It does not matter if that frequency is the tx or the rx, always the higher of the two.\n\nrr on my daughter...boys, school, clothes and cd's take her money hihi\nshe went off to university last week...maybe if she gets a fully automated station at school we would hear from her more often.\n\n73...bruce\n\n-----Original Message-----\n\nFrom: \"Roger Kolakowski\" <[email protected]>\nSubj: Re: [amsat-bb] Re: A051\nDate: Fri Aug 24, 2007 6:03 pm\nSize: 1K\nTo: \"Marc Vermeersch\" <[email protected]>, \"'Bruce'\" <[email protected]>, \"'AMSAT-BB'\" <[email protected]>\n\nBruce (a very influential and integral part of AMSAT) projected:\n\n> As doppler affects\n> both frequencies, they should both be corrected using computer control\n\nBut computer control may not be available in DX, mobile, remote, battery\npower, \"minimalist\" or \"emergency\" situations.\n\nComputer control is an advancement, it should not keep people off the\nsatellites. If everyone spouts \"computer control\" you will never give a\n\"newbie\" the satellite bug.\n\nI have a QSL card from Bruce's teen age daughter...Bruce, do you think she,\nas a bona fide Ham Radio operator, has the personal finances available,\nassuming she is saving for college, to put together a computer controlled\nSSB satellite station? Why should she be kept off the linear birds because\nshe can only afford an inexpensive 435 SSB/CW rig and a preamp,\ndownconverter for 2 meters to 10? (BTW my 2 kids are licensed also but they\nare 28 and 24 respectively.)\n\nI believe there should be correction, but it does not HAVE to be \"computer\ncontrolled,\" it has to be on a best effort basis.\n\nRoger (first Satellite contact on RS-6 & multi contacts keying an FM rig)\nWA1KAT\n\n\n----- Original Message ----- \nFrom: \"Marc Vermeersch\" <[email protected]>\nTo: \"'Bruce'\" <[email protected]>; \"'AMSAT-BB'\" <[email protected]>\nSent: Friday, August 24, 2007 7:36 AM\nSubject: [amsat-bb] Re: A051\n\n\n>\n> > this method of correcting for doppler is an incorrect practice.
