Like you I am rather new to CW contesting only being involved to any
extent the past 4 years or so. Until this past Field Day all I had
done was search and pounce and typically on my TS-830S I rolled the
VBT up to narrow things as much as possible. I have only the Kenwood
500 Hz filter in the 8.8 MHz IF (I should put better filtering
in...). On Field Day the past few years I had the opportunity to use
an FT-890 with a 250 Hz filter and it really allows one to slice
through the closely packed stations.
This year's Field Day I ran (HA! called CQ and worked stations slowly
was more like it!) for the first time and found the 250 Hz filter way
too tight. I wished for a 500 Hz selection but had to make do with
the stock SSB filter. Time will tell, but without close QRM I think
I'd prefer a slightly wider filter for running than for search and
My $.02 worth!
