Howard, Hours to get back on the air?
You still don't get it, do you? These systems are made to be mounted on top of *MOVING* platforms and remain aligned!! Why you think this won't work at temporary shelters and non-permanent locations is beyond me. There's no "hours to get back on line". You might have some downtime if the whole installation is knocked on it's side and someone has to go out and stand it back up!! How long would that take? I've never heard of smoke causing anything more than a temporary outage but I have heard of intense thunderstorms with lots of moisture causing problems. Unless you have an earthquake at the same time as you have massive forest fires long with heavy rain type thunderstorms I fail to see your concern with these systems. I might point out, however, that intense thunderstorms also wreaks havoc with Winlink throughput so I don't believe that would be an answer either. I've said it before and I'll say it again -- the amateur service does not and should not have a role as a telecom common carrier. Not only is it beyond the scope of what the service is allowed to be by rule, the technology available in the telecom industry is far beyond what we can provide - largely because of cost. When the amateur community can put up birds with the capacity of these satellite links, maybe we can meet what the telcom industry offers, not before. The longer the ARRL and the amateur community focuses on trying to compete with services like DirectWay the less the amateur service will have to offer. What a waste. tim ab0wr On Saturday 25 February 2006 18:33, Dr. Howard S.
