K3 filter selection

Chris Meagher-2
Hi,
Looking to get 8 pole K3 filter for SSB contest work, to knock out close in stations, considering the 1.8MHz filter, maybe too narrow?
Suggestions based on experience much appreciated.

RE: K3 filter selection

Charly

I like the 1.8 and have ordered it for my K3.  I used a 1.8 on FT-Mark 5, FT-MP, IC-775, and IC-706 and found them useful in all cases.

Chris,

Many people like the 1.8. I have the 2.1 Inrad combo in my ol' MP.
Pretty narrow to my ears. And I can use the shift width controls to
decrease the bandwidth some more.

I ordered the 2.1 for my K3.
If I need to knock out something, I'm convinced that the DSP filtering
will make it so. Otherwise we would not need it for bandwidth
adjustments.

I have the 1.8 and like it - it's not hard to get SSB down to that and  
still hear clearly if you adjust it properly.
I always start at 2.8KHz and then bring in the filter. On LSB, start  
by adjusting the Hi cut until you've almost got to 1.8KHZ, then adjust  
the Lo cut and maybe the high cut again and what for the filter to  
switch, assuming you started with 2.7 or 2.8. Haven't tried yet on USB  
- not much around on higher bands, guess you'd work that the other way.
