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

4-4-2011 - Guard channel operations - WB4ZKA


28 stations participated in the net.  Of those, 22 (79%) were able to use a UHF guard channel. 

UHF-capable stations went to 446.050 simplex to see who they could contact during the net.  It was an exercise of doing a simplex "guard channel" thing while on a VHF net.
A standard simplex channel that everyone "guards" or monitors can be incredibly useful on public service events, disasters, and even just around town.  The public services (police, fire, etc.) call this simplex function "car-to-car" or "tactical" channels for local messages that don't need to go through the dispatch ("net", in our case) channel.
Amateurs with VHF/UHF radios can participate on a VHF net without missing any traffic on the UHF guard channel.
We also exercised using tactical call signs.  It's been a while since we've done that on Monday night, and was a new concept to some folks.  Good!  This is the place for such learnings.
Thanks to Bill, K7WWM, serving as Alternate Net Control. 
Next weeks topic will be "BLENDING REPEATER AND SIMPLEX OPERATIONS".  What can you do when you can't reach the net repeater but can hear it?
Kevin, KE7VIN, will be Net Control.  Bill, K7WWM, volunteered as Alternate Net Control.
