    "content": "I think that people tend to wax sentimental when a new satellite goes up \nthat fails to meet their sense of what the hobby is.  I see \ngeosync/phase4 being a great boon for the entire amateur hobby.  Not \nonly does it provide a means for us to do plug-n-play radio, but it also \nallows us to use parts of the spectrum that until recently have had no \nreason for usage.  We would be able to utilize our band allocation \nrather than having them sit dormant risking reallocation by the FCC or \nother governing authority.  Not having to compensate for doppler and \nwith higher frequencies means we'll be able to fit more into what we're \ngiven and be able to \"get back to our roots\" instead of using the \nInternet as a bandaid for what we do.  (Remember those old battles about \nIRLP repeaters is not really ham radio since the long haul isn't over a \nradio link?).  Most definitely there will be extra expense unless you're \na S-Band operator already which in their case, they probably have all \nthe parts to hit 24+ghz in their junk bins.  But the ability to have \nclear radio links anywhere the footprint sits, makes for an exciting \nhobby.  Since most of us use directional antennas already, the thrill of \ntracking/tuning is still there for the existing LEO birds *and* I doubt \nby any stretch of the imagination that microsat/picosats will be going \naway for a long time.  Colleges and Universities are sending them up \nmore and more so they can teach engineering practices and be able to \nsend up new \"experiments\" that would most likely be beyond the realm of \nthe geosync/phase4 constellation.\n\nThat being said, I think the payload that goes up on the geosync/phase4 \nbirds should reflect not only the current but the future of radio since \nthey'll be sitting there for the better part of 15-20 years.  Let's not \ndwell on the past where we try to accommodate everyone from DC to \ndaylight and focus on bands/technologies that reflect the experience \nwe've gained from 50 years of space flight.  And since we don't have to \ndeal with much stationkeeping tasks, more effort can be put into \nredundant RUDAK's and better efficiency in the power budget.\n\nAny idea of where the proposed longitude locations will be and \nfootprints?  Will it be a shared antenna array?  I'd love to know the \nengineering details of the agreement.\n\nde Don - KL7EET\n\n\nMichael Tondee wrote:\n>  This is kind of along the lines of what I was thinking.

Unless of course there is some sort of cross linking in the future.  I very fondly recall AO-40 and bringing it up on my computer and seeing where the foot print was today.  Maybe it's the Europeans or perhaps the VK's, ZL's (love their accent), or maybe some JA's, (practice my Japanese).  At some time, I knew I could cover the whole planet.  I do of course believe this is an excellent opportunity, though there are a some limitations.\n>>\n>> --\n>> 73 Bob W7LRD \n>> AMSAT member 28498 \n>> Seattle\n>> _______________________________________________\n>> Sent via [email protected].
