Hi,
I agree with Dan.
I haven't used a 706 but on my Yaesu FT-920 , it came from the factory with
a 2.4 kc IF filter.
I modified it to transmit with a 2.8 kc IF filter "which helped the transmit
fidelity a lot" and currently it is using the original 2.4 kc IF filter for
receive. I plan to replace the 2.4 kc IF filter with a 2.1 kc IF filter as
soon as I decide to turn loose of $125.00 plus S/H for the filter.

International Radio, Umpqua, OR
Sells great IF filters
They say
Our choices for SSB a
a.. #716 2.8 kHz (maximum audio quality; minimum selectivity)
b.. #709 2.1 kHz (we think this is the best all-purpose width unless
conditions are very crowded)
c.. #711 1.8 kHz (the contesters like this one: maximum selectivity, but
minimum audio quality)

I'm considering adding an IF filter to my 706, and am trying to decide
between the 1.9kc or the 2.8kc width for use on SSB.
Has anyone any experience with either/both?
FL-103 2.8kc
FL-223 1.9kc

Not with the 706 per se, however you basically need to decide if you want
decent quality or hi pitched un-natural voice.

2.8 is a good choice for a decent sounding SSB signal. 1.9 would be good
for digging one out of the noise.

If the 706 is switchable for those choices, get them both.
