    "content": "Hi Gus!\n\nYou would have been happy with how AMSAT presented satellite\noperating at the ARRL Centennial Convention that just concluded\nin Hartford over the weekend.  We had a day-long training seminar\nlast Thursday (17 July), and we touched on the extremes for stations\ncapable of satellite operating.  We actually talked about the home\nstation first, complete with an IC-820 sitting in front of the\npresenters' podium along with a laptop running SatPC32.  We also had\na TS-790 in the room, copying the signals from the OSCAR I model that\nARRL allowed us to use for the weekend.  Later on, we talked about\nthe minimimalist extreme for satellite operating, for both FM and SSB.\nUnfortunately, we do not have audio or video recordings of the seminar,\nas ARRL advised at the start of each presentation that Connecticut state\nlaw forbade the audio or video recording of the presentations.\n\nOutside the convention center, I had demonstrations of both FM and SSB\noperating.  The SSB demonstrations, using AO-7, went off very well.  The\nfirst demonstration came at the end of the day-long training seminar on\nThursday afternoon, and we were able to work stations from coast to\n(almost) coast.  The second SSB demonstration, on Saturday also using AO-7,\nwas working out to just as successful, until the satellite switched off at\nmid-pass.  The FM demonstration we attempted on Saturday with SO-50 was not\nas successful.  We could hear the satellite, but with only 5 watts we were\nnot successful in hearing ourselves or making any QSOs. I have audio\nrecordings\nfrom the two AO-7 passes, and plan on making slideshow videos with photos\nand\nother information from the convention weekend to go along with the\nsatellite\naudio.  These demonstrations illustrated the minimalist approach to working\nsatellites, which also made the point that even working the (almost)\n40-year-\nold AO-7 didn't require a huge expenditure for equipment (I used two FT-817s\nwith my Elk log periodic antenna).  Many hams still envision a station that\ncould work the previous HEO satellites as the minimum required today, even\nwith lots of presentations given by satellite operators and the YouTube and\nother videos showing that it doesn't take a lot to do this.\n\nAn unexpected treat happened on Saturday morning.  I had planned on being\noutside the convention center for ISS passes, prepared to show off the ISS\ndigipeater, and - if a voice was heard on 145.800 MHz -\ntalk to an ISS\ncrewmember.  The first of the three workable passes from Hartford came a\nlittle while before the convention officially opened for the day at 0835\nlocal/1235 UTC.  The ISS was passing across the northern sky, with maximum\nelevation of 25 degrees. I heard only packet on 145.825 MHz, and was able\nto bounce a few packets through the ISS digipeater using a TH-D72A and Elk\ndual-band log periodic antenna.\n\nThe next pass, around \n1010 local/1410 UTC, was the best of the passes for\nthe morning - going across the southwestern sky with maximum elevation of\n\n59 degrees.  I had a radio listening to both 145.800 and\n145.825 MHz.  I\nheard nothing on 145.825 MHz, but thought I heard something on\n145.800 MHz. \n\nI started calling for NA1SS using my TH-D72A/Elk combination, and Reid\nWiseman\n(the same astronaut who was on for Field Day last month) answered my call.\nMy\naudience went crazy, and I was happy to make contact and have a nice 3- to\n4-\nminute chat.\n  I asked Reid if he might be on the microphone for the next pass\nover the eastern USA around 1200 local/1600 UTC.  He said he would try, and\nwe were outside for that as well. \n\n\nOnce we told people in the hall of the successful contact, the ARRL\nmade sure\nthere was a larger crowd outside for this pass.  Several\nminutes before AOS,\nI was out there again, this time answering lots of questions from different\npeople.  After AOS, I started calling for NA1SS, but never heard anything\non\n145.800 MHz during the shallow (maximum elevation 6 degrees) pass.\n\n\nI'm sure more will be written about the convention, especially the AMSAT\neffort\nthere.  Based on feedback from those attending the day-long seminar, and\nother\nfeedback throughout the convention, AMSAT did a great job showing off this\npart\nof amateur radio.  The Thursday seminar and Friday afternoon forums (one\nled\nby AMSAT President Barry Baines WD4ASW discussing the current state of\nAMSAT,\nfollowed by a \"how-to\" session for working the FM satellites led by Peter\nPortanova W2JV) were full, and all 3 sessions had audiences that were\nengaged\nand asking questions. \n\n\nNow back to the different discussions about the extremes for stations to\nwork\nsatellites, and FM vs. digital (and anything else) via satellite, already\nin\nprogress... :-)\n\n73!\n\n\n\n\n\nPatrick WD9EWK/VA7EWK\nhttp://www.wd9ewk.net/\n\n\n\n\n\n\n> As far as doing demos for the uneducated, broomstick waving is an\n> excellent introduction, highlighting the equipment simplicity and low cost.\n>  I do personally think that the shack-potato option might also appeal to\n> /some/ of the audience, so I hope the other end of the operations spectrum\n> is mentioned at least briefly.\n>\n>\n",
