I give up on the archive search, I never find what I am looking for in
searches.

If I set up my transmitt filter to use the 2.1 8 pole, would this create
any problems. I am wondering if this would tighten the signal to
improve my TX as I am running bearfoot.
Thanks

Tx Filter for SSB and CW and Data must be 2.7 to 2.8 kHz. Better to use TX EQ
to shape your Tx audio.

Hi Dick
I was not thinking about shaping but reducing the bandwith to
concentrate the transmitt energy. Kind of like narrow filters for CW.
I am still new to this hobby and it was just an idea that I had. Maybe
when I finish going thru the extra study guide over the holidays I will
know

Limiting the audio bandwidth via EQ will also limit the transmit bandwidth
and accomplish what you are trying to do.

Hi Barry
Do you have an recommendations for setttings when you want to
concentrate the signal for tough band conditions or dx.
Thanks

You can reduce the bandwidth by cutting lows and/or highs with TX EQ. The K3
firmware expects a 2.7 to 2.8 kHz Tx filter, and will probably display an ERR
TXF error if you select another.
Your overall objective is fine, I do this by cutting the bottom two audio TX EQ
bands to their lowest
Just so someone says it, a CW signal has no width, it's carrier only. The K3
does a fine job of generating it with a 2.7 or 2.8khz filt

Try cutting the lower 2 or lower 3 bands of TX EQ.

perfectly pure signal in any mode.

TXEQ will do exactly that. Go through the archives to see my
recommended settings for common mics.

Thanks for all the guidance gents. I just took the two lowest
frequiences to minimum for a test and wow what a difference in getting
heard in pileups and bearfoot.
I will have to spend time in working thru the best settings for me and
there are archives that I have been pointed too to read up
