[Elecraft] Real world use of 1.8 filter

[Johnny]

Don is correct. I use stock 2.7k filter in contest and 1.8 k filter when there is a bad behaved station next to my wanted multiplier. 73 Johnny

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.
