The SSB filter does work. When using test equipment it is obvious that a
difference has been made when switching the filter in and out. For many
operators, the perception of a difference on receive is hard to make. Try
using a larger external speaker and switch the filter in and out. On
transmit, the filter also comes into play. You may have to ask a friend to
report out on the difference. I believe the biggest significance the SSB
filter plays is when using digital communication.

Thank you thery nutch for your kindly tip , I was one of those folks
!!!!!
... just 'cause never before I installed a filter ... now it works
properly
, but I do not feel great differences in receveing and sometimes
swiching
on
the filter it seems to enlarge the band , and this could be real : the
filter is 2,3kHz and without the RTX specs. are written 2,2KHz @ -6dB
.
Do
you agree with me ???? and again : is there anyone who have tested
the
CW
FILTER YF-122C ???

There is something wrong. First, be sure the filter is installed
correctly. When installed, you should be able to read the lable on
the filter (some folks have tried to put it in upside down). Be
sure
the 4 pins go to the 4 sockets. When the filter is placed in and
out
using menu #38, you should hear only a slight change in audio (more
highs and more lows with the new filter). With the filter, noise
sounds more like white noise. You will hear the difference more
with
a good external speaker. What you are experiencing is wrong. If
the
above doesn't fix it, likely you have a bad filter. But then ....

Hi OMs ,
just a technical info about the FT-817E : I bought the YF-122S
filter for the SSB , I installed but it seems to don't work : when I
select SSB OP FILTER from the menu 38 the noise go down to zero ,
and
this could be good , but the signals , also if strong , disappears
completely ; if I do the same test without the filter I obtain the
same result : when SSB OP FILTER is turned on from the menu the
noise
and the signal disappear .
Is it the radio or the filter to don't work properly ???? I hope
the filter !!!
Please answer soon
