Just a quick question.

When on CW mode using narrow filters, 500/250 I get this ringing all the
time, I'm guessing this is caused by the background noise on the bands
coming in via the narrow filters.

I operate mainly on 160/80/40/30m CW thus I am wondering if it is
possible to do something to the rig to get rid of the ringing effect ?

The rig I use for CW is a Tentec Omni VI with the roofing filter
modifications.

I also have an FT1000MP which suffers exactly the same problem, however
I don't like using it on CW as it has terrible key click problems, as
per all the Yaesu range of radios.

So, is this problem cureable or is there a radio on the market now that
doesn't suffer from this problem ?

Thanks for any help.
