You are certainly right, a rotor, PC and computer based doppler correction are all optional.\nThere is a certain thrill in working SO 50 with a 10 W HT and a hand held arrow antenna, and pretty rewarding to.\n \nBut honestly, when you work AO-7 on SSB with your fully automated ground station - happily correcting your RX/TX frequencies in 10 Hz. intervals controlled from one laptop, and your fully automated homebrew tracking AZ / EL rotors clicking away controlled from another laptop, your full duplex 'Earth Station' FT 847 producing a crystal clear signal from a 40 year old bird limping along on ancient solar panels and all you have to do is press the PTT button - that puts a smile on your face, too :)\n \nAnderas - VK4TH\n\n\n________________________________\nFrom: Clayton Coleman <[email protected]>\nTo: Bill (W1PA) <[email protected]> \nCc: AMSAT-BB <[email protected]> \nSent: Wednesday, 29 May 2013 9:33 AM\nSubject: [amsat-bb] Re: a cheap LEO tracker for single op\n\n\nI'm not sure why a rotor or PC is needed.  I have made many contacts in the\npast two years with an Arrow antenna (hand driven) and an IC-910 (manual\nDoppler correction.)  With a little practice, it's really not difficult.\nThe trick is to practice, practice, practice.    Y\n\nOver the weekend I made contacts on all the active satellites with no PC,\nno rotor, and no big arrays.  Sure, Field Day will be a little more\ndifficult.  Be prepared.  Pick your passes wisely.  If you're on the East\nCoast don't pick a pass centered over North America.  Choose one out over\nthe Atlantic so that less stations will be in the footprint.\n\nLast year, I snuck onto SO-50 in the middle of the night with nothing but\nan Arrow and ten watts.  I'm not sure it'll be so easy this year\nconsidering that the recently published QST article will draw some fresh\nblood.\n\nI'm glad this is getting discussed now.  Maybe more stations will decide to\ndust off the gear and try contacts now rather than \"wing it\" for their 100\nbonus points.\n\nI am a firm believer in the KISS principle and also \"Train for how you will\noperate; operate how you train.\"\n\n73\nClayton\nW5PFG\n\n\nOn Tue, May 28, 2013 at 11:57 AM, Bill (W1PA) <[email protected]> wrote:\n\n> Let me ask this another way...\n>\n> Assuming minimal setup prior to each pass, can I track a LEO with a single\n> rotor well enough for QSO’s?  (single rotor control in one hand,\n> VFO/Doppler on my other)\n> _______________________________________________\n> Sent via [email protected].
