A google search of "longitude latitude poughkeepsie NY" showed you are located at 41.70N(latitude) and 73.92W(longitude). Your true south satellite is always your longitude location, that means SBS 6 is very close at 74 degrees and is your true south satellite. You can look at Lyngsat to check out satellite locations. Set your motor elevation to your latitude, roughly 42 degrees. You'll need to figure out the dish elevation and the compass heading to point the dish.

Set your receiver on SBS 6 and use a hot transponder. The only one I get here is the
Ohio News Network. 11741H SR 6.616. Good luck, let us know how you are making out.
