[QUOTE="Vipersan, post: 755341, member: 325666"] ...Hi m8 .. Its a question of whatever works best for you really .. My prefered method ..since I tend towards the western arc ...and those sats in particular. I first square up the Dish to the polar mount .. Then set the polar offset and declination roughly as specified in the manual for the assembly ... Then calculate or use the sun if its available to set the whole assembly to true South ...ie top of the arc ...which would be slightly off with regards to 1W ... fully retract the actuator ( remember mine is on the left side of the dish as I face it) .... loosen the dish and swing it westward to meet the retracted actuator ...and attach it ... Power up the Vbox and set the western limit ... drive the actuator arm ...to full extension and set the East limit ... I usually set the mechanical limit within the actuator motor assembly a couple of clicks within those limits so as not to run the motor to the endstops.. In theory I'll never reach the Vbox set limits after this .. At this point the dish should roughly track the arc .. Then its a case of driving to 1W ...chosing a transponder and peaking the polar offset for max signal ... Then driving to your extreme west satellite ..and tweaking the declination for max signal ... Then back to 1 West to repeat any max signal adjustment with the polar offset ..then back to extreme west bird and repeat again with declination adjust .. Ad infinitum...until you're happy with it .. Providing you set the True South position accurately the dish should now follow the arc ...both East and West of true south ... Remember V boxes don't contain stored positions ...so you then have to enter each sat you find manually ...and store it. Always keep a hard copy list of satellite position/counts ...for future reference ... In case anything moves ...or you simply forget. Hope this makes sense.. It may not be the best way to do it ...but its always worked for me .. You can calculate true south from tables using a compass ...but if the sun is available ...at a specific time of day ...solar noon...the shadow cast ( shortest length) is a useful tool to align with as you can mount a stick off the polar mount ...or use cross wires stretched accross the dish face as an indicator .. rgds VS ...oh ..and yes ...please post up some pictures of you newly refurbed dish .. ;) [/QUOTE]
