Hello Pedro
My 2 cents worth from an old QUACK K7QQ
I agree with the wider filter width for CW, I use the TS-970 and on CW
the maxium bandwidth is 1 khz with 600 hz 400 hz 200 hz. 100 hz 50 hz
steps in the selection. 98 percent of the contest I wish that the 1 khz
was a bit wider.
On 40 meters only do I use a narrower filter and then the 600 hz .
I find many stations answering CQ's as much as 2 and even 3 khz off
Freq.
Now you have to make a choice , I personally wouldn't ever go below 500
hz with a choice of only one filter.
