Today, Saturday March 30th was a 5th Saturday EmComm exercise across Washington State. The Seattle Auxiliary Comm. Service used this to focus on HamWAN deployments at the Sector level. As background, The City of Seattle has a very nice EOC in downtown Seattle. It has two HamWAN dishes on the roof providing redundant HamWAN backbone connectivity to two different HamWAN cell sites. Seattle ACS is organized in 6 sectors. Central West, Central East, North West, North East South West, and South East. Each sector establishes its own UHF voice net, and operates within the sector like it were a small town. Radio amateurs are dispersed at their homes, or in community emergency hubs (Parks/Community Centers). Today we fielded HamWAN at 5 of the 6 sectors, some using permanently installed HamWAN clients at amateur's homes, and other using field deployable tripods and radios in parks. Each Sector net maintained voice and Winlink connectivity with Seattle EOC, and in turn Seattle EOC maintains communications with King County and the State EOC. We also deployed HamWAN VoIP Phones, and were able to call between the EOC and Sectors by dialing 4 digit extension numbers on the phone. Winlink Telnet over HamWAN is extremely fast. In previous events we have congested our UHF Winllink RMS Gateways. This problem was eliminated with Winlink over Telnet. we also tested sending photos over Winlink with the photo reduced to 100kB size. Randy, W3RWN Seattle
