Roger, I have an 1000MP with exactly the same problem.  So far it seems
that the change over relay might be the culprit.  That would cause a
problem on all bands as well.  A slight tap on the PTT will restore 
normality.   I observed that it would be a half day job to get that 
relay replaced, so I delayed the job for a while longer.  If ANYONE
has a better guess what might be the problem, Roger and I both would 
like to know!!    Cliff K7RR
