    "content": "I think that crazy tuning pattern boils down to this:  If the station you \nhear is not using doppler they will appear to be going up the band.  Then a \nstation that is using doppler control may appear stationary or moving up the \nband depending upon how fast your doppler AND their doppler are updating. \nMore frequent updates are better and eliminate a bunch of tuning.  I think \nthe default is around 100 hz.  I use 20 hz.\n\nFor your own signal, I'm assuming that your are hearing yourself.  I often \nhave to tune either the uplink or the downlink as much as 1500 Hz to match \nthe uplink to the downlink.  You are right on the LSB up and the USB down. \nDon't give up, you are almost there.  Don't worry about the other stations. \nPick a open spot and tune yourself first using the CAT Tuning window.  I \nbelieve I usually have to tune the Uplink UP.  Once you do it the first \ntime, you'll get the hand of it.\n\nAlso, sometimes when I first select an SSB bird, the Downlink and Uplink \nfrequencies will be a ways off from the frequencies shown in the CAT Tuning \nwindow.  If this happens, go to the up and down buttons just to the right of \nthe Downlink and Uplink display, click the 20 up and then the 20 down.  The \nDownlink and Uplink should jump to the proper frequency.  This may have been \ncaused by my CAT delay not being high enough, but I haven't observed whether \nchanging that fixed it.\n\nJohn\nN7JK\n\nFrom: asd asd <[email protected]>\nSubject: [amsat-bb]  VO52 questions....\n\nI have been trying for a week to get into the VO52 satellite and have some \nquestions... I can hear people talking and have to constantly manually tune \nthem in in crazy patterns. One persons doppler will go up and another will \ngo down. It is like I am chasing people that are constantly changing their \ntransmit frequency and does not fit a normal doppler change. Another thing \nis that I cannot tune myself in at all. It is like I am transmitting in the \nwrong sideband. I am recieving the downlink in USB and it is my \nunderstanding that the uplink is supposed to be LSB. The program I am using \nis SatPC32 that CAT tunes an IC910H into a M2 2MCP14 - M2436CP30 both with \nright hand polarization. Just trying to get away from the FM Birds and try \nsome new ones and looking for some help to figure out what I may be \noverlooking or doing wrong.\n\n  Thanks...\n\n \n\n",
