This document raises three issues which can cause confusion and
operational trouble at EVN stations if not dealt with in an uniform
way. We will need correct system temperature estimates in the same
format regardless of the data acquisition rack type. The different
inherent limitations of MarkIII/IV and VLBA rack IF connections will
become more acute as dual polarization experiments are becoming more
common. Finally, a simple wiring change is described which would
alleviate the need to move VLBA rack sampler cables from MarkIII
position to VLBA position for VSOP mode support.
