    "content": "Hi Andras,\n\nI totaly agree with your point.\nTo turn the \"rudder\" a little bit more into ham radio dx direction I designed several years ago a small CubeSat sized linear transponder.\n(Just google \"LE005-R2\" and you will find it).\nThe idea was to make it off the shelve available for the Cubes, as it is quiet complex to design for students.\nSurprisingly the interrest from these Cube groups was/is very very low. \n(Most requests are from privat hams ! for using it on a mountains or balloon).\nCubeSat groups seem to prefer FM, AX25, and not to much difficult ssb stuff they can not use and test themselves.\n\nMost of these small sats are under the name off education, but in the background a huge business sector is available (just google \"Cubesat shop\" and enjoy).\nBecause of this I believe the AMSATs none-profit status is a huge disadvantage, and it is very hard to get a HEO into orbit. \n\nAMSAT should have kept the RF payload (of a big satellite), and give away some spaces to universities, sharing the ham radio payload.\nNow the spaces are given away as separate small boxes (cubesats) that all have similar RF systems (FM and 1k2/9k6 AX25).\nWhy not assemble the cubes all together as one big satellite, where AMSAT provides the common digital download payload + some extra linear transponder ???\nIn this way there is more space for university experiments, and the RF is done by people who have many experience in amateurs satellite radios.\nBut best of all is that we have our own payload added. (Some less frequencies then AO40 but possibly in a MEO/HEO).\n\nJust an idea,\n\n73 de PE1RAH, William Leijenaar\n\n> Gentlemen,\n>\n> I have spent too much money on an FT-847!\n>\n> I had better to buy a well equipped HF transceiver instead!\n>\n> There is practically no usable satellites -except for AO-7 and VO-52.\n>\n> The problem is that you can find always the same stations on them.\n>\n> F2IL is in my log about 300 times...\n>\n> Spending money on FM satellites were made according to long term plans\n> of IARU, ARRL and AMSAT which had been a dream of\n> handling emergency traffic using hand-held equipment and antenna -as far\n> as I know.\n>\n> Satellite activity is seriously declining!\n>\n> gl de ha6nn\n> Andras\n>\n",
