Larry and others-
  So  I went back to RF alignment on  lower  bands.  I did  get the 1 to 2mc rack peaked up and receiving the strong local signals.  Sensitivity is low  but they are there!
  Going then to Z213-  the 2nd one  shows  no peaking.  I tried 2 different cans  from other receivers,  but no change.  So I see a cap  right at the terminals of the can,  I should be able to  measure that....Russ.
