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


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
