    "content": " Hi Keith,\nBy way of sharing my personal experience - \n\n(a) A controlled approach (aka smaller sticker shock) would be to establish the Azimuth rotor and use a fixed 30deg Elevation. It works for 90% of the passes.  \n \n(b) But the main challenge in going from a handheld ops to a motorized rotator has one (usually missed) issue - you can no longer twist the antenna for phase angle compensation.  \n \n(c) Also, a circularly polarized antenna (usually) requires a switch to change between RHCP and LHCP, for a complete setup.  \n \nI too found the Arduino based approach most flexible and cost effective.  You can review it here - \nhttps://sites.google.com/site/k6vugdiary/home/satellite-tracking-system   \nI have since, following my own advice, modified it to control an old azimuth rotor. \n \nTake your time...\n \nBest,  \nUmesh  \nk6vug  \n\n\n\n\n\n\n\n    On Wednesday, August 1, 2018, 10:48:44 AM PDT, Keith E.

I'm pretty well set with my TS-2000 and I can\nfigure out antennas, but the interwebs are a major tangle of articles about\ntracking systems, and  I'm having problems sorting out the info overload.\n\nI'm in south Texas and planning a permanent installation, so weather\nhardiness is necessary. This seems to me to rule out SatNOGs and Portable\nRotation systems. The main alternative I'm seeing is the Yaesu G-5500 (Alfa\nSpid is more than I'm wanting to spend). Where things get really murky is\nthe computer interface. The GS232A is a bit on the expensive side. There\nare many alternatives, but many are no longer in production or are\ntechnically outdated.\n\nWhat I'm looking for from the group is recommendations for Az-El rotor\nsystems and computer interfaces (I'm using SATPC32 and HRD for the tracking\nsoftware).\n\nThanks & 73,\nKeith WD9GET\n\n-- \n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\n* Keith E.
