[QUOTE="John, post: 1089322, member: 175005"] Ok - Covid-19 boredom setting in a bit now so needed something to do My 2.2 Elite C-band rig is a good 3 mtr off the ground to the lnb position so if any micro tweaking has to be done on the feed assembly it either means the whole rig has to be cranked down OR take the dish across to it's extreme East position with motorised elevation taken to the max down position - this then makes the feed reasonably easy to reach off a small ladder.... all in all , a right ball ache. One of my niggles was that i was never too sure or satisfied that i had the scalar in exactly the right position- i was only 99% sure. So - time to have a rummage in the bits and bobs scrap box that contains years and years of collected bits and bobs to knock up something to make the scalar motorised from the shack under observation from the dish feed cam. What i knocked up certainly 'aint pretty but it works extreemly well as the scalar ring can be moved in millimetres or less increments and it's performance for optimum scalar position on the feed barrel is monitored on the dish cam and also the Promax FSM - and didn't have to buy anything new really. The items used out of the junk box are: - a telescope focus rack and pinion with it's control box, a small 12volt angled geared motor and some home brew brackets. There was already a spare 2 core cable running from the shack to the dish position that then got used for the scalar focus motor.
