Here is my map, although Google Earth decided to corrupt the file and delete 98% of the locations :\ . Here was the original story:
The county of San Mateo had a civil defense system comprised of older Federal sirens (Thunderbolts, STL-10's, Model 5T's, and 3T22's) and a few fire sirens (Model 2's and 5's). When they decided to upgrade the system, they used DSA6 (X2) sirens to cover the west coast of the peninsula and Modulator 2's for the rest of the tsunami-prone areas. Funds were running low, so they upgraded the radios on the older civil defense and fire sirens to maximize coverage. This was the siren protocol:
Tsunami watch: 3 minute alert w/voice
Tsunami warning: 3 minute wail w/voice
All clear: 1 minute alert w/voice
I am looking forwards to the next challenge, hopefully Google Earth will keep my system in tact. Thanks
