Listen, if no one is \ncalling or in the middle of a QSO, jump in!  Don't be afraid to throw your \ncall out.\n\nAnother thing that you should definitely consider - full duplex.  In case \nyou don't know what this is, full duplex is simultaneously listening to the \ndownlink WHILE transmitting.  This prevents a lot of useless QRM.  When you \ncall, you can not only tell if you are stepping on someone, but you can hear \nhow good/bad your uplink signal is, and you can be sure that you are getting \nthrough and not just getting stepped on.  You are even ahead of the game - \nthe TH-D72A has this feature!  All you need to do is learn how to use it. \nYou may, however, want to try a few more passes before diving into full \nduplex.  Full duplex will not do you any good if you have trouble hearing or \ntracking the birds.\n\n73!\n\nZack\nKD8KSN\n\n-----Original Message----- \nFrom: Alexander Sack\nSent: Monday, May 16, 2011 5:45 PM\nTo: Zachary Beougher\nCc: Clint Bradford ; Clint Bradford ; [email protected]\nSubject: Re: [amsat-bb] Re: Fm satellite Frequencies and Doppler\n\nOn Mon, May 16, 2011 at 5:25 PM, Zachary Beougher\n<[email protected]> wrote:\n> Alexandar,\n>\n> I am not sure how you have it programmed into the radio so far, but I \n> would\n> program 5 memory frequencies into your HT:\n>\n> (AO27)\n>\n> 436.805 (AOS)\n> 436.800\n> 436.795 (TCA - Time Of Closest Approach)\n> 436.790\n> 436.785 (LOS)\n>\n> Since AO27 switches off way before LOS, you will probably never need the\n> last frequency - 436.785 - but these would be the common frequency steps \n> for\n> a typical bird like AO51, SO50, etc.  Don't be afraid to make adjustments\n> either.

I switch to it\nthen move it to my VFO (F+VFO).  When the bird is going to approach, I\ninstantly go up 10Khz and work from there.  Its actually ridiculously\neasy to just switch down via the tuning knob (so programming above\ndoesn't really buy you much).  Typically depending on the bird's\ndoppler, I wound up finding the signal a bit lower than 10khz up (its\nnot like my AL-800 instantly picks up the signal at 5 degree\nelevation) but when it does, I'm good for the remainder of the pass.\n\nThe AO-51 FAQ page spells it out very nicely.  Knowing the polar chart\nin your head for the pass is very helpful.  It allows you to\ngracefully move with the signal as the satellite passes over you.\n\nMy biggest issue right now is knowing when to call out.  The flurry of\nfolks calling CQ on each pass where I live (FN20) makes it very hard\nto either a) not step on anyone and b) even find a window to get in.\nI will keep trying though (maybe when the weather gets a bit better on\nthe East Coast).\n\n73\n\n-aps \n\n",
