    "content": "\nHello folks,\n                Linear satellites are getting a bit thin on the ground lately arn't they - and what with the (hopefully) temporary demise of AO-51 (a software reload) there's not much a satellite operator can do other than to make an appearance on AO-7 or VO-52.\n\nTherefore, I wrote the following 'missive' as a suggestion, so, instead of whinging, you can can get off your bum and chuck together a small interface for your FM handheld and try some QRP operating - you just might surprise yourself.\n\nWhile predominantly aimed at European operators I added this to the amsat-bb because there are a *LOT* of potential 'linear' folks among the FM operators \"over there\".\n\nDo please take the time to learn a little about power budgets and  aerial gain etc.\n\n73 John.   <[email protected]>\n..................................................................................................\n\n\n\nOBSERVATIONS FROM NORWAY                                                           \nLA2QAA                                                        \n14 January 2008\nAn experiment,\n\n\n\nAs many of us are aware, the average age of Hams is creeping up and satellite \noperators are no exception - we're heading faster toward 'extinction' as opposed \nto distinction.\n\n\n\nThe much debated 'no code' exam - (to encourage more younger amateurs) - has, \nIMHO - had the complete opposite effect. With MSN and SMS why bother with \nAmateur Radio? ... the answer would be ... to do something you *CAN'T* do on \nyour pet computer.\n\n\n\nSo what can be done to turn around the negative trend of this sad state of \naffairs?. I don't pretend to have all the answers ... however ...\n\n\n\nOne possible solution is to attract more of the 'FM only' amateurs onto linear \nsatellites, to explore other means of communication so that they're not 'stuck' \nwith the boring 'single user' solution.\n\n\n\nThe usual fly in the ointment excuse, here is ...  \"but I haven't got any gear \ncapable of for example CW\" ... which is of course an excuse that is as weak as \n'hiss' with a capital P. \n\n\n\nIt is perfectly feasible to modulate an FM signal by switching on and off the \ncarrier ... some people have used the PTT button to achieve this but  a more \nelegant solution is to feed a controlled CW signal directly into the microphone \ninput of an FM  ... A.K.A.  MCW modulation.\n\n\n\nAhh! ... anti-social behaviour you say, sending 'FM' on a linear satellite - due \nto the power budget, since FM is a 100% duty cycle mode ... \n\nBUT !!! ... if one were to QRP by 25% as well as increase the aerial efficiency \nby 25% - (or any permutation giving the same results) - one would *NOT* be \n'hogging' any more of the available transponder power than one normally would on \na linear satellite.\n\n\n\nRemember, the difference between a satellite signal at the horizon and at TCA  ( \ntime of closest approach) - is quite dramatic ... (not that many people bother \nto regulate their power for ... \"enough to do the job\" ... or, as Bill used to \nsay ... \"Tis' vain to do with more, that which can be done with less\".\n\n\n\n(\"Bill\" = William of Occam 1347).\n\n\n\nRegular users of AO-7 will be aware that while activity has increased this last \n12 months in the afternoon and evening passes, the morning passes are still for \nall intents and purposes devoid of any signal at all.\n\n\n\nThe increased use of AO-7 is most likely due to a lack of other 'linear' \nsatellites, VO-52's apparent lack of activity is most probably due to the low \norbit which results in an increased Doppler rate and smaller footprint. AO-7 \ndoes provide for 6500km footprints on a daily basis.\n\n\n\nDue to above \"waffling\" ... I intend to conduct a few QRP FM experiments on the \nmode-B morning passes. If you happen to hear an AO-7 'woodpecker' you might like \nto try switching to FM for a moment to see if you can hear some CW.\n\n\n\nAs long as you keep your power low ... (LIMA - OSCAR - WHISKEY folks) ... QRP \nPLEASE ... you signal won't be any more detrimental than a CW or SSB one. Of \ncourse, you *WILL* have to take the bananas out of your ears and use them as \nthey were intended ... to listen !!!!!.\n\n\n\n73 John.   <[email protected]>\n\n\n\n",
