[TenTec] Omni VI 1st IF Narrow CW Filter Enable?

[NL7VL]

John,

How cool! That's where I'd like to get for sure, but I'd try things
out with the 2.4khz roofing filter first (since that's what I have). I
was remarking to a friend of mine the other day how bothersome it is
to have empty filter slots in the rig ... he agreed. Don't know that I'd
lose sleep over it, but it is annoying.
