According to the instructions on page 14 of the manual turning
"Nar" on or off controls either the YF-122C (CW) or the YF-122S
(SSB) filter depending on which one you have installed. I don't
have the SSB filter, but it's likely that it makes so little
difference that it is difficult to tell whether it's on or off!

If you set fuction 38 to off I presume that will turn
off the filter. Is this
correct? I guess the only reason to do that would to
verify the filter is
working...

Unlike the CW filter, the SSB filter is always on once
to set function 38.<BR>
The NAR has no effect on it.<BR>

Hello FT817 owners,<BR>
I bought my FT817 at Dayton and finally got it on the
air yesterday<BR>
(6/2). Today I went to install the 500hz IRC CW
filter which I also<BR>
bought at Dayton but it doesn't seem to be working.
Yes, I changed<BR>
menu item 38 to CW. Both the CW and OFF positions
sound the same.<BR>
When putting the filter menu into the SSB position it
sounds filtered<BR>
but it sounds like the CW is partially getting cut
off. On SSB the<BR>
signals are unintelligible with the filter set to ON
(SSB that is).<BR>
Again the SSB signals sounds the same with the filter
in the CW and<BR>
OFF positions. So it sounds like the filter may be
working but only<BR>
when menu item 38 is set to SSB, however, it doesn't
sound like any<BR>
500 hz CW filter I have ever heard.<BR>
<BR>
I'll be calling IRC tomorrow and I am sure they will
either have any<BR>
answer or will ship a new one because they have
always given great<BR>
service and stood behind their products.<BR>
<BR>
I am just wondering if anyone else experienced this
though ????????<BR>
