Warren,
Good, I didn't have time to try that.?
Though a lesser filter from a different radio convincedme it was
relays and layout.
However while it confirms bad layout it didn't test the relay contact
part of the layout issue.? We need that to confirm if the open contact
capacitance (isolation) will corrupt the filter performance.
The give away is the fact that the filter parts and characteristics are
good but blow by is a significant part of the problem.
