Hello,

I have been chasing this problem since 3.75 if my memory serves me
correctly.  The only workaround we have found is to set the base to
5.5Mbit in the sensitivity setting (Medium), and if a satellite STILL
causes the base to enter the retransmit-continuously mode, we set that
satellite to 2Mbit (Standard) and we usually eliminate these problems.

Karlnet has not yet given me any hopeful information, we are still at the
inquisitive stage.

Chris
