Please log in for more thread options Amateur Radio is part of our local and state Emergency Operations Center procedures, and tested at least as often as required by the rules at the nearby nuclear power plant. AFAIK, they only operate 2 meters, most of which depends on repeaters. -- Paul | |||||||||||||||||||||||||

Please log in for more thread options 2m or 144-148 Mhz is the frequency [band] you see mostly in use. It [has] a good combination of building penetration and slight over the horizon coverage as well as [short] antenna length. However, extensive use is [also] made of UHF, 430 to 450 Mhz. See http://www.saralink.ca/sara-pic.htm for a system that covers much of the province of Alberta. There are UHF hubs in the major centres. Other bands such as 222 to 225 Mhz are used by the Amateur Radio Emergency Services (ARES) in Alberta. But just as important are the lower frequencies that allow the signal to go hundreds or thousands of miles. This allows amateurs to get messages outside the affected area such as during the Quebec ice storm or the tsunamis. These require more setup and physical space due to the longer antennas required. Radio amateurs operating on 2m make extensive use of repeaters. However these are vulnerable to hurricanes, ice storms and power outages. So the amateurs train in simplex or direct station to station contact as well. Coverage is not as good of course. The various ARES groups in cities also generally have mobile repeaters which can be placed on high spots in the affected areas or to replace antennas on towers that have been damaged or destroyed. These mobile repeaters are also deployed in support of many special events on the fringes of current repeater coverage such as marathons, triathlons, car rallies and similar annual events.

Please log in for more thread options I oversee a local Ham Radio ARES/RACES team at the county level. 2 meters is there because it is popular, but we also have HF, 440 mhz, 6 meters, and the ability to send and receive slow speed e-mail and small attachments over HF Pactor or 2 meter packet from locations without Internet service, jacking into an area that still has Internet service. See http://www.winlink.org for more info. Steve N2UBP | |||||||||||||||||||||||||

Please log in for more thread options Here in the Inland Empire (Riverside/San Bernardino) most agencies work with the local Hams during an emergency and training is going on all the time. In LA County there are Ham Radio operators working in the Emergency Communications Centers 24/7 even when there are no emergencies. I believe Riverside is the same, but as I said I'm pretty much out of it now. I just dug my old 10 meter portable out to see how it worked, I put new batteries and it appears to be as good as it was the last time I used it some 20 years ago. -- The Only Good Spammer is a Dead one!!
