Jamie etal,

M Squared has been hinting for sometime about the reliability of the 
connector. In fact, their tech service recommended to me over a year ago to 
just cut off the connector and solder it directly to the rotator cable. I 
didn't want to do that and it makes for a mess if you have to remove rotator.

When I was at the Visalia DX Convention a few weeks ago, M Squared showed 
me what they now recommend for the 2800 rotator. They have a cast box 
(about 3 by 6 by 2") that can be mounted to the tower leg, preferably at 
the base of the tower. You cut off the connectors, solder the wires to the 
rotator cable and feed them down the tower to the box. Inside the box is a 
terminal strip to connect the wires together. At least now the rotator can 
be disconnected and, if needed, you can connect your control box at the 
tower base for testing. The price is about $30-35. This would also allow 
adding MOV etc. protection at the tower base for lightning.
