Has anyone any experience with either/both?
FL-103 2.8kc
FL-223 1.9kc

Unfortunately I don't, but I am just as anxious to hear the answers.

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.

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 believe you can only add two filters. One can be for CW and one for
SSB or both for one mode.

Thanks

OK
Just got both of them, and after an easy installation want to say that
they are well worth the trouble.
On crowded bands the narrow filter (FL223) makes an enormous difference
in the ability to copy weaker stations 3kc away from adjacent stronger
ones, and the slight degradation in audio fidelity is quite an
acceptable tradeoff.
I also like to listen to AM broadcast band DX, and the ability to use
SSB mode to dig out the weaker stations next to strong ones now has
improved fidelity with the wider filter (FL103), while still rejecting
the splatter from excessively "OptiModded" locals.
...anxiously awaiting the D layer opening this evening g
Thank you
