[ICOM] CW Filters on RTTY

[John Geiger]

Good morning to list members (or good whatever,
depending on what time you receive this message).  I
have a questions about narrow filters and AFSK.  I do
RTTY using MMTTY in the LSB position, which generates
AFSK instead of true FSK.  One nice thing about Icom
radios is that you can use the CW filters on SSB once
you figure out how to confuse the software.

Now here is my question, will a 250hz CW filter work
on AFSK, or is that too narrow.  In the 706 manual it
says that the 250hz CW filter can be placed in line
for RTTY narrow, but in the Icom 740 manual it says
the 270hz CW filer is too narrow to use on RTTY.  

So, has anyone used the 250hz CW filter on RTTY yet?
