The dish position has moved in last 2 weeks twice. using gi 920 to move 10 ft. channel master h-h motor and set h/v Azbox and pansat 9200. For example sat. amc 9@ 83 ku w9 the first setting 5994 then 5628 and now 5365 and all dish position setttings on all sats have changed I was woundering if reed switch is going bad it is a home made switch and it has been good for a year now> Things have just started acting up and the dish is tight even though it has been windy the last few weeks
