[Elecraft] Real world use of 1.8 filter

[Brian Alsop]

On the other hand,  the 1.8 KHz filter is my primary filter for SSB 
receive.  I'm mostly a CW operator and when I get on SSB it is only for 
working DX or a contest.  Fidelity is not an need.  Once the high 
cut/lot cuts are set up for the 1.8, one can easily widen the the filter 
width with width control alone to allow better copy for XYL or broad 
signals stations.

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.
