    "content": "Tom,\n\nThere was an article in the Journal a few issues back on why the various\nmanual techniques are only approximations, sometimes surprisingly bad ones.\nI think the author's call was WA4SCA.  So it does get talked about. With an\naccurate clock, and current Keps it is possible to work a full pass and\nscarcely touch the dial.  It definitely makes it easier to conduct a round\ntable.  If the transponder uses either modes L and/or S, you really don't\nhave much choice.  The change rate is just too fast for practical manual\nrunning, though VE3NPC does an amazing job.  Even FM, which is very\nforgiving is a challenge for manual tuning at those frequencies.  \n\nMy default is for full Doppler correction.  If the other station is using\nit, fine.  We can concentrate on communicating.  If not, I switch off and do\nit the traditional way.  It does provide some gentle encouragement to try a\nnew method, and gives you an opportunity to spread the word.  I am\nembarrassed at how long I stuck with paper logs amid all this technology.  I\nexperienced a lot of nostalgia when I transferred all my old satellite\ncontacts to electronic format, but I have never looked back.\n\nHang in there.  As time goes by, you will see more stations using it, as\nthey won't have to unlearn years of experience.  Just remember that it is a\nhobby, and there are many for whom tuning and pointing are an integral part\nof satellite operations.  Have fun!\n\nAlan\nWA4SCA\n  \n\n-----Original Message-----\nFrom: [email protected] [mailto:[email protected]] On\nBehalf Of Tom Schaefer, NY4I\nSent: Sunday, July 24, 2011 4:17 PM\nTo: Amsat BB\nSubject: [amsat-bb] Should I abandon full doppler correction?\n\nHi all,\n\nI just tried a nice pass on FO-29. I heard K9CIS on CW and W5BK from Texas.\nIn both cases, while I am using full doppler correction with my 9100 and\nMacDoppler, I suspect they are leaving the transmit frequency fixed as they\nboth changed frequency. K9CIS on CW was quite extreme in the Doppler shift.\nI know that this is a by-product of me using full doppler to listen to\nstations that are not, but it seems that the majority of the stations I hear\nare NOT using flu doppler. I have asked this question before, but it seems\nto be happening more frequently.\n\nShould I abandon full doppler correction? Another less black-and-white step\nis that if I hear a station moving to adjust my settings so I am not doing\nfull doppler. \n\nHas anyone ever taken a survey to see how many satellite users actually use\nfull doppler. Am I assuming more guys use computers and anyone of the\nmultiple ways to do computer control that have ben available for years? Does\nanyone ever talk about this in AMSAT circles? Sort of like the encouragement\none gives to people afraid of LOTW to try it? \"Computers in the\nshack.NEVER!\" I exaggerate but it seems that way. Then again, being a\ncomputer person and having computer capable rigs I realize I am skewed in my\nexpectations. I know there are guys working with old 271/471 pairs or even\nthe old FT726 out there. Great radios and a simple way to do it, but even\nthey have ways to do full doppler control and they have been out for 20\nyears. \n\nThanks,\n\nTom\nTom Schaefer, NY4I\[email protected]\nEL88pb \nMonitoring EchoLink node KJ4FEC-L 489389\nDSTAR Capable  APRS: NY4I-15\n\n\n\n\n_______________________________________________\nSent via [email protected].
