Net Control station and he was unable to start the net. We discussed what a guard channel is and what it can be used for. While the net was taking check-ins three stations from different parts of the valley changed to the guard channel and passed simplex traffic. They demonstrated that traffic can be passed on a guard channel, even if relays are necessary, while the net carries on as usual.

A guard channel (a simplex frequency apart from the net frequency) can be useful to pass traffic that is not relevant to most of the net to and from net control without interrupting the net. It can also be used for tactical communications when near Net Control. A simplex frequency can also be used in the field for communications at a localized incident to keep the net frequency free. A side note: it is best to use a different band (like 70 cm if the net is on 2 m) to decrease the possibility of desense on the net radio while using the Guard Channel. This hint brought to you by El Tour de Phoenix Net Control.

Welcome to first time net participants:

Jason, KF7IJB

Mike, KF7GOA

Steve, W6SDM

Robert, KI6MGK
Please check in as whenever you can. We all benefit for each others' knowledge. If life gets in the way, don't worry if you need to miss a week. We'll still be here. Remember; Life, love, and people, then everything else.

Thanks to Bill, K7WWM, for putting together the script and log. With the well prepared script it was easy to step in and assume Net Control responibilities. Thanks also to Dan, W7SRP, for acting as Alternate Net Control. And thanks to Dennis - KE7EJF, Judy - K7JLF, and Steve - W7KMG, for demonstrating the use of a guard channel.

Next weeks topic will be "MacGyver 101". One of our strengths as Ham Radio operators is our flexibility when things go wrong. What will you do if you antenna fails, or your radio lets the smoke out, or any other number of things that can happen during a public service event or emergency? Check in next week and test your skills, and learn how others handle problems. Virgil, K7VZ, will be Net Control.

Andrew, KF7CCC, volunteered as Alternate Net Control.
