As things go right now, free ku band tv India means u have to tune into two satellites,
Aligning the Dish
First u got to install the dish correctly so that it lines up with the satellite at the correct Azimuth and Elevation according to the place u live in. If ur a techie u might manage but it is best left to the professional who has equipment like a signal meter to speed up the process. Softwares like SAA or sites like Dishpointer are definitely useful for the DIY folk. One can align the dish with a compass, while keeping the set top box on the signal strength indicator.
For DD Direct you have to align with INSAT 4B at 93.5*E AZIMUTH and then bother about the elevation.
For both DD and NSS 6
I guess the best thing to do is center the dish antenna at around 94*E azimuth in between both to satellites such that the signal loss for both satellites is proportional but not too high, but the strength is still good enough so that u can tune to both satellites at the same time with minimum signal loss.The only negative would be complete loss of signal during heavy rains etc.
Tuning ur STB to receive channels
A simple way would be to do a complete or full Auto scan on ur receiver so as to get all channels if your dish is perfectly aligned. Settings being :
Mode : Free+ encrypted(will also catch zee channels which though blanked out might just be fta sometimes depending on the whims of dish tv), lnb frequency 9750 , keep 22k off, Diseq off (that is if u havent hooked it to a diseq switch) rescan again with 22k on This should give u all the fta channels both on nss and insat.
