Hi,
i own a KX3 since June 2012 (one of the first arrived in Italy) . 
I mainly use my KX3 in Phone and CW modes.

Some weeks ago i've bought a SignaLink USB II interface + KX3 cables.

After the initial setup all worked fine in PSK31 and RTTY but i have some 
doubts about the right Mode to use: USB, AFSK A or DATA A

With AFSK A mode the bandwith is too narrow (the waterfall of MixW shows only 
300 Hz more/less) so is usefull only when i've centered the RTTY signal of the 
correspondance.
Not usefull during normal DX operation (IMHO).

Data A is also OK but i can't decode RTTY (only PSKxx modes). In this Mode i 
could narrow the BW but there is no way to decode RTTY correctly.

USB is the Mode i currently use with RTTY but i think is not the right Mode for 
digital communication (i have to manually disable compression and TX Eq. every 
time and setup ALC levels).

I've read and re-read the user manual at Page 18 but i not understand why i 
can't decode RTTY.

So please can someone help me to resolve the problem?

Another question: is there a way to widen the BandWith in AFSK-A Mode ? (my 
display show 0,50 Max).

My KX3 is equipped of the roofing filters.

Many thanks for any help.
