John 'CQ and John 'RE,
Good points guys. I do have the TT 250Hz CW Filter in the 2nd IF. Which
pretty much matches what John has described. I do notice that things are
reasonable using the INRAD Roofing Filter & 1st IF 400Hz filter with the TT
500Hz 2nd IF combination.
I do use the passband tuning of the OMNI VI, but I use it mainly to tone
down the high frequency howling in the receiver audio. To be honest, it is
I think I will begin looking for a 2nd IF INRAD Narrow CW Filter and give it
I know this might offend some of the TT guys here, but I have been unable to
match the performance of my Drake/Sherwood R-4C. It has a full complement of
the Sherwood mod's and is beating my OMNI VI (opt 3) in every way.
In the mean time I am going to focus on getting VP8ORK into my logbook. It
will be very interesting to see how my VI handles the dog-pile on the VP8.
