are the filters just snap in ?

Yes, the 2.4 khz roofing is automatically selected when your DSP BW is 2.4
or lower. If you put the 1,8 filter in, that will come on when you go to
1.8 or lower.
I believe my son, N4YDU has a 1.8 khz filter for sale at a good price.

Right.

Ok , so I might try a 1.8 filter for ssb and this only helps if I am
narrower than 2.4kwith dsp filtering is that correct ? and if I have
the filter selection on auto it will kick on only when the dsp is below
2.4 . John

The Orion comes with a standard 2400 hertz roofing filter for SSB and a
standard 1000 hertz roofing filter for CW.

Barry,
Most of the time I'd agree with you, but as Jack described his
situation,
a
roofing filter narrower than 6 kHz (be it 2.4 or 1.8) might help. For
CW,
I generally use 300 Hz, except on 160 where a wide roofing filter helps
the DSP NR (as long as there isn't too much strong local activity).

For ssb, the dsp filtering will be sufficient 99% of the time. If
you're
a
somewhat serious ssb contester, pop a 1.8Khz filter in - otherwise,
don't
bother. Narrow roofing filters potentially help much more with cw.

Hi Ray , I have no optional roofing filters in my Orion II but have
sometimes wished for them . what filter would be my first and 2nd
choice to load up on ssb . I work ssb 75 percent of the time and am
just looking to narrow things up when needed . thanks John

Jack,
I'm not sure these are the best settings either, but here's what I
do.
To
me, AGC Slope works best at 1:10 so I leave it there. On SSB, my
front
panel AGC button is set to Prog, which translates to Hang 0, Decay
10
dB/s
and Threshold 1.00 uV. On the Filtr menu, all of the optional
roofing
filters (I have them all too) are enabled and Xtal filter is set to
Auto.
With
the DSP filter set to 2750, that would auto-select the 6 kHz
roofing
filter,
> which may be your problem. If you set the DSP filter to 2400,
that
should
auto-select the 2.4 kHz roofing filter instead.
I generally use the 6 kHz roofing filter for 160-meter CW (tnx, Bob
K8IA,
for that tip) but 2.4 kHz for SSB.
Hope this helps.

Hey Ray,
Not sure how well this is going to work. I'm at work now, just
checking
for replies via the archives on this work station.
OK, here's your answers. I have all the filters installed. It does
not
do
it on cw. It mostly occurs on 75m, at night, when lots of strong
signals
and QRM are around. And it's not like it's happening constantly,
just
occasional popping in the audio, if very strong signals are on
frequency
or nearby.
I usually keep the filter on ssb set at 2750 hz. I'm thinking maybe
I
need
to cut it below 2400, and let that roofing filter kick in. Will try
it
tonight.
And the hardware nb is off. Using nr helps, and moving the agc
slope
from
> flat to one of the other 2 settings eliminates it. But I prefer
to
keep
agc slope at the flat setting, so I'm hoping someone else has
experienced
this and found a solution other than the agc slope adjustment.
I would think that adjusting the agc menu settings (decay, hang,
threshold) would do it, but I haven't found the right combo yet.
