I'm at 6 degrees south. My manual said to turn with Diseqc to the
nearest satellite with the lowest power (in my case Sirius at 5 east)

Then I needed to turn the rotor until I got an image on my TV. To my
knowledge 19.2e on the scale must be the 19.2e satellite.

Besides: my setup worked for 3 years with a Dreambox DM500 and a MVision
receiver using USALS (Diseqc 1.3)
