[amsat-bb] G-5500 ooops

[Bob- W7LRD]

hello...it has been a bad week at the LRD compound. My 2M preamp went snafu now the G5500el rotor reads zero degrees and will not move. When the up is pressed the lights in the control unit dim ever so slightly just like the az (which works). Tomorrow (1/12) I'll tip the tower over and see what I have. I realize this is premature to put out a specific question. Hopefully it's something simple.
