I have an Omni 6+ which is used mostly for cw
operation.
I am considering an upgrade to the
Inrad 400 Hz filters since the Factory filters
are not shielded and have significant leakage around the filters, appear to
have ripple in the passband, and do not align correctly when used
concurrently in both IFs causing noticeable insertion loss.
What is the impact of the Inrad filters regarding these issues?
Any responses are most appreciated.
