I don't know why you don't like it, but I find ALL 1.8 filters 
pretty awful (and I have had quite a few). They really restrict 
the audio.

If yours is particularly bad, it is probably because your carrier
oscillators (BFO) are misadjusted and you are getting shifted
audio as well as narrow audio.  The Ten Tec 1.8 filter is as good
as or better than any others I have heard.  I do like the IRCI
2.1 kHz filter a bit better, but that makes sense, it is a bit
wider.
