Parsons\nSent: Tuesday, January 7, 2014 7:59 PM\nTo: AMSAT-BB\nSubject: [amsat-bb] Finding yourself on the linear transponders\n\nPerhaps it’s just me, but it seems like an increasing number of operators are trying to find their downlink by speaking into their mic while tuning up and down the band, often plus or minus 20-30 kHz. Not only is this disruptive to existing QSOs, it is not the most effective way to do it. My receiver has a panadapter with a 40 KHz bandwidth, and I can see these SSB signals swishing up and down, over and over.\n\nIf you don’t have computer control of your frequency, set up a switch by which you can send a SHORT series of dits. Then don’t swish. Adjust your transmitter is steps of about 3 kHz. Send a burst of dits at low power and listen. If you don’t hear yourself, tune up or down. This way you will have an effective way to find yourself and you won’t interrupt other QSOs repeatedly. \n\nOnce you find yourself, make sure you are not interfering with an existing QSO. Then refine your tuning until your frequency is nearly right. If you are operating CW, your done. If you are operating SSB, try holding a tone generator near your mic and adjust your transmitter or receiver until the tone on the downlink matches the tone generator.\n\nThere is probably a free tone generator available for your smart phone.\n\nBetter yet, try computer control of your transmitter and receiver. You can easily find an Elmer on the air if you need help.\n\nBut, PLEASE. don’t swish!\n\nRon W5RKN\n_______________________________________________\nSent via [email protected].
