However, LilacSat's transponder is only active some days, as you\ncan see. Also, NO-44's health is not very good and its giving several\nproblems. I hear that, for instance, it shouldn't be used over Region 1\n(Europe and Africa) to prevent it from transmitting on 144.390 (which is\nused by meteor scatter people).\n\n> 2.\tAt the top of the AMSAT satellite status page, there is a blank line\n> for satellite status, with reports.  Is this a new satellite that is not yet\n> turned over to operations?\n\nThat's probably nothing. Reports not correctly labelled or a software bug.\n\n> 3.\tWhich of the following satellites will work when NOT illuminated?  I\n> remember AO-7 and NO-44 won't, and AO-73 will, but not sure about SO-50,\n> FO-29, NO-84, AO-85, XW-2F.\n\nAO-7 only works when illuminated. NO-44 I'm not sure about its status.\nAs I said, it's not doing so well. The rest of them work fine in eclipse.\n\nAlso, note that on weekdays AO-73 will only run high-power (300mW)\ntelemetry when illuminated and transponder and low-power telemetry when\nin eclipse. In weekends it's always transponder and low-power telemetry.\n\n> 4.\tWhat is the best way to tell if a satellite is illuminated?  Could\n> be before sunrise at my QTH if the bird is east, or after my sunset if the\n> bird is west.  How can I tell?\n\nIn fact a satellite can be illuminated even if it is over the nigh side\nof Earth, because it high above the surface. For instance, AO-7 will\nspend about half of the year always illuminated.\n\nIf your satellite tracking software doesn't tell you (Gpredict) does,\nyou could use Illum by DK3WN. Look for it here:\nhttp://www.dk3wn.info/software.shtml\n\n> 5.\tI need more info on APRS.  I set it up to relay my position from my\n> car on 144.39 many years ago, but Bob Bruninga has often said APRS capable\n> of so much more.\n\nYou can send text messages, get weather reports, send \"objects\" for\nlocations of interest, etc. Take a look at http://aprs.fi to see what\nother people are doing with APRS.\n\n> a.\tIs satellite APRS helpful just for isolated locations, for relaying\n> information?\n\nNot sure. Probably most people use it just for playing. You can do valid\nDX QSOs by satellite APRS if that's your thing, also.\n\n> b.\tHow long does the satellite transmit the information packet (what is\n> the lifetime of the packet?)  \n\nThe satellite retransmits the packet almost immediately after receiving\nit and only one time. This is the same as a terrestrial digipeater does.\n\n> c.\tWhat if the amount of packets to be transmitted by the satellite\n> takes longer than the visibility of the satellite at my QTH?  I won't hear\n> certain data, right?  \n\nAs I said, the satellite doesn't do store and forward, but rather\nrepeats the packets immediately. What happens if many people are using\nthe satellite is that the packets will collide and won't be heard by the\nsatellite. The same happens with a terrestrial digipeater.\n\n> d.\tWhat is everyone else using satellite APRS for?\n\nAs I said, probably just for fun, but perhaps there are people in remote\nlocations using it for relaying some useful data (although you probably\ncould also use HF APRS for that).\n\nHope you find this useful. Probably other people can add more\ninformation or another point of view.\n\n\n73,\n\nDani M0HXM/EA4GPZ.\n\n",
