Can't be as cold as it is here in Michigan about 12" of snow, put some long underware on.......I too have been having problems with
Mercury II and DG-240 90cm dish. Moved when it felt like it. It worked fine with 30' or less coax but above that I had problems. I sent the receiver to
Sadoun for testing, they didn't find any problem with it. I will probably be sending my motor in next for testing.
