[Elecraft] Real world use of 1.8 filter

[Don Wilhelm]

Keith,

Under what conditions do you use the 2.1 kHz filter and wish for the
1.8? I ask because the use of a narrow SSB filter makes tuning more
critical (and more care is required to get an intelligible signal).

So if you are doing search and pounce in a contest, the extra time to
tune with the 1.8 kHz filter may be enough to miss the contact entirely
- you would br better off putting up with the QRM and letting the brain
do the filtering.

But if you are carefully tuning a DX station during a pileup, then the
1.8 might be of some assistance if the pileup is not well behaved - in
that case you would have more time to do careful tuning.

I am curious about the difference between the 2.1 khz and the 1.8 khz but not enough to make the purchase decision at this point.  I think it is probably not an educated recommendation to make but I will do so anyway.  I really like the 2.1 khz filter and end up using it all the time and it does make a difference to me in more crowded band conditions.  I have not owned it long enough to comment on how it performs in contests.  Maybe then I will be wishing I had the 1.8 khz filter instead of the 2.1 khz filter.
